PRESENTATION OF FINANCIAL INFORMATION

In this annual report, references to “real”, “reais” or “R$” are to the Brazilian real, the official currency of Brazil.
All references to “U.S. dollars” or “US$” are to United States dollars.  Solely for the convenience of the reader, we
have  translated  some  of  the  real  amounts  contained  in  this  annual  report  into  U.S.  dollars  at  a  rate  equal  (unless
otherwise indicated) to R$2.6544 to US$1.00, the commercial selling rate on December 31, 2004 as reported by the
Central Bank of Brazil, or the Central Bank.  As a result of the recent fluctuations in the real/U.S. dollar exchange
rate, the commercial selling rate may not be indicative of current or future exchange rates.  Therefore, you should
not  read  these  translations  as  representations  that  any  such  amounts  have  been,  could  have  been  or  could  be
converted into U.S. dollars at that or at any other exchange rate.  See “Item 3. Key Information—Exchange Rates”
for information regarding exchange rates allocable to the Brazilian currency since January 1, 2000.

Our audited financial statements as of December 31, 2003 and 2004 and for  the  years  ended December 31,  2002,
2003 and 2004 are included in this annual report.  The financial statements for the year ended December 31, 2002
have  been  audited  by  PricewaterhouseCoopers  Auditores  Independentes,  São  Paulo,  Brazil,  and  the  financial
statements  as  of  and  for  the  years  ended  December  31,  2003  and  2004  have  been  audited  by  Deloitte  Touche
Tohmatsu Auditores Independentes, São Paulo, Brazil.

Our audited financial statements are presented in reais and are prepared in accordance with Corporate Law Method,
which are based on the Brazilian corporation law (Law No. 6,404/76, as amended), the rules and regulations issued
by  the  Comissão  de  Valores  Mobiliários  (CVM),  or  the  Brazilian  securities  commission,  and  the  accounting
standards issued by the Brazilian Institute of Independent Auditors (Instituto dos Auditores Independentes do Brasil,
or IBRACON), hereinafter referred to as the “Corporate Law Method”.

Like other Brazilian companies, we have the option of presenting our primary financial statements on the basis of
accounting principles established in accordance with the Corporate Law Method with a reconciliation to generally
accepted  accounting  principles  in  the  United  States  of  America  (“U.S.  GAAP”).    Unless  otherwise  indicated,  our
financial statements and all financial data included in this annual report have been prepared in accordance with the
Corporate Law Method.

The  Corporate  Law  Method  differs  in  significant  respects  from  U.S.  GAAP.    Note  23  to  our  audited  financial
statements  provides  a  description  of  the  differences  between  the  Corporate  Law  Method  and  U.S.  GAAP  as  they
relate to our financial statements and a reconciliation from the Corporate Law Method to U.S. GAAP, for periods
presented  therein,  of  our  net  income  (loss)  and  shareholders’  equity.    The  reconciliation  from  the  financial
statements  prepared  in  accordance  with  the  Corporate  Law  Method  to  U.S.  GAAP  includes,  among  others,
adjustments  for  differences  related  to  the  accounting  for  past  revaluations  of  property,  plant  and  equipment,
historical inflation accounting and accounting for pension and other employee benefits.

We do not have any subsidiaries.

Some figures in this annual report may not total due to rounding adjustments.

(2) The extraordinary item charged to income in the years ended December 31, 2002, 2003 and 2004 relates to the amortization (over a five-
year period) of the actuarial liability recorded on December 31, 2001 upon first time recognition of the defined benefits pension plan.  The
presentation  of  the  charge  as  an  extraordinary  Item is  consistent  with  the  instructions  of  the  CVM  and  the  Corporate  Law  Method.    For
purposes of U.S. GAAP, the pension expense has been treated as a payroll expense from the first year presented.

(3) Short and long-term receivables from shareholders, net represent amounts due from the State for water and sewage services.  Amounts as of
December 31, 2003 and 2004 are reflected net of R$401.7 million and R$105.5 million, respectively, of amounts due to the State related to
interest  on  shareholders’  equity  which  has  been  designated  for  reciprocal  offset  under  the  terms  of  the  agreement  executed  among  the
parties, as amended.  See note 6 to our audited financial statements.

(4) Based upon the audited statements of cash flows for the years ended December 31, 2004, 2003 and 2002 included in note 24 to our audited
financial statements and the audited statement of cash flows for the years ended December 31, 2000 and 2001 which are not included in this
annual report.

(5) Adjusted EBITDA means net income (loss) before financial expenses, net, income tax and social contribution tax (a federal tax on income),
depreciation and amortization, non-operating income (expenses), net and extraordinary item, net of income tax and social contribution tax.
Adjusted  EBITDA  is  not  a  measurement  recognized  under  Brazilian  accounting  principles,  does  not  represent  cash  flow  for  the  periods
presented  and  should  not  be  considered  as  an  alternative  to  net  income  (loss),  as  an  indicator  of  our  operating  performance  or  as  an
alternative to cash flows as an indicator of liquidity.  Our definition of Adjusted EBITDA may not be comparable with EBITDA as defined

under  the  Corporate  Law  Method,  our  management  uses  it  to  measure  our  operating  performance  and  it  is  commonly  used  by  financial
analysts in evaluating our business.  Adjusted EBITDA is calculated as follows:

Includes  both  physical  and  non-physical  losses.    Water  loss  percentage  represents  the  quotient  of  (a) the  difference  between  (i) the  total
amount of water produced by us (after excluding certain non-physical water losses set out below) less (ii) the total amount of water invoiced
by us to customers divided by (b) the total amount of water produced (after excluding certain non-physical water losses set out below) by
us.  We exclude from our calculation of water losses the following:  (1) water discharged for periodic maintenance of water mains and water
storage  tanks;  (2) water  supplied  for  municipal  uses  such  as  firefighting;  (3) water  we  consume  in  our  facilities;  and  (4) estimated  water
losses associated with water we supply to favelas (shantytowns).

Exchange Rates

Before  March  14,  2005,  there  were  two  principal  legal  foreign  exchange  markets  in  Brazil,  in  which  rates  were
freely negotiated but could be strongly influenced by Central Bank intervention:

• 

• 

the commercial rate exchange market, dedicated principally to trade and financial foreign
exchange transactions such as the buying and selling of registered investments by foreign entities,
the purchase or sale of shares or the payment of dividends or interest with respect to shares; and

the floating exchange market that was generally used for transactions not conducted through the
commercial foreign exchange market.

On March 4, 2005, the National Monetary Council enacted Resolution No. 3,265, pursuant to which the commercial
rate exchange market and the floating rate exchange market were unified in a sole exchange market, effective as of
March 14, 2005.  The new regulation allows, subject to certain procedures and specific regulatory provisions, the
purchase  and  sale  of  foreign  currency  and  the  international  transfer  of  reais  by  a  person  or  legal  entity,  without
limitation with respect to the amount involved, provided, however, the transaction is legal and based on economic
grounds.  Foreign currencies may only be purchased through financial institutions domiciled in Brazil authorized to
operate in the exchange market.

6

Following  the  introduction  of  the  real  in  1994  and  through  1998,  the  Central  Bank  maintained  a  band  system
exchange  rate,  under  which  the  exchange  rate  between  the  real  and  the  U.S.  dollar  would  fluctuate  within  a  pre-
established moving band.  In January 1999, due to market pressures, the Central Bank abolished  the  band  system
and allowed the real/U.S. dollar exchange rate to float freely.  Since then, the exchange rate has been established by
the market and has fluctuated considerably, reporting a maximum quotation of R$3.955 per U.S.$1.00 on October
22,  2002.    Since  the  liberalization  of  the  exchange  rate,  the  Central  Bank  has  intervened  occasionally  to  control
unstable  movements  in  the  foreign  exchange  rate.    It  is  not  possible  to  predict  whether  the  Central  Bank  will
continue to let the real float freely or whether the real will remain at its present level.  Accordingly, it is not possible
to predict what impact the Brazilian government’s exchange rate policies may have on us.

The  following  table  shows  the  commercial  selling  rate  for  U.S.  dollars  for  the  periods  and  dates  indicated.    The
information in the “Average” column represents the average of the exchange rates for the period indicated.

Risk Factors

Risks Relating to our Control by the State of São Paulo

We are controlled by the State, whose interests may be contrary to the interests of holders of our shares or ADSs.

The State of São Paulo, which we refer to as the State, through its ownership of our common shares, has the ability
to control the election of a majority of the members of our Conselho de Administração (“Board of Directors”), to
appoint  our  senior  management  and  to  determine  our  operations  and  strategy.    The  State  owned  50.3%  of  our
outstanding common shares as of March 31, 2005 and 50.3% of our outstanding common shares as of December 31,
2004.

The State has from time to time in the past used, and may in the future use, its controlling interest in our company to
direct that we engage in certain business activities and make certain expenditures which are designed primarily to
promote the political, economic or social goals of the State and not necessarily to enhance our business and results
of operations.  As a result, actions taken by the State in relation to Sabesp could be contrary to the interests of the
holders of our shares or ADSs.

Most of our Board of Directors and senior management are political appointees of the Governor of the State, who
are subject to periodic change unrelated to our business needs.

Newly-elected  Governors  of  the  State  typically  make  significant  changes  in  our  Board  of  Directors  and  senior
management and, historically, the Chairman of our Board of Directors has been the Secretary of the Energy, Water
Resources and Sanitation Secretariat of the State.  In 2002, the current Governor, Mr. Geraldo Alckmin, appointed
new senior officials for his administration, including Mr. Mauro Guilherme Jardim Arce as the new Secretary of the
Energy,  Water  Resources  and  Sanitation  Secretariat  of  the  State.    Mr. Arce  was  also  elected  as  Chairman  of  our
Board of Directors.  Changes in government or government policy could lead to changes in our senior management
which  in  turn  could  have  a  material  adverse  effect  on  our  business  strategy,  cash  flows,  results  of  operations,
financial condition or prospects.

We  have  accounts  receivable  owed  by  the  State  and  some  State  entities,  as  well  as  a  substantial  amount  of
negotiated long-term receivables owed by the State, and we cannot assure you as to when or whether the State
will pay amounts owed to us.

Historically, the State and some State entities have had substantial overdue accounts payable to us relating to (1) the
provision  of  water  and  sewage  services  and  (2)  State-mandated  special  retirement  and  pension  payments  that  we
make to some of our former employees for which the State is required to reimburse us.  As of December 31, 2004,
the amounts owed to us by the State for the provision of water and sewage services included R$245.6 million, which
was considered overdue as of February 29, 2004.  This amount does not include R$105.5 million which the State
agreed  to  apply  in  respect  of  dividends  payable  to  it  as  part  of  its  agreement  with  us  as  discussed  below.    As  of
December 31, 2004, the State owed us an additional R$48.5 million in accounts receivable related to the provision
of water and sewage services rendered from February 2004.  With respect to reimbursement for pensions paid on
behalf  of  the  State,  the  State  owed  us  R$576.3 million  as  of  December  31,  2004  (R$320.6 million  of  which  was
acknowledged  by  the  State  in  an  agreement  with  us  subject  to  a  further  audit  which  has  not  yet  occurred,  as
discussed below).  We expect amounts owed to us by the State for water and sewage services and reimbursements
for pensions paid to increase in the future.  We have not established any provisions for any amounts due to us by the
State.

In September 1997, December 2001 and March 2004, we entered into agreements with the State to settle overdue
amounts payable to us.  Under the terms of these agreements, the amounts may be settled through the application of
dividends payable by us to the State and by the transfer to us of certain reservoirs in the Alto Tietê System which we
use,  but  which  are  owned  by  the  State.    However,  the  agreements  do  not  require  the  State  to  apply  all  dividends
payable by us to them to the repayment of amounts owed to us.  Since the State entered into these agreements it has
applied the dividend received from us to the repayment of amounts it owes to us.

8

Under the December 2001 agreement, we converted a substantial amount of overdue accounts receivable due from
the  State  and  some  State  entities  into  long-term  accounts  receivable.    According  to  the  March  2004  agreement,
which  amended  the  December  2001  agreement,  the  State  recognized  a  debt  with  us  in  the  amount  of
R$581.8 million regarding unpaid receivables up to February 29, 2004 and we recognized an amount owed to the
State as dividends declared in the form of interest on shareholders’ equity totaling R$518.7 million.

We  cannot  assure  you  as  to  when  or  if  the  State  will  pay  overdue  amounts  due  to  us  by  it  and  by  some  State-
controlled  entities.    Furthermore,  due  to  the  State’s  history  of  not  making  timely  payments  to  us  in  respect  of
services provided by us and of not reimbursing us in a timely manner for the State-mandated special retirement and
pension payments, we cannot assure you that the amount of accounts receivable owed to us by the State and some
State entities will not significantly increase in the future.  If the State does not pay the amounts it owes us, our cash
flows, results of operations and financial condition will be adversely affected.

We expect that a portion of long-term accounts payable by the State to us will be settled by the transfer to us of
State-owned  reservoirs  in  the  Alto  Tietê  System,  but  we  cannot  assure  you  of  the  value  to  be  given  to  these
reservoirs or of the timing or legality of these transfers.

Under the terms of the December 2001 agreement referred to above, the State agreed to transfer the reservoirs in the
Alto Tietê System to us in exchange for the cancellation of a portion of the accounts receivable due from the State
and of reimbursements due from the State for State-mandated special pension payments we have made.  Under the
terms  of  the  agreement,  the  value  of  these  reservoirs  should  be  determined  by  an  appraisal  process  prior  to  their
transfer and amounts owed to us from the State are subject to an audit by a State-appointed auditor.

In July and August 2002, a State-owned construction company, on behalf of the State, and an independent appraisal
firm,  on our  behalf, presented  their  valuation  reports  relating  to  the  reservoirs.    The  appraisals  contained  in  these
reports  were  in  the  amounts  of  R$335.8 million  and  R$341.2 million,  respectively.    Under  the  terms  of  the
December  2001  agreement,  the  arithmetic  average  of  these  appraisals  will  be  deemed  to  be  the  fair  value  of  the
reservoirs.    Because  we  had  already  made  investments  in  these  reservoirs  by  then,  the  arithmetic  average  of  the
appraisals  submitted  to  our  Board  of  Directors  by  August  2002,  R$300.9 million,  was  net  of  a  percentage
corresponding to these investments.  However, a final determination as to the fair value of these reservoirs is still
pending and we cannot assure you as to when the reimbursement of the pension payments will take place.

In addition, on October 29, 2003, the Public Attorney of the State (Ministério Público do Estado de São Paulo), on
behalf of the people of the State, brought a civil public action in a Trial Court of the state of São Paulo (12a Vara da
Fazenda  Pública  do  Estado  de  São  Paulo)  alleging  that  a  transfer  to  us  of  ownership  of  the  Alto  Tietê  System
reservoirs from the State Department of Water and Energy of the State would be illegal.  In October 2004, the court
ruled in favor of the Public Attorney of the State.  In response, we filed an appeal, which is pending final decision
and the State successfully filed an action suspending the lower court’s decisions until final judgment is reached by
the  Court of Appeals of  the state  of  São  Paulo  (Tribunal  de  Justiça  do  Estado  de  São  Paulo).    We  are  unable  to
predict whether we will succeed in appealing such decision and cannot assure you as to whether the transfer of these
reservoirs will occur.

The State has agreed to reimburse us for pension benefits owed to us; however, if agreement is not reached with
respect to the amounts of these reimbursements or if the State delays in making these payments, our cash flows,
results of operations and financial condition could be adversely affected.

The December 2001 agreement also provided that the State’s legal advisors would carry out specific analyses, which
have  commenced,  to  ensure  agreement  among  the  parties  as  to  the  methodology  employed  in  determining  the
amount  of  reimbursement  for  pension  benefits  owed  to  us  by  the  State.    The  commencement  of  reimbursement
payments  with  respect  to  pension  amounts  owed  to  us  by  the  State  has  been  postponed  until  these  analyses  are
completed, the appraisal report is approved and the credit assignments relating to the transfer of the reservoirs in the
Alto Tietê System are formalized.  In addition, the transfer of these reservoirs is currently being disputed and we are
not certain whether such transfer will be legally allowed, as discussed above.  Under the December 2001 agreement,
the original first payment was to be made in July 2002. Negotiations are still ongoing between the Company and the
State  with  a  view  to  restatement  of  the  debt  for  supplemental  retirement  and  pension  benefits,  under  the  terms

9

defined in the December 2001 agreement, including amounts due after November 2001.  These negotiations will be
consolidated  in  a  second  amendment  to  the  December  2001  agreement.    The  Company  will  retain  Fundação
Instituto de Pesquisas Contábeis, Atuarías e financeras (“FIPECAFI”) to validate the actual values to be reimbursed
by the State, provided by the Office of the State Attorney General.  We  cannot  assure  you  as  to when  agreement
among the parties will be reached or when the State will commence making payments in respect of these amounts.
If  an  agreement  among  the  parties  is  not  reached  or  if  the  State  delays  or  fails  to  make  such  payments,  our  cash
flows, results of operations and financial condition could be adversely affected.

We may be required to acquire reservoirs that we use and that are owned by a State-controlled company, or we
may  be  required  to  pay  substantial  fees  to  the  owner  in  the  form  of  rent  and  additional  operational  and
maintenance expenses with respect to our use of such reservoirs.

In connection with the provision of water services, we use the Billings and Guarapiranga reservoirs that are owned
by a State-controlled company.  The State, through its control of our Board of Directors, could require us to acquire
the Billings and Guarapiranga reservoirs.  As a result of these acquisitions, our cash position and overall financial
condition could be adversely affected.  In addition, since we are not currently charged for the use of these reservoirs,
we are uncertain as to whether in the future we will continue to be able to use the reservoirs without paying a fee, or
what  the  likely  fee  scale  would  be,  if  imposed.    We  may  also  be  required  to  pay  additional  maintenance  and
operational costs for our use of the Billings and Guarapiranga reservoirs.  If we were required to pay substantial fees
to the owner or additional maintenance or operational costs for these properties, our cash flows, results of operations
and financial condition could be adversely affected.

Risks Relating to Our Business

The basic sanitation sector is not specifically regulated in Brazil and the approval of any proposed regulations for
the  water  and  sewage  industry  may  negatively  affect  our  operations  in  the  São  Paulo  Metropolitan  Region,  as
well as in other areas that we serve.

There  is  not,  at  the  present  time,  any  specific  regulation  in  connection  with  sanitation  services  in  Brazil.
Accordingly, the Brazilian Federal Congress has, from time to time, discussed proposals for regulation, which would
establish directives for basic sanitation services.  Any proposed regulation, when and if approved, could establish a
new  municipal  regulatory  authority  for  our  industry  that  may,  in  part,  preempt  the  existing  State  regulatory
authorities under which we operate in the Metropolitan Region.  In addition, a new regulation could modify the way
we charge for our water and sewage services businesses, as well as our capital expenditure program.  Any of these
changes could have an adverse effect on our revenue, by causing us to lose concessions we currently hold, or on our
operating margins, by limiting our ability to pass our cost on to our customers.

As of the date of this annual report, no proposed federal regulation for the water and sewage industry has been voted
on  by  the  Brazilian  Federal  Congress.    We  cannot  anticipate  if,  when  or  in  which  terms  any  proposed  federal
regulation  will  become  effective.    Any  of  the  proposed  new  regulations,  if  approved  by  the  Brazilian  Federal
Congress, could have a negative effect on our operations in the São Paulo Metropolitan Region, as well as in other
areas that we serve.

We may become subject to substantial water-related and sewage-related charges imposed by governmental water
agencies of the State and of the Federal Government.

Governmental water agencies of the State may be, and the Federal Government is, authorized to collect fees from
entities,  including  us,  that  either  abstract  water  from,  or  dump  sewage  into,  water  resources  controlled  by  these
agencies.    The  fees  collected  by  these  agencies  are  to  be  used  to  sponsor  studies,  programs,  projects  and
constructions  provided  for  in  the  Water  Resources  Plan  (Plano  de  Recursos  Hídricos)  and  for  the  payment  of
expenses  concerning  the  creation  of  the  Federal  System  for  Water  Resources  Managing  (Sistema  Nacional  de
Gerenciamento de Recursos Hídricos), as well as administrative costs regarding the bodies and entities pertaining
thereto  and  they  may  be  loaned  or  provided  as  grants  or  subsidies  to  governmental  agencies  and  corporations,
including us, for use in the development and maintenance of water resources.  The legislature of the State  is  also
debating new  legislation  that  would  establish  procedures  for  the  collection  of  these  fees.   In  addition,  the Federal

10

Government enacted legislation under which we must pay fees to the Federal Government or an agency in respect of
the use of water from specified sources.  We are uncertain as to the likely fees that may be assessed, or whether we
will be able to pass on the cost of any of these fees to our customers.

We  have  accounts  receivable  due  from  municipalities  and  we  cannot  assure  you  as  to  when  or  whether  these
municipalities will pay us.

As  of  December  31,  2004,  we  had  accounts  receivable  totaling  R$632.2 million  from  municipalities  to  which  we
provide  water  on  a  wholesale  basis.    Of  this  amount,  R$100.6 million  was  91  to  360  days  overdue  and
R$462.6 million  was  more  than  360  days  overdue.    In  some  cases,  the  Brazilian  courts  have  required  that  we
continue to provide water on a wholesale basis to municipalities, even if they fail to pay our invoices.  Additionally,
as  of  December  31,  2004,  we  had  accounts  receivable  in  the  amount  of  R$305.9 million,  owed  to  us  by
municipalities to which we render water and sewage services, including R$226.6 million owed by the Municipality
of the City of São Paulo.

Although  we  have  entered  into  negotiations  with  municipalities  to  reschedule  such  accounts  receivable  and  have
also filed legal proceedings against municipalities to collect the overdue amounts, some municipalities are currently
not  paying  our  invoices  in  full  or  on  a  timely  basis.    In  addition,  some  governmental  entities  located  in
municipalities we serve are also not paying us on a regular basis.  We cannot assure you as to whether or when these
municipalities will resume making regular payments or pay overdue amounts owing to us.  If these municipalities
and  government  agencies  do  not  pay  amounts  they  owe  us,  our  cash  flows,  results  of  operations  and  financial
condition will be adversely affected.

We do not hold formal concessions for the City of São Paulo and several other municipalities that we serve, and
therefore we may not be able to enforce our rights to continue to provide services in these municipalities.

We do not hold formal concessions in the City of São Paulo, which on December 31, 2004 accounted for 56.1% of
our  sales  and  services  rendered,  or  in  40  other  municipalities  in  the  state  of  São  Paulo.    Because  we  do  not  hold
concessions or formal contract rights to provide services in these municipalities, we may not be able to effectively
enforce our right to continue to provide services or to be paid for the services we provide.  In the future, our rights in
respect of the City of São Paulo and these other municipalities could be modified or adversely affected by Brazilian
federal, state or local governmental actions or other factors.

From time to time, mayors of the City of São Paulo have initiated or proposed discussions with the State regarding
entering into a formal concession contract with us to provide water and sewage services in the City of São Paulo.
The  City  of  São  Paulo  legislature  approved  Law  13,670  of  November  25,  2003  through  which  it  intended  to
establish  the  authority  to  regulate  its  public  water  supply  and  sewage  services.    Following  the  enactment  of  Law
No. 13,670,  the  Governor  of  the  State  filed  a  legal  action  alleging  that  the  law  is  unconstitutional,  as  a  result  of
which the enforcement of Law No. 13,670 has been suspended.  On April 20, 2005, the court ruled in favour of the
Governor of the State, by a majority of votes; the court’s judgement had not yet been drawn up as of the date of this
annual report.  We cannot assure you when or if the suspension of Law 13,670 will end, and we cannot anticipate
the  effect of  its renewed  application which  could result  in  the  City  of  São  Paulo  granting  us  a  formal  concession
contract under terms and conditions different to those under which our services are currently provided, or even in the
termination of our ability to provide our services as currently provided.

Municipalities for which we hold concessions may choose not to renew their concessions to us.

We provide water and sewage services in 326 municipalities pursuant to concessions granted by the municipalities.
Substantially all of these concessions have 30-year terms:  273 of these concessions expire between 2005 and 2010,
of which 17 are scheduled to expire in 2005 and 127 are scheduled to expire in 2006; and the rest expire between
2011 and 2034.  The Botucatu concession, one of our significant concessions, expired on October 18, 2004.  The
municipality of Botucatu issued a Municipal Decree on October 19, 2004 extending our concession for an additional
12  months  and  we  are  currently  in  discussions  to  renew  this  concession  for  30  years.    A  majority  of  these
concessions are automatically renewable for a period equal to their initial term, although we often renegotiate terms
and conditions, unless we or the municipality exercise the right to terminate the concession prior to the six-month

11

period ending on the expiration date of the concession.  Any termination of a concession could adversely affect our
cash  flows,  results  of  operations  and  financial  condition.    If  certain  municipalities  choose  not  to  renew  their
concessions,  it  could  adversely  affect  our  cash  flows,  results  of  operations  and  financial  condition.    Even  if  they
choose to renew these concessions, we cannot assure you that we will obtain the same terms that we currently have.

Municipalities may terminate our concessions for any “good public reason” or if we fail to meet our contractual
obligations.

Municipalities  may  terminate  our  concessions under  some  circumstances,  including  if  we  fail  to  comply  with  our
obligations under the relevant concession contracts.  In addition to contractual termination provisions in concession
contracts,  municipalities  have  the  inherent  power  under  Brazilian  law  to  terminate  concessions  prior  to  their
contractual  expiration  dates  for  any  “good  public  reason.”    The  meaning  of  “good  public  reason”  has  not  been
defined  by  Brazilian  law  or  conclusively  determined  by  Brazilian  courts.    In  the  event  of  the  termination  of  a
concession,  we  may  receive  inadequate  compensation  from  the  concessionaire  municipality.    We  may  also  incur
material  litigation  costs  related  to  termination  of  concessions  and  compensation.    The  Constitution  of  the  State
establishes that the municipalities in which we operate as water and sewage service providers may, in the course of
granting  authority  over  these  services,  create  their  own  autonomous  entities  to  render  such  services  in  their
territories instead of continuing to use our services, with the obligation to indemnify us for the termination of the
concession with us over a  term  of  up  to  25  years  rather  than  at  the  time  the  concession  is  terminated.    The  State
obtained  an  injunction  in  a  legal  action  alleging  this  indemnification  to  be  unconstitutional.    As  a  result,  the
maximum term for payment of the indemnification has been suspended.  In the event that this injunction is stayed
and/or  the  outcome  of  the  legal  action  is  not  favorable  to  us,  the  indemnification  over  a  term  of  25  years  may
adversely affect our operational results and financial condition.  In 1997, the Municipality of Santos enacted a law
expropriating our water and sewage systems in Santos.  In response, we filed an action seeking an injunction against
this expropriation which was denied by the lower court.  This decision was later reversed by the Court of Appeals of
the State, which issued a preliminary order suspending that law.  On August 2, 2002, a decision on this matter was
rendered in our favor by a lower court.  This decision is still subject to appeal, and we cannot assure you that the
ultimate  determination  will  be  favorable  to  us.    Despite  the  pending  lawsuit,  we  continue  to  provide  water  and
sewage services to Santos.

We cannot assure you that other municipalities will not seek to terminate their concessions.  Exercise of concession
termination rights by substantial numbers of municipalities could have a material adverse effect on our cash flows,
results of operations and financial condition.

We  may  be  required  to  compete  through  a  public  bidding  process  in  order  to  obtain  new  or  renew  existing
concessions.

Substantially all of our concessions were granted without a public bidding process.  Under current Brazilian Federal
and State law, however, for any new concession we may be required to participate in a bidding process.  In addition,
if a public entity from which we hold a concession granted prior to the enactment of the concession laws determines
that in order to comply with such laws it must engage in a public bidding process, we could be required to compete
in order to renew our existing concession.  While we may be able to obtain concessions without participating in a
bidding process, we  cannot  assure  you  that  the  Brazilian  courts  will  continue  to  interpret  the  concessions  laws  to
permit municipalities to grant concessions without a public bidding process or that we will be able to secure all new
water and sewage concessions that we may wish to obtain.

In the event we are obligated to participate in public bidding processes in order to renew our existing concessions or
to obtain new ones, our failure to outbid our competitors for our existing concessions may adversely impact our cash
flows, results of operations and financial condition.

We  may  be  unable  to  increase  customer  tariffs  in  line  with  increases  in  inflation  and  operating  expenses,
including taxes.

Our results of operations and financial condition are highly dependent upon our ability to set and collect adequate
tariffs for our water and sewage services.  Although we generally have broad power to establish tariffs, this power

12

is, in practice, subject to political and legal constraints.  From mid-1999 until mid-2001 we did not raise our tariffs,
due to a State policy of not increasing tariffs for public services.  In June 2001, we increased our average tariffs by
approximately 13.1% which was broadly in line with the prevailing inflation rates in Brazil since mid-1999, and in
August 2002 we raised our tariffs by approximately 8.2%.  A new readjustment formula was approved by our Board
of Directors and was applied to the tariff adjustment of August 2003 and 2004, however, we are not certain if we
will be able to use this formula in the future.  Using this new formula, in August 2003 we raised our tariffs for water
and  sewage  services  by  approximately  18.9%,  and  in  August  2004  we  raised  our  tariffs  for  water  and  sewage
services  by  approximately  6.8%.   Tariffs  with  respect  to  the  residential  social  (which  includes  residences  of  low-
income  families  that  live  in  sub-standard  conditions,  residences  of  persons  unemployed  for  up  to  12  months  and
collective living residences) and favela (shantytown) categories, are not always increased at the same rate as other
tariffs.    For  example,  in  August  2003,  these  tariffs  were  increased  by  only  9.0%  and  were  not  set  using  the  new
formula.    We  will  continue  to  rely  upon  tariff  revenue  to  provide  funds  for  our  capital  expenditure  program  in
addition to our financing activities and to meet our debt service requirements.  We are currently conducting studies
with  a  view  to  implementation  of  a  new  tariff  policy.    However,  we  cannot  assure  you  when  and  if  a  new  tariff
policy  will  be  implemented  or  if  such  implementation  will  meet  our  expectations.    Any  failure  to  establish  or
maintain tariffs commensurate with these and our other needs could have an adverse effect on our cash flows, results
of operations and financial condition.

Our  capital  expenditure  program  requires  substantial  liquidity  and  capital  resource,  and  any  failure  to  obtain
new financing may have a material adverse effect on the operation and development of our business.

Our  capital  expenditure  program  calls  for  expenditures  of  approximately  R$4.2  billion  in  the  period  from  2005
through  2009,  including  approximately  R$758.1  million  in  2005  and  R$880.0  million  in  2006.    We  spent
approximately R$600.9 million on our capital expenditure program in 2004.

We  have  funded  in  the  past,  and  we  plan  to  continue  to  fund,  these  expenditures  out  of  funds  generated  by
operations and domestic and foreign currency borrowings on acceptable terms.  In this way, a significant portion of
our financing needs has been funded by financing provided by lenders controlled by the Federal Government.  For
example, we are currently negotiating with the Brazilian Economic and Social Development Bank (Banco Nacional
de  Desenvolvimento  Econômico  e  Social,  or  “BNDES”),  and  Caixa  Econômica  Federal  (a  bank  owned  by  the
Brazilian government) for additional loans to finance portions of our capital expenditure program.  We also benefit
from long-term financing from domestic and international multilateral agencies and development banks at attractive
interest  rates.    Changes  in  the  policies  of  the  Federal  Government  regarding  the  financing  of  water  and  sewage
services, or our failure to continue to benefit from long-term financing from domestic and international multilateral
agencies and development banks at attractive interest rates may impair our ability to finance our capital expenditure
program.

We cannot assure you that we will be able to obtain sufficient funds to complete our capital expenditure program .
Failure to obtain the requisite funds could delay or prevent completion of our capital expenditure program and other
projects, which may have a material adverse effect on the operation and development of our business.

Brazilian regulations as well as contractual provisions may limit our ability to incur indebtedness in the future.

Because we are controlled by the State we are subject to special credit rules for the public sector published by the
Brazilian monetary authorities.  As a general rule, financial institutions and other institutions authorized to provide
credit by the Central Bank may only provide loans to public sector entities, such as us, up to a certain percentage of
such entities’ net equity.  In addition, new loans in connection with certain water and sewage activities may only be
given up to certain pre-established amounts.  Because of these limitations on our ability to obtain credit from private
financial  institutions,  our  options  for  raising  funds,  other  than  the  cash  generated  by  our  operations,  consist
principally  of  borrowing  from  State-owned  financial  institutions  or  development  agencies  and  issuing  bonds  and
other publicly traded obligations.  These limitations on obtaining credit could adversely affect the development of
our business, our ability to meet our obligations or continue our capital expenditure program, and our cash flows,
results of operations and financial condition.

13

Under  our  existing  debt  instruments,  we  are  subject  to  covenants  limiting  our  ability  to  incur  additional
indebtedness, whether denominated in reais or foreign currency.  Under these covenants, we would have been able
to borrow up to an additional R$1,107.2 million as of December 31, 2004.  If, however, these and other limitations
prevent us from completing our capital expenditure program or executing our business plans generally, we may be
unable to satisfy all of our liquidity and capital resources requirements, which could have a material adverse effect
on our cash flows, results of operations and financial condition.

Droughts may result in a decrease in the volume of water billed and the revenue from water supplies, which may
have a material adverse effect on our company.

We experience decreases in our water supply from time to time due to droughts.  In the event of prolonged drought,
the volume of water provided by us may be reduced, although the impact that droughts have may vary across our
different water supply systems.  Throughout 2003, rain levels were below average resulting in a weak replenishment
of  our  reservoirs, particularly  in  the  Cantareira System,  the  largest  system  in  the  São  Paulo  Metropolitan  Region.
The effects of this drought continued to impact our systems through 2004.  In order to minimize the effects of this
drought, in March 2004 we approved a water consumption reduction incentive program based on a bonus system,
pursuant to which customers that achieved their consumption reduction goal would be entitled to a 20.0% discount
on their water bill.  This incentive program ended on September 15, 2004 and encompassed most of the customers in
the São Paulo Metropolitan Region, resulting in a reduction of our revenue from water and sewage services provided
to the São Paulo Metropolitan Region by R$74.1 million.  We cannot assure you that any drought in the future will
not materially adversely affect our water supply and, accordingly, our cash flows, results of operations and financial
condition.

Potential  costs  of  environmental  compliance  as  well  as  potential  environmental  liability  may  have  a  material
adverse effect on our company.

Our facilities are subject to many Brazilian federal, state and local laws and regulations relating to the protection of
health  and  the  environment.    We  have  made,  and  will  continue  to  make,  substantial  expenditures  to  comply  with
these provisions.  In addition, because environmental laws and their enforcement are becoming more stringent, our
capital  expenditures  and  expenses  for  environmental  compliance  may  increase  substantially  in  the  future.    The
amount of investments that we make in any given year is subject to limitations imposed by the State.  Expenditures
required for compliance with environmental regulation may result in reductions in other strategic investments that
we  have  planned,  which  could  negatively  affect  our  profitability.    We  could  also  be  exposed  to  criminal  and
administrative  penalties,  in  addition  to  indemnification  obligations,  for  possible  damage  for  non-compliance  with
environmental  laws  and  regulations.    Currently,  we  are  party  to  a  number  of  environmental  lawsuits  and
administrative  proceedings,  including  civil  public  actions  and  criminal  proceedings.    Any  material  unforeseen
environmental costs and liabilities may have a material adverse effect on our future financial performance.

Any  substantial  monetary  judgment against  us  in  legal proceedings  may  have a material  adverse  effect on our
company.

We are a party to a number  of  legal proceedings  involving  significant  monetary  claims.    These  legal  proceedings
include, among others, tax, labor, condemnation and other proceedings.  A substantial monetary judgment against us
in one or more of these legal proceedings may have a material adverse effect on our business or financial condition.
Based on advice we received from our lawyers, we have provisioned a total aggregate amount of R$490.6 million as
of  December  31,  2004  to  cover  losses  related  to  legal  proceedings  considered  probable.    This  provision  does  not
cover,  however,  all  legal  proceedings  involving  monetary  claims  filed  against  us.    Any  unfavorable  judgment  in
relation  to  these  proceedings  may  have  an  adverse  effect  on  our  cash  flows,  results  of  operations  and  financial
condition.

Because we are not insured for all business-related and environmental-related contingencies, the occurrence of
any such event may have a material adverse effect on our future financial performance.

We  do  not  have  insurance  coverage  for  business  interruption  risk  or  for  liabilities  arising  from  contamination  or
other  problems  involving  our  water  supply  to  customers.    In  addition,  we  do  not  have  insurance  coverage  for

14

liabilities relating to non-compliance with environmental laws and regulations relating to our sewage services.  As a
result, any major business interruption or environmental-related liability may have a material adverse effect on our
future financial performance.

Risks Relating to Brazil

Brazilian economic, political and other conditions may have a material adverse effect on our business.

The Brazilian economy has been characterized by significant involvement on the part of the Brazilian government,
which often changes monetary, credit and other policies to influence Brazil’s economy.  The Brazilian government’s
actions  to  control  inflation  and  affect  other  policies  have  often  involved  wage  and  price  controls,  currency
devaluations, increases in the Central Bank’s base interest rates, capital controls and limits on imports, as  well  as
other measures, such as the freezing of bank accounts.

Actions  taken  by  the  Brazilian  government  concerning  the  economy  may  have  important  effects  on  Brazilian
corporations and other entities, including us, and on market conditions and prices of Brazilian securities, including
our equity and debt securities.  Our financial condition and results of operations may be adversely affected by the
following factors or the Brazilian government’s response to them:

•

•

•

•

•

•

•

•

•

•

currency devaluation and other exchange rate movements;

inflation;

currency exchange control policies;

social instability;

price instability;

energy shortages;

interest rates;

liquidity of domestic capital and lending markets;

tax policy; and

other political, diplomatic, social and economic developments in or affecting Brazil.

Brazil’s President, Luiz Inácio Lula da Silva took office on January 1, 2003.  In the period leading up to his election
and for a period of time thereafter, there was substantial uncertainty relating to the policies that the new government
would  pursue,  including  the  potential  implementation  of  macroeconomic  policies  that  differed  significantly  from
those of the prior administration.  This uncertainty resulted in a lower level of confidence in the Brazilian currency
and  capital  markets,  contributing  to  the  rapid  depreciation  of  the  real  against  the  U.S. dollar  during  that  period.
Although the government has not departed significantly from policies of the previous administration, and the  real
appreciated  22.3%  against  the  U.S. dollar  during  2003  and  further  appreciated  8.8%  during  2004,  there  remains
concern about the policies of the current Brazilian government.  Uncertainty over whether current policies will be
continued  or  whether  the  Brazilian  government  will  adopt  different  policies  in  the  future  may  contribute  to
economic uncertainty in Brazil and to heightened volatility in the Brazilian securities markets and securities issued
abroad that are supported by Brazilian issuers.  Municipal elections took place during 2004.  The next State election
is scheduled to occur in October 2006.  We cannot predict the policies that the newly elected administrations may
adopt,  or  the  effect  those  policies  may  have.    Any  substantial  negative  reaction  to  the  policies  adopted  by  the
Brazilian federal or state government from time to time could adversely affect our cash flows, results of operations,
financial condition and the market price of our shares or ADSs.

15

Devaluation of the real could adversely affect our ability to service our foreign currency-denominated debt, and
could lead to a decline in the market price of our shares or ADSs.

The  Brazilian  currency  has  been  devalued  frequently  during  the  last  four  decades.    Throughout  this  period,  the
Brazilian  government  has  implemented  various  economic  plans  and  utilized  various  exchange  rate  policies,
including sudden devaluations, periodic mini-devaluations (during which the frequency of adjustments has ranged
from  daily  to  monthly),  exchange  controls,  multiple  exchange  rate  markets  and  a  floating  exchange  rate  system.
From time to time, there have been significant fluctuations in the exchange rates between the Brazilian currency and
the  U.S. dollar  and  other  currencies.    For  example,  in  2000,  2001  and  2002,  the  real  devalued  8.5%,  15.7%  and
34.3% respectively, while appreciating 22.3% in 2003 and 8.8% in 2004 against the U.S. dollar.

In the event of a significant devaluation of the real in relation to the U.S. dollar or other currencies, our ability to
meet  our  foreign  currency-denominated  obligations  could  be  adversely  affected,  particularly  because  our  tariff
revenue  and  other  sources  of  income  are  based  solely  in  reais.    In  addition,  because  we  have  substantial  foreign
currency-denominated indebtedness, any significant devaluation of the real during a financial period will increase
our financial expenses as a result of foreign exchange losses that we must record.  We had total foreign currency-
denominated  indebtedness  of  R$2,680.9 million  as  of  December  31,  2004,  and  we  anticipate  that  we  may  incur
substantial amounts of foreign currency-denominated indebtedness in the future.  Our overall results of operations
were  positively  affected  by  the  8.8%  appreciation  of  the  real  against  the  U.S. dollar  in  2004,  which  amounted  to
R$179.7 million.  We do not currently have any hedging instruments in place to protect us against a devaluation of
the  real  in  relation  to  any  foreign  currency.    A  devaluation  of  the  real  would  reduce  the  U.S. dollar  value  of
distributions and dividends on our ADSs and could reduce the market price of our shares or ADSs.

The Brazilian government’s actions to combat inflation and public speculation about possible future action may
contribute significantly to economic uncertainty in Brazil.

Historically, Brazil has experienced high rates of inflation.  Inflation itself as well as governmental efforts to combat
inflation have had significant negative effects on the Brazilian economy in general.  Inflation, action taken to combat
inflation and public speculation about possible future action has also materially contributed to economic uncertainty
in Brazil and to heightened volatility in the Brazilian securities markets.

Inflation, as measured by the General Price Index-Market, or the IGP-M (Índice Geral de Preços de Mercado), was
25.3% in 2002, 8.7% in 2003 and 12.4% in 2004.  There can be no assurance that levels of inflation in Brazil will
not increase in future years and have a material adverse effect on our cash flows, results of operations or financial
condition.    If  Brazil  experiences  significant  inflation  in  the  future,  our  costs  and  expenses  may  rise,  we  may  be
unable  to  increase  our  tariffs  to  counter  the  effects  of  inflation,  and  our  overall  financial  performance  may  be
adversely affected.

In addition, a substantial increase in inflation may weaken investor confidence in Brazil, so that the market price of
our equity and debt securities declines.

Brazilian law might permit claims against our shareholders for harm to the environment.

Brazilian  Law  No. 9,605  of  February  12,  1998  provides  that  the  corporate  structure  of  a  company  may  be
disregarded if it impedes recovery for undue harm to the environment.  We cannot assure you that, in the case of
claim  for  environmental  damage  under  this  law,  liabilities would be  limited  to  shareholders  capable  of  exercising
control  over  the  company  at  the  time  of  such  environmental  damage.    Accordingly,  if  we  were  unable  to  redress
claims against us for environmental damages, which might happen, for example, if we were to become insolvent,
our shareholders and the members of our management might become liable for those claims.  We are not aware of
any successful assertion of claims against any shareholders of any Brazilian corporation under this law and cannot
predict the circumstances in which this might happen.

16

Because electrical power is essential to our operations, power shortages, rationing or instability of the electricity
supply or significant increases in electricity tariffs may adversely affect our business.

We are one of the major power consumers in the state of São Paulo and the use of electrical power is essential to our
operations.    In  May  2001,  the  Federal  Government  announced  measures  to  reduce  power  consumption  in  several
regions  of  Brazil,  including  areas  where  we  operate.    We  were  not  subject  to  such  measures  because  we  render
essential  services.    However,  instability  of  the  power  supply  has  caused  and  may  cause  in  the  future  material
damages to our water and sewage systems which could adversely affect our business.  In addition, material shortages
or reduction in the power supply (including those due to rationing programs) may adversely impact our results of
operations and financial condition.  Electricity tariffs increased by an average of 17.54% during the course of 2004,
which  in  turn  led  to  a  R$53.5 million  increase  in  our  electric  power  costs  in  2004  compared  to  2003.    Further
significant  increases  in  electricity  tariffs  may  have  an  adverse  impact  on  our  results  of  operations  and  financial
condition.

Risks Relating to our Common Shares and ADSs

Restrictions on the movement of capital out of Brazil may impair the ability of holders to receive dividends and
distributions on, and the proceeds of any sale of, the common shares underlying our ADSs.

The Brazilian government may impose temporary restrictions on the conversion of Brazilian currency into foreign
currencies and on the remittance to foreign investors of the proceeds of their investments in Brazil.  Brazilian law
permits  the  government  to  impose  these  restrictions  whenever  there  is  a  serious  imbalance  in  Brazil’s  balance  of
payments or there are reasons to foresee a serious imbalance.

The  Brazilian  government  imposed  remittance  restrictions  for  approximately  six  months  in  1990.    Similar
restrictions, if imposed, would impair or prevent the conversion of dividends, distributions, or the proceeds from any
sale  of  common  shares,  as  the  case  may  be,  from  reais  into  U.S.  dollars  and  the  remittance  of  the  U.S.  dollars
abroad.  We cannot assure you that the Brazilian government will not take similar measures in the future.  In such a
case, the depositary for our ADSs will hold the reais it cannot convert for the account of the ADR holders who have
not been paid.  The depositary will not invest the reais and it will not be liable for the interest.

Holders of our common shares and ADSs may not receive any dividends or interest on shareholders' equity.

According  to  our  by-laws,  we  must  generally  pay  our  shareholders  at  least  25.0%  of  our  annual  net  income  as
dividends  or  interest  on  shareholders'  equity,  as  determined  and  adjusted  under  the  Corporate  Law  Method.  This
adjusted income may be capitalized, used to absorb losses or otherwise appropriated as allowed under the Corporate
Law Method and may not be avai1able to be paid as dividends or interest on shareholders' equity. We may not pay
dividends  or  interest  on  shareholders'  equity  to  our  shareholders  in  any  particular  fiscal  year  if  our  Board  of
Directors determines that such distributions would be inadvisable in view of our financial condition.

If  a  holder  exchanges  ADSs  for  common  shares,  he  or  she  risks  losing  the  ability  to  remit  foreign  currency
abroad and Brazilian tax advantages.

The Brazilian custodian for the common shares underlying our ADSs must obtain a certificate of registration from
the  Central  Bank  to  be  entitled  to  remit  U.S.  dollars  abroad  for  payments  of  dividends  and  other  distributions
relating to our common shares or upon the disposition of our common shares.  If a holder decides to exchange his or
her ADSs for the underlying common shares, he or she will be entitled to continue to rely — for five business days
from the date of exchange — on the custodian’s certificate of registration.  After that period, the holder may not be
able to obtain and remit U.S. dollars abroad upon the disposition of our common shares, or distributions relating to
our common shares, unless he or she obtains his or her own certificate of registration or register under Resolution
No. 2,689, of January 26, 2000, of the National Monetary Council, which entitles registered foreign investors to buy
and sell on the Brazilian stock exchanges.  If the holder does not obtain a certificate of registration or register under
Resolution No. 2,689, he or she will generally be subject to less favorable tax treatment on gains with respect to our
common shares.

17

If a holder attempts to obtain his or her own certificate of registration, he or she may incur expenses or suffer delays
in the application process, which could delay his or her ability to receive dividends or distributions relating to our
common shares or the return of his or her capital in a timely manner.  We cannot assure you that the custodian’s
certificate  of  registration  or  any  foreign  capital  registration  obtained  by  a  holder  may  not  be  affected  by  future
legislative changes, or that additional restrictions applicable to the holder, the disposition of the underlying common
shares or the repatriation of the proceeds from disposition will not be imposed in the future.

The relative volatility and illiquidity of the Brazilian securities market may substantially limit a holder’s ability to
sell the common shares underlying our ADSs at the prices and time he or she desires.

The  Brazilian  securities  markets  are  substantially  smaller,  less  liquid,  more  concentrated  and  more  volatile  than
major securities markets in the United States and other jurisdictions, and are not as highly regulated or supervised as
some  of  these  other  markets.    The  relatively  small  market  capitalization  and  illiquidity  of  the  Brazilian  equity
markets may substantially limit a holder’s ability to sell the common shares underlying our ADSs at the price and
time he or she desires.

A  holder  of  common  shares  or  ADSs  may  face  difficulties  in  protecting  his  or  her  interests  as  a  shareholder,
because we are subject to different corporate rules and regulations as a Brazilian company and holders may have
fewer and less well-defined shareholders’ rights.

Despite the fact that we are listed on the Novo Mercado segment of the São Paulo Stock Exchange, our corporate
affairs are governed by our by-laws and Brazilian corporate law, which differ from the legal principles that would
apply if we were incorporated in a jurisdiction in the United States, such as the State of Delaware or the State of
New York, or in other jurisdictions outside Brazil.  In addition, the rights of holders of our ADSs or common shares
under the Brazilian corporation law to protect their interests relative to actions by our  Board of Directors  may  be
fewer and less well-defined than under the laws of those other jurisdictions.

Although insider trading and price manipulation are crimes under Brazilian law, the Brazilian securities markets are
not  as  highly  regulated  and  supervised  as  the  U.S.  securities  markets  or  markets  in  some  other  jurisdictions.    In
addition, rules and policies against self-dealing and regarding the preservation of shareholder interests may be less
well-defined and enforced in Brazil than in the United States, putting holders of our common shares and ADSs at a
potential disadvantage.  Corporate disclosures may be less complete or informative than what may be expected of a
U.S. public company.

A  holder  of  common  shares  or  ADSs  may  face  difficulties  in  protecting  his  or  her  interests  as  a  shareholder
because we are a Brazilian company.

We are a mixed capital company (sociedade de economia mista) organized under the laws of Brazil, and all of our
directors  and  officers  and  our  controlling  shareholder  reside in  Brazil.    All  of  our  fixed  assets  and  those  of  these
other persons are located in Brazil.  As a result, it may not be possible for a holder to effect service of process upon
us or  these  other persons  within  the  United States  or other jurisdictions outside  Brazil  or  to  enforce  against  us  or
these other persons judgments obtained in the United States or other jurisdictions outside Brazil.  Because judgments
of  U.S.  courts  for  civil  liabilities  based  upon  the  U.S.  federal  securities  laws  may  only  be  enforced  in  Brazil  if
certain requirements are met, a holder may face difficulties in protecting his or her interests in the case of actions by
our directors, officers or our controlling shareholder than would shareholders of a corporation incorporated in a state
or other jurisdiction of the United States.  In addition, under Brazilian law, none of our assets which are essential to
our ability to render public services are subject to seizure or attachment.  Furthermore, the execution of a judgment
against  our  controlling  shareholder  may  be  delayed  as  payment  of  such  judgment  must  be  made  pursuant  to  the
State’s budget in a subsequent fiscal year.  None of the public property of our controlling shareholder is subject to
execution or attachment, either prior to or after judgment.

18

The  protections  afforded  to  minority  shareholders  in  Brazil  are  different  from  those  in  the  United  States  and
other jurisdictions and may be more difficult to enforce.

Under Brazilian law, the protections afforded to minority shareholders are different from those in the United States
and  other  jurisdictions.  In  particular,  the  case  law  with  respect  to  shareholder  disputes  is  less  developed  under
Brazilian law than under US law and the laws of other jurisdictions and there are different procedural requirements
for  bringing  shareholder  lawsuits,  such  as  shareholder  derivative  suits.  As  a  result,  in  practice  it  may  be  more
difficult for our minority shareholders to enforce their rights against us or our directors or controlling shareholder
than it would be for shareholders of a non-Brazilian company.

Actual or anticipated sales of a substantial number of our common shares could decrease the market prices of
our common shares and ADSs.

Sales  of  a  substantial  number  of  our  common  shares  —  or  the  anticipation  of  such  sales  —  could  decrease  the
trading price of our common shares and ADSs.  As of December 31, 2004, we had 28,479,577,827 common shares
outstanding,  including  14,313,511,872  shares  held  by  the  State.    As  a  consequence  of  the  issuance  of  common
shares or sales by the State or other existing shareholders, the market price of our common shares and, by extension,
our ADSs may decrease significantly.  As a result, a holder may not be able to sell his or her securities at or above
the price he or she paid for them.

Mandatory arbitration provisions in our by-laws may limit the ability of a holder of our ADSs to enforce liability
under US securities laws.

Under our by-laws, any disputes among us, our shareholders and our management with respect to the application of
Novo  Mercado  rules,  the  Brazilian  Corporate  Law  and  the  application  of  the  rules  and  regulations  regarding
Brazilian  capital  markets  will  be  resolved  by  arbitration  conducted  pursuant  to  the  São  Paulo  Stock  Exchange
Arbitration  Rules  in  the  São  Paulo  Stock  Exchange  Arbitration  Chamber.    Any  disputes  among  shareholders,
including holders of ADSs, and disputes between us and our shareholders, including holders of ADSs, will also be
submitted to arbitration.  The State is currently not permitted by law to sell its control shares. As a result, a court in
the United States might require that a claim brought by a holder of ADSs predicated upon the US securities laws be
submitted to arbitration in accordance with our by-laws.  In that event, a purchaser of ADSs would be effectively
precluded from pursuing remedies under the US securities laws in the US courts.

A  holder of  our  common  shares  and  ADSs  might be  unable  to  exercise  preemptive  rights  and  tag-along  rights
with respect to the common shares.

U.S. holders of common shares and ADSs may not be able to exercise the preemptive  rights  and  tag-along  rights
relating  to  common  shares  unless  a  registration  statement  under  the  U.S.  Securities  Act  of  1933  is  effective  with
respect to those rights or an exemption from the registration requirements of the Securities Act is available.  We are
not  obligated  to  file  a  registration  statement  with  respect  to  our  common  shares  relating  to  these  rights,  and  we
cannot  assure  you  that  we  will  file  any  such  registration  statement.    Unless  we  file  a  registration  statement  or  an
exemption  from  registration  is  available,  a  holder  may  receive  only  the  net  proceeds  from  the  sale  of  his  or  her
preemptive rights and tag-along rights or, if these rights cannot be sold, they will lapse and the holder will receive
no value for them.

A holder of our ADSs may find it more difficult than a holder of our common shares to exercise his or her voting
rights at our shareholders’ meetings.

Holders may exercise voting rights with respect to the common shares represented by our ADSs only in accordance
with the deposit agreement relating to our ADSs.  There are no provisions under Brazilian law or under our by-laws
that limit the exercise by ADS holders of their voting rights through the depositary with respect to the underlying
common shares.  However, there are practical limitations upon the ability of ADS holders to exercise their voting
rights  due  to  the  additional  procedural  steps  involved  in  communicating  with  these  holders.    For  example,  our
common  shareholders  will  receive  notice  of  shareholders’  meetings  through  publication  of  a  notice  in  an  official
government publication in Brazil and will be able to exercise their voting rights by either attending the meeting in

19

person  or  voting  by  proxy.    ADS  holders,  by  comparison,  will  not  receive  notice  directly  from  us.    Instead,  in
accordance with the deposit agreement, we will provide the notice to the depositary, which will, in turn, as soon as
practicable thereafter mail to holders of ADSs the notice of the meeting and a statement as to the manner in which
instructions may be given by holders, but only if we request the depositary to do so.  To exercise their voting rights,
ADS holders must then instruct the depositary as to voting the common shares represented by their ADSs.  Due to
these procedural steps involving the depositary, the process for exercising voting rights may  take  longer  for ADS
holders  than  for  holders  of  common  shares.    ADSs  for  which  the  depositary  fails  to  receive  timely  voting
instructions will not be voted at any meeting.

Developments in other emerging market countries may adversely affect the Brazilian economy and, therefore, the
market prices of our common shares and ADSs, as well as of our debt securities.

In  the  past,  the  Brazilian  economy  and  the  securities  of  Brazilian  companies  have  been,  to  varying  degrees,
influenced by economic and market conditions in other emerging market countries as well as investors’ responses to
those conditions.

In  addition,  although  economic  conditions  are  different  in  each  country,  investors’  reactions  to  adverse
developments in one country may affect the market price of securities of issuers in other countries, including Brazil.
For example, the 1997 Asian economic crisis and the 1998 Russian debt moratorium and devaluation of the Russian
currency and the  recent  economic  crises  in Argentina  and Venezuela  triggered  market  volatility  in  Latin  America
and securities markets in other emerging market countries.  Accordingly, adverse developments in other emerging
market countries could lead to a reduction in the demand for, and market prices of, our common shares and ADSs,
as well as our debt securities.

Changes in Brazilian tax laws may have an adverse impact on the taxes applicable to a disposition of the ADSs.

According to Law No. 10,833, enacted on December 29, 2003, the disposition of assets located in Brazil by a non-
resident  to  either  a  Brazilian  resident  or  a  non-resident  is  subject  to  taxation  in  Brazil,  regardless  of  whether  the
disposition  occurs  outside  or  within  Brazil.  In  the  event  that  the  disposition  of  assets  is  interpreted  to  include  a
disposition of the ADSs, this tax law could result in the imposition of withholding taxes on a disposition of ADSs by
a  non-resident  of  Brazil  to  another  non-resident  of  Brazil.  Due  to  the  fact  that  no  judicial  guidance  as  to  Law
10,833’s  application  yet  exists,  we  are  unable  to  predict  whether  an  interpretation  applying  such  tax  laws  to
dispositions of ADSs between non-residents could ultimately prevail in the courts of Brazil.

INFORMATION ON THE COMPANY

General

Companhia  de  Saneamento  Básico  do  Estado  de  São  Paulo-SABESP  is  a  sociedade  de  economia  mista,  a  mixed
capital  company  with  limited  liability  of  unlimited  duration,  duly  organized  and  operating  under  Brazilian
corporation law.  Our principal executive offices are located at Rua Costa Carvalho, 300, 05429-900 São Paulo, SP,
Brazil.  Our telephone number is (55-11 3388-8000).  Our agent for service of process in the United States is CT
Corporation System, with offices at 111 Eighth Avenue, New York, New York 10011.  As set forth in Article 2 of
our by-laws, our corporate purpose is to plan, execute, and operate basic sanitation services throughout the territory
of  the  state  of  São  Paulo,  including  the  capture,  collection,  processing  and  distribution  of  water,  as  well  as  the
collection, removal, processing and final disposal of sewage and sludge.

We  believe  we  are  one  of  the  largest  water  and  sewage  company  in  Latin  America  based  on  net  revenue  and
customers in 2004.  We operate water and sewage systems in the state of São Paulo in which the City of São Paulo,
Brazil’s largest city, is located.  According to the Brazilian Institute of Geography and Statistics, or IBGE, the state
of São Paulo is Brazil’s most populous state and the state with the highest GDP in Brazil.  We had net revenue from
income  of  R$513.0 million
sales  and  services  of  R$4,397.1 million 
(U.S.$193.3 million) for 2004.  We had total assets of R$16,783.8 million (U.S.$6,323.0 million) and shareholders’
equity of R$7,951.6 million (U.S.$2,995.6 million) as of December 31, 2004.

(U.S.$1,656.5 million)  and  net 

We  provide  water  and  sewage  services  to  a  broad  range  of  residential,  commercial,  industrial  and  governmental
customers  in  368  of  the  645  municipalities  in  the  state  of  São  Paulo,  including  the  City  of  São  Paulo.    We  also
supply water on a wholesale basis to six municipalities in the São Paulo Metropolitan Region in which we do not
operate water systems.  Until December 2002 we divided our service territories into three regions:  the São Paulo
Metropolitan  Region,  the  Interior  Region  and  the  Coastal  Region.    During  2003  we  reorganized  our  corporate
management structure by consolidating the municipalities which we serve in the interior and coastal regions into a
single management unit we call “Regional Systems.”  Under this new structure, the São Paulo Metropolitan Region
and  the  Regional  Systems  accounted  for  74.5%  and 25.5% of our  gross revenue from  sales  and  services  in  2004,
respectively.

As  of  December  31,  2004,  we  distributed  water  to  approximately  22.3 million  people,  which  we  believe  includes
approximately 60% of the urban population of the state of São Paulo, through approximately 58,073 kilometers of
water pipes and mains to more than 6.4 million water connections.  As of December 31, 2004, we provided sewage
services to approximately 18.2 million people through 36,435 kilometers of sewer lines to approximately 4.7 million
sewage  connections.    In  addition,  we  currently  sell  water  on  a  wholesale  basis  to  six  municipalities  having  an
estimated population of approximately 3.1 million in the aggregate.

The State, our controlling shareholder, is required by our by-laws and State law to own at least one-half plus one of
our  common  (voting)  shares.    The  State  currently  owns  50.3%  of  our  outstanding  common  shares.    As  a  mixed
capital company, we are an integral part of the governmental structure of the State.  Our strategy and major policy
decisions are formulated in conjunction with the Energy, Water Resources and Sanitation Secretariat of the State as
part of the overall strategic planning for the State.  The majority of the members of our Board of Directors and our
Executive Committee are nominated by the State Council for Protection of Capital of the State (Conselho de Defesa
de Capitais do Estado de São Paulo—CODEC), a State agency presided over by the Secretary of the State Treasury
and reporting directly to the Governor.

In addition, our capital expenditure budget is subject to approval by the legislature of the State and is approved in
conjunction with the budget of the Energy, Water Resources and Sanitation Secretariat and of the state of São Paulo
as a whole.  Our financial statements and accounting records are subject to review by the State Accounts Tribunal
(Tribunal de Contas), as are all accounts of the State.

State of São Paulo

The state of São Paulo is one of 26 states that, together with the Federal District of Brasilia, constitute the Federative
Republic of Brazil.  The state of São Paulo is located in the southeastern region of the country, which is, according
to  IBGE,  the  most  developed  and  economically  active  region  of  Brazil,  and  which  includes  the  states  of  Minas
Gerais,  Espírito  Santo  and  Rio  de  Janeiro.    The  state  of  São  Paulo  lies  between  the  states  of  Rio  de  Janeiro  and
Minas Gerais to the north, the state of Paraná to the south, Mato Grosso do Sul to the west and the Atlantic Ocean to
the east.

The state of São Paulo occupies 3.0% of Brazil’s land mass and encompasses an area totaling approximately 96,000
square  miles.    According  to  the  State  of  São  Paulo  Data  System  (Fundação  Sistema  Estadual  de  Análises  de
Dados—SEADE), the state of São Paulo had an estimated population as of December 31, 2004 of 39.6 million.

As of December 31, 2004, the City of São Paulo, the state of São Paulo’s capital, had an estimated population of
10.7 million,  with  19.0 million  inhabitants  in  the  greater  São  Paulo  Metropolitan  Region.    The  São Paulo
Metropolitan Region encompasses 39 cities and is the second largest metropolitan area in the Americas and among
the  four  largest  metropolitan  areas  in  the  world,  according  to  the  United  Nations’  World  Urbanization  Prospects,
1999 Revision.  The São Paulo Metropolitan Region accounted for approximately 48% of the population of the state
of São Paulo as of December 31, 2004.

According to IBGE, in 2002, the most recent year for which this data is available, the GDP of the state of São Paulo
was  approximately  R$438.1 billion,  representing  approximately  32%  of  Brazil’s  total  GDP,  making  it  the  largest
economy  of  any  state  in  Brazil,  based  on  GDP.    The  state  of  São  Paulo  is  the  leading  Brazilian  state  in  terms  of
manufacturing  and  industrial  activity,  also  according  to  IBGE,  with  a  strong  position  in  car  manufacturing,
pharmaceuticals, computer production, steel making and plastics, among others, as well as the leading position  in
the banking and financial services industries.  The state of São Paulo is the most important exporting state in Brazil,
according to the Brazilian Ministry of Development, Industry and Foreign Trade (Ministério do Desenvolvimento,
Indústria e Comércio Exterior).

History

Until the end of the 19th century, water and sewage services in the state of São Paulo were generally provided by
private companies.  In 1877, the Province of São Paulo granted a concession for the provision of water and sewage
services  to  Companhia  Cantareira  de  Água  e  Esgotos.    In  1893,  the  Government  of  the  Province  of  São  Paulo
assumed responsibility for the provision of water and sewage services from the Companhia Cantareira de Água e
Esgotos and formed the Office of Water and Sewers (Repartição de Água e Esgotos), a governmental agency.  Since
that  time,  water  and  sewage  services  in  the  São  Paulo  Metropolitan  Region  have  been  administered  by  the
government of the State.  Historically, water and sewage services in substantially all other municipalities of the State
were  administered  by  the  municipalities  directly  either  by  municipal  water  and  sewage  departments  or  through
autarquias of  the  municipal government.    Autarquias  are  relatively  autonomous public bodies  with  separate  legal
standing, assets and revenues, created by law to undertake administration of public services, which are considered to
be better managed by a decentralized administrative and financial structure.

In 1954, in response to dramatic population growth in the São Paulo Metropolitan Region, the government of the
State created the Department of Water and Sewers (Departamento de Águas e Esgotos), as an autarquia of the State.
The Department of Water and Sewers provided water and sewage services to various municipalities in the São Paulo
Metropolitan Region.

A major restructuring of the entities providing water and sewage services in the state of São Paulo occurred in 1968
with  the  creation  of  the  Companhia  Metropolitana  de  Água  de  São  Paulo,  or  COMASP,  whose  purpose  was  to
provide potable water wholesale for public consumption in the municipalities making up the São Paulo Metropolitan
Region.    All  assets  relating  to  the  production  of  potable  water  for  the  São  Paulo  Metropolitan  Region  previously
owned by the Department of Water and Sewers were transferred to  COMASP.  In 1970,  the Superintendência  de
Água  e  Esgoto  da  Capital,  or  SAEC,  was  created  by  the  government  of  the  State  to  distribute  water  and  collect
sewage in the City of São Paulo.  All assets previously owned by the Department of Water and Sewers in connection

22

with  such  activities  were  transferred  to  SAEC.    Also  in  1970,  the  State  created  the  Companhia  Metropolitana  de
Saneamento  de  São  Paulo,  or  SANESP,  to  provide  sewage  treatment  services  for  the  São  Paulo  Metropolitan
Region.    All  assets  previously  owned  by  the  Department  of  Water  and  Sewers  in  connection  with  such  activities
were transferred to SANESP.  The Department of Water and Sewers was subsequently closed.

On June 29, 1973, COMASP, SAEC and SANESP merged to form our company with the purpose of implementing
the  directives  of  the  Brazilian  government  set  forth  in  the  National  Water  Supply  and  Sanitation  Plan  (Plano
Nacional  de  Saneamento).    The  National  Water  Supply  and  Sanitation  Plan  was  a  program  sponsored  by  the
Brazilian  government,  which  financed  capital  investments  in,  and  assisted  in  the  development  of,  state-controlled
water  and  sewage  companies.    Since  our  formation,  other  State  governmental  and  State-controlled  companies
involved in water supply and sewage collection and treatment in the state of São Paulo have been merged into us.

Recovery Program

We  experienced  significant  operational  and  financial  problems  beginning  in  the  mid-1980’s,  which  culminated  in
1994.  These problems were due, in part, to adverse economic conditions in Brazil prior to implementation of the
Real  Plan  in  mid-1994,  but  also  to  our  position  as  a  State-controlled  enterprise  whose  financial  performance  was
then only a secondary consideration of the State.

We also had significant and increasing levels of unpaid accounts receivables from our customers, including the State
and municipal governments.

In 1995, we, in conjunction with the administration of the State, initiated a “recovery” program designed to restore
our business operations and financial condition, including the organizational restructuring, the implementation of the
initial stages of our strategy and the development of a new “for-profit” orientation.

We believe that our continuing recovery program and the continuing implementation of our overall strategy have, to
date,  permitted  a  recovery  in  terms  of  our  business  operations  and  financial  performance,  which  we  expect  to
provide the basis for our long-term operational and financial development.

Strategy

Our mission is to improve the quality of life of the population of the state of São Paulo and, in particular, to meet the
growing  demand  for  water  and  sewage  services  in  an  environmentally  responsible  manner.    We  are  seeking  to
expand and improve our operations so that we can fulfill our mission and at the same time strengthen our financial
condition.

Our overall strategy is based upon three guiding principles:

•

•

•

Marketing  Strategy:    to  expand  our  water  and  sewage  services  in  our  existing  service  areas,  to
maintain  our  existing  concession  base  and  to  obtain  additional  concessions  and  operations  in
additional municipalities in the state of São Paulo;

Economic/Financial Strategy:  to enhance our financial condition, our “for-profit” orientation and
shareholder  value  by,  among  other  things,  ensuring  proper  remuneration  for  our  services,
increasing  productivity,  improving  operating  efficiencies  and  diversifying  sources  of  financing;
and

Political/Institutional Strategy:  to develop closer relationships with municipal governments and
with customers by means of decentralized business units and increased participation in decisions
affecting municipalities.

These three guiding principles are broken down into the following key strategic initiatives:

23

•

•

•

•

•

Continue to Expand Our Water and Sewage Services in Our Existing Service Area.  Our goal is to
maintain universal coverage of water services and to increase penetration of sewage collection and
treatment services in our existing service areas of operation.  A significant portion of our capital
expenditure  program,  which  will  require  total  expenditures  of  approximately  R$4.2  billion
between 2005 and 2009, is designed to achieve this goal.  We aim to continue providing universal
water coverage and meet population growth by adding 810,000 water connections by 2009.  We
also intend to increase our sewage coverage ratio to 85% by adding 810,000 sewage connections
by 2009.

Maintain  our  Existing  Concession  Base  and  Obtain  Additional  Municipal  Concessions  and
Operations.    Our  goal  is  to  renew  all  of  our  existing  concessions  as  they  expire.    We  have
assembled a special task force to address concession expiration in a timely and effective manner.
In addition to this ongoing effort, we regularly explore the possibility of obtaining additional water
and sewage concessions in municipalities in the state of São Paulo in which we currently have no
operations or to which we currently supply water solely on a wholesale basis.  This represents a
total population of approximately 15.1 million.  We evaluate possible expansion opportunities in
terms  of  proximity  to  our  existing  service  areas  and  projected  positive  contributions  to  our
financial  performance.    Since  January  1,  1997,  we  have  obtained  34  additional  concessions  to
provide water and sewage services in municipalities in the state of São Paulo (representing a total
population  of  1.4 million),  including  the  municipalities  of  Osasco,  which  previously  was  one  of
our  wholesale  sales  customers,  and  Itapira,  which  we  acquired  in  March  2004.    Another
achievement  in  this  effort  was  the  December  2003  acquisition  of  the  right  to  operate  water  and
sewage services in the Municipality of São Bernardo do Campo through the transfer of all related
assets  from  the  municipality  to  us.    Until  then,  we  provided  water  to  that  municipality  on  a
wholesale basis.  This acquisition positively impacted our business and our financial condition in
2004.

Set Our Tariffs to Cover Our Costs of Operations and to Provide a Return on Investment.  Current
tariff regulations allow us to set tariffs more aggressively and to tailor them to the peculiarities of
each service, the diversity of the  regions  covered  and  the  social  and  economic  conditions  of  the
end  user.    We  periodically  adjust  our  tariffs  for  water  and  sewage  services  using  a  transparent
formula which accounts for inflation, covers our operating costs and other expenses and provides
for  return  on  investment.    We  generally  adjust  our  tariffs  once  a  year  for  a  period  of  at  least
12 months.  In 2004, we increased our tariffs by approximately 6.8%, effective as of August 29,
2005.

Continue to Reduce Operating Costs and to Increase Productivity.  We are continuing our efforts
to lower operating costs and to increase productivity.  In order to achieve this, we plan to reduce
our  total  salary  and  payroll  expenses  by  decreasing  the  number  of  our  employees,  outsourcing
more of our non-core activities and automating some of our operations.  We have in the past and
expect in the future to reduce our number of employees through voluntary resignation and early
retirement  programs.    We  are  continuing  our  efforts  to  automate  and  outsource  our  operations,
especially in the interior region of the state of São Paulo, where introduction of new technology is
expected to improve both operating efficiency and safety.  We are also continuing our efforts to
outsource  meter  reading  and  maintenance  services  in  the  Regional  Systems,  as  we  have
successfully done in the São Paulo Metropolitan Region.  In 2004, we reduced our total number of
employees by 4.4%.  Water and sewage connections per employee increased from 566 to 626 in
the same period.

Improve Operating Efficiency and Reduce Water Losses.  We seek to reduce both physical water
losses  (due  primarily  to  leakage  from  our  water  system)  and  non-physical  water  losses  (due  to
meter  errors  that  prevent  proper  accounting  of  water  use,  improper  classification  of  customers,
fraud  and  illegal  connections).    We  are  continuing  our  efforts  to  reduce  physical  water  losses
through,  among  other  things,  the  replacement  and  repairing  of  water  mains  and  pipes  and
installation  of  probing  and  other  equipment.    We  are  continuing  our  program  of  strategically

24

locating pressure-regulating valves throughout our water system, which regulate water pressure at
a variable rate corresponding to consumption in the relevant sector.  We are also striving to reduce
physical water losses by continuing to shorten the average time to detect and repair leaks in our
systems.  We aim to reduce water losses in the São Paulo Metropolitan Region and in the Regional
Systems, from 34.9% and 31.4% respectively, in 2004 to 26% in both regions by 2009.  We are
aiming  to  reduce  non-physical  water  losses  by  upgrading  and  replacing  inaccurate  water  meters
and through increased outsourcing of meter reading activities to third-party contractors outside the
São Paulo Metropolitan Region.  In particular, we are replacing the water meters for our industrial
and  commercial  customers,  as  well  as  increasing  the  rate  at  which  we  read  the  meters  for  these
customers, to minimize losses.

Improve  Collection of  Overdue  Accounts  Receivable.   We  are  continuing  our  efforts  to  improve
our collection of overdue accounts receivable from municipalities to which we provide water on a
wholesale basis, from the State and from other governmental entities.  We are actively pursuing
the amounts overdue and in some cases exploring opportunities to swap the amounts overdue in
exchange  for  the  rights  and  infrastructure  to  operate  the  water  and  sewage  systems  of  certain
municipalities.    For  example,  we  recently  acquired  the  right  to  operate  the  water  and  sewage
services in the Municipality of São Bernardo do Campo through the transfer of all related assets
from the municipality to us in partial exchange for overdue accounts receivable.

Diversify Sources of Financing.  Our goal is to continue to identify and secure diverse sources of
financing, both public and private, with an emphasis on borrowing in local currency to reduce our
exposure to exchange rate fluctuations and on borrowing long-term funds to match the duration of
our  long-term  assets.    Currently,  we  are  negotiating  with  the  BNDES  and  Caixa  Econômica
Federal (a bank owned by the Brazilian government) with a view to obtaining loans to finance our
capital  expenditure  program.    We  are  also  exploring  and  pursuing  various  structured  finance
alternatives.

Maintain Close Relationships with Municipal Governments and with Customers.  We are seeking
to develop closer relationships with the municipal governments and with customers that we serve.
We  meet  regularly  with  the  mayors  of  municipalities  and  organize  regional  management
commissions  comprised  of  mayoral  representatives  and  of  our  officers  to  discuss  water  and
sewage  services,  capital  expenditures,  tariffs  and other  issues.    We  are  also  working  to  improve
customer  relations  by  shortening  response  times  for  customer  installations  as  well  as  through  a
focused public relations program to enhance our image.

•

•

•

We believe that our overall strategy will enable us to meet the demand for high quality water and sewage services in
the  state  of  São  Paulo  and,  at  the  same  time,  bolster  our  results  of  operations  and  our  financial  condition  and
enhance shareholder value.

Corporate Organization

During 2004, we reorganized our corporate management structure.  As a result, we currently have six management
divisions, each of which is supervised by one of our executive officers.

The  allocation  of  responsibilities  among  the  executive  officers  is  made  by  the  Board  of  Directors,  in  accordance
with the by-laws and following receipt of an initial proposal from the Chief Executive Officer.

•

Chief  Executive  Office  —  responsible  for  coordinating  all  management  divisions  in  accordance
with the policies and directives established by our Board of Directors and Executive Committee,
performing the coordination, evaluation and control of all functions related to the Chief Executive
Officer’s  Office,  strategic  planning,  corporate  organization,  corporate  communication,  audit  and
ombudsman.

25

•

•

•

•

•

Corporate Management Office — responsible for marketing, human resources and quality control
programs, legal affairs, information technology, asset management, contracts and procurement.

Economic  and  Financial  and  Investor  Relations  Office  —  responsible  for  financial  planning,
raising  and  allocating  financial  resources  to  all  divisions  within  the  company,  conduct  capital
markets  and  other  debt  transactions  and  manage  debt  levels,  accounting  and  investor  relations.
This division also monitors and acts as controller for our other divisions.

Planning and Technology Office — responsible for integrated  technical  planning,  environmental
planning and management, technological development, management and control of water quality,
strategic  maintenance,  integrated  project  management  and  coordination  and  execution  of  special
projects.

São Paulo Metropolitan Region Office — responsible for the distribution of water and collection
of sewage for the São Paulo Metropolitan Region.  The main function of this division is planning,
operating and maintaining the water and sewage systems and customer relation services in the São
Paulo  Metropolitan  Region  and  wholesale  water  supply  and  sewage  treatment,  as  well  as
providing technical support for the autonomous municipalities.

Regional  Systems  Division  —  responsible  for  the  production  of  water  and  operation  and
maintenance  of  water  and  sewage  systems  in  municipalities  in  the  Regional  Systems.    It  is  also
responsible for performing the same tasks as the Metropolitan Division.

Each business unit providing water and sewage services to customers participates in a regional assembly consisting
of  the  mayors  of  the  municipalities  covered  by  such  unit  and  our  officers.    In  addition,  for  each  unit,  a  regional
management commission comprised of five to eight mayors and five to eight of our officers has been established to
facilitate discussions and decision-making over such issues as the unit’s budget, capital expenditure program, tariffs,
and water and sewage services generally.

As a result of the establishment of the regional management commissions, we believe that we have improved our
relationships with the municipalities and with our customers generally and that we have been able to balance better
the  service  requirements  of  our  customers  with  our  own  operational  and  financial  objectives.    The  increased
interaction  between  us  and  the  municipalities  has  also  been  responsible  for  renewed  indications  of  interest  in  our
water and sewage services on the part of those municipalities not currently being served by us.

Concessions

Under the Brazilian Constitution, the authority to develop public water and sewage systems is shared by the states
and municipalities, with the municipalities having primary responsibility for providing water and sewage services to
their residents.  The State Constitution provides that the State shall assure the correct operation, necessary expansion
and efficient administration of water and sewage services in the state of São Paulo by a company under its control.
Under  applicable  law,  we  are  responsible  for  planning  basic  water  and  sewage  services  and  operating  the  related
systems  in  the  state  of  São  Paulo,  whilst  respecting  the  autonomy  of  its  municipalities.    The  municipalities  are
empowered  to,  and  commonly  do,  grant  long-term  concessions  to  water  and  sewage  companies  to  provide  such
services.

We do not hold a formal concession to provide water and sewage services in the City of São Paulo, which accounts
for  56.1%  of  our  revenue,  and  in  40  other  municipalities  in  the  state  of  São  Paulo.    None  of  these  other
municipalities  has  a  significant  population,  other  than  Santos,  which  has  a  population  exceeding  400,000.    We
believe  that  we  have  a  vested  right  to  provide  water  and  sewage  services  based  upon,  among  other  things,  our
ownership of the water and sewage systems serving the City of São Paulo and these other municipalities and certain
succession  rights  resulting  from  the  merger  which  formed  us.    In  general,  we  do  not  face  any  competition  in  the
municipalities in which we provide water and sewage services, and we believe that in those municipalities we have
an exclusive right to provide such services.  Private water companies currently provide water and sewage services to
only three municipalities in the state of São Paulo.

26

We  also  provide  water  and  sewage  services  in  326  additional  municipalities  in  the  State  pursuant  to  concessions
granted  by  the  municipalities.    Substantially  all  of  these  concessions  have  30-year  terms,  273  of  which  expire
between 2005 and 2010, of which 17 and 127 are scheduled to expire in 2005 and 2006; and the rest of which expire
between 2011 and 2034.  The Botucatu concession expired on September 18, 2004.  The municipality of Botucatu
issued a Municipal Decree on October 19, 2004 extending our concession for an additional 12 months and we are in
discussions to renew this concession for 30 years.  A majority of these concessions are automatically renewable for a
period equal to its initial term, although we often renegotiate terms and  conditions, unless  the  municipality  or we
exercise  the  right  to  terminate  the  concession  prior  to  the  six-month  period  ending  on  the  expiration  date  of  the
concession.

The concessions are based on a standard form of contract between us and the relevant municipality.  Each contract
must receive the prior approval of the legislative council of the relevant municipality.  The principal terms of the
concession contracts are as follows:

•

•

•

•

•

•

We assume all responsibility for providing water and sewage services in the municipality.

We  may  determine  and  collect  the  tariffs  for  our  services  without  prior  authorization  of  the
municipality.

The assets comprising the existing municipal water and sewage systems are transferred from the
municipality  to  us.    Until  1998,  we  acquired  municipal  concessions  and  the  existing  water  and
sewage  assets  in  exchange  for  our  common  shares  issued  at  book  value.    Since  1998,  we  have
acquired concessions and water and sewage assets by paying the municipality an amount equal to
the present value of 30 years of estimated cash-flows, assuming at least a 12.0% discount factor to
us, from the concession being acquired.  Payment is made in cash.

We are exempt from municipal taxes, and no royalty is payable to the municipality with respect to
the concession.

We are granted rights of way on municipal property for the installation of water pipes and mains
and sewage lines.

On termination of the concession, or upon cancellation for any reason, we are required to return
the  assets  comprising  the  municipality’s  water  and  sewage  system  to  the  municipality  and  the
municipality  is  required  to  pay  us  the  non-amortized  book  value  of  our  assets  relating  to  such
concession.

Under concession contracts executed prior to 1998 we were reimbursed for these assets through payment of either:

•

•

the book value of the assets; or

the  market  value  of  the  assets  as  determined  by  a  third-party  appraiser  in  accordance  with  the
terms of the specific contract.

Concession  contracts  we  have  entered  into  since  1998  provide  that  after  a  period  of  30  years  from  the
commencement  of  the  concession,  the  total  value  of  the  concession  and  assets  will  be  amortized  to  zero  on  our
books  and  we  receive  no  payment  for  the  assets.    If  the  concession  is  terminated  prior  to  the  end  of  the  30-year
period,  we  are  paid  an  amount  equal  to  the  present  value  of  the  cash-flow  from  the  concession  over  the  years
remaining in the concession, using the same assumptions as were used to determine the value of the concession at its
inception (adjusted for inflation).

Municipalities  have  the  inherent  power  under  Brazilian  law  to  terminate  concessions  prior  to  their  contractual
expiration  dates  for  reasons  of  public  interest.    Diadema  and  Mauá,  two  municipalities  we  previously  served,
terminated our concessions in February 1995 and December 1995, respectively.  Diadema terminated our concession

27

after  asserting  that we  did  not  provide  adequate  water  and  sewage  services,  while  Mauá  did  so  with  our  consent.
However, we currently serve both Diadema and Mauá through the sale of water on a wholesale basis.

We  currently  do  not  anticipate  that  other  municipalities  will  seek  to  terminate  concessions  due  to,  among  other
factors, our development of closer relationships with municipal governments, recent improvements in the water and
sewage services we provide and the obligation of  the  municipality  to  repay  us  for  the  return of  the  concession  as
described  above.    We  cannot  be  certain,  however,  that  other  municipalities  will  not  seek  to  terminate  their
concessions in the future.

In addition to our concessions, in December 2003, we acquired water and sewage service assets in the Municipality
of  São  Bernardo do  Campo  through  the  transfer  of  all  related  assets  from  the  municipality  to  us.    Previously,  we
provided water to São Bernardo do Campo on a wholesale basis.  The amount paid for the purchase of assets was
estimated by an economic-financial valuation report, which included the liquidation of the water wholesale supply
accumulated debt.  See “Item 5.  Operating and Financial Review and Prospects—Liquidity and Capital Resources”
for information with respect to the São Bernardo do Campo transaction.

Description of Our Activities

We provide basic sanitation services, which include the abstraction, treatment, processing and distribution of water,
as well as the collection, treatment and reuse of sewage.  We believe we are the largest water and sewage service
provider company in Latin America, based on net revenue and customers in 2004.  We render our services in the
state of São Paulo, where the City of São Paulo, the largest city in Brazil, is located.

Water Operations

Our  supply  of  water  to  our  customers  generally  involves  abstraction  of  water  from  various  sources,  subsequent
treatment  and  distribution  to  customers’  premises.    In  2004,  we  produced  approximately  2,770.5 million  cubic
meters  of  water.    The  São  Paulo  Metropolitan  Region  currently  is,  and  has  historically  been,  our  core  market,
accounting for approximately 71.3% of water invoices in volume.

The following table sets forth the amount of water produced and invoiced by Sabesp for the periods stated.

The difference between the amount of water produced and the amount of water invoiced generally represents both
physical and non-physical water loss.  See “—Water Distribution” below.  In addition, we do not invoice:

•

•

•

•

water discharged for periodic maintenance of water mains and water storage tanks;

water supplied for municipal uses such as firefighting;

water consumed in our own facilities; and

estimated water losses associated with water we supply to favelas (shantytowns).

The São Paulo Metropolitan Region experiences its highest levels of demand during the summer months when water
use  increases.    Water  use  generally  decreases  during  the  winter  months.    The  summer  months,  when  demand  is
highest, coincide with the rainy season, while the winter, when demand for water is lowest, corresponds to the dry
season  in  the  São  Paulo  Metropolitan  Region.    Demand  within  the  Regional  Systems  will  vary  depending  on  the
area; while the interior region experiences seasonality in demand similar to the São Paulo Metropolitan Region, the
demand  in  the  coastal  region  is  chiefly  a  function  of  tourism,  with  the  greatest  demand  occurring  during  the
Brazilian summer holiday months.

We can abstract water only to the extent permitted by the Department of Water and Energy of the State and pursuant
to authorization contracts executed with it.  Under some circumstances, depending on the geographic location of the
relevant river basin or reservoir, the approval of the National Water Agency is also required.  We currently abstract
substantially  all  of  our  water  supply  from  rivers  and  reservoirs,  with  a  small  portion  being  abstracted  from
groundwater.  Our reservoirs are filled by impounding water from rivers and streams, by diverting flow from nearby
rivers, or by a combination of these sources.

In order to supply water to the São Paulo Metropolitan Region, we rely on 17 reservoirs of non-treated water and
135  reservoirs  of  treated  water,  which  are  located  in  the  areas  under  the  influence  of  the  eight  water  producing
systems which comprise the integrated water system of the São Paulo Metropolitan Region.  Resource availability,
or amount of water available at the source for public distribution in such areas, is 66.1 cubic meters per second and
should  increase  to  72.0  cubic  meters  per  second  in  2006,  when  the  planned  extension  and  improvement  in  water
sources will be concluded.  Total current capacity, or amount of water that can be treated from the integrated water
system of the São Paulo Metropolitan Region, is 67.7 cubic meters per second and has been designed to reach 70.2
cubic meters per second in 2006.  Average verified production or amount treated during 2004 was 63.3 cubic meters
per second.  The Cantareira, Guarapiranga and Alto Tietê systems, as a whole, supply approximately 83.6% of the
water we produced for the São Paulo Metropolitan Region.

The Cantareira system accounts for approximately 47.1% of the water that we provide to the São Paulo Metropolitan
Region, which represented 74.5% of our operating revenue for 2004.  The authorization (outorga) for the Cantareira
system to use the water in the Piracicaba water basin was renewed by Portaria DAEE n° 1213 on August 6, 2004 for
a period of ten years.

We own all of the reservoirs in our production systems other than the Guarapiranga and Billings reservoirs and a
portion of some of the reservoirs of the Alto Tietê System, which is owned by other companies controlled by the
State.  We currently do not pay any fees with respect to the use of these reservoirs.  In December 2001, we entered
into an agreement with the State whereby the State, among other things, agreed to transfer the remaining reservoirs
in the Alto Tietê System to us.  However, the transfer of these reservoirs is currently being disputed and we are not
certain whether such transfer will be legally allowed.  See “Item 8.  Financial Information— Legal Proceedings—
Other Legal Proceedings.”

In  the  largest  municipalities  of  the  interior  region,  our  principal  source  of  water  consists  of  surface  water  from
nearby rivers.  In the smaller municipalities of the interior region, we draw water primarily from wells.  The coastal
region is provided water principally by surface water from rivers and mountain springs.

Statewide, we estimate that we are able to supply nearly all of the demand for water in all of the areas where we
operate, subject to droughts and extraordinary climate events.  In 2002, 2003 and 2004, we were able to meet the
demand for water in the São Paulo Metropolitan Region, primarily as a result of our water conservation program,
reductions  in  water  loss,  the  installation  of  905,600  new  water  connections  from  2000  through  December 2004
statewide,  as  well  as  the  introduction  of  a  new  tariff  structure  which  helped  reduce  average  consumption  and
demand.

Water  in  the  São  Paulo  Metropolitan  Region  is  distributed  through  the  Metropolitan  Aqueduct  System.    The
Metropolitan Aqueduct System is a network of aqueducts that covers most of the São Paulo Metropolitan Region,
which allows for diversion of water from or to a particular region as demand varies, as required to properly supply a
particular area of the network.

We are implementing as part of our capital expenditure program the Metropolitan Water Program, which involves
substantial investments in reservoirs, water treatment facilities, water mains and the distribution network in the São
Paulo  Metropolitan  Region  to  increase  water  production  and  to  improve  capacity  of  the  Metropolitan  Aqueduct
System.    The  Metropolitan  Water  Program  consists  of  a  series  of  projects  which  will  require  approximately
R$661 million in investments from 2005 through 2009 in the São Paulo Metropolitan Region.

Water Treatment.  We treat all water at our water treatment facilities prior to placing it into our water distribution
network.    We  operate  195  treatment  facilities,  of  which  the  eight  largest,  located  in  the  São  Paulo  Metropolitan
Region, typically account for approximately 74% of all water we supply.  The type of treatment used depends on the
nature of the source and quality of the untreated water.  Water abstracted from rivers requires extensive treatment,
while water drawn from groundwater sources requires less treatment.

30

We use conventional treatment processes in our water treatment facilities.  For surface water, the treatment process
involves several phases, including filtration and disinfection.  Groundwater typically is of higher purity and usually
requires only disinfection by chlorine treatment.  All water we treat also receives fluoridation treatment.

Water  Distribution.    We  distribute  through  our  own  networks  of  water  pipes  and  mains,  ranging  in  size  from
2.5 meters  to  100  millimeters  in  diameter. 
  As  of  December 31,  2004,  our  water  network  contained
58,073 kilometers of water pipes and mains and 6.4 million water connections.  The following table sets forth the
total number of kilometers of water pipes in our network for the periods indicated.

Approximately  95.0%  of  the  water  pipes  in  our  water  distribution  network  are  made  of  cast  iron  or
polyvinylchloride  (PVC).    Distribution  pipes  at  customers’  residences  typically  are  made  from  high-density
polyethylene tubing.  Our water mains are mostly made of steel, cast iron or concrete.

We distribute treated water through our networks of mains and service pipes that deliver water through pressurized
systems.  Storage tanks and pumping stations regulate the volume of water flowing through the networks to maintain
adequate pressure and continuous water supply.

As of December 31, 2004, our water distribution pipes and mains included:

•

•

27,029 kilometers in the São Paulo Metropolitan Region; and

31,043 kilometers in the Regional Systems.

We have 313 storage tanks in the São Paulo Metropolitan Region with a total capacity of 1.8 million cubic meters,
and  1,657  storage  tanks  in  the  Regional  Systems.    We  have  192  treated  water  pumping  stations  in  the  São Paulo
Metropolitan  Region,  including  stations  at  treatment  facilities,  intermediate  trunk  transfer  pumping  stations  and
small booster stations serving local areas.

Water mains that require maintenance are cleaned and relined.  We are typically notified of water main fractures or
breaks by the public through a toll-free number maintained by us.  We consider the condition of the water pipes and
mains in the São Paulo Metropolitan Region generally to be adequate.  Due to age, external factors such as traffic,
the  high  population  and  commercial  and  industrial  development,  water  pipes  and  mains  in  the  São Paulo
Metropolitan  Region  are  somewhat  more  susceptible  to  degradation  than  those  in  the  Regional  Systems.    To
counteract these effects, we have a maintenance program in place for water pipes and mains that is intended to deal
with anticipated fractures and clogs due to brittleness and encrustation and to help ensure water quality.

We  expect  that  new  customers  will  be  responsible  for  covering  part  of  the  costs  of  connecting  to  our  water
distribution network.  Our water connection policy is to pay for the cost of installation of up to 15 meters of pipe
from our distribution network to the point of connection, with the remainder paid by the customer.  Thereafter, the
customer  must  cover  the  costs  of  connecting  to  the  network  from  the  customer’s  residence,  including  costs  of
purchasing and installing the water meter and related labor costs.  Industrial customers are responsible for the entire
cost  of  connection.    We  perform  the  installation  of  the  water  meter  and  conduct  periodical  inspections  and
measurements.    After  completion  of  installation,  the  customer  has  a  fiduciary  duty  to  the  network  and  the  water
meter.

Water Losses.  The difference between the amount of water produced and the amount of water invoiced generally
represents  both  physical  and  non-physical  water  losses.    Water  loss  percentage  represents  the  quotient  of  (a) the
difference between (i) the total amount of water produced by us (after excluding certain non-physical water losses
set  out  below)  less  (ii) the  total  amount  of  water  invoiced  by  us  to  customers  divided  by  (b) the  total  amount  of
water  produced  (after  excluding  certain  non-physical  water  losses  set  out  below)  by  us.    We  exclude  from  our
calculation of water losses the following:  (1) water discharged for periodic maintenance of water mains and water
storage tanks; (2) water supplied for municipal uses such as firefighting; (3) water we consume in our facilities; and
(4) estimated water losses associated with water we supply to favelas (shantytowns).

We  currently  experience  34.9%  water  losses  in  the  São  Paulo  Metropolitan  Region  and  31.4%  in  the  Regional
Systems.  We plan to reduce water losses in both regions to 26% by 2009.

Our strategy to reduce water loss has two main objectives:

•

•

first,  a  reduction  in  the  level  of  physical  losses,  which  result  primarily  from  leakage  primarily
through the replacement and repair of water mains and pipes and installation of probing and other
equipment, including strategically located pressure-regulating valves; and

second,  the  reduction  of  non-physical  losses,  which  result  primarily  from  the  inaccuracy  of  our
water meters installed at our customers’ premises and at our water treatment facilities, and from
clandestine and illegal use by customers, through upgrading and replacing inaccurate water meters
and by increasing outsourcing of meter reading activities to third-party contractors outside the São
Paulo Metropolitan Region.

We are taking measures to decrease physical losses by reducing response times to broken pipes and mains to less
than  24  hours  and  by  better  monitoring  of  non-visible  water  mains  fractures.    We  currently  repair  approximately
4,000 broken pipes and mains per month.  Among other measures we have adopted to reduce physical water losses
are:

•

•

•

the  introduction  of  technically  advanced  valves  to  regulate  water  pressure  throughout  the  water
mains  to  correspond  to  downstream  consumption  needs  during  each  day.    These  valves  are
programmed  to  respond  automatically  to  variations  in  demand.    During  peak  usage,  the  flow  of
water in the pipes is at its highest point; however, when demand decreases, pressure builds up in
the water mains and the resulting stress on the network can cause significant water loss through
cracks and an increase in ruptures of the pipes.  The intelligent valves are equipped with probes
programmed to feed data to the valve to reduce or increase pressure to the water mains as water
usage fluctuates.  As of December 31, 2004, we had installed 1,252 valves at strategic points in the
network, with 812 valves installed in the São Paulo Metropolitan Region and 440 in the Regional
Systems.  We plan to install additional 192 valves through 2005;

the  reconfiguration  of  integrated  water  distribution  to  permit  the  distribution  of  water  at  lower
pressure; and

routine  operational  leak  detection  surveys  in  high  water  pressure  areas  in  each  case  helping  to
reduce overall water losses.

32

Measures adopted to decrease non-physical water losses include:

•

•

•

•

monitoring  and  better  accounting  for  water  connections,  especially  for  large  volume  customers,
regular  checking  on  customers  which  are  accounted  for  by  us  as  inactive  and  monitoring  those
non-residential customers that are accounted for as residential and therefore are billed at a lower
rate;

measures to fight fraud and the use of new, more sophisticated water meters that are more accurate
and less prone to tampering;

installation of water meters where none are present; and

preventive maintenance of existing and newly installed water meters.

Water  Quality.    We  believe  that  we  supply  high  quality  treated  water  that  is  consistent  with  standards  set  by
Brazilian  Federal  Law,  as  well  as  the  standards  set  in  the  United  States  and  Europe.    Under  a  Health  Ministry
regulation in Brazil, we have significant statutory obligations regarding the quality of treated water.  These laws set
certain standards that govern water quality.

Some of our water sources in the southern area of the São Paulo Metropolitan Region contain low quality water due
to the effects of pollution and algae growth.  Currently, we successfully treat this water to make it potable; however,
during dry periods of the year, this water retains an unpleasant taste and odor in spite of the treatment.  If restrictions
on  the  use  of  water  are  imposed  in  the  future  and  if  advanced  treatment  standards  are  not  implemented,  water
originating from this area may decrease in quality and our customers may use only limited amounts of, or refuse to
pay for, this lower quality water.

We have 15 laboratories that monitor water quality and purity as required by standards set by us and as required by
law, which employ approximately 200 technicians, biologists, engineers and chemists.  Our laboratories perform an
average of 130,000 analyses per month.  Our central laboratory located in the City of São Paulo is responsible for
organic compound analysis using the chromatographic and spectrometric methods, as well as heavy metals analysis
by atomic absorption technique.  Five of our laboratories in the São Paulo Metropolitan Region have obtained ISO
9001/2000 certification and three in our Regional Systems have obtained ISO 17025 certification with respect to the
quality of our management systems and the technical ability of our laboratories to produce results.

In addition, we have implemented the “Real Time Water Quality Monitoring System for the São Paulo Metropolitan
Region.”  Under this system, the water of some reservoirs located in the São Paulo Metropolitan Region is tested by
5 probes equipped with six sensors each attached to buoys which are set at different depths.  This equipment permits
us to make up to 17,000 analyses per probe per month.

Water Source Program.  From time to time, we face significant problems with algae growth, as it causes water to
have an unpleasant taste and odor.  In order to minimize this problem, we have implemented additional treatment
processes such as absorption by powdered activated carbon and oxidation by potassium permanganate.  We believe
that  all  the  chemicals  used  are  safe  for  human  consumption,  but  the  algae  problem  creates  significant  additional
costs because of the higher volumes of chemicals used to treat the raw water.

Algae growth tends to occur mainly in the Guarapiranga Reservoir, but it has also been frequently detected in the
reservoirs that compose the Rio Grande and Alto Tietê systems.  Algae growth in the Guarapiranga and Rio Grande
reservoirs is basically  due  to  the  discharge of  untreated  sewage  from  squatters  living  adjacent  to  the reservoirs  in
violation of laws intended to protect the watershed.  In the Alto Tietê system the algae growth is mainly caused by
effluents from the agricultural use of the drained areas.

We  are  planning  to  participate  in  the  Water  Source  Program  (Programa  Mananciais)  together  with  other
organizations engaged on the promotion of urban development and social inclusion to mitigate the pollution problem
in the Guarapiranga and Rio Grande reservoirs.  In this program, we will be responsible for the expansion of sewage
systems, pre-treatment of streams and development more sophisticated treatment facilities.

33

We  believe  that  there  are  no  material  instances  where  our  standards  are  not  being  met.    However,  we  cannot  be
certain that future breaches of these standards will not occur.

Fluoridation.    As required by  Brazilian  law,  we  have  adopted  a  water  fluoridation  program  which  is  designed  to
assist in the prevention of tooth decay among the population.  Fluoridation primarily consists of adding fluorosilicic
acid to water at 0.7 parts per million.  We add fluoride to the water at our treatment facilities prior to its distribution
into the water supply network.

Sewage Operations

We are responsible for the collection of sewage through our sewage systems and for its subsequent disposal with or
without  prior  treatment.    As  of  December 31,  2004,  we  collected  approximately  82%  and  73%  of  all  the  sewage
produced in the municipalities in which we operate in the São Paulo Metropolitan Region and the Regional Systems,
respectively,  accounting  for  approximately  78%  of  all  the  sewage  produced  in  the  municipalities  in  which  we
operate in the state of São Paulo.

Sewage System.  The function of our sewage system is to collect, transport and treat sewage.  As of December 31,
2004,  we  were  responsible  for  the  operation  and  maintenance  of  36,435  kilometers  of  sewer  lines  of  which
approximately  17,586  kilometers  are  located  in  the  São  Paulo  Metropolitan  Region,  and  18,849  kilometers  are
located in the Regional Systems.

The  following  table  sets  forth  the  total  number  of  kilometers  of  sewage  lines  and  the  total  number  of  sewage
connections in our network for the periods indicated.

Our sewage system comprises a number of systems built at different times and constructed primarily from clay pipes
and, more recently, PVC tubing.  Sewer lines larger than 0.5 meters in diameter are primarily made of concrete.  Our
sewer  system  is  generally  designed  to  operate  by  gravitational  flow,  although  pumping  stations  are  required  in
certain parts of the system to ensure the continuous flow of sewage.  Where pumping stations are required, we use
sewer lines made of cast iron.

Industrial  sewage  can  vary  in  nature  and  concentration  of  contaminants.    The  standards  for  disposal  of  industrial
effluents  are  set  by  Article  19A  of  State  Decree  No. 8,468  of  September  8,  1976,  as  amended,  and  broadly
correspond to the standards for such disposal set by the U.S. Environmental Protection Agency.  The basic premise
of  these  standards  is  that  industrial  effluents  interfere  with  the  natural  biological  process  occurring  at  sewage
treatment facilities and, therefore, such effluents must be treated so that the final effluent meets the parameters set
forth  in  State  Decree  No. 8,468.    This  decree  requires  industries  that  produce  industrial  sewage  to  pre-treat  such
sewage so that levels of certain parameters, such as pH, temperature, sediments, grease, oil and metals are reduced
to environmentally sound levels prior to release into our sewer lines.  To ensure compliance with Article 19A, we
periodically analyze sewage produced by each industrial customer to check whether the customer has complied with
the requirements of the decree.  Although we may take certain actions which include imposing penalties or cutting a
customer’s connection in the event that customer is continuously not in compliance, we are not responsible for and
are not obligated to ensure the compliance of our customers with the requirements of this decree.

Effluents from our sludge treatment facilities (Estações de Tratamento de Esgotos—ETEs) shall comply with flow
and quality standards established by Federal and State regulations.  Flow standards are related to the composition of
effluents  before  being  discharged  into  water  bodies,  while  quality  standards  measure  the  condition  of  the  water
bodies after the dilution of effluents.  Both flow and quality standards will vary according to the expected use of the
relevant water body:  the more important the use of the water body, the more stringent the standards applicable.

34

We consider the condition of the sewer lines in the São Paulo Metropolitan Region generally to be adequate.  Due to
greater  volume  of  sewage  collected  and  to  higher  population  and  commercial  and  industrial  development,  the
condition  of  the  sewer  lines  in  the  São  Paulo  Metropolitan  Region  is  somewhat  worse  than  that  of  the  Regional
Systems.    To  counteract  the  effects  of  deterioration,  we  maintain  a  continuing  program  for  the  maintenance  of
sewage lines intended to deal with anticipated fractures arising from obstructions caused by system overloads.

Unlike  the  São  Paulo  Metropolitan  Region,  the  interior  region  does  not  generally  suffer  obstructions  caused  by
sewage system overload.  The coastal region however experiences obstructions in its sewer lines primarily due to
infiltration of sand, especially during the rainy season in the summer  months.  In addition, the number of sewage
connections in the coastal region is significantly lower than in the other regions serviced by us, with approximately
49% of all residences in the coastal region currently connected to our sewage network.

New sewage connections are made on substantially the same basis as connections to water lines:  we assume the cost
of  installation  for  the  first  15  meters  of  sewer  lines  from  the  sewage  network  to  residential  and  commercial
customers’  sewage  connections  and  the  customer  is  responsible  for  the  remaining  costs.    Industrial  customers  are
responsible for the entire cost of extension and connection to the sewage network.

The following table sets forth projected new sewage connections for the periods indicated.

Sewage  Treatment  and  Disposal.    For  2004  approximately  60%  and  69%  of  the  sewage  we  collected  in  the  São
Paulo Metropolitan Region and the Regional Systems respectively, or 63% of the sewage we collected in the state of
São  Paulo,  was  treated  at  our  treatment  facilities  and  afterwards  discharged  into  receiving  water  bodies  such  as
inland  waters  and  the  Atlantic  Ocean,  in  accordance  with  applicable  legislation.    Our  sewage  treatment  facilities
have a finite capacity.  Flows in excess of such capacity are discharged directly, untreated, to inland waters and the
Atlantic Ocean.  Currently we operate 431 sewage treatment facilities and eight ocean outfalls.

The purpose of sewage treatment is to reduce the polluting impact of the incoming sewage in order to comply with
State Decree No. 8,468, of which stipulates maximum concentrations of certain substances prior  to  discharge  into
the environment.  Although the flow and composition  of  sewage  arriving  at  sewage  treatment  facilities  varies, on
average  more  than  98.0%  of  its  content  is  water.    Our  sewage  treatment  relies  essentially  on  physical  separation
processes  and  on  natural  biological  processes  to  break  down  organic  matter  and  reduce  the  amount  of  harmful
organisms and chemicals.

The primary treatment process is the principal separation process for suspended solid material present in untreated
sewage.  The sewage is passed into sedimentation tanks.  Solid matter settles to the bottom of the tanks, is removed
as sludge and is then passed to the sludge treatment process.  The sewage remaining after this sedimentation process
is either given activated sludge treatment or may be discharged to receiving waters.

The activated sludge treatment process, the principal method for secondary treatment of sewage used by us, relies on
natural bacterial action to break down the organic matter in sewage and, where required, to remove ammonia.  In the
activated  sludge  treatment  process,  the  sewage  from  primary  treatment  is  passed  into  aeration  tanks  which  are
continuously  replenished  with  recirculated  activated  sludge.    The  mixture  in  the  tanks  is  agitated  and  aerated
enabling the micro-organisms in the activated sludge to digest organic material contained in the incoming sewage.
The effluent and activated sludge mixture produced by this process flows over to the final sedimentation stage.

We operate 41 activated sludge treatment facilities, each of which also contains a primary treatment facility.  The
five  largest  activated  sludge  treatment  facilities  located  in  the  São  Paulo  Metropolitan  Region  have  treatment
capacity of approximately 18 cubic meters of sewage per second.

35

Sewage  treatment  in  the  Regional  Systems  will  vary  according  to  the  particularities  of  each  area.    In  the  interior
region treatment consists largely of aeration ponds where the organic matter is aerobically digested and the treated
sewage is discharged to receiving waters.  There are 340 secondary treatment facilities in the interior region which
have treatment capacity of approximately 9.6 cubic meters of sewage per second.

The  majority  of  sewage  collected  in  the  coastal  region  receives  secondary  treatment  and  disinfection  and  is  then
discharged into rivers and into the Atlantic Ocean.  We have 66 sewage treatment facilities in the coastal region.

Our  trunk  lines  are  currently  not  sufficiently  extensive  to  transport  all  sewage  collected  by  us  to  our  treatment
facilities.  As a result, a portion of the sewage collected by us is released untreated into receiving waters, resulting in
high  levels  of  pollution  in  such  bodies  of  water.    Our  capital  expenditure  plan  includes  projects  to  increase  the
amount of sewage that we treat.  See “—Government Regulation—Sewage Requirements” below.

Sludge Disposal.  Sludge removed from the primary and secondary treatment processes typically contains water and
a  very  small  proportion  of  solids.    We  use  filter  presses,  belt  presses  and  centrifugation  machines  to  abstract  the
water from the sludge.  In 2004, we produced approximately 43,932 tons of sludge-dry base, of which 39,609 tons
were discharged into landfills and the remainder was used for agricultural purposes.  In addition, we are testing new
technologies for sludge disposal as fertilizer in forest projects, fuel development and concrete manufacturing.

In addition to serving residential, commercial, industrial and governmental customers in municipalities in which we
hold  concessions,  we  currently  make  wholesale  sales  of  water  to  six  municipalities  having  a  total  estimated
population of 3.1 million.  The State is our largest customer.

Tariffs

Tariffs have historically been adjusted once a year and for periods of at least 12 months.  We raised tariffs in June
2001, in July 2002 and in August 2003.  Effective August 29, 2004, we increased our tariffs for water and sewage
services by 6.8%.

Although  we  have  the power  to  set our  tariffs  for  water  and  sewage  services,  we  traditionally  have  consulted  the
Governor of the State prior to setting new tariff rates.  For example, we did not increase tariffs in 2000 due to a State

36

policy  for  the  year  of  not  increasing  tariff  rates  for  some  public  carriers,  such  as  public  transportation  and  water
supply services.

The most recently implemented tariff regulations allow us to more aggressively set tariffs and to more realistically
cover the operational costs of water and sewage systems.  In addition, the new tariff regulations allow us to calculate
the water and sewage service tariffs in order to better adequate the tariff value to the peculiarities of each service, the
diversity of the regions covered and the social and economic conditions of the end user.

We established a new tariff schedule, effective May 2002, for commercial and industrial customers that consume at
least  5,000  cubic  meters  of  water  per  month  and  that  enter  into  demand  agreements  with  us  for  at  least  one-year
terms.    We  believe  this  new  tariff  schedule  will  help  prevent  our  commercial  and  industrial  customers  from
switching to the use of private wells.

On  August  29,  2003,  we  developed  and  implemented  a  new  readjustment  formula  for  our  tariffs  to  better  reflect
changes  in  our  cost  structure.    According  to  this  new  formula,  the  cost  components  of  the  Tariffs  Readjustment
Index (IRT) are separated into two parts (“A” and “B”), where Part “A” encompasses all costs related to electricity;
water and sewage treatment materials; federal, State and local taxes; and financial compensation due to use of water
resources and where Part “B” encompasses all other costs and expenses.  The readjustment of Part “A” is based on
the price variation observed in its components during the preceding 12-month period.  Part “B” is adjusted by the
Extended  Consumer  Price  Index  (Indice  de  Preços  ao  Consumidor  Ampliado—IPCA).    As  part  of  the  Alto  Tietê
project we have undertaken a project aimed at evaluating and potentially revising our current tariff structure in order
to improve our return on investment.

We establish separate tariff schedules for our services in each of the São Paulo Metropolitan Region and each of the
interior and coastal regions which comprise our Regional Systems.  Each tariff schedule incorporates cross-subsidies
pursuant  to  which  certain  customers,  in  effect,  subsidize  the  provision  of  water  and  sewage  services  to  other
customers.    Customers  with  high  monthly  water  consumption  rates  pay  higher  tariffs  than  our  costs  of  providing
such water service.   We use  the  excess  tariff  billed  to high volume  customers  to  compensate  for  the  lower  tariffs
paid  by  low-volume  customers.    Similarly,  tariffs  for  non-residential  customers  are  established  at  levels  that
subsidize residential customers.  In addition, the tariffs for the São Paulo Metropolitan Region generally are higher
than tariffs in the interior and coastal regions.

We divide tariffs into two categories:  residential and non-residential.  The residential category is sub-divided into
basic residential, social and favela (shantytowns).  The residential social tariffs apply to residences of low income
families which live in sub-standard conditions, residences of persons unemployed for up to 12 months and collective
living  residences.    The  favela  tariffs  apply  to  residences  in  shantytowns  characterized  by  a  lack  of  urban
infrastructure.  The latter two sub-categories were  instituted  to  assist  lower-income  customers  by providing  lower
tariffs for consumption.  The non-residential category consists of:

•

•

•

privately-owned companies, government entities and industrial customers;

“not-for-profit” entities that pay 50.0% of the prevailing non-residential tariff; and

government entities that have entered into a water loss reduction agreement with us and pay 75.0%
of the prevailing non-residential tariff.

Sewage charges in each region are fixed as a function of the monthly water charges.  In the São Paulo Metropolitan
Region and the coastal region, the sewage tariffs equal the water tariffs.  In the interior region, sewage tariffs are
approximately 20% lower than water tariffs.  Wholesale water rates are the same for all municipalities served.  We
also  make  available  sewage  treatment  services  to  those  municipalities,  although  no  formal  agreement  for  the
provision of these services has been signed as of the date of this document.  In addition, various industrial customers
pay an additional sewage charge, depending on the characteristics of the sewage they produce.

37

The following table sets forth the water and sewage services tariffs by customer category charged during the years
and  period  stated  in  the  São  Paulo  Metropolitan  Region,  which  accounted  for  approximately  74.5%  of  our  net
revenue from sales and services in 2004.

The  average  annual  tariffs  we  charge  in  the  interior  and  coastal  regions  for  the  provision  of  water  and  sewage
collection  during  2004  were  32.0%  and  17.0%  below  the  tariffs  charged  in  the  São  Paulo  Metropolitan  Region,
respectively.

In  October  2004  we  began  a  tariff  study  conducted  by  an  international  consortium  and  sponsored  by  the  Inter-
American  Development  Bank,  which  we  estimate  will  take  approximately  18  months  to  complete.  The  study  is
focussed on tariff restructuring and marketing orientation. The study has three stages:  (i) a new tariff scheme; (ii)
the  creation  of  a  marketing  plan  and  (iii)  improvements  in  commercial  practice.    We  cannot  give  any  assurances
with respect to whether any of the study’s recommendations will be adopted.

See  “—Government  Regulation—Tariff  Regulation  of  São  Paulo”  below  for  additional  information  regarding  our
tariffs.

Billing Procedures

The procedure  for billing  and  payment  of  our  water  and  sewage  services  is  basically  the  same  for  each  customer
category.  Water and sewage bills are based upon water usage determined by monthly water meter readings.  Larger

38

                             
customers, however, have their meters read every 15 days to avoid non-physical losses resulting from faulty water
meters.  Sewage billing is included as part of the water bill and is based on the water meter reading.

We deliver all water and sewage bills by hand to our customers, mainly through independent contractors who are
also responsible for reading water meters.

Water and sewage bills can be paid at some banks and other locations in the state of São Paulo.  These funds are
paid over to us and average service fees between R$0.36 and R$1.07 per transaction are charged for collection and
remittance of these payments.

Customers must pay their water and sewage bills by the due date for payment if they wish to avoid paying a fine.
We generally charge a penalty fee and interest on late bill payments.  However, we do not assess a penalty fee or
interest  in  respect  of  governmental  customers.    In  2002,  2003  and  2004  we  received,  respectively,  payment  of
94.5%, 90.9% and 94.1% of the amount billed to our retail customers, and 94.6%, 93.8% and 94.4% of the amount
billed to those customers other than State entities, within 30 days after the due date.  Almost all of the amount not
paid within 30 days is owed by State customers.  With respect to wholesale sales, in 2004 we received payment of
43.7% of the amount billed within 30 days.

In  the  São  Paulo  Metropolitan  Region  we  monitor  water  meter  readings  by  use  of  hand-held  computers  and
transmittors.    The  system  allows  the  meter  reader  to  input  the  gauge  levels  on  the  meters  into  the  computer  and
automatically  print  the  bill  for  the  customer.    The  hand-held  computer  tracks  water  consumption  usage  at  each
metered location and prepares bills based on actual meter readings.  We outsourced this billing system to third-party
contractors  that  employ  and  train  their  own  meter  readers  whose  training  we  supervise.    We  have  water  meter
reading  and  printing  by  hand-held  computers  in  some  municipalities  that  we  serve  in  the  Regional  Systems  and
intend to expand this system in other municipalities we serve.

Research and Development

Our  policy  is  to  invest  continually  in  the  modernization  of  equipment  and  in  the  technology  needed  to  identify,
evaluate  and  improve  our  provision  of  basic  sanitation  services  while  promoting  environmental  protection  and
maintaining  our  competitiveness  and  profitability.    Our  research  and  development  function  is  divided  into
committees  according  to  strategy  and  complexity.    We  have  historically  spent  up  to  R$3.0 million  per  year  on
research and development.  We have also partnered with several research institutions.

Electricity Consumption

The use of electricity is material to our operations, and as a result we are one of the largest users of electricity in the
state of São Paulo.  We obtain electricity primarily from Companhia Energética São Paulo (CESP) pursuant to  a
long term contract expiring in 2012.  To date, we have not experienced any major disruptions in electricity supply.
Any  significant  disruption  of  electricity  to  us  could  have  a  material  adverse  effect  on  our  business,  financial
condition, results of operations or prospects.

Electricity  prices  have  a  significant  impact  on  our  results  of  operations.  An  average  increase  of  17.5%  in  2004
negatively  impacted  our  results  of  operations.    See  “Item  5.    Operating  and  Financial  Review  and  Prospects—
Results of Operations” above.

Capital Expenditure Program

Currently, our capital expenditure program is designed to improve and expand our water and sewage system and to
increase and protect our water sources in order to meet the growing demand for water and sewage services in the
state of São Paulo.  Our capital expenditure program has four specific targets in the municipalities we serve:

•

to continue to meet the maximum demand for treated water;

39

•

•

•

to expand the percentage of households connected to our sewer system;

to increase the treatment of sewage collected; and

to increase operating efficiency and reduce water losses.

From 1998 through 2004, our capital expenditure program included capital expenditures totaling R$4.8 billion in the
aggregate, primarily to build up our infrastructure and for our program to reduce water losses.  We have budgeted
capital expenditures totaling approximately R$4.2 billion in the aggregate during the period between 2005 and 2009.
We spent approximately R$600.9 million in 2004.

The following table sets forth our planned capital expenditures for water and sewage for the years indicated.

Our capital expenditure program from 2005 through 2009 will continue to focus on achieving our targets by making
regular  investments  in  and  expanding  our  infrastructure  as  well  as  making  investments  in  our  program  for  the
reduction of water losses throughout the 368 municipalities which we serve.  The following is a brief description of
three of the principal projects in our capital expenditure program.

Metropolitan Water Project

Demand  for  our  water  services  has  grown  steadily  over  the  years  in  the  São  Paulo  Metropolitan  Region  and  has
exceeded at  times  the  capacities of our  water  systems  there.    As  a  result, prior  to September  1998,  certain  of  our
customers in this region received water only on certain days of the week.  We refer to this as “rotation.”  In order to
remedy this situation, we implemented the Metropolitan Water Project to improve regular water supply to the entire
São Paulo Metropolitan Region.  We have budgeted for capital expenditures of approximately R$661 million from
2005 through 2009.

Tietê Project

The  River  Tietê  crosses  the  São  Paulo  Metropolitan  Region  and  receives  most  of  the  Region’s  run-off  and
wastewater.  The Tietê Project is designed to reduce pollution of the River Tietê by installing sewage collection lines
along the banks of the River Tietê and its tributaries.  These lines collect raw sewage and deliver it to our sewage
treatment facilities.  In connection with the first phase of the Tietê Project, in June 1998, we completed construction
of three additional sewage treatment plants and invested a total of U.S.$900.0 million, of which U.S.$450.0 million
was financed by the Inter-American Development Bank and U.S.$450.0 million was funded by us.

We  made  capital  expenditures  with  respect  to  the  first  phase  of  the  Tietê  Project  of  U.S.$900.0 million.    As  of
December  31,  2004,  we  owed  U.S.$328.2 million  to  the  Inter-American  Development  Bank  for  the  financing  it
provided.    We  now  provide  secondary  treatment  to  approximately  60%  of  the  sewage  collected  in  the  São  Paulo
Metropolitan  Region.    The  five  principal  sewage  treatment  plants  in  the  São  Paulo  Metropolitan  Region  have  an
aggregate installed capacity of 18 cubic meters of sewage per second and currently treat an aggregate of 10.9 cubic
meters  of  sewage  per  second.    Currently,  raw  sewage  is  delivered  to  our  secondary  treatment  facilities  along  the
River  Tietê  and  the  River  Tamanduatei  before  treated  sewage  is  discharged  into  those  rivers.    We  plan  to  build
additional collection lines to direct more raw sewage to our treatment facilities.

We  are  currently  in  the  second  phase  of  the  Tietê  Project,  for  which  we  have  budgeted  for  additional  capital
expenditures  of  approximately  U.S.$400.0 million  from  2000  through  2007,  U.S.$200.0 million  of  which  will  be
financed by the Inter-American Development Bank.  We have also entered into a loan agreement and an on-lending

40

agreement  with  BNDES  for  R$60.0 million  and  R$180.0 million,  respectively,  to  finance  this  second  phase.
Through December 31, 2004, we have spent U.S.$186.2 million on this phase of the Tietê Project.

As  part  of  the  second  phase  of  the  Tietê  Project  we  implemented  the  geographic  information  system  named
SIGNOS.    SIGNOS  is  a  management  information  system  which  automates  and  integrates  various  business
processes,  including  project  management,  maintenance,  operations  and  customer  service  and  maps  out  our  entire
municipal infrastructure in the São Paulo Metropolitan Region.  In addition, this phase included the undertaking of a
project  aimed  at  evaluating  and  potentially  revising  our  current  tariff  structure  in  order  to  cover  the  systems
operation and maintenance costs and appropriately remunerate current and future investments.  This project is also
financed by our loan with the Inter-American Development Bank.

Regional Systems Investment Programs

We  currently  have  a  number  of  projects  in  progress  and  planned  for  the  Regional  Systems,  including  projects
relating to abstraction of water and collection and treatment of sewage.  We spent R$321.8 million, R$195.0 million
and  R$212.0 million on  such  projects  in 2002, 2003  and 2004, respectively,  and  we  have  budgeted  for  additional
capital expenditures of approximately R$1.2 billion in the period from 2005 to 2009.

Environmental Recovery Program for the Baixanda Santista Metropolitan Region

On August 6, 2004, we entered into a credit agreement with the Japan Bank for International Cooperation for the
financing  of  the  Environmental  Recovery  Program  for  the  Baixada  Santista  Metropolitan  Region,  which  was
guaranteed by the Republic of Brazil, for a total amount of R$588.0 million.  The total investment to be made with
respect to this project is R$1,081 million and the balance will be our responsibility.  No disbursement has been made
yet on this loan.  The main goals of this program are to improve and expand the water and sewerage systems in the
municipalities making up the Baixanda Santista Metropolitan Region.

Competition

In general, we do not face any competition in the municipalities in which we provide water and sewage services, and
we believe that in those municipalities we have an exclusive right to provide such services.  We do not serve, either
directly or on a wholesale basis, 272 municipalities in the state of São Paulo that operate their own water and sewage
systems  and  that  collectively  have  a  population  of  approximately  12.0 million,  or  approximately  30%  of  the
population of the state of São Paulo.  In addition, private water companies provide several municipalities with water
and sewage services pursuant to concessions from such municipalities.

We face  a  limited  level of competition  with  respect  to  the  supply of  water  to  industrial  customers.    Several  large
industrial  customers  located  in  municipalities  served  by  us  use  their  own  wells  to  supply  themselves  with  water.
This use of private wells has been increasing in recent years.  We have established new tariff schedules commercial
and industrial customers in order to help retain such customers.  We do not experience any competition with respect
to the sewage collection services we provide to industrial customers.

Government Regulation

In Brazil, water and sewage services, although not specifically regulated, are subject to extensive Brazilian federal,
state and, in certain respects, local laws and regulations governing, among other things:

•

•

•

•

the granting of concessions to provide water and sewage services;

public bidding requirements for appointment of water and sewage service provider;

water usage;

water quality and environmental protection;

41

•

•

General

tariffs for water and sewage services; and

governmental  restrictions  on  the  incurrence  of  indebtedness  (which  are  applicable  to  state-
controlled companies).

Pursuant to Article 23 of the Brazilian Constitution, water and sewage services are the common responsibility of the
Brazilian government, the states and the municipalities.

Article  216  of  the  State  Constitution  provides  that,  by  law,  the  State  must  provide  the  conditions  for  efficient
management  and  adequate  expansion  of  water  and  sewage  services  rendered  by  its  agencies  and  State-controlled
companies or any other concessionaire under its control.  State law authorized our formation to plan, provide and
operate water and sewage services in the State and also acknowledged the autonomy of the municipalities.

Pursuant to Article 175 of the Brazilian Constitution, the furnishing of public  services,  such  as water  and  sewage
services, is the responsibility of the applicable public authority.  However, any such public authority has the right to
furnish these services directly or through a concession granted to a third party.

Pending Legislation

On  May  23,  2005,  a  new  proposed  law  (“Proposed  Law  No.  5,296”)  was  submitted  to  the  Brazilian  House  of
Representatives.  The proposed law does not define whether the entity responsible for sanitation services will be the
state or the municipality, but divides sanitation services into two categories: “local interest” sanitation services and
“integrated’ sanitation services.  Services in connection with the distribution of water and sewage collection will be
attributed  to  the  local  interest,  and  thus  the  municipality  will  always  be  the  entity  responsible  for  those  services.
Other services, such as water treatment, may also considered to be of local interest, if they are rendered to a single
municipality,  otherwise  they  will  be  considered  to  be  of  integrated  interest.    A  state,  however,  might  also  be
responsible for those services if it enacts a State Complementary Law which establishes metropolitan areas, urban
agglomerations and micro-regions and includes those services in the category of common interest sanitation services
to be planned, regulated, and controlled by that state.

According  to  Proposed  Law  No.  5,296, any  entity  responsible for  sanitation  services will  be required  to  abide  by
guidelines relating to planning, regulating, and controlling those services.  If the entity responsible does not follow
those guidelines, it will not be eligible for voluntary funds from the Federal Government.  The provision of sanitary
services, either in the local interest or the integrated interest, may be made by the responsible entity itself, by state
companies  created  to  provide  that  service,  or  indirectly  by  concession  or  an  agreement  between  the  responsible
entity and any other state or private company.  In any case, the entity responsible for the provision of the services
will not be able to plan, regulate or fix tariffs.

Proposed Law No. 5,296 is being analyzed by the House of Representatives and has recently been attached to other
proposed federal laws, in connection with the regulation of sanitation services.

Additionally, Proposed Law No. 155/2005 has also recently been submitted to the Brazilian Federal Congress.  This
proposed  law,  which  has  been  under  consideration  by  the  Brazilian  Senate  since  May  11,  2005,  does  not  define
whether  the  entity  responsible  for  the  sanitation  services  will  be  the  state  or  the  municipality,  but  it  also  divides
sanitation services into two categories: “local interest” sanitation services and “common interest” sanitation services.
According  to  the  proposed  law,  the  holder  of  the  sanitation  services  will  define  the  entity  responsible  for  the
regulation  of  those  services,  and  will  establish,  among  other  things  investment  plans  and  tariff  policies.    This
proposed law also provides that the provision of sanitation services may be interrupted if the user of those services
does not make timely payments.

Proposed  Law  No  4,147,  however,  which  had  been  under  consideration  by  the  Brazilian  Federal  Congress  since
February 21, 2001, has recently been dismissed and is no longer under review by the Brazilian Federal Congress.

42

The  legislature  of  the  State  is  also  considering  adopting  a  law  which  would  establish  a  State  regulatory  agency
responsible for regulating and controlling public sanitation services in the state of São Paulo.  This proposed agency
would be part of the Energy, Water Resources and Sanitation Secretariat of the State.

The legislature of the State is also debating new legislation that would establish procedures for the collection of fees
related to the use of water from resources under the state of São Paulo.

We cannot assure you when or if any of the legislation described above will be adopted, the final form of these laws
if they are approved, or how this legislation would affect our business.

Concessions

Concessions for water and sewage services are evidenced by contracts between the state or municipal government,
as the case may be, and a concession under which the concessionaire is granted the right to supply these services in a
particular  municipality  or  region.    Our  concessions  usually  have  a  contractual  term  of  not  longer  than  30  years,
although  a  number  of  our  concessions  are  of  unlimited  duration.    However,  our  concessions  generally  may  be
terminated at any time if certain quality and safety standards are not met or if there is a default under the concession
contract.    A  majority  of  our  concessions  are  automatically  renewable,  though  we  often  renegotiate  terms  and
conditions  unless  notice  of  rescission  is  received  by  the  non-rescinding  party  at  least  six  months  prior  to  the
expiration date of the concession.  A municipality that elects to take control of its water and sewage services must
either provide such services itself, auction the concession to potential concessionaires through a competitive public
bidding process, or enter into agreements with a public entity directly.  Although the State Constitution provides that
the  relevant  municipality  would  have  to  pay  us  the  non-amortized  book  value  of  our  assets  relating  to  that
concession and assume any related indebtedness, exclusive of any amounts paid to us by the relevant municipality
upon  any  termination  or  non-renewal  of  a  concession,  such  a  termination  payment  may  not  be  paid  and  any
termination  could  adversely  affect  our  cash  flows,  results  of  operations  and  financial  condition.    In  addition,
municipalities hold elections for the office of Mayor every four years.  If certain municipalities choose not to renew
their concessions, it could adversely affect our cash flows, results of operations and financial condition.

Federal legislation enacted in 1995, and subsequently amended, governs the granting of concessions in Brazil.  The
Federal  Concessions  Law  regulates  the  granting  of  concessions  by  federal,  state  and  municipal  governments.    In
addition, the Federal Public Bidding Law sets forth the bidding procedures related to the granting of concessions.
At the São Paulo State level, the State Concessions Law corresponds to the Federal Concessions Law, and the State
Public Bidding Law corresponds to the Federal Public Bidding Law.  In the event of any conflict between federal
and state law, federal law prevails.

Concessions Laws

The Federal Concessions Law and the State Concessions Law require that a concession granted by a public entity be
based  on  a  public  bidding  process.    The  Federal  Public  Bidding  Law  provides,  however,  that  the  public  bidding
process can be waived in certain circumstances, including in the case of services to be rendered by a public entity
created for such specific purposes prior to the enactment of that law, provided that the prices for such services are
compatible with those prevailing in the market.  In addition, a provision of the Brazilian Constitution provides for
waivers  of  the  public  bidding  requirement  in  similar  situations.    Based  on  this  provision,  we  were  granted
concessions  by  municipalities  after  enactment  of  the  Brazilian  Constitution  without  a  public  bidding  process,
although  under  current  law  we  may  be  required  to  bid  to  acquire  new  concessions.    We  did  not  have  any  of  our
concessions cancelled or revoked following promulgation of the Federal Concessions Law.  The requirements of the
Federal  and  State  Concessions  Laws  will,  however,  govern  the  grant  of  new  concessions  to  us  in  the  future.    In
February 1998, the Attorney General of the State, in response to a request we made, delivered an opinion that any
municipality in the state of São Paulo may grant to us a concession to operate the municipality’s water and sewage
services  without  having  to  resort  to  a  public  bidding  process.    In  April  1998,  a  State  court  issued  a  judgment
substantially to the same effect.  There can be no assurance that the Brazilian courts will continue to interpret the
concessions laws to allow municipalities to grant concessions without a public bidding process.

43

The legislature of the City of São Paulo approved Law No. 13,670 of November 25, 2003, which regulates article
148  and  the  sole  paragraph  of  article  149  of  the  Organic  Law  of  the  Municipality  of  the  City  of  São  Paulo,
concerning water supply and sewage public services, establishes the Municipal Regulation System of Water Supply
and  Sewage  Public  Services,  creates  the  Regulatory  Authority  for  Water  and  Sewage  Services  of  São  Paulo,
addresses  its  organization  and  operation  and  establishes  the  Municipal  Sanitation  Plan.   Pursuant  to  this  Law,  the
Mayor of the City of São Paulo has authority to grant and monitor formal concessions for water and sewage services
in the Municipality of the City of São Paulo.  Following the enactment of Law No. 13,670, the Governor of the State
has  filed  a  legal  action  alleging  that  the  Law  is  unconstitutional,  as  a  result  of  which,  the  enforcement  of  Law
No. 13,670  had  been  suspended.    On  April  20,  2005,  the  court  ruled  in  favor  of  the  governor  of  the  State,  by  a
majority  of  votes;  the  court’s  judgement  had  not  yet  been  drawn  up  as  of  the  date  of  this  annual  report.    The
provisions of the State Concessions Law parallel the provisions of the Federal Concessions Law.

Public Consortiums Law

On April 6, 2005, the Brazilian Federal Government enacted Law No.º 11.107, which regulates article 241 of the
Brazilian  Constitution.    This  new  regulation  provides  general  principles  to  be  observed  when  public  consortiums
enter  into  contracts  with  the  Brazilian  political  divisions  and  subdivisions  (the  Federal  Government,  States,  the
Federal  District  and  Municipalities)  aiming  at  the  joint  management  of  public  services  of  common  interests.
Considering  the  nature  of  the  services  rendered  by  us,  it  is  possible  that,  in  the  future,  the  Company  may  have
interest and/or opportunity to contract in a manner provided for in this newly enacted law in order to regulate the
relationship with some municipalities to which it renders basic sanitation services.

Public Bidding Procedures

Pursuant  to  the  Federal  Public  Bidding  Law,  the  public  bid  process  commences  with  publication  by  the  granting
authority  in  the  federal,  state  or  municipal  official  gazette,  as  the  case  may  be,  and  another  leading  Brazilian
newspaper, of an announcement that it will carry out a public bidding contest pursuant to provisions set forth in an
edital (invitation to bid).  The invitation to bid must specify, among other terms:

•

•

•

•

•

the purpose, duration and goals of the bid;

a  description  of  the  qualifications  required  for  adequate  performance  of  the  services  covered  by
the bid;

the deadlines for the submission of bids;

the criteria used for selection of the winning bidder; and

a list of the documents required to establish the bidder’s technical, financial and legal capabilities.
The  invitation  to  bid  is  binding  on  the  granting  authority.    Bidders  may  submit  their  proposals
either individually or in consortia, as provided for in the invitation to bid.

After  receiving  proposals,  the  granting  authority  will  evaluate  each  proposal  according  to  the  following  criteria,
which must have been set forth in the invitation to bid:

•

•

•

•

the technical quality of the proposal;

lowest cost or lowest public service tariff offered;

a combination of the criteria above; or

the largest amount offered in consideration for the concession.

The provisions of the State Public Bidding Law parallel the provisions of the Federal Public Bidding Law.

44

The federal and State bidding laws will apply to us in the event that we seek to secure new concessions.  Moreover,
these bidding laws currently apply to us with respect to obtaining goods and services from third parties for, among
other things, our business operations or in connection with our capital expenditure program, in each case subject to
certain exceptions.

Water Usage

In July 2000, the National Water Agency, a federal agency under the Ministry of the Environment, was established
in  order  to  develop  the  National  System  for  Water  Resources  Management.    Under  proposed  legislation,  the
National  Water  Agency  would  be  responsible  for  the  coordination  of  the  regulatory  aspects  involved  in  the
rendering of water and sewage services.  See “—Pending Legislation” above.

According to existing law, federal and state agencies are authorized to collect fees from other governmental agencies
under their jurisdictions.  In most cases, the fees have yet to be established by implementing regulations.  However,
for one specific water basin (the Rio Paraíba do Sul water basin), water usage legislation was enacted requiring us
to pay the Federal Government or an agency in respect of the use of water, and we started making payments in this
respect on March 2003.

State law establishes the basic principles governing the development and use of water resources in the state of São
Paulo in accordance with the State Constitution.  These principles include:

•

•

•

•

•

•

•

rational utilization of water resources, with service to the population identified as having priority;

optimizing the economic and social benefits resulting from the use of water resources;

protection of water resources against actions which could compromise current and future use;

defense against critical hydrographic events which could cause risk to the health and safety of the
population or economic and social losses;

development of hydro transportation for economic benefit;

development of permanent programs of conservation and protection of underground water sources
against pollution and excessive exploitation; and

prevention of erosion of land in urban and rural areas, with a view to protecting against physical
pollution and silting of water resources.

In order to implement these principles, authorizations granting a right of use are required from the relevant public
authority for water usage (whether for collection, release of effluents or other otherwise), modification of the regime
and  modification  of  the  quality  or  the  quantity  of  the  existing  water.    In  the  case  of  rivers  under  the  Federal
Government’s  domain  (rivers  crossing  more  than  one  state),  the  National  Water  Agency  (Agência  Nacional  de
Águas—ANA)  is  the  public  authority  which  grants  the  authorization.    With  respect  to  the  rivers  under  a  state’s
domain,  the  applicable  state  authority  has  jurisdiction  to  grant  the  right  of  use.    In  the  state  of  São  Paulo,  the
Department of Water and Energy of the State (Departamento de Águas e Energia Elétrica do Estado de São Paulo)
is the public authority responsible for granting such authorizations.  According to a report prepared in May 2001, the
granting of rights for our water usage should be regulated in 391 of our projects.

Under state law, implementation of any project that involves the use of surface or underground water requires prior
authorization or licensing from the competent government authority.

The Department of Water and Energy (Departamento de Águas e Energia Elétrica) of the State has as its objectives
establishing (1) a policy for the use of water resources with a view to developing the water business of the State, and
(2) plans, studies and projects related to the integral use of water resources, directly or by means of agreements with

45

third  parties.    The  Department  of  Water  and  Energy  has  established  the  standards  which  regulate  abstraction  of
water from water resources in the state of São Paulo.

State law provides the basis for the fees charged by governmental water agencies in the state of São Paulo for the
abstraction  of  water  from  the  state  of  São  Paulo’s  water  resources  controlled  by  such  agencies.    Although
governmental water agencies in the state of São Paulo currently do not charge fees for any of the water which we
abstract, there can be no assurance that such fees will not be charged in the future.

Water Quality

An  ordinance  issued  by  the  Ministry  of  Health  (Ministério  da  Saúde)  of  the  Brazilian  government  sets  forth  the
standards of potability of all water for human consumption in Brazil.  This ordinance is modeled on the U.S. Safe
Drinking  Water  Act  and  regulations  promulgated  by  the  U.S. Environmental  Protection  Agency  thereunder.    The
Secretariat of Health (Secretaria de Estado da Saúde) of the State has also set minimum standards for the potability
of water for human consumption which are more restrictive than the national rules.

We analyze test samples at our laboratories to determine compliance with Ordinance No. 518, of March 25, 2004
and  state  law  using  “Standard  Methods”  (181st.  Edition)  procedures  established  by  the  American  Water  Works
Association.

Sewage Requirements

State law sets forth regulations regarding pollution and protection of the environment in the state of São Paulo.  The
standards  for  disposal  of  industrial  effluents  set  forth  in  this  law  broadly  correspond  to  the  standards  for  such
disposal set by the U.S. Environmental Protection Agency.  State law generally prohibits the discharge of pollutants
into water, air or land in the state of São Paulo.

State law provides that, in areas in which there exists a public sewage system, all effluents of a “polluting source”
must  be  discharged  to  such  system.    It  is  the  responsibility  of  the  polluting  source  to  connect  itself  to  the  public
sewage  system.    All  effluents  to  be  discharged  are  required  to  meet  certain  characteristics,  which  allow  such
effluents to be treated by our treatment facilities and discharged in an environmentally safe manner.  Effluents which
exceed such characteristics are prohibited from being discharged into the public sewage system.  State law requires
industries  that  produce  industrial  sewage  to  pre-treat  such  sewage  so  that  maximum  levels  of  certain  parameters,
such  as  pH,  temperature,  sediment,  grease,  oil  and  metals,  are  reduced  to  environmentally  sound  levels  prior  to
release into our sewer lines.

Environmental  Sanitation  Technology  Company,  or  CETESB  (Companhia  de  Tecnologia  de  Saneamento
Ambiental), a State-controlled company controlled by the Secretariat of the Environment of the State, is authorized
under State law to monitor discharges of pollutants into public waters and to enforce the requirements of State law.
CETESB  has  the  power  to  grant  consents  to  entities  which  are  discharging  pollutants  into  receiving  waters.
Although we have not received formal authorization from CETESB to discharge untreated sewage into waters, we
continue to discharge such sewage.  Our capital expenditure program includes the Tietê Project, which is designed to
reduce the discharge of untreated sewage into the River Tietê, a major river in the São Paulo Metropolitan Region.
CETESB participates in the development of this project.  There can be no assurance that we will not be required in
the future to obtain specific consents or authorizations for discharges of untreated sewage.

The  disposal  of  sludge  must  also  meet  the  requirements  of  State  law.    CETESB  also  regulates  the  discharge  of
effluents into bodies of water under State law and must approve all of our treatment facilities.

State law also provides the basis for fees to be charged for discharging effluents into the state of São Paulo’s water
resources.  Although neither the State nor its agencies currently assesses fees for such discharges, we cannot assure
you that such fees will not be charged in the future.

46

Some municipalities of the state of São Paulo have enacted municipal laws requiring us to charge a fixed fee, and
not a tariff, for sewage services being provided.  To date, we have not acknowledged the enforcement of any such
laws.

Tariff Regulation of São Paulo

The tariffs we set for our services are to some extent subject to Federal and State regulation.

On  December  16,  1996,  the  Governor  of  the  State  issued  a  decree  which  approved  the  existing  tariff  system  and
allowed us to continue to set our own tariffs.  We have set our tariffs based on the general objectives of maintaining
our financial condition and preserving “social equity” in terms of the provision of water and sewage services to the
population while providing a return on investment.    The Governor’s decree  also directs us  to  apply  the  following
criteria in determining our tariffs:

•

•

•

•

•

•

•

category of use;

capacity of the water meter;

characteristics of consumption;

volume consumed;

fixed and floating costs;

seasonal variations; and

social and economic conditions of residential customers.

In  determining  tariffs,  we  may  also  consider  the  costs  associated  with  the  exploitation  of  water  resources,
depreciation,  provision  for  bad  debts,  amortization  of  expenses  and  adequate  remuneration  for  investments.    We
usually submit new tariffs to the Governor of the State for approval, although we are not required by law to do so.
We  implemented  a  new  readjustment  formula  designed  to  better  reflect  costs  in  August  2003.    See  “Item  4.
Information on the Company— Tariffs.”

We  maintain  three  different  tariff  schedules,  depending  upon  whether  a  customer  is  located  in  the  São  Paulo
Metropolitan Region or the interior or coastal regions comprising our Regional Systems.  There are four levels of
volume consumed for each category of customer.  Customers are billed on a monthly basis.  We are also authorized
to enter into individual contracts with certain customers, such as municipalities, to sell water or sewage services on a
wholesale basis.

Tariffs must be published in the Official Gazette of the state of São Paulo (Diário Oficial do Estado de São Paulo).

We may be subject to a Federal law which, in the case of water and sewage services provided pursuant to certain
concessions, effectively prohibits tariffs that would produce a return on assets in excess of 12% per annum.  Return
on  assets  is  calculated  using  operating  income  (before  financial  and  certain  other  expenses)  measured  against
operational  assets  (property,  plant  and  equipment  and  certain  other  assets),  based  upon  our  financial  statements
prepared  in  accordance  with  the  Brazilian  Corporate  Law  Method.    We  could  be  subject  to  the  above  return  on
assets limitation in adjusting tariffs because substantially all of our concessions were granted during the period in
which these rate regulations were in effect.  We are not, however, subject to such limitations in setting tariffs under
our  newer  concessions  or  for  the  City  of  São  Paulo  and  other  municipalities  in  which  we  operate  without  formal
concessions.  The above return on assets limitation does not apply to renewals of existing concessions.

47

Governmental Restrictions on Incurrence of Debt

On  June  30,  1998  the  Central  Bank  issued  a  resolution  amending  certain  conditions  that  must  be  observed  with
respect to the external credit operations (i.e., foreign currency borrowings) of states, the Federal District of Brasilia,
municipalities  and  their  respective  autarquias  (agencies),  foundations  and  non-financial  companies,  including  us.
This resolution provides,  among other  things,  that,  with  certain  exceptions  applicable  to  the  importation  of  goods
and services,

•

•

the  proceeds  of  external  credit  operations  must  be  used  to  refinance  outstanding  financial
obligations of the issuer, with preference given to those obligations that have a higher cost and a
shorter term and until used for such purposes, the proceeds shall remain deposited, as directed by
the Central Bank, in a pledged account; and

the total amount of the contractual obligation be subject to monthly deposits in a pledged account,
equal to the total debt service obligation, including principal and interest, divided by the number
of months that the obligation is to be outstanding.

The  Central  Bank  resolution  further  provides  that  the  requirements  described  above  do  not  apply  to  financing
transactions  involving  multilateral  or  official  organizations  such  as  the  World  Bank,  the  InterAmerican
Development Bank or the Japan Bank for International Cooperation.  The Central Bank circular implementing this
resolution  provides,  among  other  things,  that  the  account  referred  to  in  the  first  bullet  point  above  must  be  an
account  opened  in  a  federal  financial  institution,  which  is  to  hold  such  funds  until  released  for  the  purpose  of
refinancing  outstanding  obligations  of  the  issuer.    The  circular  further  provides  that  the  account  described  in  the
second bullet point above must be an escrow account to be opened in a federal financial institution and to secure the
payment of principal and interest on the external debt.

Our external credit transactions are also subject to the approval of the National Treasury Secretariat and the Central
Bank,  which,  after  reviewing  the  financial  terms  and  conditions  of  the  transaction,  will  issue  an  approval  for  the
closing of the foreign exchange transaction relating to the entry of the funds into Brazil and, following such entry
and  at  our  request,  an  electronic  certificate  of  registration  through  which  all  scheduled  payments  of  principal,
interest and expenses will be remitted by us.  The electronic certificate of registration grants the borrower access to
the market for foreign exchange.

Finally,  our  external  credit  transactions  are  also  subject  to  the  prior  approval  of  the  Secretariat  of  Finance  of  the
State.

Lending Limits of Brazilian Financial Institutions

The National Monetary Council resolutions limit the amount that Brazilian financial institutions may lend to public
sector companies, such as us.  Financing of projects which are put up for international bid are excluded from these
limits.

Conselho Estadual de Saneamento—Conesan

State  law  regulates  the  provision  of  sanitation  services  and  establishes  rules  for  the  planning  of  sanitation-related
public  works  in  the  state  of  São  Paulo.    The  State  plan  for  public  sanitation  services  must  integrate  institutional,
technological, financial and administrative resources to ensure that a healthy environment is created for inhabitants
of the state of São Paulo.  The State plan must also assist in developing and organizing the sanitation sector in the
state of São Paulo.

Pursuant to State law, the State’s sanitation policy is implemented by the State Sanitation System (Sistema Estadual
de Saneamento).  The State Sanitation Fund (Fundo Estadual de Saneamento) collects funds and manages resources
to fund the programs approved in the sanitation plan.

48

The State Sanitation Council (Conselho Estadual de Saneamento) must approve proposals related to the sanitation
plan and prepare an annual report regarding environmental health issues confronting the State.  The State Sanitation
Council establishes protocols for the development of investment programs approved by the State Sanitation System
and resolves disputes related to the State Sanitation System’s implementation of the sanitation plan.

Property, Plant and Equipment

Our  principal  properties  consist  of  reservoirs,  water  treatment  facilities,  water  distribution  networks  consisting  of
water  pipes,  water  mains,  water  connections  and  water  meters,  sewage  treatment  facilities,  and  sewage  collection
networks  consisting  of  sewer  lines  and  sewage  connections.    As  of  December  31,  2004,  we  owned  195  water
treatment  facilities  and  58,073  kilometers  of  water  pipes  and  mains,  431  sewage  treatment  facilities  and  36,435
kilometers of sewer lines, as well as 15 water quality laboratories.

We  own  our  headquarters  building  and  all  other  major  administrative  buildings.    We  have  pledged  some  of  our
properties  as  collateral  to  the  Federal  Government  in  connection  with  a  long-term  financing  transaction  we  have
entered into with the World Bank that the Federal Government has guaranteed.

As of December 31, 2004 the total net book value of our property, plant and equipment was R$14,040.9 million.

All of our material properties are located in the state of São Paulo.

Environmental Matters

Our  water  and  sewage  operations  are  subject  to  stringent  Brazilian  federal,  state  and  local  laws  and  regulations
relating to the protection of the environment as described under “Government Regulation” below.

In  the  state  of  São  Paulo,  the  Environmental  Sanitation  Technology  Company  (Companhia  de  Tecnologia  de
Saneamento  Ambiental—CETESB)  is  responsible  for  pollution  control  pursuant  to  State  Law  No. 997  of  May  31,
1976.  In particular, the construction and operation of water and sewage treatment facilities, as well as the release of
effluents  and  final  disposal  of  the  sludge  generated  as  a  result  of  the  water  and  sewage  treatment  process,  must
comply with environmental standards established by State environmental laws, such as State Decree  No. 8,468  of
September 8, 1976, as amended.

Non-compliance with environmental laws and regulations can lead to the imposition of criminal and administrative
penalties, in addition to civil liability which may arise as a result of environmental damages.  Pursuant to Brazilian
Federal  Law  No. 9,605  of  February  12,  1998,  individuals  (including  but  not  limited  to  the  directors,  officers  and
managers of legal entities) may be penalized with imprisonment or other restrictions on personal rights for violations
of  environmental  rules  and  regulations,  and  legal  entities  may  be  penalized  with  fines,  restrictions  on  rights,
including, among other things, rights to be granted tax benefits and to enter into contracts with public entities, and
mandatory rendering of services in the public benefit.  At  the  administrative  level, penalties range from  warnings
and fines to partial or total suspension of corporate activities, and may also include the forfeiture of, or restriction
on,  tax  incentives,  and  the  cancellation  or  interruption  of  participation  in  credit  facilities  granted  by  government
banks, as well as a prohibition on contracting with entities of the public sector.

Our procedure for constructing and operating water and sewage facilities involves the mandatory compliance with
environmental legal requirements.  Firstly, for those projects which have a significant environmental impact, studies
are prepared by outside experts who make recommendations on measures designed to minimize the environmental
consequences  of  a  project.    The  environmental  impact  report  is  then  submitted  to  governmental  authorities  for
analysis  and  approval.    Once  the  environmental  impact  assessment  is  approved,  the  project  goes  through  a  three-
stage licensing process, which includes licenses:

•

•

Previous license—to define the exact location and scope of work;

Installation license—to begin construction; and

49

•

Operation license—to operate the facility.

In order to obtain the environmental licensing of those undertakings that have a significant environmental impact,
environmental agencies may impose on us an obligation to establish a nature conservation area.  In order to fulfill
such obligation, we are required by environmental regulations to spend not less than 0.5% of the total cost of the
relevant  undertaking  for  that  purpose.    We  also  have  a  policy  of  implementing  programs  to  encourage  water
conservation in order to minimize the environmental impact of our ongoing operations.

In  order  to  improve  our  compliance  with  environmental  regulations,  since  1995,  we  have  maintained  a  division
responsible  for  developing  environmental  impact  studies  and  programs.    It  is  also  our  policy  to  implement  water
conservation programs in order to minimize the impact of our operations on our water supply.  We believe that we
are in material compliance with all relevant environmental laws and regulations.

Although our environmental compliance costs have not been substantial to date, we believe these costs will increase
as water and sewage treatment capacity increases.  The amount and timing of future expenditures required to comply
therewith could substantially increase from current levels.

Insurance

We  maintain  insurance  covering,  among  other  things,  fire  or  other  damage  to  our  property,  office  buildings  and
third-party liability.  We currently obtain our insurance policies through public bids involving major Brazilian and
international  insurance  companies  in  Brazil.    As of  December 31, 2004,  we  had paid  a  total  aggregate  amount  of
R$6.8 million  in  premiums,  covering  approximately  R$984.8 million.    We  do  not  have  insurance  coverage  for
business interruption risk because we do not believe that the high premiums for such insurance are justified by the
low  risk  of  major  interruption.    In  addition,  we  do  not  have  insurance  coverage  for  liabilities  arising  from  water
contamination or other problems involving our water supply to customers.  We believe that we maintain insurance at
levels customary in Brazil for the type of business in which we are engaged.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The following management’s discussion and analysis of financial condition and results of operations should be read
in  conjunction  with  our  audited  financial  statements  included  in  this  annual  report.    This  annual  report  contains
forward-looking statements that involve risks and uncertainties.  Our actual results may differ materially from those
discussed  in  the  forward-looking  statements as  a  result  of  various  factors,  including,  without  limitation,  those  set
forth in “Risk Factors.”

The financial statements in this annual report have been prepared in accordance with the Brazilian Corporate Law
Method, which differs in certain significant respects from U.S. GAAP.  We have included a discussion below of the
material  differences  between  the  Brazilian  Corporate  Law  Method  and  U.S. GAAP  related  to  each  critical
accounting  policy  in  our  audited  financial  statements.    For  additional  information  regarding  other  differences
between the Brazilian Corporate Law Method and U.S. GAAP, please see note 23 to our financial statements.

In  the  following discussion,  references  to  increases  or  decreases  in  any  period  are  made  by  comparison  with  the
corresponding prior period, except as the context otherwise indicates.

Overview

We operate water and sewage systems in the state of São Paulo, including in the City of São Paulo, Brazil’s largest
city, and in more than one-half of the other municipalities in the state of São Paulo.  We also make wholesale sales
of water to six additional municipalities in which we do not operate water systems.

The São Paulo Metropolitan Region, which includes the City of São Paulo, is our most important service territory.
With a population of approximately 19.0 million, the São Paulo Metropolitan Region accounted for approximately
75.8%,  75.9%  and  74.5%  of  our  gross  revenue  from  sales  and  services  in  2002,  2003  and  2004,  respectively.
Approximately 73.4% of the property, plant and equipment reflected on our balance sheet as of December 31, 2004
is located in this region.  In an effort to respond to demand in the São Paulo Metropolitan Region and because the
region represents the principal opportunity to increase our net revenue from sales and services, we have dedicated a
major  portion  of  our  capital  expenditure  program  to  expand  the  water  and  sewage  systems  and  to  increase  and
protect water sources in this region.  Our capital expenditure program is our most significant liquidity and capital
resource requirement.

Factors Affecting Our Results of Operations

Our  results  of  operations  and  financial  condition  are  generally  affected  by  our  ability  to  raise  tariffs,  general
economic conditions in Brazil and, in recent periods, meteorological conditions. In 2004, results of operations and
financial condition were also significantly affected by an increase in bad debt expenses net of recoveries, increases
in electricity costs, and increases in payments for outside services.

Effects of Tariff Increases

Our results of operations and financial condition are highly dependent upon our ability to set and collect adequate
tariffs for our water and sewage services.  Although we generally have broad power to establish tariffs within our
service territories, this power is, in practice, subject to limits due to, among other factors, the following:

•

•

•

political considerations arising from our status as a State-controlled company;

anti-inflation measures promulgated by the Federal Government from time to time; and

federal laws that in some circumstances limit to 12.0% per year the return on the assets of some of
our concessions.

51

Tariffs have often failed to keep up with inflation during periods of high inflation in the past.  During the past few
years, we generally have been able to raise tariffs in line with increases in cost of sales and services and operating
expenses and to support our liquidity and capital resource requirements.  In 2000, we did not raise tariffs due to the
State policy for that year of not increasing tariffs for many public services.  In June 2001, however, we increased our
average tariff by approximately 13.1%, which was broadly in line with prevailing inflation rates in Brazil since mid-
1999  as  measured  by  the  consumer  price  index,  and  in  August  2002,  we  increased  our  tariffs  by  approximately
8.2%.    In  August  2003,  we  increased  our  tariffs  for  water  and  sewage  services  by  approximately  18.9%,  and  in
August 2004 we raised our tariffs for water and sewage services by approximately 6.8%.  Since August 2003, our
tariffs have been determined using a transparent formula which accounts for inflation, covers our operating costs and
other  expenses  and  provides  for  a  return  on  investment.    We  are  currently  evaluating  and  considering  a  potential
revision to our tariff structure in order to improve our return on investment.  Tariffs have historically been adjusted
once  a  year  and  for  periods  of  at  least  12  months.    The  following  table  sets  forth,  for  the  periods  indicated,  the
percentage increase of our tariffs, as compared to three inflation indices:

Effects of Brazilian Economic Conditions

As a company with all of its operations in Brazil, our results of operations and financial condition are affected by
general  economic  conditions  in  Brazil,  particularly  by  currency  exchange  rate  movements,  inflation  rates  and
interest rate levels.  For example, the general performance of the Brazilian economy affects demand for water and
sewer  services,  and  inflation  affects  our  costs  and  our  margins.    The  Brazilian  economic  environment  has  been
characterized by significant variations in economic growth rates.

General Economic Conditions.  In 2002, several negative economic factors adversely affected consumer confidence
levels  in  Brazil.    Prior  to  and  subsequent  to  the  presidential  elections  in  November  2002,  there  was  substantial
uncertainty  relating  to  Brazil’s  own  political  and  economic  future.    Other  negative  economic  factors  in  2002
included  the  continued  economic  and  political  uncertainties  in  Argentina  and  in  Venezuela,  concerns  over  the
impact  of  the  conflict  in  the  Persian  Gulf  and  its  effects  on  the  price  of  oil  products  and  the  global  economic
slowdown.  The sharp devaluation of the real in the second half of 2002 heightened concerns over a possible return
to high inflation.  The monetary authorities under both the former and new presidential administrations acted quickly
to increase interest rates through the end of the year, which severely restricted credit available in the economy and
consequently affected growth.  In 2002, real gross domestic product in Brazil grew 1.9% and inflation was 25.3%, as
measured  by  the  IGP-M.    The  real  depreciated  by  34.3%  against  the  U.S. dollar  during  2002.    Interest  rates
increased,  as  the  Central  Bank  increased  the  base  interest  rate  repeatedly,  from  19.0%  early  in  2002  to  25.0%  at
year-end.

In 2003, the new administration largely continued the macroeconomic policies of the previous administration.  The
real  appreciated  by  22.3%  against  the  U.S. dollar  in  2003  to  R$2.8892  per  U.S.$1.00  as  of  December  31,  2003.
Inflation for 2003, as measured by the IGP-M, was 8.7%.  However, real gross domestic product decreased by 0.2%
during  2003  largely  because  the  very  high  interest  rates  that  prevailed  at  the  beginning  of  2003  also  constrained
economic growth.  The Brazilian economy showed signs of improvement in the third and fourth quarters of 2003
that  continued  through  2004.    During  2004  real  gross  domestic  product  grew  by  5.2%,  inflation  was  12.4%  as

52

measured by the IGP-M and the real appreciated 8.8% against the U.S. dollar as the real/U.S. dollar exchange rate
decreased to 2.6544 reais as of December 31, 2004.

Interest Rates.  Interest rate levels in Brazil are closely linked to exchange rate movements and inflation rates.  High
domestic interest rates result in increases in our financial expenses and also negatively affect our ability to obtain
financing, on a cost-effective basis, in domestic capital and lending markets.  As a result, we may continue to require
substantial  amounts  of  foreign  currency-denominated  debt  in  order  to  satisfy  our  liquidity  and  capital  resource
requirements, which increases our exposure to exchange rate movements as discussed below.

The Central Bank increased the base interest rate to 26.5% on February 19, 2003 and decreased it to 16.0% on April
14, 2004.  The Central Bank increased the base interest rate to 17.75% on December 15, 2004.  During the first four
months of 2005, the Central Bank continued to raise the base interest rate, which reached 19.5% on April 20, 2005.

We  have  not  utilized  any  derivative  financial  instruments,  or  any  hedging  instruments  to  mitigate  interest  rate
fluctuations.    We do, however,  continually  monitor  market  interest  rates  in  order  to  evaluate  the  possible  need  to
refinance our debt

Inflation.    Inflation  affects  our  financial  performance  by  increasing  our  costs  of  services  rendered  and  operating
expenses.  In addition, all of our real-denominated debt is indexed to take into account the effects of inflation.  Most
of our real-denominated debt provides for inflation-based increases in the respective principal amounts of that debt,
which  increases  are  determined  by  reference  to  the  daily  government  interest  rate  (Taxa  Referencial-TR)  plus  an
agreed margin.  We cannot assure you that we will be able, in future periods, to increase tariffs to offset, in full or in
part, the effects of inflation.

Currency  Exchange  Rates.    We  had  total  foreign  currency-denominated  indebtedness  of  R$2,680.9 million  as  of
December 31, 2004.  In the event of further significant devaluations of the real in relation to the U.S. dollar or other
currencies, the cost of servicing our foreign currency-denominated obligations would increase as measured in reais,
particularly as our tariff and other revenue are based solely in reais.  In addition, any significant devaluation of the
real will increase our financial expenses as a result of foreign exchange losses that we must record.  For example,
the  34.3%  devaluation  of  the  real  in  2002  increased  our  financial  expenses  and  negatively  affected  our  overall
results of operations for that year.  In contrast, in 2003, the real appreciated 22.3% against the U.S. dollar, which
resulted in a foreign exchange gain of R$540.6 million.  The 8.8% of the real against the U.S. dollar in 2004 led to a
foreign exchange gain of R$179.7 million.

The following table shows the devaluation (appreciation) of the real against the U.S. dollar, the period-end exchange
rates and average exchange rates for the periods indicated:

Effects of Drought

Much of Brazil experienced a prolonged and severe drought during 2000 and 2001, although historically droughts
have not impacted all of our water supply systems equally.  During this period, the São Paulo Metropolitan Region,
in particular, faced its worst drought in 65 years.  As a result, from mid-June to mid-September in 2000, we rationed
water  in  the  south  of  the  São  Paulo  Metropolitan  Region,  affecting  approximately  3.5 million  people,  or
approximately  20%  of  the  total  population  of  this  region.    Under  this  rationing,  water  was  made  available  to  our
customers  for  only  two out of  every  three days.    During  this  period  of  rationing,  we  also  reduced  our  total  water
production  by  approximately  8%.    From  April  2001  through  January  2002,  we  rationed  water  in  the  west  of  the
São Paulo  Metropolitan  Region,  affecting  approximately  300,000  people.    Under  this  rationing,  water  was  made
available to these 300,000 customers for only 40 out of every 78 hours.  Throughout 2003 rain levels were below
average resulting in a weak replenishment of our reservoirs, particularly in the Cantareira System, the largest water
supply system in the São Paulo Metropolitan Region.  From October to December 2003, we rationed water on the
western  part  of  the  São  Paulo  Metropolitan  Region,  served  by  the  Alto  Cotia  System,  affecting  approximately
450,000 people, or approximately 2% of the region’s population.  Under this rationing, water was available to those
people for three days, followed by two days of rationing.  During this period our total water production volume was
reduced by 0.8%.  As a result of the drought, our revenue declined as our volume of water billed decreased, and our
costs increased because of required expenditures to protect and develop water sources and to preserve water quality.
The impact that droughts have may vary across our different systems, which may allow us to mitigate the effects of
any  particular  drought.    The  effects  of  the  drought  continued  to  impact  our  systems  through  2004.    In  order  to
minimize the effects of this drought we implemented a water usage reduction bonus program.  Due to this program
and  the  return  to  normal  rainfall  levels  that  occurred  throughout  2004  and  early  2005,  the  conditions  of  our
reservoirs have improved.

Effects of the Water Usage Reduction Bonus Program

In  order  to  encourage  customers  to  use  less water  in drought  conditions,  in 2004 we  instituted  a  “bonus”  system,
rewarding customers who reduced their water consumption by specified amounts.  The “bonus” was shown on each
customer’s bill as a discount, and was calculated based on the customer’s water usage each month, and applied to
decrease the amount payable by that customer.

This water usage reduction program took effect on March 15, 2004 and ended on September 15, 2004, and had the
following effects:

•

•

•

customers  reduced  their  overall  water  usage,  leading  to  lower  revenues  from  lower  volumes  of
water and sewage services;

we discounted the amounts payable by customers who successfully lowered their water usage; and

many  customers,  by  reducing  their  water  usage,  shifted  their  households  into  a  lower  tariff
category.

Our results for 2004 reflect the impact of these effects, all of which lowered our revenue from March 15, 2004 to
September 15,  2004,  thus  affecting  bills  sent  out  through  October.    In  2004,  the  volume  of  water  and  sewage
invoiced  decreased  by  1.4%,  and  our  revenue  from  water  and  sewage  services  provided  to  the  São  Paulo
Metropolitan Region decreased by R$74.1 million, as a result of our water reduction program.  This reduction was
offset in part by the positive impact of tariff readjustments.

Critical Accounting Policies, Practices and Estimates

Critical  accounting  policies  and  practices  are  those  that  are  both  (1)  important  to  the  portrayal  of  our  financial
condition and results of operations and (2) require management’s most difficult, subjective or complex judgments,

54

often  as  a  result  of  the  need  to  make  estimates  about  the  effect  of  matters  that  are  inherently  uncertain.    As  the
number  of  variables  and  assumptions  affecting  the  possible  future  resolution  of  the  uncertainties  increase,  those
judgments  become  even  more  subjective  and  complex.    In  order  to  provide  an  understanding  about  how  our
management  forms  its  judgments  about  future  events,  including  the  variables  and  assumptions  underlying  the
estimates,  and  the  sensitivity  of  those  judgments  to  different  circumstances,  we  have  identified  the  critical
accounting policies and practices discussed below.

Our management discussion and analysis of financial condition and results of operations are based upon our primary
financial  statements,  which  have  been  prepared  in  accordance  with  the  Brazilian  Corporate  Law  Method  which
differs in significant respects from U.S. GAAP.  We have included a discussion on material differences between the
Brazilian Corporate Law Method and U.S. GAAP related to each critical accounting policy in our audited financial
statements.

Allowance for Doubtful Accounts

We record allowance for doubtful accounts in an amount that our management considers sufficient to cover probable
losses,  based  on  an  analysis  of  customer  accounts  receivable,  taking  into  consideration  the  expected  recovery  in
different categories of customers.  We record an allowance for doubtful accounts for balances receivable in excess
of R$5,000 and overdue for more than 360 days, and for balances receivable in excess of R$30,000 and overdue for
more than 360 days as to which we have commenced judicial collection proceedings.  Accounts receivable balances
under R$5,000 and overdue for more than 180 days are written off as a direct charge to income.

Provisions  for  the  allowance  for  doubtful  accounts  are  included  in  selling  expenses,  net  of  recoveries.    The  net
charge to this allowance was R$241.6 million in 2004, R$37.6 million in 2003 and R$162.9 million in 2002.

Our  methodology  for  determining  the  allowance  for  doubtful  accounts  receivable  requires  significant  estimates,
considering  a  number  of  factors  including  historical  collection  experience,  current  economic  trends,  estimates  of
forecast  write-offs,  the  aging  of  the  accounts  receivable  portfolio  and  other  factors.    While  we  believe  that  the
estimates we use are reasonable, actual results could differ from those estimates.

In addition, we have substantial assets consisting of amounts owed by the State.  These amounts consist primarily of
accounts receivable for services, reimbursement for pensions paid and amounts due under our December 2001 and
March 2004 agreement with the State.  See “Item 7.  Major Shareholders and Related Party Transactions— Related
Party Transactions”  We do not reserve against any of these amounts owed by the State due to the following factors:

•

•

we do not expect to incur losses from these accounts receivable; and

we entered into agreements in September 1997, December 2001 and March 2004 under which the
State has committed to settle the outstanding amounts due to us described in these agreements by
applying dividends declared by us to the remaining balance of the accounts receivable owed by the
State or its controlled entities.

As  of  December  31,  2004,  the  amounts  owed  to  us  by  the  State  for  the  provision  of  water  and  sewage  services
included  R$245.6 million  which was  considered overdue  as  of  February  29,  2004.   This amount does  not  include
R$105.5 million which the State agreed to apply in respect of dividends payable to it as part of its agreement with
us.  As of December 31, 2004 the State owed us an additional R$48.5 million in accounts receivable related to the
provision of water and sewage services rendered from February 2004.  With respect to reimbursement for pensions
paid on behalf of the State, the State owed us R$576.3 million as of December 31, 2004 (R$320.6 million of which
was acknowledged by the State in an agreement with us subject to a further audit which has not yet occurred).  We
expect  amounts  owed  to  us  by  the  State  for  water  and  sewage  services  and  reimbursements  for  pensions  paid  to
increase in the future.  We have not established any provisions for any amounts due to us by the State.  If the State
does  not  pay  the  amounts  it  owes  to  us,  our  cash  flows,  results  of  operations  and  financial  condition  will  be
impacted.

55

For  U.S. GAAP  purposes,  the  amounts  receivable  from  the  State  for  pensions  paid  is  not  recorded  as  accounts
receivable,  but  rather  is  included  as  part  of  our  estimated  pension  and  other  post-retirement  obligations.    Only
amounts effectively reimbursed by the State are presented as additional paid-in capital.  No additional differences
have been identified between accounting policies for accounts receivable and allowance for doubtful accounts under
the Brazilian Corporate Law Method and U.S. GAAP.

Indemnities Receivable

Indemnities receivable is a long-term asset representing amounts receivable from the Municipalities of Diadema and
Mauá  as  indemnification  for  the  unilateral  withdrawal  by  those  authorities  of  our  water  and  sewage  service
concessions in 1995.  As of December 31, 2004, this asset amounted to R$148.8 million.

Under  our  concession  agreements  we  invested  in  the  construction  of  water  and  sewage  systems  in  these
municipalities to  meet our concession service commitments.  Upon the unilateral  termination  of  the  Diadema  and
Mauá  concessions,  our  assets  were  impounded  by  the  municipal  authorities,  which  took  on  the  responsibility  of
providing water and sewage services in these areas.  At that time, we reclassified our property, plant and equipment
balances  relating  to  the  impounded  assets  to  long-term  assets  (indemnities  receivable)  and  recorded  impairment
charges  to  reduce  the  carrying  value  of  the  assets  to  the  estimated  recoverable  amounts  for  which  we  had
contractually agreed as fair compensation with the relevant authorities.

Our  rights  to  the  recovery  of  these  amounts  are  being  disputed  by  the  municipalities  and  no  amounts  have  been
received to date.  Based on the advice of legal counsel, we continue to believe that we have the right to receive such
amounts  and  we  continue  to  monitor  the  status  of  the  legal  proceedings.    However,  the  ultimate  amounts  to  be
received, if any, will most likely be subject to a final court decision.  As such, actual amounts received could differ
from those recorded.

With  respect  to  Mauá,  a  decision  has  been  issued  by  the  lower  court  requiring  Mauá  to  pay  us  the  amount  of
R$153.2 million as compensation for the loss of profits.  This decision is subject to appeal.  For more information,
see “Item 8.  Financial Information—Legal Proceedings.”

No  differences  have  been  identified  between  accounting  policies  on  compensation  for  concession  termination
adopted under the Brazilian Corporate Law Method and U.S. GAAP.

Property, Plant and Equipment

Valuation of Long-Lived Assets.  We review long-lived assets, primarily buildings, water and sewage system assets
and acquired concession assets to be held and used in our business, for the purpose of determining and measuring
impairment on a recurring basis or when events or changes in circumstances indicate that the carrying value of an
asset or group of assets may not be recoverable.  Under the Brazilian Corporate Law Method, we evaluate possible
impairment  by  determining  whether  projected  future  operating  income  is  sufficient  to  absorb  the  depreciation  or
amortization of long-lived assets, within the context of the balance sheet as a whole.

Studies  supporting  the  write-offs  for  obsolescence  and  abandonment  of  projects  are  conducted  in  the  accounting
period of the write-offs based on undiscounted cash flow projections, and approved by our Board of Directors.  We
monitor the carrying value of our property, plant and equipment on an on-going basis and adjust the net book value
to assure future projected operations will be sufficient to recover the carrying value of the assets.  Depreciation is
provided using the straight-line method based on the estimated useful lives of the underlying assets.  When possible,
depreciation  rates  are  adjusted  to  take  account  of  changes  in  estimated  prospective  depreciable  lives  as  assets  are
replaced.

U.S. GAAP  Statement  of  Financial  Accounting  Standards,  or  SFAS,  No. 144,  “Accounting  for  the  Impairment  of
Long-lived Assets,” requires companies to periodically evaluate the carrying value of  long-lived assets  to be held
and  used,  and  for  long-lived  assets  to  be  disposed  of,  when  events  and  circumstances  warrant  such  a  review.
Companies are required to identify the smallest unit, or group, of assets at which cash flows generated by the group
can be measured.  The projected undiscounted cash flows from each such asset group is compared to its carrying

56

value.  For those assets for which the projected cash flows are not sufficient to recover the carrying values, a loss is
recognized to the extent that the carrying value exceeds the fair market value of the assets.

In evaluating impairment of our long-lived assets, we make significant assumptions and estimates regarding matters
that are inherently uncertain, including projections of future operating income and cash flows, future growth rates,
and the remaining useful lives of the assets, among others.  In addition, projections are computed over an extended
period of time, which subjects those assumptions and estimates to an even larger degree of uncertainty.  While we
believe  that  the  estimates  we  use  are  reasonable,  the  use  of  different  assumptions  could  materially  affect  our
valuations.

No adjustments have been included in the reconciliation from the Brazilian Corporate Law Method to U.S. GAAP to
take  account  of  differences  between  the  measurement  criteria,  because  no  impairment  provisions  were  required
based on our analysis of cash flows.  Losses on the write-off of property, plant and equipment arose primarily from
adjustments upon withdrawal of concession assets, construction-in-progress projects which were deemed no longer
to be economically feasible and obsolescence write-offs.

Depreciation  of  Property,  Plant  and  Equipment.    Depreciation  of  our  property,  plant  and  equipment,  primarily
buildings, water and sewage service and other assets acquired, is provided using the straight-line method based on
the  estimated  useful  lives  of  the  underlying  assets,  which  generally  do  not  exceed  the  contractual  terms  of  our
concession agreements.

While  we  believe  that  our  estimates  of  current  remaining  estimated  lives  is  reasonable,  the  use  of  different
assumptions and estimates and changes in future circumstances, could affect the remaining useful lives of our asset,
which could have a significant impact on our results of operations in the future.

Loss Contingencies

We are a party to a number  of  legal proceedings  involving  significant  monetary  claims.    These  legal  proceedings
include,  among  others,  tax,  labor,  civil,  environmental,  condemnation  and  other  proceedings.    We  accrue  for
probable losses resulting from these claims and proceedings when we determine that the likelihood that a loss has
occurred is probable and the amount of such loss can be reasonably estimated.  As such, we are required to make
judgments regarding future events for which we often seek the advice of legal counsel.  As a result of the significant
judgment required in assessing and estimating these loss contingencies, actual losses realized in future periods could
differ significantly from our estimates.

No differences have been identified between accounting policies on loss contingencies adopted under the Brazilian
Corporate Law Method and U.S. GAAP.

Pension Plans

Plan  G1.    We  sponsor  a  funded  defined-benefit  pension  and  benefits  fund  (“Plan  G1”),  which  is  operated  and
administered by SABESPREV—Fundação SABESP de Seguridade Social.

Under the Brazilian Corporate Law Method, prior to January 1, 2002, we recorded pension expense on an accrual
basis based on our contributions to the Plan.  Effective January 1, 2002, in accordance with the issuance of a new
accounting  standard,  we  began  accounting  for  our  actuarial  obligation  under  Plan  G1.    As  permitted  under  this
standard,  we  are  amortizing  the  transition  liability  related  to  the  actuarial  value  of  our  obligation  at  the  date  of
adoption of the new standard over a period of five years, which is recorded in our  statements  of  operations  as  an
extraordinary  item,  net  of  the  related  tax  impacts.    For  2004,  pension  costs  charged  to  income  totaled
R$86.9 million, of which R$35.1 million (net of tax effects totaling R$18.1 million) was presented as “extraordinary
item  net  of  income  tax  and  social  contribution.”    The  remaining  R$51.8 million  was  charged  to  cost  of  services
rendered, general and administrative expenses and selling expenses.  Based on independent actuarial reports, as of
December 31, 2004, our obligation under Plan G1 was R$328.6 million.  See note 12 to our financial statements.

57

Under U.S. GAAP, we had already adopted the provisions of SFAS No. 87, “Employers’ Accounting for Pensions”
prior to 2002, which requires that we recognize an actuarial liability for pension benefits under Plan G1.  While the
actuarial assumptions used for U.S. GAAP are the same as those used in determining the actuarial liability under the
Brazilian Corporate Law Method, pension costs and obligations under U.S. GAAP and the Brazilian Corporate Law
Method are not the same, mainly due to differences related to the first year of application, the amortization of the
initial  transition  obligation,  amortization  periods  for  other  actuarial  gains  and  losses,  and  actuarial  calculation
methods, among others.  See note 23 to our financial statements.

We  are  currently  evaluating  the  possible  introduction  of  a  defined  contribution  plan  for  new  employees  and
providing exiting employees an option to switch to this new plan from Plan G1.

Plan G0.  Pursuant to a law enacted by the State, some of its employees who provided service to us prior to May
1974 and retired as employees of ours acquired a legal right to receive supplemental pension payments (which rights
are referred to as “Plan G0”).  These amounts are paid by us on behalf of the State and are claimed as reimbursement
from the State.  As such, no pension expense related to Plan G0 is recorded and no future obligations are recorded
under the Brazilian Corporate Law Method.

Consistent with the guidance in SEC Staff Accounting Bulletin Topic 5-T (“SAB No. 5-T”), under U.S. GAAP, we
recognize the costs and obligations associated with Plan G0 supplemental pension benefits on a “push-down basis,”
as  we  are  the  recipients  of  the  benefits  of  the  employee  service  for  which  the  supplemental  pension  benefits  are
made.  The Plan G0 benefit obligation and expenses are accounted for in accordance with SFAS No. 87.  Eventual
amounts received as reimbursement from the State, if any, are treated as additional paid-in-capital.  As such, Plan
G0 is considered unfunded for purposes of U.S. GAAP.  See note 23 to our financial statements.

Assumptions.  Accounting for these pension benefits under the Brazilian Corporate Law Method and U.S. GAAP,
requires  an  extensive  use  of  assumptions,  including  those  related  to  the  inflation  adjusted  discount  rate,  expected
return on plan assets, the expected rate of future compensation increases received by our employees, mortality rates,
and  turnover.    We review  each  assumption  annually, with  the assistance  of our  actuarial  consultant  who  provides
guidance in establishing the assumptions.  The assumptions are selected to represent the weighted average expected
experience over time and may differ in any one year from actual experience due to changes in the capital markets
and the overall economy, regulatory events, judicial rulings, and higher or lower actual rates of withdrawal, turnover
or  mortality  among  our  participating  employees.    While  we  believe  that  our  assumptions  used  are  appropriate,
differences  in  actual  experience  or  changes  in  assumptions  could  affect  the  amount  of  pension  expense  that  we
recognize.

The present value of our pension obligations was based on a discount rate of 12.32%, 12.32% and 15.56% for 2004,
2003 and 2002, respectively.  Our pension obligation and expense increases as the discount rate is reduced.

Our expected return on assets for Plan G1 is determined by evaluating the asset class return expectations with our
advisors, as well as actual, long-term historical results of our asset returns.  For 2004, we used an expected rate of
return  on  assets  assumption  of  12.06%,  which  is  expected  to  remain  the  same  for  2005.    The  expected  return  on
assets assumption is based on a targeted allocation of investments in accordance with the investment strategies of the
plans.  We believe that this targeted allocation will, on average, approximate actual long-term asset allocation.

Certain Transactions with Controlling Shareholder

Reimbursement Due from the State.  Reimbursement due from the State for pensions paid represent supplementary
pensions (Plan G0) that we pay, on behalf of the State, to former employees of the State-owned companies which
merged to form a company.  These amounts are reimbursed to us by the State, as primary obligor.  However, these
amounts have been outstanding for a long period.  We account for these as long-term assets, and we do not reserve
against such accounts receivable as we expect to recover these amounts and loss is not considered probable.

Accounts Receivable from the State for Water and Sewage Service Provided.  Certain of these accounts receivable
have been overdue for a long period.  We account for these as long-term assets, and we do not reserve against such
accounts receivable as we fully expect to recover these amounts and loss is not considered probable.

58

Use of Certain Assets Owned by the State.  We currently use certain reservoirs in the Alto Tietê System and the
Billings  and Guarapiranga  reservoirs  which  are  owned  indirectly  by  the  State.    We  currently  do  not  pay  any  fees
with respect to the use of these reservoirs.  However, we are responsible for maintaining and meeting the operating
costs of these reservoirs.  If these facilities had not been made available for our use, we would have had to obtain
water  from  more  distant  sources,  which  would  be  more  costly.    The  State  does  not  incur  operating  costs  on  our
behalf.

The  arrangement  not  to  pay  any  fees  to  the  State  for  the  use  of  certain  reservoirs  of  the  Alto  Tietê  System  is
addressed by a number of formal agreements first entered into on March 31, 1992 and on April 24, 1997 and later
amended on March 16, 2000 and on November 21, 2001, respectively.  As part of the arrangement, we agreed to
fund  100.0%  of  the  estimated  costs  of  the  1992  agreement  (equal  to  R$27.8 million)  and  75.0%  of  the  1997
agreement (equal to R$63.4 million) which was already disbursed, and the Government of the State of São Paulo,
through the State Department of Water and Energy, agreed to fund approximately 25.0% of the estimated costs of
the  1997  agreement  (equal  to  R$21.1 million),  to  construct  ducts,  tunnels  and  other  facilities  to  interconnect  the
Tietê  River  with  the  Biritiba  and  Jundiaí  reservoirs  and  other  bodies  of  water  in  exchange  for  our  use  of  the
reservoirs during a 30-year period.  The amendments to the 1997 agreement increased our obligations under such
agreement by R$5.9 million.

We have the right to draw water and release emissions in the reservoirs in the Alto Tietê system during a 30-year
period which began in 1997.  We capitalize our expenditures on the facilities we construct.  The project subject to
the  1992  agreement  was  concluded  and  the  assets  entered  operations  in  1994.    The  project  subject  to  the  1997
contract became operational in 2002 and is being depreciated on a straight-line basis through 2027.

The arrangement for use of the Billings and Guarapiranga reservoirs is provided for through a grant issued by the
Department  of  Water  and  Energy.    We  have  a  right  to  use  these  reservoirs  so  long  as  we  remain  responsible  for
maintaining and meeting their operating costs.

Net  revenue  from  sales  and  services  for  2004  increased  by  R$266.3 million,  or  6.5%,  to  R$4,397.1 million  from
R$4,130.8 million for 2003.

Net revenue from sales and services relating to water services for 2004 increased by R$122.8 million, or 5.1%, to
R$2,541.0 million  from  R$2,418.2 million  for  2003.    This  increase  was  mainly  due  to  the  August  2003  tariff
increase of 18.9% (and, to a lesser extent, the August 2004 tariff increase of 6.8%) and the increase in revenue due

59

to our  shift  from  wholesale  to  direct distribution  and  improvements  in billing  and  collection  for water  services  in
São Bernardo do Campo.  This increase was offset by a 4.1% decrease in volume of water distributed and invoiced
in  2004,  resulting  from  our  campaign  to  reduce  water  consumption  throughout  the  period,  together  with,  from
March 15,  2004,  the  effects  of  the  usage  reduction  discount  plan  which,  as  discussed  above,  lowered  usage,
discounted the bill of consumers who lowered their usage, and shifted some households into lower tariff categories.
Total discounts given to consumers under this plan amounted to R$74.1 million, which would otherwise have been
recognized as revenue.  Although the usage reduction discount plan ended in September 2004, the impact of the plan
on our results of operations, including lowered usage of water by consumers, continued throughout the year.  By the
end of the year, however, the impact of the plan had begun to abate, and usage levels started to increase.

Net revenue from sales and services relating to sewage services for 2004 increased by R$143.6 million, or 8.4%, to
R$1,856.1 million  from  R$1,712.5 million  for  2003.    Volumes  of  sewage  increased  by  2.8%,  rising  in  the  fourth
quarter  as  the  impact  of  our  water  usage  reduction  discount  plan  abated,  while  tariffs  increased  by  6.8%.
Additionally, revenue received for the first time for sewage services provided in São Bernardo do Campo after the
acquisition of that municipality’s water and sewage assets contributed to the increase in net revenue.

Cost of Sales and Services

Cost  of  sales  and  services  for  2004  increased  by  R$186.2 million,  or  9.0%,  to  R$2,253.4 million  from
R$2,067.1 million  for  2003.    As  a  percentage  of  net  revenue  from  sales  and  services,  costs  of  sales  and  services
increased to 51.2% for 2004 from 50.0% for 2003.  The increase was primarily due to the following factors:

•

•

•

an increase of R$75.6 million, or 23.5%, in electric power costs; R$53.5 million of this increase
was due to an approximately 17.5% increase in electricity tariffs and R$22.1 million was due to
increased provisions for electricity costs incurred but not yet measured or billed by the electricity
company;

an  increase  of  R$53.2 million,  or  25.7%  in  outside  services,  primarily  due  to  the  costs  of
R$47.0 million  relating  to  the  implementation  of  our  “Global  Sourcing”  maintenance  and
materials project, works resulting from the acquisition of the São Bernardo do Campo water and
sewage  systems  in  the  amount  of  R$9.8 million,  and  maintenance  of  operational  systems  and
security services; and

an increase of R$31.0 million, or 5.7%, in depreciation and amortization expenses, principally due
to recognition of sites under construction as permanent assets.

Gross Profit

As a result of the above factors, gross profit for 2004 increased by R$80.1 million, or 3.9%, to R$2,143.7 million
from R$2,063.6 million for 2003.  As a percentage of net revenue from sales and services, gross profit decreased to
48.8% for 2004 from 50.0% for 2003.

Selling Expenses

Selling  expenses  for  2004  increased  by  R$205.0 million,  or  68.9%,  to  R$502.5 million  from  R$297.5 million  for
2003.  As a percentage of net revenue from sales and services, selling expenses increased to 11.4% for 2004 from
7.2% for 2003.

The increase in selling expenses was primarily due to the following factors:

•

an increase of R$204.0 million in bad debts expenses, net of recoveries.  This increase in bad debt
expenses was caused by a more rigorous collection of bad debts through increased legal actions.
Because accounts receivable in amounts more than R$30,000 overdue for more than 360 days old
are not generally  recognized  as bad debts  until  legal  action  is  taken,  our  decision  to  bring  more
legal  actions  and  the  deterioration  in  the  condition  of  the  municipalities  that  buy  water  on  a

60

wholesale basis significantly increased the amount of bad debts recognized in 2004.  Recoveries,
which  offset  bad  debt  expenses,  decreased  from  R$195.5 million  in  2003  to  R$62.9 million  in
2004.  A reversal of bad debt expenses in the amount of R$129.0 million, which was recorded in
2003  upon  the  acquisition  of  the  São  Bernardo  do  Campo  sewage  and  water  systems,  had  no
equivalent in 2004;

•

•

an  increase  of  R$8.1 million,  or  21.4%  in  general  expenses,  due  to  an  increase  in  fees  for  bank
collection services, and

an increase of R$7.2 million, or 5.5%, in payroll  and related  charges,  primarily  resulting from  a
4.2% increase in salaries which took effect in May 2004 and a R$1.4 million bonus paid to certain
employees in connection with financial performance.

These increases were offset by the following:

•

a decrease of R$15.6 million, or 18.9%, in outside services, primarily for debt collection services.
These services have been temporarily suspended while we re-bid the contract for these services,
and  consider  our  strategy  for  using  outside  contractors  for  collection  services.    This  decrease
should therefore not be regarded as a trend.

Administrative Expenses

Administrative expenses for 2004 increased by R$59.5 million, or 23.4%, to R$313.6 million from R$254.1 million
for 2003.   As  a percentage of  net revenue from  sales  and services,  administrative  expenses  increased  to 7.1%  for
2004 from 6.2% for 2003.  The increase in administrative expenses primarily reflected:

•

•

an  increase  of  R$27.4 million,  or  696.5%,  in  payments  to  outside  contractors,  primarily
advertising  agencies  in  connection  with  publicizing  the  water  usage  reduction  campaign,  and
professional services in connection with the issuance of debentures in September 2004; and

an  increase  of  R$25.5 million,  or  171.6%,  in  costs  for  the  implementation  of  our  geographic
information  system  SIGNOS,  which,  among  other  things,  maps  out  the  entire  municipality
infrastructure.

Financial Expenses, Net

Net  financial  expenses  consist  principally  of  interest  on  our  indebtedness,  foreign  exchange  losses  in  respect  of
indebtedness and inflation-based indexation charges relating to indebtedness, offset partially by interest income on
cash and time deposits and inflation-based indexation accruals, mainly relating to agreements entered into with some
customers to settle overdue accounts receivable.

Net financial expenses for 2004 increased by R$157.2 million, or 45.4%, to R$503.7 million from R$346.5 million
for 2003.  As a percentage of net revenue from sales and services, net financial expenses were 11.4% for 2004 and
8.4%  for  2003.    Financial  expenses  decreased  by  R$15.3  million  while  financial  income  decreased  by  R$170.4
million.

Financial expenses decreased R$15.3 million, or 2.3%.

The decrease in financial expenses was primarily due to:

•

a decrease in provisions for judicial proceedings related to interest expenses of R$99.9 million due
to  a  reduction  in  the  amounts  provisioned  with  respect  to  pending  litigation  with  suppliers  and
construction companies;

61

•

•

•

•

•

a decrease of R$74.5 million in interest and other charges relating to real-denominated debt due to
lower interest rates;

an indexation-based decrease of R$68.6 million in real-denominated debt;

a decrease in income tax on remittances  abroad in  the  amount of  R$61.1 million,  relating  to  the
recovery of amounts previously paid;

a  decrease  of  R$36.9 million  in  interest  and  other  charges  relating  to  foreign  currency-
denominated  debt  due  to  the  appreciation  of  the  real  against  the  foreign  currency  in  which  our
non-real debt is denominated; and

a  decrease  of  R$17.5 million  in  penalties  that  we  had  provided  for  with  respect  to  payment  of
COFINS  and  PASEP,  resulting  from  our  participation  in  the  “Paes”  program,  whereby  such
penalties were settled.

The  decrease  in  financial  expenses  was  partially  offset  by  a  R$360.9  decrease  in  foreign  exchange  gain  in  2004
compared to 2003, reflecting the effects on our foreign currency-denominated debt of the appreciation of the real
against the foreign currency in which our non-real debt is denominated during those periods.  In 2004, we recorded
a foreign exchange gain of R$179.7 million, resulting from an 8.8% appreciation of the real against the U.S. dollar.
In 2003, we recorded a foreign exchange gain of R$540.6 million resulting from a 22.3% appreciation of the real
against the U.S. dollar.

Financial income decreased R$170.3 million, or 54.7%, to R$141.0 million for 2004 from R$311.3 million for 2003,
primarily due to:

a  R$46.9  million  decrease  in  interest  income  from  R$70.0  million  in  2003  to  R$23.1  million  in
2004.  This decrease was primarily due to a R$130.5 million decrease in income  from  cash  and
cash equivalents as we reduced our cash balances by repaying outstanding debt; and

a decrease in income from monetary variations of R$143.6 million, primarily reflecting acquisition
of São Bernardo do Campo and the settlement of claims against the State in 2003; there were no
significant events in 2004.

As of December 31, 2004, 62.0% of our debt was real-denominated, and 77.5% of such real-denominated debt was
floating rate debt and indexed to take into account the effects of inflation.

Income (Loss) From Operations

As a result of the above factors (including, in particular, foreign exchange gains), income from operations for 2004
decreased by R$341.6 million, or 29.3%, to R$823.9 million from R$1,165.5 million for 2003.

Non-Operating Income (Expenses)

Net  non-operating  expenses  for  2004  decreased  by  R$20.6 million,  or  37.8%,  to  R$33.9 million,  from
R$54.5 million  for  2003.   In both  periods,  most  of  such  expenses  consisted  of  losses  on  disposal  of  property  and
write-offs  of  obsolete  and  other  non-productive  fixed  assets,  amounting  to  R$34.4 million  for  2004  and
R$61.7 million for 2003.

Income Tax and Social Contribution Tax

Income tax and social contribution tax (including deferred taxes) for 2004 decreased by R$0.7 million, or 0.3%, to
R$241.9 million  from  R$242.6 million  for  2003,  due  to  the  reduction  in  profit  before  income  tax  and  social
contribution  tax,  that  amounted  to  R$790.0 million  for 2004,  compared  to  a profit of  R$1,111.1 million  for  2003.

62

This reduction in profits was partially offset by the fact that we took advantage of the income tax benefit for interest
on  shareholders  equity.    This  benefit  totaled  R$52.0 million  for  2004,  compared  to  R$171.4 million  for  2003,
relating  to  interest  on  shareholders’  equity  declared  of  R$152.9  million  and  R$504.9  million  for  2004  and  2003,
respectively.

For 2004 and 2003, the statutory composite tax rate was 34.0%.

Extraordinary Item

In  accordance  with  the  requirements  of  the  CVM,  under  CVM  Deliberation  No. 371/2000,  we  have  elected  to
recognize the actuarial transition liability of R$266.1 million calculated as of December 31, 2001 with respect to our
defined  benefits  pension  plan  (Plan  G1)  on  a  straight-line  basis  against  earnings  over  the  five  years  ending
December 31, 2006.

As  permitted,  the  expense  is  presented  as  an  extraordinary  item  of  R$35.1 million  (net  of  tax  effects  of
R$18.1 million) for 2003 and 2004.

Net Income (Loss)

As a result of the above factors, net income for 2004 decreased by R$320.3 million, or 38.4%, to R$513.0 million,
compared to net income of R$833.3 million for 2003.

2003 Compared to 2002

Net Revenue from Sales and Services

Net  revenue  from  sales  and  services  for  2003  increased  by  R$363.7 million,  or  9.7%,  to  R$4,130.8 million  from
R$3,767.1 million for 2002.

Net  revenue  from  sales  and  services  relating  to  water  services  increased  by  R$197.0 million,  or  8.9%,  to
R$2,418.2 million  from  R$2,221.2 million  for  2002.    This  increase  was  primarily  due  to  an  average  increase  of
18.9% in tariffs, which came into effect on August 29, 2003, together with the continuing effect of an average tariff
increase of 8.2% in August 2002.  The volume of water distributed in 2003 decreased by 0.3%.

Net  revenue  from  sales  and  services  relating  to  sewage  services  increased  by  R$166.6 million,  or  10.8%,  to
R$1,712.5 million  from  R$1,545.9 million  for  2002.    This  increase  was  due  primarily  to  an  increase  in  tariffs,  as
sewage tariffs are set by reference to water tariffs, together with a 0.4% increase in volume.

Cost of Sales and Services

Cost  of  sales  and  services  for  2003  increased  by  R$252.2 million,  or  13.9%,  to  R$2,067.2 million  from
R$1,815.0 million  for  2002.    As  a  percentage  of  net  revenue  from  sales  and  services,  costs  of  sales  and  services
increased to 50.0% for 2003 from 48.2% in 2002.  The increase in cost of sales and services was primarily due to the
following factors:

•

an  increase  of  R$139.5 million,  or  21.4%,  in  payroll  and  related  costs  primarily  resulting  from
(1) a 14.45% increase in salaries which took effect in May 2003 and a 2.0% increase in salaries of
certain  employees  in  connection  with  the  Performance-based  Compensation  Plan  (as  from
September 2003), (2) a R$2.4 million increase in profit-sharing from R$26.9 million for 2002 to
R$29.3 million for 2003, (3) the recognition in 2003 of pension and retirements benefits granted or
to  be  granted  to  our  employees  totaling  R$17.3 million,  (4)  allocation  of  R$12.8 million  for
former  employees  who  left  the  company  through  the  PDI—Dismissal  Encouragement  Program
and R$13.2 million of related charges;

63

•

•

•

an  increase  of  R$56.3 million,  or  21.3%,  in  energy  costs  mainly  due  to  an  increase  in  electric
power tariffs and consumption volumes;

an increase of R$42.8 million, or 8.5%, in depreciation expenses principally due to recognition to
sites under construction as permanent assets; and

an increase of R$10.9 million, or 14.0%, in the costs of materials used in the treatment of water
and sewage.  The increase in cost was largely a result of the recent drought, which led to lower
quality in water in 2003 as compared to 2002 and so increased our need for these materials.  The
increase was also due to an increase in prices of these materials.

Gross Profit

As a result of the above factors, gross profit for 2003 increased by R$111.5 million, or 5.7%, to R$2,063.6 million
from R$1,952.2 million for 2002.  As a percentage of net revenue from sales and services, gross profit decreased to
50.0% for 2003 from 51.8% for 2002.

Selling Expenses

Selling  expenses  for  2003  decreased  by  R$87.6 million,  or  22.7%,  to  R$297.5 million  from  R$385.1 million  for
2002.  As a percentage of net revenue from sales and services, selling expenses decreased to 7.2% for 2003 from
10.2% for 2002.

The decrease in selling expenses was primarily due to the following factors:

•

•

a decrease of R$125.3 million, or 76.9%, in bad debt expense, net of recoveries in 2003, which is
recorded  under  selling  expenses,  mainly  due  to  recovery  against  allowances  related  to  invoices
issued to the Municipality of São Bernardo do Campo.  The municipality owed us receivables in
the  amount  of  R$265.4 million  when  subjected  to  monetary  adjustment,  and  this  amount  was
recorded as a recovery against allowances; and

a  decrease  of  R$6.9 million,  or  7.7%,  in  the  costs  of  third-party  services,  mainly  for  technical
maintenance services.

These  decreases  were  offset  by  an  increase  of  R$30.2 million,  or  30.0%,  in  payroll  and  related  charges  primarily
resulting from  (1)  a  14.5%  increase  in  salaries  which  took  effect  in  May  2003  and  a  2.0%  increase  in  salaries  of
certain employees, in connection with the Performance-based Compensation Plan (as from September 2003), (2) a
R$1.8 million increase in profit-sharing from R$4.0 million for 2002 to R$5.8 million for 2003, (3) the recognition
in  2003  of pension  and  retirements  benefits granted or  to be  granted  to our  employees  totaling  R$2.7 million,  (4)
allocation  of  R$1.8 million  for  former  employees  who  left  the  company  through  the  PDI—Dismissal
Encouragement Program and R$1.8 million of charges with respect to the Service Time Guaranteed Fund (Fundo de
Garantia  por  Tempo  de  Serviço—FGTS);  and  an  increase  of  R$10.4 million  due  to  the  readjustment  of  banking
collection services.

Administrative Expenses

Administrative expenses for 2003 increased by R$28.1 million, or 12.4%, to R$254.1 million from R$226.0 million
for 2002.   As  a percentage of  net revenue from  sales  and services,  administrative  expenses  increased  to 6.2%  for
2003 from 6.0% for 2002.  The increase in administrative expenses primarily reflected:

•

an increase of R$26.0 million in general expense costs.  The increase in general expense costs was
primarily  attributable  to  provisions  for  losses  related  to  receivables  from  suppliers  and  from
judicial deposits;

64

•

•

an  increase  of  R$17.1 million,  or  18.3%,  in  payroll  and  related  costs  primarily  resulting  from
(1) a 14.5% increase in salaries which took effect in May 2003, (2) a 2.0% increase in salaries of
certain  employees,  in  connection  with  the  Performance-based  Compensation  Plan  (as  from
September 2003), and (3) a R$1.0 million increase in profit-sharing from R$3.8 million for 2002
to R$4.8 million for 2003, a recognition  of  R$2.9 million relating  to  the  liability  of  pension  and
retirements benefits granted or to be granted to our employees after retirement, and allocation of
R$2.8 million  for  former  employees  who  left  the  company  through  the  PDI—Dismissal
Encouragement Program and R$2.4 million of related charges; and

an increase of R$2.6 million in depreciation expenses principally due to recognition of sites under
construction as permanent assets.

These increases were offset by:

•

a  decrease  of  R$20.4 million  in  the  costs  of  third-party  services  mainly  due  to  the  reduction  in
services for publicity and lease of information technology equipment.

Financial Expenses, Net

Net  financial  expenses  consist  principally  of  interest  on  our  indebtedness,  foreign  exchange  losses  in  respect  of
indebtedness and inflation-based indexation charges relating to indebtedness, offset partially by interest income on
cash and time deposits and inflation-based indexation accruals mainly relating to agreements entered into with some
customers to settle overdue accounts receivable.

Net  financial  expenses  for  2003  decreased  by  R$1,929.8 million,  or  84.8%, 
to  R$346.5 million  from
R$2,276.3 million  for  2002.    As  a  percentage  of  net  revenue  from  sales  and  services,  net  financial  expenses
decreased to 8.4% for 2003 from 60.4% for 2002.

The absolute and relative decreases in net financial expenses were primarily due to a foreign exchange gain in 2003
as compared to 2002, reflecting the effects on our foreign currency-denominated debt of the significant recovery of
the real against the foreign currency in which our non-real debt was denominated in 2003.  Foreign exchange gain
was R$540.6 million for 2003 as compared to the foreign exchange loss of R$1,345.3 million in 2002.

Interest and other charges on real-and foreign-currency loans and financings for 2003 increased by R$46.1 million,
or 6.2%, to R$785.0 million from R$738.9 million for 2002.  This increase was principally due to:

•

•

an increase of R$62.0 million in interest relating to, and other charges related to indexation-based
increases in the principal amount of, our real-denominated debt in 2003; and

decrease of R$20.9 million of interest and other charges related to a decrease in foreign-currency
denominated  indebtedness  when  translated  into  reais  as  a  result  of  the  appreciation  of  the  real
against the foreign currency in which our non-real debt was denominated in 2003.

As of December 31, 2003, all of our real-denominated debt was floating rate debt and indexed to take into account
the effects of inflation.

Interest  income  for  2003  increased  by  R$1.0 million,  or  1.4%,  to  R$70.0 million  from  R$69.0 million  for  2002.
This increase was primarily due to increase in interest earned from cash and time deposits.

In  addition,  indexation  accruals  relating  to  overdue  accounts  receivable  increased  by  R$163.2 million  to
R$241.4 million  for  2003  as  compared  to  R$78.2 million  for  2002.    This  increase  was  principally  due  to
(1) a renegotiation of existing agreements with some customers to pay overdue accounts receivable over time based
on inflation-based indexation arrangements, (2) recognition of R$75.0 million resulting from the monetary variation
on accounts receivable from the Municipality of São Bernardo do Campo, recorded in connection with the purchase

65

agreement  and  (3)  the  recognition  of  R$58.5 million  resulting  from  monetary  variation  recorded  on  amounts  due
from the State in connection with the settlement agreement reached with the State.

Income (Loss) from Operations

As a result of the above factors (including, in particular, foreign exchange gains) income from operations for 2003
totaled R$1,165.5 million as compared to the loss from operations of R$935.3 million for 2002.

Non-Operating Income (Expenses)

Net  non-operating  expenses  for  2003  increased  by  R$51.0 million,  or  1,490.4%,  to  R$54.5 million  in  2003  from
R$3.4 million  for  2002.    The  non-operating  expenses  were  primarily  due  to  R$61.7 million  in  dispositions  and
write-offs of obsolete and other non-productive fixed assets in 2003 as compared to R$16.5 million in dispositions
and write-offs in 2002.

The decrease in non-operating income of R$8.5 million, or 49.4%, to R$8.7 million in 2003, from R$17.2 million in
non-operating  income  in  2002,  was  primarily  due  to  decreases  in  donations  of  property,  plant  and  equipment
received in 2003 and to decreases income from the provision of technical assistance to municipalities where we do
not provide water and sewage services.

Income Tax and Social Contribution Tax

Income  tax  and  social  contribution  tax  for  2003  increased  by  R$566.0 million,  or  175.0%,  to  an  expense  of
R$242.6 million from benefit of R$323.3 million for 2002.

Although for 2003 we had pre-tax income, we had an income tax benefit which was directly related to the interest on
shareholders’ equity paid or accrued within that year which was not charged to pre-tax income as it is treated in a
manner  similar  to  a  dividend  but  generates  a  tax  deductible  expense.    That  benefit  amounted  to  R$171.4 million,
representing approximately 15.4% of the R$1,111.1 million pre-tax income in 2003.

Although for 2002 we had pre-tax loss, we had an income tax benefit which was directly related to the interest on
shareholders’ equity paid and or accrued within that year which was not charged to pre-tax income as it is treated in
a manner similar to a dividend but generates a tax deductible expense.

For both 2003 and 2002, the statutory composite tax rate was 34.0%.

Extraordinary Item

In  accordance  with  the  requirements  of  the  CVM,  under  CVM  Deliberation  No. 371/2000,  we  have  elected  to
recognize the actuarial liability calculated as of December 31, 2001 with respect to our defined benefits pension plan
(Plan G1) on a straight-line basis against earnings over the five years ending December 31, 2006.

As  permitted,  the  expense  is  presented  as  an  extraordinary  item  of  R$35.1 million  (net  of  tax  effects  of
R$18.1 million) for 2003.

Net Income (Loss)

As  a  result  of  the  above  factors,  we  had  net  income  for  2003  of  R$833.3 million,  compared  to  a  net  loss  of
R$650.5 million for 2002.

Liquidity and Capital Resources

Capital Sources

In  order  to  satisfy our  liquidity  and capital  requirements, we  have primarily  relied  on  cash  provided  by  operating
activities,  borrowings  from  Brazilian  Federal  and  State  governmental  financial  institutions,  and  financing  from
multilateral organizations and from domestic and international capital markets.  As of December 31, 2004, we had
R$105.6 million of cash and cash equivalents.  Outstanding short-term debt was approximately R$1,496.8 million as
of  December  31,  2004,  of  which  R$950.1 million  was  denominated  in  foreign  currency.    Long-term  debt  was
approximately  R$5,553.8 million,  of  which  R$1,730.8 million  consisted  of  foreign  currency-denominated
obligations.    We  believe  that  we  have  sufficient  sources  of  liquidity  and  capital  to  meet  our  liquidity  and  capital
requirements for the next few years, in light of our current  financial position  and our  expected  cash generated by
operating activities.

Cash  Provided  by  Operating  Activities.    Cash  provided  by  operating  activities  is,  and  we  anticipate  that  it  will
continue to be, the single largest source of our liquidity and capital resources in future years and financial periods.
Our  cash  generated  by  operating  activities  was  R$1,764.8 million  in  2002,  R$1,655.3 million  in  2003  and
R$1,436.1 million in 2004.

We have overdue accounts receivable from the State and from the municipalities to which we provide water on a
wholesale basis.  For more information please see “Item 7.  Major Shareholders and Related Party Transactions—
Related Party Transactions.”

Debt Financing.  As of December 31, 2004, we had approximately R$5,553.8 million in long-term debt outstanding
(excluding  the  current  portion  of  long-term  debt),  of  which  approximately  R$1,730.8 million  consisted  of  foreign
currency-denominated long-term debt.  We had outstanding short-term debt of approximately R$1,496.8 million as
of December 31, 2004, representing the current portion of our long-term debt.

As  of  December  31,  2004,  approximately  R$950.1 million  of  this  short-term  debt  was  denominated  in  foreign
currencies.    Substantially  all  of  our  foreign  currency-denominated  debt  of  R$2,681.0 million  as  of  December  31,
2004 was denominated in U.S. dollars or in baskets of foreign currencies.

It consisted principally of:

•

•

•

•

U.S.$457.8 million (R$1,215.2 million) in loans from the Inter-American Development Bank;

U.S.$11.8 million (R$31.2 million) in loans from the World Bank;

U.S.$500.0 million  (R$1,327.2 million)  in  aggregate principal  amount of  10.0%  Notes  due  2005
and of 12.0% Notes due 2008 sold in the international capital markets in  July  1997 and  in  June
2003, respectively; and

an aggregate of U.S.$20.0 million (R$53.1 million) in syndicated loans.

Our borrowings from multilateral institutions, such as the World Bank and the Inter-American Development Bank,
have in the past been, and in the future are likely to be, guaranteed by the Government of the State or the Federal
Government.  We do not pay fees for these guarantees.

Our  outstanding  domestic  debt  was  approximately  R$4,369.8 million  as  of  December  31,  2004  and  consisted
primarily of real-denominated loans from Federal and State-owned banks (in particular, Banco do Brasil S.A. and
Caixa Econômica Federal) and debentures issued in April 2001, April 2002 and September 2004.

In addition, we entered into a credit agreement on August 6, 2004 with the Japan Bank for International Cooperation
(“JBIC”) for the financing of the Environmental Recovery Program for the Santos Metropolitan Region, which was

67

guaranteed by the Federal Government for an aggregate principal amount of R$588.0 million.  No disbursement has
been made yet on this loan.  In addition to the amount received under the JBIC credit agreement, we intend to invest
up to R$493.0 million in this program.  In addition, we are currently negotiating with BNDES and Caixa Econômica
Federal for additional loans to finance portions of our capital expenditure program.

On September 17, 2004, we filed with the CVM a securities shelf program through which we will be able to offer
certain  debt  securities,  including  non-convertible  debentures  and  commercial  paper  up  to  an  aggregate  amount  of
R$1.5 billion over the next two years from September 17, 2004.  As part of this program, we issued R$600.0 million
in  aggregate principal  amount  of  debentures  in  September  2004  (our  sixth  issue),  offered  in  three  separate  series.
The  debentures  of  the  first,  second  and  third  series  will  mature  within  three,  five  and  six  years  after  issuance,
respectively.  The debentures of the first series in the amount of R$231.8 million will pay interest at the CDI rate
plus  1.75%  per  year,  and  the  debentures  of  the  second  in  the  amount  of  R$188.3 million  and  third  series  in  the
amount  of  R$179.9 million  will  pay  interest  at  rates  of  IGP-M  plus  11.0%  per  year.    Under  this  securities  shelf
program we also issued R$300.0 million in aggregate principal amount of debentures in March 2005 (our seventh
issue), offered in two series.  The debentures of the first and second series will mature within four and five years,
respectively,  after  issuance.    The  debentures  of  the  first  series,  in  the  total  amount  of  R$200.0 million,  will  pay
interest  at  the  CDI  rate  plus  1.5%  per  year,  and  the  debentures  of  the  second  series,  in  the  total  amount  of
R$100.0 million, will pay interest at the rate of IGP-M plus 10.8% per year.  We also issued, under this securities
shelf program, R$600.0 million in aggregate principal amount of debentures in June 2005 (our eighth issue), offered
in two series.  The debentures of the first and second series will mature within four and six years, respectively, after
issuance.  The debentures of the first series, in the total amount of R$300.0 million, will pay interest at the DI rate
plus 1.5% per year, and the debentures of the second series, in the total amount of R$300.0 million, will pay interest
at the rate of IGP-M plus 10.75% per year.

All  of  our  real-denominated  debt  is  indexed  to  take  into  account  the  effects  of  inflation.    Most  of  our  real-
denominated  debt  provides  for  inflation-based  increases  in  their  respective  principal  amounts;  the  increases  are
determined by reference to the daily government interest rate (Taxa Referencial—TR) plus an agreed margin.

We are subject to covenants under agreements evidencing or governing our outstanding indebtedness, including but
not limited to those set forth in a loan agreement with the Inter-American Development Bank, the indenture relating
to the 10.0% Notes due 2005, the indenture relating to the 12.0% Notes due 2008 and the loan agreements relating to
the syndicated loans.  Each of these agreements contains, among other provisions, limitations on our ability to incur
debt.  The indenture relating to the 10.0% Notes due 2005 and the indenture relating to the 12.0% Notes due 2008
are the most stringent of these debt agreements.  Both of these indentures prohibit, subject to some exceptions, the
incurrence of additional debt in the event that (1) the ratio of  Indebtedness  to Adjusted  Capitalization (as defined
therein) is greater than 0.42x or (2) the Debt Service Coverage Ratio (as defined in the indentures) is less than 2.50x.
These  ratios  are  calculated  using  financial  statements  prepared  under  the  constant  currency  method  (which  is  an
accounting  methodology  that  differs  from  the  Brazilian  Corporate  Law  Method  and  that  incorporates  inflation
accounting no longer commonly used in Brazil).  We do not believe that these covenants will impose constraints on
our ability to finance our capital expenditure program or, more generally, to develop our business and enhance our
financial performance.  As of December 31, 2004, our ratio of Indebtedness to Adjusted Capitalization was 0.26x

69

and our Debt Service Coverage Ratio was 2.79x, in each case as calculated in accordance with the above-mentioned
indentures.

Brazilian regulations provide that a state-owned company, such as ours, must, subject to some exceptions, use the
proceeds  of  “external  credit  operations”  (i.e.,  foreign  currency  borrowings)  to  refinance  outstanding  financial
obligations.    Until  so  used,  these  proceeds  must  be  deposited  as  directed  by  the  Central  Bank.    The  deposit
requirement  does  not  apply  in  the  case  of  import  financing  and  financing  transactions  involving  multilateral  and
official organizations, such as the Japan Bank for International Cooperation, the World Bank and the Inter-American
Development Bank.

Capital Requirements

We  have,  and  expect  to  continue  to  have,  substantial  liquidity  and  capital  resource  requirements.    These
requirements include debt-service obligations, capital expenditures to maintain, improve and expand our water and
sewage systems, payment of pension plan and other employee benefits, including pension plan payments to certain
of our former employees on behalf of the State, and dividend payments and other distributions to our shareholders,
including the State.

Debt-Service Obligations.  Our debt service obligations as of December 31, 2004 were as follows:

(in millions of reais)

2009 and

We believe that we can service this maturity schedule through a combination of funds generated by operations, the
net  proceeds  of  new  issuances  of  debt  securities  in  the  Brazilian  and  international  capital  markets  and  additional
borrowings from domestic and foreign lenders.  Our borrowings  are not  affected by  seasonality.   For  information
concerning the current interest rates borne by our outstanding indebtedness, see note 9 to our financial statements.

Capital  Expenditures.    Our  cash  disbursements  for  purchases  of  property,  plant  and  equipment  under  our  capital
expenditure program totaled approximately R$670.3 million in 2004 and R$641.3 million in 2003, as compared with
R$586.0 million in 2002.  Our capital expenditure program will require total expenditures of approximately R$4.2
billion  in  the  period  from  2005  through  2009,  including  approximately  R$758.1  million  in  2005  and  R$880.0
million in 2006.

Pension  Plan  Payments  and  Employee  Benefits.    We  have  been  making  State-mandated  special  retirement  and
pension payments to certain former employees who were employed by our predecessor entities prior to May 1974.
These special payments totaled R$85.3 million in 2004, R$87.1 million in 2003 and R$77.6 million in 2002.  The
State  is  required  to  reimburse  us  for  such  amounts,  but  has  not  been  paying  us  on  a  timely  basis.    The  State’s
obligation to us for these amounts is recorded under receivable from shareholder on the balance sheet and totaled
R$576.3 million as of December 31, 2004.  As of December 31, 2002 these receivables totaled R$403.9 million and
were classified as current and non-current assets.  As of December 31, 2003 they reached R$491.0 million and were
reclassified to non-current assets in our financial statements.  The special payments to former employees made by us
are not reflected in our statement of operations, but nonetheless represent a significant component of our liquidity
requirements.    Although  we  have  had  discussions  with  the  State  regarding  more  timely  reimbursement  for  the
special payments to former employees, we cannot assure you as to when or whether such payments will be made by
the State.  We may continue to be held responsible for these special payments to former employees, irrespective of
whether the State reimburses us or not.

The December 2001 agreement discussed above provided that the legal advisors of the State Finance Secretariat of
São Paulo would carry out specific analyses, which have commenced, to ensure agreement among the parties as to
the  methodology  employed  in  determining  the  amount  of  reimbursement  for  pension  benefits  owed  to  us  by  the
State.    The  commencement  of  payments  with  respect  to  pension  amounts  owed  to  us  by  the  State  has  been
postponed until these analyses are completed, the appraisal report is approved and the credit assignments relating to

70

the transfer of the reservoirs described above are formalized.  Under the December 2001 agreement, the original first
payment was to be made in July 2002.

Tax  Financing  Agreements.    We  did  not  make  payments  in  respect  of  certain  Brazilian  federal  income  tax  and
social contribution liabilities during the period from 1991 to mid-1996 mainly because we were contesting certain
assessments  by  the  federal  tax  authorities  and,  in  the  case  of  1993  and  1994,  because  we  did  not  have  sufficient
funds  to  meet  all  of  our  then  existing  liquidity  and  capital  resources  requirements.    Under  the  Programa  de
Recuperacão Fiscal—REFIS tax recovery program, we entered into an agreement with the Brazilian tax authorities
regarding these tax obligations and have agreed to make payments on them in monthly installments ending in 2005.
We are also required to pay interest on the unpaid balance of this tax liability.  However, in July 2003, we included
the amounts due under the REFIS program in another program called PAES, which is an alternative payment plan
for  taxes  owed.    In  accordance  with  this  settlement  agreement,  we  are  paying  amounts  due,  of  approximately
R$317.0 million, in 120 monthly installments, from July 2003.  See note 11 to our financial statements.  Payments in
respect of this aggregate tax liability continue to constitute a liquidity and capital resource requirement that must be
satisfied.

Dividend  Distributions.    We  are  required  by  our  by-laws  to  make  dividend  distributions,  which  can  be  made  as
payments  of  interest  on  shareholders’  equity  to  our  shareholders  in  an  amount  equal  to  not  less  than  25%  of  the
amounts available for distribution.  The aggregate amount of distributions we made for 2002, 2003 and 2004 were
R$108.2 million, R$504.1 million and R$152.9 million, respectively.

On  February  26,  2004,  our  Board  of  Directors  approved  the  payment  of  dividends,  in  the  form  of  interest  on
shareholders’  equity,  in  the  amount  of  R$39.3 million,  to  be  paid  within  60  days  after  our  2005  shareholders’
meeting to shareholders of record as of March 15, 2004.  On December 16, 2004, our Board of Directors approved
the  payment  of  dividends,  in  the  form  of  interest  on  shareholders’  equity,  in  the  amount  of  R$85.4 million,  to  be
paid within 60 days after our 2005 shareholders’ meeting to shareholders of record as of December 29, 2004.  On
January  13,  2005,  our  Board  of  Directors  approved  the  payment  of  dividends,  in  the  form  of  interest  on
shareholders’  equity,  in  the  amount  of  R$  28.2 million,  to  be  paid  within  60  days  after  our  2005  shareholders’
meeting to shareholders of record as of February 10, 2005.  We currently are unable to determine the amount, if any,
of its portion of these declared dividends that the State will apply to current and future accounts receivable owed to
us by the State or its controlled entities.

Interest on Shareholders’ Equity

Brazilian corporations are permitted to distribute dividends in the form of a tax-deductible notional interest expense
on  shareholders’  equity  in  accordance  with  Law  No. 9,  249,  dated  December  26,  1995,  as  amended.    The  rate  at
which tax-deductible interest may be paid is limited to the product of the average Taxa de Juros de Longo Prazo-
TJLP (a long-term interest rate published by the Brazilian government) and shareholders’ equity during the relevant
period and cannot exceed the greater of:

•

•

50% of net  income  (before  taking  into  account  such distribution  and  any  deductions  for  income
taxes and after taking into account any deductions for social contributions on net profits) for the
period in respect of which the payment is made; and

50% of retained earnings.

Distribution  of  interest  on  our  shareholders’  equity  is  a  tax-deductible  expense,  for  both  income  tax  and  social
contribution purposes.  The amount paid to shareholders as interest on shareholders’ equity, net of any withholding
tax, may be included as part of any mandatory dividend.  We are required to pay a mandatory dividend of not less
than 25% of our net income, subject to some exceptions and adjustments.

For tax purposes, payments of interest in shareholders’ equity are recognized when the payments are declared, not
when they are paid, within 60 days of the following annual shareholders’ meeting.  In 2002, we declared that we
would pay our shareholders interest on shareholders’ equity to be paid after our 2003 annual shareholders’ meeting.
In April, May and November 2003 and January 2004, we declared interest on shareholders’ equity to be paid after

71

our 2004 annual shareholders’ meeting.  In February and December 2004 and January 2005, we declared interest on
shareholders’ equity to be paid after our 2005 annual shareholders’ meeting.

Interest on shareholders’ equity is recorded as part of, but is immediately reversed under, the financial expenses line
item in our statement of operations.  The tax deduction relating to distributions of interest on shareholders’ equity is
reflected  under  the  income  tax  and  social  contribution  line items  in  our  statement  of operations.    This  tax  benefit
consequently contributes positively to net income (loss) in our statement of operations.

U.S. GAAP Reconciliation

Our  net  income  (loss)  in  accordance  with  the  Brazilian  Corporate  Law  Method  was  R$(650.5)  million  in  2002,
R$833.3 million  in  2003,  and  R$513.0 million  in  2004.    Under  U.S. GAAP,  we  would  have  reported  net  income
(loss) of R$(847.6) million in 2002, R$642.6 million in 2003, and R$417.5 million in 2004.

Our  shareholders’  equity  in  accordance  with  the  Brazilian  Corporate  Law  Method  totaled  R$7,246.5 million  at
December 31, 2002, R$7,576.9 million at December 31, 2003 and R$7,951.6 million at December 31, 2004.  Under
U.S. GAAP,  we  would  have  reported  shareholders’  equity  of  R$5,945.8 million  at  December  31,  2002,
R$6,085.6 million at December 31, 2003 and R$6,364.8 million at December 31, 2004.

The principal differences between the Brazilian Corporate Law Method and U.S. GAAP that affect our net income
(loss) in 2002, 2003 and 2004, as well as shareholders’ equity at December 31, 2002, 2003 and 2004, relate to the
treatment of the following items:

•

•

•

•

•

additional  inflation  restatements  and  related  depreciation  which  would  be  mandated  by  U.S. GAAP  (but
which are not permitted under the Brazilian Corporate Law Method) for 1996 and 1997 in recognition of
Brazil’s status as a highly inflationary country in those years;

revaluations  of  property,  plant  and  equipment  recorded  in  1990  and  1991  under  the  Brazilian  Corporate
Law Method, which would be reversed and partially replaced by supplemental inflation restatements based
upon a general price index (IGP-M) for periods prior to 1990 under U.S. GAAP;

pension  plan  (Plan  G0)  payments  and  other  employee  benefits  for  former  employees  of  our  predecessor
companies which are obligations of the State and which are not treated as our expenses under the Brazilian
Corporate  Law  Method,  but  which  would  be  required  to  be  treated  as  our  expense  on  an  actuarial  basis
under U.S. GAAP;

pension plan (Plan G1) expenses which, through December 31, 2001, were recognized on an accrual basis
only  to  the  extent  of  required  contributions  for  the  relevant  year  or  financial  period  under  the  Brazilian
Corporate  Law  Method,  but  which  would  be  required  to  be  fully  recorded  on  an  actuarial  basis  under
U.S. GAAP.  Since January 1, 2002 under the Brazilian Corporate Law Method, recognition on an actuarial
basis  is  required.    There  are  some  differences  as  compared  with  U.S. GAAP,  basically  regarding  the
calculation  method,  amortization  period  and  recognition  rules,  resulting  in  different  pension  cost
obligation; and

additional  accounting  items,  including,  among  others,  capitalized  interest,  expensing  of  deferred  charges
and deferred taxes and the voluntary redundancy plan.

See  note  23  to  our  audited  financial  statements  for  a  description  of  these  differences  as  they  relate  to  us  and  a
reconciliation  of  net  income  (loss)  and  total  shareholders’  equity  from  the  Brazilian  Corporate  Law  Method  to
U.S. GAAP.

DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Management

Under our by-laws and the Brazilian Corporate Law, we are managed by our Board of Directors, which currently
consists  of  eight  directors,  and  a  Diretoria,  or  Executive  Committee,  which  currently  consists  of  six  executive
officers.

As our majority shareholder, the State has the ability to control the election of the Board of Directors and, therefore,
our  direction  and  future  operations.    Upon  the  election  of  a  new  Governor  and  any  resulting  change  in  the
administration  of  the  State,  all  or  some  of  the  members  of  the  Board  of  Directors,  including  the  Chairman,  have
historically been replaced by designees of the new administration.  The Board of Directors may in turn replace some
or all of the executive officers.

Board of Directors

Our  by-laws  provide  for  a  minimum  of  five  and  a  maximum  of  10  directors.    The  members  of  our  Board  of
Directors are elected at a general meeting of shareholders to serve renewable one-year terms.  Each member of our
Board of Directors must be one of our shareholders, under the Brazilian Corporate Law, and a resident of Brazil,
under our by-laws.  Pursuant to our by-laws, our employees have the option to elect one member of our Board of
Directors, who must be an employee with more than two years of service to us.  Currently, our employees have not
elected  a  director.    In  addition,  pursuant  to  the  Brazilian  Corporate  Law,  at  least  one  member  of  the  Board  of
Directors of mixed capital companies, such as us, must be appointed by the minority shareholders.

The current members of our Board of Directors were elected in the annual shareholders’ meeting held on April 29,
2005.    The  tenure  of  the  directors  will  end  upon  the  election  of  the  new  members  at  the  annual  shareholders’
meeting to be held on April, 2006.

Our Board of Directors ordinarily meets once a month or when called by a majority of the directors or the Chairman.
Its responsibilities include the establishment of policy and general orientation of our business and the appointment
and supervision of our executive officers.

Conselho Fiscal

Our Conselho Fiscal, or fiscal council, which is established on a permanent basis and generally meets once a month,
consists  of  five  members  and  five  alternates  elected  at  the  annual  shareholders  meeting  for  renewable  one-year
terms.    The  primary  responsibility  of  the  Conselho  Fiscal,  which  is  independent  from  management  and  from  the
external auditors appointed by our Board of Directors, is to review our financial statements and report on them to
our shareholders.  The fiscal council may, under certain conditions, call an annual shareholders’ meeting or a special
shareholders’ meeting.

76

The  current  members  and  alternate  members  of  our  Conselho  Fiscal  were  elected  in  the  annual  shareholders’
meeting held on April 29, 2005.  The tenure of the members and alternate members of our Conselho Fiscal will end
upon the election of the new members and alternate members at the annual shareholders’ meeting to be held in April
2006.

The following are the current members and alternate members of our Conselho Fiscal:

Corporate Governance Practices

The  significant  differences  between  our  corporate  governance  practices  and  the  New  York  Stock  Exchange
standards  can  be  found  on  our  website,  www.sabesp.com.br.    The  information  found  at  this  website  is  not
incorporated by reference into this document.

Compensation

Pursuant to the Brazilian Corporate Law, our shareholders are responsible for establishing the aggregate amount of
compensation we pay to the members of our Board of Directors, members of our fiscal council and our executive
officers.    Our  Board  of  Directors  will  determine  the  individual  levels  of  compensation  paid  to  each  director,
executive officer and fiscal council member based on this aggregate amount.

For the year ended December 31, 2004, the aggregate compensation, including benefits in kind granted, that we paid
to members of our Board of Directors and to our executive officers for services in all capacities was approximately
R$1.8 million.  In addition, in 2004, the executive officers accrued pension benefits of approximately R$0.3 million,
and we have set aside R$0.3 million with respect to such pension benefits.  The members of our Board of Directors
did not receive any such benefits.

None  of  our  directors  and  executive  officers  is  party  to  an  employment  contract  providing  for  benefits  upon
termination of employment, except for those officers who are also our employees, in which case they are granted all
benefits regularly applicable.  We do not have stock-option plans for our directors and executive officers.

Employees

At December 31, 2004, we had 17,735 full-time employees.  During 2004, we had an average of 845 trainees.

The following table sets forth the number of our full-time employees by main category of activity and geographic

The  average  tenure  of  our  employees  is  approximately  14  years.    We  also  outsource  certain  services  such  as
maintenance, delivery of water and sewage bills, meter reading, catering and security.  We believe that our relations
with our employees are generally satisfactory.

Substantially all of our non-managerial employees are members of unions.  The three main unions that represent our
employees  are  the  Sindicato  dos  Trabalhadores  em  Água,  Esgoto  e  Meio  Ambiente  de  São  Paulo—SINTAEMA,
Sindicato  dos  Trabalhadores  da  Região  Urbana  de  Santos,  São  Vicente,  Baixada  Santista,  Litoral  Sul  e  Vale
Ribeira—SINTIUS, and the Sindicato dos Engenheiros do Estado de São Paulo—SEESP.  Every year we negotiate
collective bargaining agreements, which establish the level of compensation and other benefits of our employees.

Our most recent collective bargaining agreements, which became effective on May 1, 2005 and will expire on April
30,  2006,  do  not  contemplate  total  job  protection  for  our  employees.    However,  we  have  a  formal  understanding
with the unions that represent our employees that we would not dismiss more than 2.0% of our current employees
before April 30, 2006.

We have experienced the following strikes in the last five years, none of which interrupted essential services:  a two-
day strike in December 1999, a five-day strike in January 2000, a two-day strike in June 2000, a one-day strike in
September 2001, a one-day strike in November 2001, a two-day strike in June 2002, a two-day strike in May 2003,
a  two-day  strike  in  May  2004  and  a  three-day  strike  in  June  2005.    Under  Brazilian  law,  our  non-administrative
employees are considered “essential employees” and therefore are limited in their right to strike.

Profit Sharing and Pension Plans

We  have  established  a  defined-benefit  pension  and  benefits  fund  (Fundação  Sabesp  de  Seguridade  Social,  or
SABESPREV) to provide our employees with retirement and pension benefits.  This pension plan provides defined
benefit  payments  to  former  employees  and  their  families.    Both  we  and  our  employees  make  contributions  to  the
pension plan.    Our  contributions  include  the responsibility  assumed  relating  to  service  prior  to  the  constitution  of
SABESPREV,  which  is  payable  up  to  February  2011.    We  made  contributions  to  the  pension  plan  totaling
R$11.1 million  in  2002,  R$11.6 million  in  2003  and  R$10.3 million  in  2004.    See  note 12  to  our  financial
statements.  Based on independent actuarial reports, as of December 31, 2004, our obligation under this plan was
R$328.6 million.

On  May  29,  2001,  a  Federal  law  was  enacted  which,  among  other  things,  limits  the  amount  mixed  capital
companies, like us, may contribute to their pension plans.  Specifically, the ordinary contributions we make to our
pension plans may not exceed the contributions made by the beneficiaries of these plans.

In  August  1996,  we  established  a  profit-sharing  plan  for  all  employees  who  have  been  employed  for  at  least  six
months.    In  1999,  we  did  not  pay  any  profit-sharing  amounts  to  our  employees  due  to  State  Decree  No. 43,794,
which  prohibited  any  profit-sharing  amounts  to  be  paid  in  1999  to  employees  of  state-controlled  companies,
including us.  On April 14, 2000, the State issued Decree No. 44,836 which allows for the payment of profit-sharing
amounts  on  an  exceptional  basis  provided  that  specific  authorizations  are  obtained  by  us  from  the  Wages  Policy
Commission  (Comissão  de  Política  Salarial).    We  have  obtained  such  authorization  every  year  since  2000  and
therefore paid profit-sharing amounts to our employees during this period.  On October 2, 2000, we entered into a
collective  bargaining  agreement  with  the  unions  that  represent  our  employees,  which  established  a  new  profit-
sharing plan for all employees who have been employed for at least three months.  Under the profit-sharing plan,
we,  after  negotiations  with  the  employee  labor  unions,  set  annual  company-wide  and  business  unit-specific
operational  and  financial  targets.    Payments  can  be  in  an  aggregate  amount  of  up  to  the  equivalent  of  our  total
payroll  for one  month  and  are  made  to  the  extent  of  achievement  of  such  targets.    In  the  past,  one-quarter  of  the
profit-sharing  payments  was  made  to  the  extent  that  company-wide  targets  were  satisfied,  while  the  other  three-
quarters were made to the extent the business unit-specific targets were reached.  The profit-sharing payments were
reduced,  on  a  pro  rata  basis,  if  the  targets  were  not  fully  satisfied  and  payments  were  made  semi-annually.    We
recorded  profit-sharing  expenses  of  R$34.7 million  in  respect  of  2002,  R$40.0 million  in  respect  of  2003  and

78

R$40.3 million in respect of 2004.  We believe that the profit-sharing plan has, in the past, contributed to increased
employee productivity.  We do not have a stock-option plan for our employees.

Related Party Transactions

Transactions with the State

We have entered into extensive transactions with the State, which is our controlling shareholder, and we expect to
continue to do so.  The State is our largest customer, it owns some of the facilities we use in our business, it is one of
the governmental entities that regulate our business, and it has assisted us in obtaining financing on favorable terms.

Many of our transactions with the State reflect policies of the State that depend on decisions of elected officials or
public servants and are accordingly subject to change.  They may be particularly open to reconsideration following
State elections, which are next scheduled to be held in October 2006.  Among the practices that could change are
those  described  below  concerning  the  application  of  dividends  to  offset  accounts  receivable  from  the  State,  the
provision of State guarantees, and the terms on which we use state-owned reservoir facilities.

Provision of Services

We  provide  water  and  sewage  services  to  the  Federal  Government,  the  State  and  municipal  governments  and
government  entities  in  the  ordinary  course  of  our  business.    Sales  of  water  and  sewage  services  to  the  State,
including  State  entities,  totaled  approximately  R$264.0 million  during  the  year  ended  December  31,  2004.    Our
accounts receivable from the State totaled R$245.6 million  as of December 31, 2004.   In  addition,  as required by
law, we invest our cash and cash equivalents with government financial institutions in short-term securities.

Payment of Pensions

Pursuant to a law enacted by the State, certain former employees of some State -owned companies which merged to
form our company, who provided service to us between our inception and 1974, when such law was prospectively
repealed,  acquired  a  legal  right  to receive  supplemental  pension  benefit  payments  (which  rights  are  referred  to  as
“Plan G0”).  These amounts are paid by us, on behalf of the State, and are claimed by us as reimbursements from the
State,  as primary  obligor.   During  2004,  we  made  payments  to  former  employees  of  R$85.3 million  in  respect  of

80

                             
Plan G0.  The State did not make any reimbursements in this period.  See note 6 to our financial statements.  The
amount owed to us by the State for reimbursement of these costs was R$576.3 million as of December 31, 2004.
The State, however, has not agreed with this amount.  We have undertaken to conduct a joint inquiry with the State
with respect to the methodology employed in determining such reimbursement amounts to ensure we reach a mutual
agreement.

Agreements with the State

In  September  1997,  we  and  the  State  entered  into  a  memorandum  of  understanding  providing  that  we  would,  in
effect,  apply  dividends  we  declared  that  were  otherwise  payable  to  the  State  to  offset  accounts  receivable  in
connection with the provision of water and sewage services to the State and its controlled entities.  In 1998, 2000
and  2001  we  applied  dividends,  in  the  form  of  interest  on  shareholders’  equity,  in  an  aggregate  amount  equal  to
R$1,215.6 million  due  to  the  State  in  respect  of  its  shareholding  in  us  to  settle  a  portion  of  the  unpaid  accounts
receivable from the State.  In 1999, we did not pay dividends or other distributions to our shareholders.

On December 11, 2001, we entered into an agreement with the State and the State Department of Water and Energy.
Pursuant to this agreement, the State acknowledged and agreed, subject to an audit by a State-appointed auditor, to
pay us amounts it owed us in respect of:

•

•

water  and  sewage  services  we  provided  to  governmental  agencies,  State-owned  autonomous  entities  and
foundations through December 1, 2001 in the amount of R$358.2 million; and

supplemental retirement and pension benefits we paid from March 1986 to November 2001 on behalf of the
State  to  former  employees  of  the  State-owned  companies  which  merged  to  form  our  company  in  the
amount of R$320.6 million; as we did not reach an agreement regarding such amounts, a joint inquiry has
commenced in order to ensure agreement between us and the State.

As  a  result,  R$649.1 million  of  these  amounts  became  a  long-term  receivable  from  the  State  in  our  financial
statements on December 31, 2001.

The  agreement  provided  that  the  State  Department  of  Water  and  Energy  would  transfer  to  us  ownership  of  the
Taiaçupeba, Jundiaí, Biritiba, Paraitinga and Ponte Nova reservoirs, which make up the Alto Tietê System, and that
the fair value of these assets would reduce the amounts owed to us by the State.

Under the December 2001 agreement, in July and August 2002, a State-owned construction company (Companhia
Paulista  de  Obras  e  Serviços—CPOS),  on  behalf  of  the  State,  and  an  independent  appraisal  firm  (ENGEVAL—
Engenharia  de  Avaliações),  on  our  behalf,  presented  their  valuation  reports  relating  to  the  reservoirs.    Under  the
agreement,  the  arithmetic  average  of  these  appraisals  is  deemed  the  fair  value  of  the  reservoirs.    The  appraisals
contained in these reports were in the amounts of R$335.8 million and R$341.2 million, respectively.  Because we
had already made investments in these reservoirs by then, the arithmetic average of the appraisals submitted to our
Board of Directors by August 2002, R$300.9 million, was net of a percentage corresponding to these investments.
Our Board of Directors approved the valuation reports.

Under the December 2001 agreement, for amounts due in excess of the fair value of the reservoirs, the State is to
make  payments  in  114  consecutive  monthly  installments,  with  the  first  payment  to  be  made  upon  the  latest  of
(1) 210  days  after  the  date  of  the  agreement,  (2) agreement  by  the  parties  on  the  fair  value  of  the  reservoirs  and
(3) conclusion of the audit by a State-appointed auditor of amounts owed.  The nominal amount owed by the State
would not be indexed to inflation or earn interest if there was a delay in concluding the appraisal of fair value.  The
installments  will  be  indexed  on  a  monthly  basis  by  the  IGP-M,  plus  6.0%  per  year,  starting  on  the  date  the  first
installment becomes due.

On October 29, 2003, the Public Attorney of the State (Ministério Público do Estado de São Paulo), on behalf of the
people of the State, brought a civil public action in a Trial Court of the state of São Paulo (12a Vara da Fazenda
Pública do Estado de São Paulo) alleging that a transfer to us of ownership of the Alto Tietê System reservoirs from
the  State  Department  of  Water  and  Energy  of  the  State  would  be  illegal.    An  injunction  against  the  transfer  of

81

ownership of such reservoirs was granted but was later reversed.  However, in October 2004, the court ruled in favor
of  the  Public  Attorney  of  the  State,  which  ruling  we  believe  relates  only  to  the  illegality  of  the  transfer  of  the
reservoirs.  In response, we filed an appeal which is pending final decision and the State successfully filed an action
suspending the lower Court’s decision until final judgment is reached by the Court of Appeals of the state of São
Paulo (Tribunal de Justiça do Estado de São Paulo).  We are unable to predict whether we will succeed in appealing
such  decision.    However,  we  currently  do  not  expect  that  an  eventual  unfavorable  decision  would  have  material
adverse effect on our business and financial condition.

The December 2001 agreement also provided that the legal advisors of the State would carry out specific analyses,
which have commenced, to ensure agreement among the parties as to the methodology employed in determining the
amount  of  reimbursement  for  pension  benefits  owed  to  us  by  the  State.    Our  management  does  not  expect  these
analyses to differ significantly from the amounts we have recorded in respect of these amounts.  The commencement
of payments with respect to pension amounts owed to us by the State has been postponed until these analyses are
completed,  the  appraisal  report  is  approved  and  the  credit  assignments  relating  to  the  transfer  of  the  reservoirs
described above are formalized.  In addition, the transfer of these reservoirs is currently being disputed and we are
not certain whether such transfer will be legally allowed, as discussed above.  Under the December 2001 agreement,
the original first payment was to be made in July 2002.  Based on Official Notice No. 53/2005 of the State Capital
Defense  Council  (CODEC),  dated  March  21,  2005,  negotiations  are  still  ongoing  between  the  Company  and  the
State  with  a  view  to  restatement  of  the  debt  for  supplemental  retirement  and  pension  benefits,  under  the  terms
defined in the December 2001 agreement, including amounts due after November 2001.  These negotiations will be
consolidated  in  a  second  amendment  to  the  December  2001  agreement.    The  Company  will  retain  FIPECAFI  to
validate the actual values to be reimbursed by the State, provided by the Office of the State Attorney General.  See
note 6 to our financial statements.

At  a  meeting  held  on  January  30,  2002,  our  Board  of  Directors  unanimously  declared  dividends,  in  the  form  of
interest on shareholders’ equity, in an aggregate amount of R$489.8 million.  This distribution was paid on June 25,
2002,  to  shareholders  of  record  as  of  February  7,  2002.    Accordingly,  the  State  was  entitled  to  receive
R$432.7 million  of  this  distribution  and  we  paid  the  State  R$347.3 million  of  this  amount.    The  State  applied
approximately R$202.3 million of the dividend it received to settle current accounts receivable owed by the State or
its controlled entities.  We have withheld the remaining share of the dividend that the State was entitled to pending
the State’s payment of certain accounts receivable owed to us.

At a meeting, our Board of Directors reviewed our 2002 budget, which incorporated the payment to the State, and
one of our directors voted against us making such payment.  We cannot assure you that our minority shareholders
will  not  contest  the  payment  of  a  cash  distribution  to  the  State  on  the  grounds  that  it  is  inconsistent  with  the
September 1997 protocol of understanding.

On April 29, 2002, our Board of Directors declared dividends, in the form of interest on shareholders’ equity, in an
aggregate amount of R$108.2 million, paid in June 2003 to shareholders of record as of June 17, 2002.  The State
applied the entire amount of this dividend, or R$77.4 million, to accounts receivable owed to us.

On  April  24,  May  29,  and  November  20,  2003,  and  on  January  8,  2004,  our  Board  of  Directors  approved  the
payment  of  dividends,  in  the  form  of  interest  on  shareholders’  equity,  in  aggregate  amounts  of  R$40.2 million,
R$118.2 million, R$154.9 million and R$190.8 million, respectively.  These dividends were paid on June 29, 2004.

On February 26, 2004, December 16, 2004 and January 13, 2005, our Board of Directors approved the payment of
dividends,  in  the  form  of  interest  on  shareholders’  equity,  in  the  amount  of  R$39.3 million,  R$85.4 million  and
R$28.2 million, respectively to be paid within 60 days after our 2005 annual shareholders’ meeting.

On  April  28,  2005,  our  Board  of  Directors  approved  the  payment  of  dividends,  in  the  form  of  interest  on
shareholders’ equity, in the amount of R$38.2 million, to be paid within 60 days after our 2006 annual shareholders’
meeting.

On March 22, 2004, we and the State executed the First Amendment to the December 2001 agreement.  Under this
amendment,  the  State  acknowledged  a debt  owed  to  us  of  R$581.8 million,  related  to  unpaid  accounts  receivable

82

from the State until February 29, 2004, and we acknowledged the aggregate amount of R$518.7 million due to the
State as dividends in the form of interest on shareholders’ equity.  See note 6 to our financial statements.

Accordingly, we and the State agreed to set-off each other’s credit up to the limit of R$360.7 million in seven equal
and consecutive monthly installments from June to December 2004.  The remaining amount of R$221.1 million of
the State’s consolidated debt will be paid in 60 consecutive installments of R$3.7 million which began on May 30,
2004.  These installments will be indexed according to the IPCA on a monthly basis which began in March 2004,
plus an interest rate of 0.5% per month, except for the first twelve installments, which shall be paid at the nominal
amount without any indexation or interest applied, the aggregate amount of which being R$44.2 million.

We  will  use  any  value  due  from  us  to  the  State  that  is  not  used  to  set-off  the  accounts  as  described  above  to
discharge any amounts accrued and not paid by the State in relation to its consumption of water and sewage services
after March 2004.

This amendment did not alter the payment terms and conditions related to the supplemental retirement and pension
benefits we pay on behalf of the State, which remain governed by the terms of the December 2001 agreement itself.

As  of  December  31,  2004,  the  amounts  owed  to  us  by  the  State  for  the  provision  of  water  and  sewage  services
included R$245.6 million, which was considered overdue as of February 29, 2004.  This amount does not include
R$105.5 million which the State agreed to apply in respect of dividends payable to it as part of its agreements with
us  as  discussed  above.    As  of  December  31,  2004  the  State  owed  us  an  additional  R$48.5 million  in  accounts
receivable  related  to  the  provision  of  water  and  sewage  services  rendered  from  February  2004.    With  respect  to
reimbursement for pensions paid on behalf of the State, the State owed us R$576.3 million as of December 31, 2004
(R$320.6 million  of  which  was  acknowledged  by  the  State  in  the  December  2001  agreement  with  us  subject  to  a
further audit which has not yet occurred).  We expect amounts owed to us by the State for water and sewage services
and  reimbursements  for  pensions  paid  to  increase  in  the  future.    We  have  not  established  any  provisions  for  any
amounts due to us by the State, because we expect to recover these amounts and loss is not considered probable.

Investment of Liquid Assets

Our  cash  and  cash  equivalents  invested  with  State  financial  institutions  in  short-term  securities  amounted  to
R$72.8 million as of December 31, 2004.

Government Guarantees of Financing

In  some  situations,  the  Federal  Government,  the  State  or  government  agencies  guarantee  our  performance  under
debt- and project-related agreements.

On December 17, 1992, the State entered into a loan agreement with the International Bank for Reconstruction and
Development in the amount of U.S.$119.0 million.   This  loan was guaranteed  by  the  Federal  Government  and  its
proceeds  were  designated  to  finance  the  environmental  clean-up  of  the  Guarapiranga  basin.    Pursuant  to  this
agreement, we would receive a loan from the State to be used in the expansion of the wastewater collection network
and  sewage  treatment  facilities  in  the  Guarapiranga  Reservoir.    As  a  result,  on  March 12,  1993,  we  and  the  State
entered into an agreement pursuant to which the State transferred to us U.S.$37.0 million of this loan, which loan
amount  was  increased  to  U.S.$42.5 million  pursuant  to  an  amendment  entered  into  between  the  State  and  us  in
September of 1999.  We have pledged three of our properties as collateral for this financing.  As of December 31,
2004 our outstanding debt relating to this loan was approximately U.S.$11.8 million.

The State  has  also guaranteed  a portion of our  repayment  obligations  under  loan  agreements  that  we  entered  into
with  the  Federal  Government  in  1994  and  with  Caixa  Econômica  Federal  from  1996  to  1998.    The  State  has
provided guarantees for a portion of the amount owed to the Federal Government under loan agreements signed with
Banco  do  Brasil,  which  totaled  R$2,335.0  million  as  of  December  31,  2004.    Our  obligations  under  the  loan
agreements we entered into with Caixa Econômica Federal amounted to R$498.0 million as of December 31, 2004.

83

On August 6, 2004, we entered into a credit agreement with the Japan Bank for International Cooperation for the
financing of  the  Environmental  Recovery  Program  for  the  Santos  Metropolitan  Region, which  was  guaranteed  by
the Federal Government for an aggregate principal amount of R$588.0 million.  In addition to the amount received
under  the  JBIC  credit  agreement,  we  intend  to  invest  up  to  R$493.0 million  in  this  program.    In  addition,  we  are
currently  negotiating  with  BNDES  and  Caixa  Econômica  Federal  for  additional  loans  to  finance  portions  of  our
capital expenditure program.

Use of State-Owned Reservoir Facilities

We currently use the Guarapiranga and Billings reservoirs and a portion of some of the reservoirs of the Alto Tietê
System,  which  are  owned  by  another  company  controlled  by  the  State.    We  currently  do  not  pay  any  fees  with
respect  to  the  use  of  these  reservoirs.    We  are,  however,  responsible  for  maintaining  them  and  funding  their
operating costs.  The State incurs no operating costs on our behalf.  If these facilities were not available for our use,
we would have to obtain water from more distant sources, which would be more costly.

The  arrangement  not  to  pay  any  fees  to  the  State  for  the  use  of  certain  reservoirs  of  the  Alto  Tietê  System  is
addressed by a number of formal agreements first entered into on March 31, 1992 and on April 24, 1997 and later
amended on March 16, 2000 and on November 21, 2001.  As part of these arrangements, we agreed to fund 100.0%
of  the  estimated  costs  of  the  1992  agreement  equal  to  R$27.8 million  and  75.0%  of  the  1997  agreement  equal  to
R$63.4 million  which  was  already  disbursed,  and  the  Government  of  the  State,  through  the  State  Department  of
Water  and  Energy,  agreed  to  fund  approximately  25%  of  the  estimated  costs  of  the  1997  agreement  equal  to
R$21.1 million, to construct ducts, tunnels and other facilities to interconnect the Tietê River with the Biritiba and
Jundiaí reservoirs and with other bodies of water in exchange for our use of the reservoirs over a 30-year period.
The amendments to the 1997 agreement increased our obligations under such agreement by R$5.9 million.

We have the right to draw water and release emissions into the reservoirs in the Alto Tietê system over a 30-year
period which began in 1997.

Our use of the Billings and Guarapiranga reservoirs is provided for through a grant issued by the State Department
of Water and Energy.  We have the right to use these reservoirs as long as we remain responsible for maintaining
them and funding their operating costs.

Water Use Incentive Agreements

We  have  entered  into  agreements  with  public  entities,  including  State  entities  and  municipalities,  that  manage
approximately 5,000 properties under which we provide these entities with a 25.0% tariff reduction for the water and
sewage services we provide if such entities implement our program for the rational use of water, which includes a
reduction  of  at  least  10.0%  in  water  consumption.    These  agreements  are  valid  for  a  period  of  12  months  with
automatic renewal for equal periods.  Pursuant to the terms of these agreements, if these entities fail to make any
payment  on  a  timely  basis  to  us,  we  have  the  right  to  cancel  the  agreement,  thereby  revoking  the  25.0%  tariff
reduction.

Transactions with SABESPREV Pension Fund

SABESPREV  is  the  funded  defined-benefit  pension  plan  that  we  established  to  provide  our  employees  with
retirement and pension benefits.  The assets of SABESPREV are independently held, but we nominate the majority
of directors of SABESPREV.  Both we and our employees make contributions to the pension plan.  We contributed
R$11.6 million during 2003 and R$10.3 million during 2004.

On  May  29,  2001,  a  Federal  law  was  enacted  which,  among  other  things,  limits  the  amount  mixed  capital
companies, like us, may contribute to their pension plans.  Specifically, the ordinary contributions made by us to our
pension  plans  may  not  exceed  the  contributions  made  by  the  beneficiaries  of  such  plans.    Studies  have  been
undertaken in order to cure the deficit with respect to the current plan and transform it into a defined contribution
plan.

Legal Proceedings

Labor Proceedings

In  October  1989,  the  São  Paulo  Water,  Sewage  and  Environment  Service  Workers  Union  (Sindicato  dos
Trabalhadores em Água Esgoto e Meio Ambiente de São Paulo—SINTAEMA) commenced a lawsuit, on behalf of
our employees, against us in the Labor Court (Justiça do Trabalho), alleging that we had violated Brazilian labor
laws and collective bargaining contracts when we ceased making certain payments to 21,337 of our employees in
1989.  Those payments related to previously mandated inflation-related index adjustments to such employees’ wages
and salaries, which, due to a change in applicable law, we had ceased making.  In November 1995, the Labor Court
issued a decision in favor of SINTAEMA, although it never ruled with respect to the amount of damages payable by
us.  We appealed the decision of the Labor Court and in April 1997 lost the appeal.  We appealed this decision to the
Superior Labor Court (Tribunal Superior do Trabalho) and the Superior Court ruled against us.  However, we filed a
motion  to  vacate  (ação  rescisória),  seeking  the  annulment  of  the  Superior  Court  ruling  and  obtained  a  favorable
decision.  SINTAEMA appealed this decision and a final ruling is yet to be issued by the Supreme Court.

On January 9, 1990, SINTAEMA initiated a lawsuit against us, alleging that we had failed to pay certain employee
benefits and were required to make a penalty payment to SINTAEMA under a then existing collective bargaining
agreement.  On July 31, 1992, the Labor Court issued a ruling against us, but did not award damages to SINTAEMA
at that time.  We and SINTAEMA are currently engaged in negotiations concerning the amount to be paid by us.
We  also  filed  a  writ  of  mandamus  seeking  a  court  decision  establishing  that  the  penalty  imposed  against  us  is
excessive since it exceeds the principal amount by a large margin.  Our request was denied by the courts and the
lawsuit  is now  awaiting  a final decision  at  Superior  Labor  Court  (Tribunal Superior do  Trabalho).    We  currently
cannot  predict  the  amount  that  we  will  be  required  to  pay  to  SINTAEMA,  but  we  do  not  believe  that  the  final
outcome of this matter will have a material adverse effect on our business, results of operations, financial condition
or prospects.

We are defendants in approximately 1,700 labor proceedings and in one civil public action initiated by and on behalf
of some of our current and former employees relating to certain benefits awarded by Law No. 4,819, of August 26,
1958.  Approximately 40 of these plaintiffs are also seeking the same benefits in the civil courts.  In all cases, we
claim  that  the  State,  and  not  us,  is  responsible  for  the  payments  due  to  the  plaintiffs.    Some  labor  and  civil
proceedings  have  been  ruled  upon  by  the  lower  courts,  but  no  final  decision  has  been  issued  in  any  of  the  legal
proceedings as of the date of this annual report.  An injunction was granted at the first instance in the civil public
action to compel us to pay the benefits awarded by Law No. 4,819 to all plaintiffs in that lawsuit.  As of the date of
this annual report, we and the State have not agreed on the amounts to be reimbursed.  The civil public action is now
awaiting decision on the merits.

We  are  party  to  other  lawsuits  and  administrative  proceedings  involving  SINTAEMA  and  current  and  former
employees.  We do not believe that any liabilities relating to these other lawsuits or administrative proceedings will
have a material adverse effect on our business, results of operations, financial condition or prospects.

As of December 31, 2004, we had established a provision totaling R$25.9 million with respect to potential damages
in lawsuits and administrative proceedings involving present and former employees, including the lawsuit described
in the preceding paragraphs, based on calculations made by our legal and human resources departments.

Tax Proceedings

On  May  28,  1999,  we  filed  a  lawsuit  challenging  a  law  enacted  in  1998  that  expanded  the  definition  of  revenue
subject to public service taxes (Programa de Formação de Patrimônio do Servidor Público— PASEP) and increased

85

the  social  security  contribution  tax  (Contribuição  para  Financiamento  da  Seguridade  Social—COFINS)  rate.
However,  in  July  2003,  we  withdrew  our  lawsuit  and  included  the  amounts  owing  under  this  lawsuit  and  the
amounts  due  under  the  REFIS  program  (a  tax  recovery  program),  in  another  program  called  PAES,  which  is  an
alternative  payment  plan  for  taxes  owed.    In  accordance  with  the  PAES  tax  recovery  program,  we  are  paying
amounts  subject  to  the  settlement  agreement  in  120  monthly  installments,  which  began  in  July  2003.    As  of
December 31, 2004, the amount due under the PAES program was R$308.6 million.

We initiated legal action in July 1999 to challenge the creation by the Municipality of City of São Paulo of a tax on
the use of public areas.  The tax would apply to our water and sewage mains and other installations located in public
areas.  Based on the advice of our internal legal counsel, we believe that this municipal tax is unlawful because it
was established by a municipal decree instead of a municipal statute.  We are currently disputing the creation of this
tax  and  any  related  tax  assessment.    On  May  11,  2000,  the  trial  court  of  the  state  of  São  Paulo  (12a. Vara  da
Fazenda Pública do Estado de São Paulo) issued a decision upholding this municipal tax.  We have appealed the
trial court decision to the Court of Appeals of the state of São Paulo (Tribunal de Justiça do Estado de São Paulo).
A recently approved law enacted the tax on the use of public areas in the city of São Paulo.  In April 2004, we filed a
request for injunction seeking the suspension of the tax assessment by the municipality.  The injunction was granted
on  first  instance  and  we  are  now  awaiting  decision  on  the  merits.    We  currently  cannot  estimate  the  potential
increase in our expenses if we were required to pay this tax or if any future assessment of this tax will be retroactive
to  1999.    To  date,  we  have  not  established  a  provision  for  any  potential  expense  arising  from  the  newly-created
municipal tax.

We also took legal action to challenge a City of São Paulo municipal law enacted in December 2002 that revoked
our blanket exemption from municipal taxes.  As a result of the loss of our exemption from municipal taxes, we may
be subject to a tax on services charged at a rate of 5.0% on our gross revenue from water and sewage services.  Our
request for an injunction against the municipality was granted by the trial court of the state of São Paulo (11a. Vara
da Fazenda Pública do Estado de São Paulo), and such injunction was maintained after the filing of an appeal by
the municipality.  However, on May 5 2005, the lower court issued a decision against us.  We intend to appeal such
decision  to  the  fullest  extent  permissible  by  law.    To  date,  we  have  not  established  a  provision  for  any  potential
expense arising from the loss of our exemption from municipal taxes.  We are currently in the process of estimating
the potential increase in our expenses in case the lower court’s decision is upheld.

In November 2004, we took legal action against the Municipality of Bragança Paulista against the imposition of a
new charge over the use of public areas for the installation of water and sewage mains for the provision of public
sanitation services.  On February 16, 2005, we were granted an injunction suspending the imposition of this charge
and preventing the municipality from collection of any current or future amounts due in respect of this change until
there  is  a  final  decision  on  the  merits.    As  of  the  date  of  this  annual  report,  no  decision  on  the  merits  has  been
reached.

We  cannot  predict  the  outcome  of  any  of  these  lawsuits  nor  can  we  assure  you  that,  in  the  event  of  an  adverse
decision, we will be able to pass through to our customers by increasing tariffs any increase in our deductions from
gross revenue, operating expenses or other expenses.

Condemnation Proceedings

We are party to a significant number of condemnation proceedings arising from the partial or total expropriation or
use of  private  property for water  mains,  sewer  lines  and  facilities.   Under  Brazilian  law,  the  State  or  the  relevant
municipality  is  entitled  to  condemn  private  property  to  the  extent  required  for  the  construction,  development  or
improvement  of  parts  of  water  and  sewage  systems  operated  by  us.    However,  we  are  required  to  provide
compensation to affected property owners based upon appraised fair market values.  Although we generally provide
compensation  to property owners on  the  basis of negotiated  settlements,  we  are party  to  many  lawsuits  related  to
compensation awards.  As of December 31, 2004, we estimated that we will be required to make payments totaling
R$280.0 million  with  respect  to  all  condemnation  matters.    We  do  not  believe  that  the  pending  condemnation
proceedings  will,  individually  or  in  the  aggregate,  have  a  material  adverse  effect  on  our  business,  results  of
operations, financial condition or prospects.

86

Other Legal Proceedings

We are party to a series of lawsuits initiated by the municipality of Ferraz de Vasconcelos in 1997, seeking payment
of  penalties  in  the  aggregate  amount  of  R$66.4 million,  which  we  allegedly  owe  for  damages  caused  during
construction in the municipality.  Several of these lawsuits have already been rejected by lower courts but are still
subject to appeal.  Although we are not able to predict the final outcome of the lawsuits, we believe that they will
not have a material adverse effect on our business, results of operations, financial condition or prospects.

In December 1997, the municipality of Santos enacted a law expropriating our water and sewage systems in Santos.
In  response,  we  filed  an  action  seeking  an  injunction  against  this  expropriation,  which  was  denied  by  the  lower
court.  This decision was later reversed by the Court of Appeals of the state of São Paulo, which issued a preliminary
order suspending that law.  On August 2, 2002, a decision on this matter was rendered in our favor by a lower court,
but  that  decision  remains  subject  to  appeal,  and we  can  give  no  assurance  that  the  ultimate  determination  will  be
favorable to us.  Despite the pending lawsuit, we continue to provide water and sewage services to Santos.

In  connection  with  discussions  we  had  with  the  municipality  of  Presidente  Prudente,  we  filed  a  suit  against  the
municipality seeking a court decision determining the continuation of the concession agreement that we have with
that municipality until the indemnification payment owed to us in connection with the return of water and sewage
system of the Presidente Prudente is made.  A final decision has not yet been rendered but the lower court has issued
a preliminary decision in our favor.

In addition, we are party to a number of proceedings with the Public Prosecution Office and several municipalities
which have contested our right to charge a tariff for sewage services provided as opposed to charging a fixed fee for
these services.  In most of these proceedings, we have received decisions in our favor.  We do not believe that the
final  outcome  of  these  proceedings  will  have  a  material  adverse  effect  on  our  business,  results  of  operations,
financial condition or prospects.

We are party to civil public actions brought by municipalities that seek cessation of the collection of fees relating to
sewage services, alleging that we do not treat the sewage in such municipalities and that we failed to make certain
investments  in  sewage  treatment  systems  as  provided  in  the  relevant  concession  agreements.    In  addition,  we  are
being  sued  by  the  Public  Prosecution  Office  of  the  state  of  São  Paulo  as  well  as  some  non-governmental
organizations  through  a  number  of  environmental  civil  public  actions  (i) aiming  to  enjoin  us  from  releasing
untreated  sewage  into  certain  local  water  courses,  and,  in  some  of  them,  (ii) seeking  remedies  for  environmental
damages,  which  have  not  yet  been  specified  and  evaluated  by  technical  experts  of  the  courts;  and  (iii) aiming  to
require us to install and operate sewage treatment facilities in those locations.  In each case, we are subject to daily
fines for noncompliance thereto.  In our response to these lawsuits we emphasize that the installation and operation
of sewage treatment facilities in those locations is included in our business plan and that the immediate cessation of
the  release  of untreated  sewage  into  the  relevant  local  water  courses  would  hinder  us  from  collecting  sewage  –  a
primary necessity – in those locations, causing much more damages against the environment and public health.  In
most of these lawsuits, no final judicial decision has been reached by local judges, yet.  Although we are not able to
predict the final outcome of these lawsuits, we believe that such outcome, even if unfavorable to us, would not have
a material adverse effect on our business, results of operations, financial condition or prospects.

Among  those  aforementioned  civil  public  lawsuits  are  the  following:    (A) The  Public  Ministry  of  the  State  has
brought a civil public action before the São Bernardo do Campo Court (5a. Vara Cível de São Bernardo do Campo)
which  seeks  reparation  for  and  cessation  of  environmental  damage  caused  by  us  dumping  sludge  from  our  water
treatment facilities into certain receiving waters.  A judge issued a preliminary order that we immediately cease such
dumping  and  established  a  daily  R$50,000  fine  for  not  complying  with  such  order;  however,  this  order  has  been
suspended  at  our  request.    Although  the  lower  court  has  issued  a  decision  in  our  favor,  this  decision  has  been
appealed.  We currently are unable to evaluate the extent or cost of any remedy that we may be held responsible for
in connection with this matter; (B) the Public Attorney of the Municipality of Paraguaçu Paulista has brought a civil
public action before the Paraguaçu Paulista Courts of Law (1a. Vara de Paraguaçu Paulista) which seeks reparation
for  and  cessation of  environmental  damage  allegedly  caused  by  our  release  of  raw  sewage  into  the  Alegre  River,
situated in the Municipality of Paraguaçu Paulista.  The lower court has issued a decision against us, requiring that
we (i) cease the release of raw sewage into the Alegre River, (ii) invest in a water and sewage treatment facility in

87

the Municipality of Paraguaçu Paulista; and (iii) pay an administrative penalty in the amount of R$116.9 million for
environmental  damage.    The  decision  also  imposes  a  daily  penalty  if  we  fail  to  comply  with  numbers  (i)  and  (ii)
above.  We have appealed this decision and such decision will not be effective until a final ruling is issued on this
appeal; and (C) A civil public action was brought against us by the Coordination Council for the Civil Entities of
Piracicaba  (Conselho  Coordenador  das  Entidades  Civis  de  Piracicaba)  concerning  the  limits  for  water  collection
from  the  Piracicaba  river  and  the  operation  of  the  Cantareira  water  distribution  system.    The  plaintiff  requests,
among other things, a prohibitory injunction in order to restrict the amount of water we collect, the reduction of the
Piracicaba river’s collection limit and the payment of damages to the riparian cities in order to cover the direct and
indirect environmental damages caused by the installation and operation of the Cantareira water distribution system.
We presented our defense in January 2004, alleging that the plaintiff has no standing to bring this action and that
some of the requests are inconsistent and/or impossible.  We also explained that the water collection limit was duly
authorized  by  law  and  by  the  competent  governmental  agency,  and  that  the  plaintiff  did  not  prove  or  specify  the
damages.  The injunction has not yet been considered, and this action is now awaiting judgment on the first instance.

We are also party to several administrative proceedings with CETESB – Companhia de Tecnologia de Saneamento
Ambiental (Environmental Sanitation Technology Company) seeking the imposition of penalties for environmental
damages  allegedly  caused  by  us  and  other  regulatory  matters.    However,  we  do  not  believe  that  the  final
determination  in  these  proceedings  will,  individually  or  in  the  aggregate,  have  a  material  adverse  effect  on  our
business, results of operations, financial condition or prospects.

Certain  construction  service  contractors  have  filed  claims  in  court  against  us  alleging  underpayment  of  inflation
indexation adjustments and monetary losses incurred in connection with introduction of the real.  Based on advice
from  our  legal  counsel,  and  due  to  new  claims  arising  in  2002,  we  increased  our  provision  for  these  claims  to
R$174.4 million in 2004 to meet probable losses arising from unfavorable decisions in these actions.

Approximately 680 lawsuits have been brought by our commercial customers that claim that their tariff rates should
be  equal  to  those  of  another  category  of  customers  and,  consequently,  seek  the  reimbursement  of  the  difference
between the amounts we charged and collected and those tariffs.  We have obtained final decisions both in favor and
against  us  in  these  lawsuits,  and,  as  of  December 31,  2004,  we  have  established  a  provision  in  the  amount  of
R$219.0 million with respect to these lawsuits.  We cannot predict, however, the amounts we would have to pay to
these customers if they were to prevail in their lawsuits, nor can we provide assurance that new lawsuits will not be
brought by other customers on similar grounds.  However, we do not believe that the final determinations in these
matters will, individually or in the aggregate, have a material adverse effect on our business, results of operations,
financial condition or prospects.

The  Association  of  Distinguished  Bars  and  Restaurants  (Associação  de  Bares  e  Restaurantes  Diferenciados  —
ABREDI)  has  initiated  several  lawsuits  to  challenge  the  10.0%  penalty  fee  we  charge  on  late  water  and  sewage
payments.  In several of these cases, lower courts have dismissed the lawsuits based on the lack of standing by the
plaintiff  to  initiate  such  a  lawsuit.    In  other  cases,  the  lawsuits  were  dismissed  because  a  civil  public  action  with
respect to the same matter was already being heard at the civil courts of the state of São Paulo.  Notwithstanding
these  legal  proceedings,  we  have  reduced  to  2.0%  the  penalty  fee  we  charge  on  late  bill  payments  by  all  of  our
customers.  Although we are not able to predict the final outcome of these lawsuits, we believe that they will not
have a material adverse effect on our business, results of operations, financial condition or prospects.

On October 29, 2003, the Public Attorney of the State (Ministério Público do Estado de São Paulo), on behalf of the
people of the state of São Paulo, brought a civil public action in a Trial Court of the state of São Paulo (12a. Vara da
Fazenda  Pública  do  Estado  de  São  Paulo)  alleging  that  a  transfer  to  us  of  ownership  of  the  Alto  Tietê  System
reservoirs from the State Department of Water and Energy of the State would be illegal.  An injunction against the
transfer of ownership of such reservoirs was granted but was later reversed.  However, in October 2004, the court
ruled in favor of the Public Attorney of the State, with respect to the illegality of the transfer of the reservoirs.  In
response, we filed an appeal which is pending final decision and the State successfully filed an action suspending the
lower Court’s decision until final judgment is reached by the Court of Appeals of the state of São Paulo (Tribunal de
Justiça do  Estado de São  Paulo).  We  are  unable  to  predict  whether  we  will  succeed  in  appealing  such  decision.
However, we currently do not expect that an eventual unfavorable decision would have a material adverse effect on
our business and financial condition.

In  December  1996,  we  commenced  legal  action  to  collect  payment  due  from  Diadema.    The  lower  courts  have
issued a decision against us and in November 2000 we appealed this decision.  As of April 2004 the appeal had not
yet  been  decided.    This  legal  action  was  followed  by  several  other  related  legal  proceedings,  some  of  which  are
currently pending.  A class action suit and an annulment action have been decided with favourable results for us.
We entered into a settlement agreement with Mauá at the time the concession was terminated in which Mauá agreed
to  make  the  payments  owed  to  us  in  connection  with  the return  of  water  and  sewage  systems.    However,  to  date
Mauá  has  not  yet  made  any  payments  to  us  under  the  settlement  agreement.    We  commenced  legal  action  in
December 1996 against Mauá and a decision was issued in February 2005 by the lower court requiring Mauá to pay
us the amount of R$153.2 million.  This decision is subject to appeal.  Diadema and Mauá are currently operating
their  own  water  and  sewage  systems,  and  we  are  supplying  them  with  water  on  a  wholesale  basis.    As  of
December 31, 2004, both Diadema and Mauá were in arrears with respect to amounts owed to us for water sold on a
wholesale basis prior to 1997, as well as for a portion of water sold since 1997.

On February 25, 2003, a request for a preliminary injunction was filed against us, restricting us from disposing of
sewage  without  due  treatment,  in  the  municipality  of  Lutécia.    The  injunction  also  determined  that  payments  for
water and sewage services by users be deposited with the court until we have made the necessary investment in the
water and sewage system of the municipality, in addition to paying a daily fine in the amount of R$300,000 (1000
minimum  salaries)  in  the  event  the  case  is  decided  against  us.    After  submission  of  an  expert  report,  the  Public
Prosecutor  Office  requested  that  we  be  sentenced  to  pay  the  amount  of  R$82.8  million.  In  anticipation  of  a
settlement  with  the  Public  Prosecutor  Office,  we  condemned  the  area  and  requested  the  respective  environmental
licenses for it.

On March 25, 2004, the Public Attorney’s Office filed a civil action against the Municipality of the City of Itapira,
its  mayor,  the  Municipal  House  of  Representatives  and  us,  claiming  that  Municipal  Law  No. 3,593/04  is
unconstitutional and seeking termination of the concession agreement we entered into with the Municipality of the
City of Itapira.  Although an injunction was granted, the São Paulo state Court of Appeals has stayed the injunction.
On March 23, 2005, the House of Representatives of Itapira approved a decree revoking the concession agreement.
In addition, Municipal Law No. 3,730/05 was enacted revoking an earlier law which authorized the municipality to
enter  into  the  concession  agreement  with  us.    The  municipality  of  Itapira  has  further  filed  an  action  against  us
aiming  to  repossess  the  assets  related  to  the  water  and  sewage  services  of  that  municipality  and  obtained  an
injunction to that effect.  At our request, that injunction was suspended and as a result, we are currently rendering
water and sewage services at Itapira.  As of the date of this annual report, the decision on this litigation was pending.

On October 10, 2003, the Municipality of Monte Mor filed a lawsuit against us, seeking the additional issuance and
delivery of shares by us, as consideration for our concession to render basic water and sewage services.  The lawsuit
was dismissed without judgment of its merits, but it is still subject to appeal.

The  Municipality  of  Sandovalina  has  brought  a  legal  action  against  us  aiming  to  (i)  obtain  the  termination  of  the
concession executed with us and (ii) seeking remedies for environmental damages and alleged losses caused to the
municipality due to our failure to provide sewage treatment, and other damages caused to public property.  We have
responded  with  a  counterclaim  requiring  the  municipality  to  pay  R$115,400  related  to  the  supply  of  water  from
December 1999 to August 2003.  We are also seeking  the  payment  of  a  contractual  indemnification based  on  the
early termination of the contract.  We are currently operating the water and sewage systems of Sandovalina, and the
lawsuit is still in the fact-finding phase.

On  April 11,  2003,  we  entered  into  an  agreement  with  the  Labor  Public  Attorney’s  office  called  the  Termo  de
Ajustamento de Conduta, or TAC.  Under this special agreement, we agreed to ensure that no construction work is
performed on our behalf by third parties using unregistered employees or without complying with safety regulations.
The agreement provides for a daily R$1,000 fine for non-compliance with these obligations.  The fine applies for
each worker laboring under irregular conditions or each clause under default, as the case may be.  The agreement is
enforceable by the Brazilian labor courts and is valid indefinitely.

We  are  party  to  a  substantial  number  of  other  legal  proceedings,  in  addition  to  the  lawsuits  and  administrative
proceedings discussed above, in the normal course of our business.  These legal proceedings include personal injury
and  property  damage  cases,  environmental  proceedings,  challenges  to  our  ability  to  cease  rendering  water  and

89

sewage services upon default by our customers and a range of other matters.  We have not established provisions
with respect to these other legal proceedings and do not believe  that  such  proceedings  will,  individually  or  in  the
aggregate, have a material adverse effect on our business, results of operations, financial condition or prospects.

conventional dispensers by gravity and have other pending applications at the INPI.

Software

We use software systems to manage our activities which we have acquired from vendors.  We have also developed
certain computer programs for management and control of water and sewage treatment plants, as well as for third-
party services management, called “AQUALOG,” “SGL” and “Electronic Price Quotation” (Cotação Eletrônica de
Preços), and have secured registration of these programs at the INPI and the agency of trademarks.  AQUALOG is
the only Brazilian software designed to monitor water treatment.  SGL (Bid Management System) is an electronic
price quotation system that allows us to view and control all bid and acquisitions proceedings in real time.

Dividends and Dividend Policy

Amounts Available for Distribution

At  each  annual  shareholders’  meeting,  the  board  of  directors  is  required  to  recommend  how  net  profits  for  the
preceding fiscal year are to be allocated.  For purposes of the Brazilian corporation law, net profits are defined as net
income  after  income  taxes  and  social  contribution  taxes  for  such  fiscal  year,  net  of  any  accumulated  losses  from
prior  fiscal  years  and  any  amounts  allocated  to  employees’  and  management’s  participation  in  our  profits.    In
accordance with the Brazilian corporation law, the amounts available for dividend distribution are the amounts equal
to our net profits less any amounts allocated from such net profits to:

•

•

the legal reserve; and

retained earnings for investment reserve.

We are required to maintain a legal reserve, to which we must allocate 5% of net profits for each fiscal year until the
amount for such reserve equals 20% of our paid-in capital.  However, we are not required to make any allocations to
our  legal  reserve  in  respect  of  any  fiscal  year  in  which  the  aggregate  amount  of  the  legal  reserve  plus  our  other
established capital reserves exceeds 30% of our capital.  Net losses, if any, may be charged against the legal reserve.
On  December 31,  2004,  the  balance  of  our  legal  reserve  was  R$172.0 million,  which  was  equal  to  5.1%  of  our
paid-in capital.

The  Brazilian  corporation  law  also  provides  for  two  discretionary  allocations  of  net  profits  that  are  subject  to
approval  by  the  shareholders  at  the  annual  meeting.    First,  a  percentage  of  net  profits  may  be  allocated  to  a
contingency reserve for anticipated losses that are deemed probable in future years.  Any amount so allocated in a

90

prior year must be either reversed in the fiscal year in which the loss was anticipated if such loss does not in fact
occur, or written off in the event that the anticipated loss occurs.  Second, if the mandatorily distributable amount
exceeds  the  sum  of  realized  net  profits  in  a  given  year,  such  excess  may  be  allocated  to  an  unrealized  revenue
reserve.  Under the Brazilian corporation law, realized net profits is defined as the amount of net profits that exceeds
the net positive result of equity adjustments and profits or revenues from operations with financial results after the
end of the next succeeding fiscal year.

Under  the  Brazilian  corporation  law,  any  company  may,  as  a  term  in  its  by-laws,  create  a  discretionary  reserve.
By-laws which authorize the allocation of a percentage of a company’s net income to the discretionary reserve must
also  indicate  the  purpose,  criteria  for  allocation  and  maximum  amount  of  the  reserve.    We  may  also  allocate  a
portion of our net profits for discretionary appropriations for plan expansion and other capital investment projects,
the  amount  of  which  would  be  based  on  a  capital  budget  previously  presented  by  management  and  approved  by
shareholders.  Under Law No. 10,313 of October 3, 2001, capital budgets for more than one year must be revised at
each  annual  shareholders’  meeting.    After  completion  of  the  relevant  capital  projects,  we  may  retain  the
appropriation until the shareholders vote to transfer all or a portion of the reserve to capital or retained earnings.  At
December 31, 2004, we had an investment reserve of R$1,691.4 million.

The  amounts  available  for  distribution  may  be  further  increased  by  a  reversion  of  the  contingency  reserve  for
anticipated losses constituted in prior years but not realized.  The amounts available for distribution are determined
on the basis of financial statements prepared in accordance with the Corporate Law Method.

The legal reserve is subject to approval by the shareholders voting at the annual meeting and may be transferred to
capital  but  is  not  available  for  the  payment  of  dividends  in  subsequent  years.    Our  calculation  of  net  profits  and
allocations to reserves for any fiscal year are determined on the basis of financial statements prepared in accordance
with the Corporate Law Method.

Mandatory Distribution

The Brazilian corporation law generally requires that the by-laws of each Brazilian corporation specify a minimum
percentage of the amounts available for distribution by such corporation for each fiscal year that must be distributed
to shareholders as dividends, also known as the mandatory distributable amount.  Under our by-laws, the mandatory
distributable  amount  has  been  fixed  at  an  amount  equal  to  not  less  than  25%  of  the  amounts  available  for
distribution, to the extent amounts are available for distribution.

The mandatory distribution is based on a percentage of adjusted net income, not lower than 25%, rather than a fixed
monetary  amount  per  share.    The  Brazilian  corporation  law,  however,  permits  a  publicly  held  company,  such  as
Sabesp, to suspend the mandatory distribution of dividends if the board of directors and the conselho fiscal report to
the shareholders’ meeting that the distribution would be inadvisable in view of the company’s financial condition.
The suspension is subject to approval of holders of common shares.  In this case, the board of directors must file a
justification for such suspension with the Brazilian securities commission.  Profits not distributed by virtue of the
suspension mentioned above shall be attributed to a special reserve and, if not absorbed by subsequent losses, must
be paid as dividends as soon as the financial condition of such company permits such payments.

Payment of Dividends

We are required by the Brazilian corporation law and by our by-laws to hold an annual shareholders’ meeting by the
fourth month after the end of each fiscal year at which, among other things, the shareholders have to decide on the
payment of an annual dividend.  The payment of annual dividends is based on the financial statements prepared for
the relevant fiscal year.  Under the Brazilian corporation law, dividends generally are required to be paid within 60
days  following  the  date  the  dividend  was  declared,  unless  a  shareholders’  resolution  sets  forth  another  date  of
payment, which, in either case, must occur prior to the end of the fiscal year in which the dividend was declared.  A
shareholder  has  a  three-year  period  from  the  dividend  payment  date  to  claim  dividends  (or  interest  payments  as
described under “— Record of Dividend Payments and Interest Attributed to Shareholders’ Equity”) in respect of its
shares,  after  which  the  amount  of  the  unclaimed  dividends  reverts  to  us.    The  depositary  will  set  the  currency

91

exchange date to be used for payments to ADS holders as soon as practicable upon receipt of those payments from
Sabesp.

Our by-laws do not permit us to pay interim dividends out of preexisting and accumulated profits for the preceding
fiscal year or semester.

In general, shareholders who are not residents of Brazil must register with the Central Bank to have dividends, sales
proceeds or other amounts with respect to their shares eligible to be remitted outside of Brazil.  The common shares
underlying our ADSs are held in Brazil by Banco Itaú S.A., also known as the custodian, as agent for the depositary,
which is the registered owner on the records of their registrar for our common shares.  Our current registrar is Banco
Itaú S.A. The depositary electronically registers the common shares underlying the ADSs with the Central Bank and,
therefore,  are  able  to  have  dividends,  sales  proceeds  or  other  amounts  with  respect  to  these  shares  eligible  to  be
remitted outside Brazil.  See “Item 10.  Additional Information—Regulation of Foreign Investment”.

Payments of cash dividends and distributions, if any, will be made in Brazilian currency to the custodian on behalf
of  the  depositary,  which  will  then  convert  such  proceeds  into  U.S.  dollars  and  will  cause  such  U.S.  dollars  to  be
delivered to the depositary for distribution to holders of ADSs.  See “Item 10. Additional Information—Regulation
of  Foreign  Investment”.    Under  current  Brazilian  law,  dividends  paid  to  shareholders  who  are  not  Brazilian
residents, including holders of ADSs, will not be subject to Brazilian withholding income tax, except for dividends
declared based on profits generated prior to December 31, 1995.  See “Item 10. Additional Information—Taxation”.

Record of Dividend Payments and Interest on Shareholders’ Equity

Brazilian corporations are permitted to distribute dividends in the form of a tax-deductible notional interest expense
on  shareholders’  equity  in  accordance  with  Law  No. 9,  249,  dated  December 26,  1995,  as  amended.    The  rate  at
which tax-deductible interest may be paid is limited to the product of the average Taxa de Juros de Longo Prazo –
TJLP (a long-term interest rate published by the Brazilian government) and shareholders’ equity during the relevant
period and cannot exceed the greater of:

•

•

50% of net  income  (before  taking  into  account  such distribution  and  any  deductions  for  income
taxes and after taking into account any deductions for social contributions on net profits) for the
period in respect of which the payment is made; and

50% of retained earnings.  Any payment of interest on shareholders’ equity to holders of ADSs or
common  shares,  whether  or  not  they  are  Brazilian  residents,  is  subject  to  Brazilian  withholding
income tax at the rate of 15% or 25% if the beneficiary is resident in a tax haven.  See “Item 10.
Additional Information—Taxation”.  The amount paid to shareholders as interest on shareholders’
equity,  net  of  any  withholding  tax,  may  be  included  as  part  of  any  mandatory  distributable
amount.  Under Brazilian law, we are obligated to distribute to shareholders an amount sufficient
to  ensure  that  the  net  amount  received  by  them,  after  payment  by  us  of  applicable  Brazilian
withholding taxes in respect of the distribution of interest on shareholders’ equity, is at least equal
to the mandatory distributable amount.  When we distribute interest on shareholders’ equity, and
that distribution is not accounted for as part of the mandatory distribution, Brazilian withholding
tax will apply.  All payments to date were accounted for as part of the mandatory distribution.

92

The following table sets forth the distributions out of net income that we made or will make to our shareholders in
respect of our 2001, 2002, 2003 and 2004 net income.  All these amounts distributed or to be distributed were or will
be in the form of interest on shareholders’ equity.

On February 26, 2004, December 16, 2004 and January 13, 2005, our Board of Directors approved the payment of
dividends,  in  the  form  of  interest  on  shareholders’  equity,  in  the  amount  of  R$39.3 million,  R$85.4  million  and
R$28.2 million respectively, to be paid within 60 days after our 2005 shareholders’ meeting.  We currently are not
able to determine the amount, if any, of its portion of these declared dividends that the State will apply to current
and future accounts receivable owed to us by the State or its controlled entities.

Dividend Policy

We  intend  to  declare  and  pay  dividends  and/or  interest  on  shareholders’  equity,  as  required  by  the  Brazilian
corporation law and our by-laws.  Our Board of Directors may approve the distribution of interest on shareholders’
equity, calculated based on our semiannual or quarterly financial statements.  The declaration of dividends is annual,
including dividends in excess of the mandatory distribution, and requires approval by the vote of the majority of the
holders of our common shares.  The amount of any distributions will depend on many factors, such as our results of
operations,  financial  condition,  cash  requirements,  prospects  and  other  factors  deemed  relevant  by  our  Board  of
Directors and shareholders.  Within the context of our tax planning, we may in the future continue determining that
it is to our benefit to distribute interest on shareholders’ equity.

In 2000, the Brazilian stock exchanges were reorganized through the execution of memoranda of understanding by
the  Brazilian  stock  exchanges.    Pursuant  to  the  memoranda,  all  securities  are  now  traded  only  on  the  São  Paulo
Stock Exchange, with the exception of electronically traded public debt securities and privatization auctions, which
are traded on the Rio de Janeiro Stock Exchange.  In 2001, 2002 and 2003, the São Paulo Stock Exchange accounted
for 100% of the trading value of equity securities on all Brazilian stock exchanges.

If  you  were  to  trade  in  our  common  shares  on  the  São  Paulo  Stock  Exchange,  your  trade  would  settle  in  three
business  days  after  the  trade  date  without  adjustment  of  the  purchase  price  for  inflation.    The  seller  is  ordinarily
required to deliver the shares to the exchange on the second business day following the trade date.  Delivery of and
payment for shares are made through the facilities of the clearinghouse, or Companhia Brasileira de Liquidação e
Custódia.

Each  Brazilian  stock  exchange  is  a  nonprofit  entity  owned  by  its  member  brokerage  firms.    Trading  on  each
exchange is limited to member brokerage firms and a limited number of authorized nonmembers.  The São Paulo
Stock Exchange has two open outcry trading sessions each day from 11:00 a.m. to 1:30 p.m. and from 2:30 p.m. to
5:45 p.m. Brazil local time, except during daylight savings time in the United States. During daylight savings time in
the United States, the sessions are from 10:00 a.m. to 1:00 p.m. and from 2:00 p.m. to 4:45 p.m. Brazil local time, to
closely mirror New York Stock Exchange trading hours.   Trading is also conducted between 11:00 a.m. and 6:00
p.m.,  or  between  10:00  a.m.  and  5:00  p.m.  during  daylight  savings  time  in  the  United  States,  on  an  automated
system known as the Computer Assisted Trading System (Sistema de Negociação Assistida por Computador) on the
São  Paulo  Stock  Exchange  and  on  the  National  Electronic  Trading  System  (Sistema  Eletrônico  de  Negociação
Nacional).    This  system  is  a  computerized  system  which  links  electronically  with  the  seven  smaller  regional
exchanges.  The São Paulo Stock Exchange also permits trading from 6:45 p.m. to 7:30 p.m., or from 5:30 p.m. to
7:00 p.m. during daylight savings time in the United States, on an online system connected to traditional and internet
brokers called the “After Market”.  Trading on the After Market is subject to regulatory limits on price volatility and
on the volume of shares transacted through internet brokers.  There are no specialists or officially recognized market
makers for our shares.

95

In order to better control volatility, the São Paulo Stock Exchange adopted a “circuit breaker” system pursuant to
which trading sessions may be suspended for a period of 30 minutes or one hour whenever the indices of these stock
exchanges  fall  below  the  limits  of  10%  or  15%,  respectively,  in  relation  to  the  index  registered  in  the  previous
trading session.

The São Paulo Stock Exchange is less liquid than the New York Stock Exchange or other major exchanges in the
world.  As of December 31, 2004, the aggregate market capitalization of the 390 companies listed on the São Paulo
Stock  Exchange  was  equivalent  to  approximately  US$341 billion  and  the  10  largest  companies  listed  on  the  São
Paulo Stock Exchange represented approximately 48.8% of the total market capitalization of all listed companies.
Although any of the outstanding shares of a listed company may trade on a Brazilian stock exchange, in most cases
fewer than half of the listed shares are actually available for trading by the public, the remainder being held by small
groups of controlling persons, by governmental entities or by one principal shareholder.  As of December 31, 2004,
we accounted for approximately 0.50% of the market capitalization of all listed companies on the São Paulo Stock
Exchange.

Trading  on  Brazilian  stock  exchanges  by  a  holder  not  deemed  to  be  domiciled  in  Brazil  for  Brazilian  tax  and
regulatory purposes (a  “non-Brazilian  holder”)  is  subject  to  certain  limitations  under  Brazilian  foreign  investment
legislation.    With  limited  exceptions,  non-Brazilian  holders  may  only  trade  on  Brazilian  stock  exchanges  in
accordance with the requirements of Resolution No. 2,689, of January 26, 2000, of the National Monetary Council.
Resolution No. 2,689 requires  that  securities held by non-Brazilian  holders be  maintained  in  the  custody  of,  or  in
deposit  accounts  with,  financial  institutions  duly  authorized  by  the  Central  Bank  and  the  Brazilian  securities
commission.  In addition, Resolution No. 2,689 requires non-Brazilian holders to restrict their securities trading to
transactions  on  Brazilian  stock  exchanges  or  qualified  over-the-counter  markets.    With  limited  exceptions,
non-Brazilian  holders  may  not  transfer  the  ownership  of  investments  made  under  Resolution  No. 2,689  to  other
non-Brazilian  holders  through  a  private  transaction.    See  “Item 10.  Additional  Information—Taxation— Brazilian
Tax Considerations— Taxation of Gains” for a description of certain tax benefits extended to non-Brazilian holders
who qualify under Resolution No. 2,689.

Novo Mercado

Since April 24, 2002, our shares have been listed on the Novo Mercado.  The Novo Mercado is a listing segment
under  the  São  Paulo  Stock  Exchange  designed  for  the  trading  of  shares  issued  by  companies  that  voluntarily
undertake  to  abide  by  some  additional  corporate  governance  practices  and  disclosure  requirements  in  addition  to
those already imposed by Brazilian law.  A company in the Novo Mercado must follow a series of corporate rules
known  as  “good  practices  of  corporate  governance”.    These  rules  generally  increase  shareholders’  rights  and
enhance the quality of information provided to shareholders.  On April 18, 2002, our shareholders approved changes
to our by-laws to comply with  the Novo Mercado requirements.   In  addition,  the  Novo  Mercado  provides for  the
creation  of  a  Market  Arbitration  Chamber  for  conflicts  resolution  between  investors  and  companies  listed  in  the
Novo Mercado.

In addition to the obligations imposed by current Brazilian law, a company listed on the Novo Mercado is obligated
to:

•

•

•

•

•

issue only voting shares;

hold public offerings of shares in a manner favoring diversification of the company’s shareholder
base and broader retail access;

maintain a minimum free float equal to 25% of the outstanding share capital of the company;

grant tag along rights for all shareholders in connection with a transfer of control of the company;

limit the term of all members of the board of directors to one year;

96

•

•

•

•

prepare annual and quarterly financial statements, including cash flow statements, in accordance
with U.S. GAAP or International Accounting Standards;

disclose  information  on  a  quarterly  basis,  including  insider  share  ownership  and  amount  of  free
float of shares;

if  it  elects  to  delist  from  the  Novo  Mercado,  hold  a  tender  offer  by  the  company’s  controlling
shareholder  (the  minimum  price  of  the  shares  to  be  offered  will  be  determined  by  an  appraisal
process); and

make greater disclosure of related party transactions.

Regulation of Brazilian Securities Markets

The Brazilian securities markets are principally governed by Law No. 6,385, of December 7, 1976, and the Brazilian
corporation  law,  each  as  amended  and  supplemented,  and  by  regulations  issued  by  the  Brazilian  securities
commission, which has regulatory authority over the stock exchanges and securities markets generally, the National
Monetary  Council,  and  by  the  Central  Bank,  which  has  licensing  authority  over  brokerage  firms  and  regulates
foreign  investment  and  foreign  exchange  transactions.    These  laws  and  regulations,  among  others,  provide  for
disclosure requirements applicable to issuers of traded  securities, protection of minority shareholders and criminal
penalties  for  insider  trading  and  price  manipulation.    They  also  provide  for  licensing  and  oversight  of  brokerage
firms  and  governance  of  the  Brazilian  stock  exchanges.    Nevertheless,  the  Brazilian  securities  markets  are  not  as
highly regulated and supervised as the U.S. securities markets.

Under the Brazilian corporation law, a company is either public (companhia aberta), such as we are, or closely held
(companhia fechada).  All public companies, including us, are registered with the Brazilian securities commission
and are subject to reporting requirements.  A company registered with the Brazilian securities commission may have
its  securities  traded  on  the  Brazilian  stock  exchanges  or  in  the  Brazilian  over-the-counter  market.    Our  common
shares  are  listed  and  traded  on  the  São  Paulo  Stock  Exchange  and  may  be  traded  privately  subject  to  some
limitations.

To  be  listed  on  a  Brazilian  stock  exchange  a  company  must  apply  for  registration  with  the  Brazilian  securities
commission and the stock exchange where the head office of the company is located.

We  have  the  option  to  ask  that  trading  in  our  securities  on  the  São  Paulo  Stock  Exchange  be  suspended  in
anticipation of a material announcement.  Trading may also be suspended on the initiative of the São Paulo Stock
Exchange or the Brazilian securities commission, among other reasons, based on or due to a belief that a company
has  provided  inadequate  information  regarding  a  material  event  or  has  provided  inadequate  responses  to  the
inquiries by the Brazilian securities commission or the São Paulo Stock Exchange.

The Brazilian over-the-counter market consists of direct trades between individuals in which a financial institution
registered  with  the  Brazilian  securities  commission  serves  as  intermediary.    No  special  application,  other  than
registration with the Brazilian securities commission, is necessary for securities of a public company to be traded in
this  market.    The  Brazilian  securities  commission  requires  that  it  be  given  notice  of  all  trades  carried  out  in  the
Brazilian over-the-counter market by the respective intermediaries.

Trading on the São Paulo Stock Exchange by non-residents of Brazil is subject to limitations under Brazilian foreign
investment and tax legislation.  The Brazilian custodian for the common shares underlying the ADSs must, on behalf
of the depositary for our ADSs, obtain registration from the Central Bank to remit U.S. dollars abroad for payments
of dividends, any other cash distributions, or upon the disposition of the shares and sales proceeds thereto.  In the
event that a holder of ADSs exchanges ADSs for common shares, the holder will be entitled to continue to rely on
the  custodian’s  registration  for  five  business  days  after  the  exchange.    Thereafter,  the  holder  may  not  be  able  to
obtain  and  remit  U.S.  dollars  abroad  upon  the  disposition  of  our  common  shares,  or  distributions  relating  to  our
common  shares,  unless  the  holder  obtains  a  new  registration.    See  “Item 10.  Additional  Information—Exchange
Controls—Regulation of Foreign Investment”.

97

ITEM 10. ADDITIONAL INFORMATION

The following is a summary of the material terms of our common shares, including related provisions of our by-laws
and the Brazilian corporation law.  This description is qualified by reference to our by-laws and to Brazilian law.

Corporate Purposes

We  are  a  mixed  capital  company  duly  organized  under  the  laws  of  Brazil  with  unlimited  duration.    We  have  the
legal status of a sociedade de economia mista, a mixed capital company with limited liability, operating under the
Brazilian corporation law.  As set forth in Article 2 of our by-laws, our corporate purpose is to plan, execute, and
operate basic sanitation services throughout the territory of the state of São Paulo, including the capture, adduction,
processing and distribution of water, as well as the collection, removal, processing and final disposal of sewage.

Description of Common Shares

General

Each common share entitles the holder thereof to one vote at our annual and special shareholders’ meetings.  The
Brazilian  corporation  law  requires  that  all  our  shareholders’  meetings  be  called  by  publication  of  a  notice  in  the
Diário  Oficial  do  Estado  de  São  Paulo,  the  official  government  publication  of  the  state  of  São  Paulo,  and  in  a
newspaper  of  general  circulation  in  our  principal  place  of  business,  currently  the  City  of  São  Paulo,  at  least
fifteen days prior to the meeting.  In addition, the Brazilian Securities Commission may also require the first call for
a shareholders’ meeting to be up to 30 days before such shareholders’ meeting.  The quorum to hold shareholders’
meetings on first call is generally 25% of the shares entitled to vote and on second call the meetings can be held with
the presence of any number of the shares entitled to vote.

Under  the  Brazilian  corporation  law,  our  common  shares  are  entitled  to  dividends  or  other  distributions  made  in
respect of our common shares in proportion to their share of the amount available for the dividend or distribution.
See “Item 8. Financial Information—Dividends and Dividend Policy” for a more complete description of payment
of  dividends  and  other  distributions  on  our  common  shares.    In  addition,  upon  any  liquidation  of  Sabesp,  our
common shares are entitled to return of capital in proportion to their share of our net worth.

In  principle,  a  change  in  shareholder  rights  of  shareholders,  such  as  the  reduction  of  the  compulsory  minimum
dividend, is subject to a favorable vote of the shareholders representing at least one half of our voting shares.  Under
some circumstances that may result in a change in the rights of shareholders, such as the creation of preferred shares,
the Brazilian corporate law requires the approval of a majority of the shareholders who would be adversely affected
by  the  change  present  in  a  special  meeting  called  for  such  reason.    The  Brazilian  corporate  law  specifies  other
circumstances where the dissenting shareholder may also have appraisal rights.

According to the Brazilian corporation law, neither a company’s by-laws nor actions taken at a general meeting of
shareholders may deprive a shareholder of some specific rights, such as:

•

•

•

•

•

the right to participate in the distribution of profits;

the  right  to  participate  equally  and  ratably  in  any  remaining  residual  assets  in  the  event  of
liquidation of the company;

the  right  to  supervise  the  management  of  the  corporate  business  as  specified  in  the  Brazilian
corporation law;

the right to preemptive rights in the event of a subscription of shares, debentures convertible into
shares or subscription bonuses  (except in some specific circumstances under Brazilian law); and

the right to withdraw from the company in the cases specified in the Brazilian corporation law.

98

Pursuant to the Brazilian corporation law and our by-laws, each of our common shares carries the right to one vote
at a general meeting of shareholders.  Sabesp may not restrain or deny that right without the consent of the holders
of a majority of the shares affected.

Neither the Brazilian corporation law nor our by-laws expressly addresses:

•

•

•

staggered terms for directors;

cumulative voting, except as described below; or

measures that could prevent a takeover attempt.

However, under the laws of the state of São Paulo and our by-laws, the State is required to own at least a majority of
our outstanding common shares.

According  to  the  Brazilian  corporation  law,  shareholders representing  at  least  one-tenth of  the voting  capital  may
request  that  a  multiple  voting  procedure  be  adopted  to  entitle  each  share  to  as  many  votes  as  there  are  Board
members  and  to give  each  shareholder  the  right  to  vote  cumulatively  for  only  one  candidate  or  to  distribute  their
votes among several candidates.  Pursuant to the Brazilian corporation law, shareholder action must be taken at a
shareholders meeting duly called and not by written consent.

Preemptive Rights

Each of our shareholders has a general preemptive right to subscribe for shares or securities convertible into shares
in any capital increase, in proportion to its shareholding, except in the event of the grant and exercise of any option
to acquire shares of our share capital.  A period of at least 30 days following the publication of notice of the issuance
of shares or securities convertible into shares is allowed for exercise of the right, and the right is negotiable.  Under
the Brazilian corporation law, we may amend our by-laws to eliminate preemptive rights or to reduce the exercise
period  in  connection  with  a  public  offering  of  shares  or  an  exchange  offer  made  to  acquire  another  company.
Currently our by-laws provide our shareholders with preemptive rights with respect to any offering.

In the event of a capital increase by means of the issuance of new shares, holders of ADSs, or of common shares,
would, except under circumstances described above, have preemptive rights to subscribe for any class of our newly
issued shares.  However, an ADS holder may not be able to exercise the preemptive rights relating to the common
shares underlying his or her ADSs unless a registration statement under the Securities Act is effective with respect to
those rights or an exemption from the registration requirements of the Securities Act is available.  See “Item 3. Key
Information—Risk  Factors—Risks  Relating  to  Our  Common  Shares  and  ADSs—A  holder  might  be  unable  to
exercise preemptive rights with respect to the common shares underlying our ADSs”.

Redemption and Rights of Withdrawal

The Brazilian corporation law provides that, under limited circumstances, a shareholder has the right to withdraw his
or her equity interest from the company and to receive payment for the portion of shareholder’s equity attributable to
his or her equity interest.  This right of withdrawal may be exercised by dissenting shareholders  of  Sabesp  in  the
event that at least half of all voting shares outstanding authorize us:

•

•

•

to create preferred shares;

to reduce the mandatory distribution of dividends;

to merge into another company or to consolidate with another company, subject to the conditions
set forth in the Brazilian corporation law;

99

•

•

•

•

•

•

to participate in a centralized group of companies as defined under the Brazilian corporation law
and subject to the conditions set forth therein;

to change our corporate purpose;

to split up, subject to the conditions set forth in the Brazilian corporation law;

to transform into another type of company;

to transfer all of our shares to another company or to receive shares of another company in order to
make  the  company  whose  shares  are  transferred  a  wholly  owned  subsidiary  of  such  company,
known as incorporação de ações; or

to acquire control of another company at a price which exceeds the limits set forth in the Brazilian
corporation law.

The right of withdrawal lapses 30 days after publication of the minutes of the shareholders’ meeting that approved
the  corporate  actions  described  above.    We  would  be  entitled  to  reconsider  any  action  giving  rise  to  withdrawal
rights within 10 days following the expiration of such rights if the withdrawal of shares of dissenting shareholders
would jeopardize our financial stability.  The Brazilian corporation law allows companies to redeem their shares at
their  economic  value,  subject  to  the  provisions  of  their  by-laws  and  certain  other  requirements.    Our  by-laws
currently  do  not  provide  that  our  capital  stock  will  be  redeemable  at  its  economic  value  and,  consequently,  any
redemption pursuant to the Brazilian corporation law would be made based on the book value per share, determined
on the basis of the last balance sheet approved by the shareholders.  However, if a shareholders’ meeting giving rise
to  redemption  rights  occurred  more  than  60  days  after  the  date  of  the  last  approved  balance  sheet,  a  shareholder
would  be  entitled  to  demand  that  his  or  her  shares  be  valued  on  the  basis  of  a  new  balance  sheet  dated  within
60 days of such shareholders’ meeting.

In  addition,  the  rights  of  withdrawal  in  the  third,  fourth  and  eighth  bullet  points  above  may  not  be  exercised  by
holders of shares if such shares (1) are liquid, defined as being part of the São Paulo Stock Exchange Index or other
stock  exchange  index  (as  defined  by  the  Brazilian  securities  commission),  and  (2) are  widely  held,  such  that  the
controlling shareholder or companies it controls have less than 50% of our shares.  Our common shares are included
on the São Paulo Stock Exchange Index.

This right of withdrawal may also be exercised in the event that the entity resulting from a merger, incorporação de
ações,  as  described above,  consolidation  or  spin-off of  a  listed  company  fails  to  become  a  listed  company  within
120 days of the shareholders’ meeting at which such decision was taken.

Arbitration

In connection with our listing with the Novo Mercado, we, our controlling shareholders, directors and officers have
undertaken to refer to arbitration any and all disputes or controversies arising out of the Novo Mercado rules or any
other  corporate  matters.    See  “—Market  Information”  above.    Under  our  by-laws,  any  disputes  among  us,  our
shareholders and our management with respect to the application of Novo Mercado rules, the Brazilian Corporate
Law, the application of the rules and regulations regarding Brazilian capital markets, will be resolved by arbitration
conducted  pursuant  to  the  BOVESPA  Arbitration  Rules  in  the  BOVESPA  Arbitration  Chamber.    Any  disputes
among  shareholders,  including  holders  of  ADSs,  and  disputes  between  us  and  shareholders,  including  holders  of
ADSs, will also be submitted to arbitration.

Options

There are currently no outstanding options to purchase any of our common shares.

100

Directors’ Powers

Although our by-laws contain no specific provisions regarding a director or executive officer’s power to vote on a
proposal, arrangement or contract in which that director has a material interest, under the Brazilian corporation law,
a  director  or  an  executive  officer  is  prohibited  from  voting  in  any  meeting  or  with  respect  to  any  transaction  in
which that director or executive officer has a conflict of interest with the company and must disclose the nature and
extent  of  the  conflicting  interest  for  transcription  in  the  minutes  of  the  meeting.    In  any  case,  a  director  or  an
executive officer may not transact any business with the company, including any borrowing, except on reasonable or
fair terms and conditions that are identical to the terms and conditions prevailing in the market or offered by third
parties.

Under our by-laws our shareholders are responsible for establishing the compensation we pay to the members of our
Board of Directors and the executive officers.

Pursuant to the Brazilian corporation law, each member of our Board of Directors must be a shareholder of Sabesp
and, pursuant to our by-laws, a resident of Brazil.  Our by-laws do not establish any mandatory retirement age limits.

See also “Item 6. Directors, Senior Management and Employees”.

Material Contracts

For a description of the material contracts entered into by Sabesp and the State, see “Item 7. Major Shareholders and
Related  Party  Transactions—Related  Party  Transactions—Transactions  with  the  State  of  São  Paulo—Agreements
with the State”.

Regulation of Foreign Investment

There are no restrictions on ownership of common shares by individuals or legal entities domiciled outside Brazil.
However,  the  right  to  convert  dividend  payments  and  proceeds  from  the  sale  of  common  shares  into  foreign
currency  and  to  remit  such  amounts  outside  Brazil  is  subject  to  restrictions  under  foreign  investment  legislation
which generally requires, among other things, the registration of the relevant investment with the Central Bank.

Under Resolution No. 2,689, foreign investors registered with the Brazilian securities commission may buy and sell
shares on the São Paulo Stock Exchange without obtaining a separate certificate of registration for each transaction.
Investors under these regulations are also generally entitled to favorable tax treatment.

Annex  V  to  Resolution  No. 1,289,  as  amended,  of  the  National  Monetary  Council,  also  known  as  the  Annex  V
Regulations,  provides  for  the  issuance  of  depositary  receipts  in  foreign  markets  in  respect  of  shares  of  Brazilian
issuers.

Following the closing of the sale of our ADSs in May 2002, an electronic certificate of registration was made in the
name  of  The  Bank  of  New  York,  as  the  depositary,  with  respect  to  such  ADSs  and  will  be  maintained  by  the
Brazilian  custodian  for  our  common  shares  on  behalf  of  the  depositary.    This  electronic  registration  is  carried  on
through the Central Bank Information System.  Pursuant to the registration, the custodian and the depositary are able
to convert dividends and other distributions with respect to  the  common  shares  represented  by ADSs  into foreign
currency  and  remit  the  proceeds  outside  Brazil.    In  the  event  that  a  holder  of  ADSs  exchanges  such  ADSs  for
common shares, the holder will be entitled to continue to rely on such electronic registration for five business days
after  the  exchange.    Thereafter,  unless  our  common  shares  are  held  pursuant  to  Resolution  No. 2,689  by  a  duly
registered investor, or, if not a registered investor under Resolution No. 2,689, a holder of common shares applies
for and obtains a new certificate of registration from the Central Bank, the holder may not be able to convert into
foreign currency and remit outside Brazil the proceeds from the disposition of, or distributions with respect to, our
common  shares,  and  the  holder,  if  not  registered  under  Resolution  No. 2,689,  will  be  subject  to  less  favorable
Brazilian  tax  treatment  than  a  holder  of  ADSs.    In  addition,  if  the  foreign  investor  resides  in  a  “tax  haven”
jurisdiction, the investor will be also subject to less favorable tax treatment.

101

See  “Item 3.  Key  Information— Risk  Factors—Risks  Relating  to  Our  Common  Shares  and  ADSs—If  a  holder
exchanges  ADSs  for  common  shares,  he  or  she  risks  losing  the  ability  to  remit  foreign  currency  abroad  and
Brazilian tax advantages” and “— Taxation—Brazilian Tax Considerations” below.

Taxation

This summary contains a description of certain Brazilian and U.S. federal income tax consequences of the purchase,
ownership and disposition of common shares or ADSs by a holder.

The summary is based upon the tax laws of Brazil and the United States as in effect on the date of this annual report,
which are subject to change, possibly with retroactive effect, and to differing interpretations.  Holders of common
shares  or  ADSs  should  consult  their  own  tax  advisors  as  to  the  Brazilian,  U.S.  or  other  tax  consequences  of  the
purchase, ownership and disposition of common shares or ADSs, including, in particular, the effect of any foreign,
state or local tax laws.

Although  there  presently  is  no  income  tax  treaty  between  Brazil  and  the  United  States,  the  tax  authorities  of  the
two countries have had discussions in the past regarding such a treaty.  No assurance can be given, however, as to if
or when a treaty will enter into force or how it will affect the U.S. holders of common shares or ADSs.

Brazilian Tax Considerations

The  following  discussion  summarizes  the  principal  Brazilian  tax  consequences  of  the  acquisition,  ownership  and
disposition of common shares or ADSs by a holder that is not domiciled in Brazil for purposes of Brazilian taxation
(a “non-Brazilian holder”).  It is based on Brazilian law as currently in effect, and, therefore, any change in such law
may change the consequences described below.  Each non-Brazilian holder should consult his or her own tax adviser
concerning the Brazilian tax consequences of an investment in common shares or ADSs.

A  holder  of  ADSs  may  withdraw  them  in  exchange  for  common  shares  in  Brazil.    Pursuant  to  Brazilian  law,
investors may invest in the common shares  under Resolution 2,689, of January 26, 2000, of the National Monetary
Council.

Resolution No. 2,689 allows non-Brazilian investors to invest in almost all financial assets and to engage in almost
all  transactions  available  in  the  Brazilian  financial  and  capital  markets,  provided  that  some  requirements  are
fulfilled.    In  accordance  with  Resolution  No.  2,689,  the  definition  of  non-Brazilian  investor  includes  individuals,
legal entities, mutual funds and other collective investment entities, domiciled or headquartered outside of Brazil.

Pursuant to Resolution 2,689, a foreign investor must:  (1) appoint at least one representative in Brazil with powers
to perform actions relating to the foreign investment; (2) complete the appropriate foreign investor registration form;
(3) register as a foreign investor with  the  Brazilian  securities  commission;  and (4) register  the  foreign  investment
with the Central Bank.

Securities  and  other  financial  assets  held  by  foreign  investors  pursuant  to  Resolution  2,689  must  be  registered  or
maintained in deposit accounts or under the custody of an entity duly licensed by the Central Bank or the Brazilian
securities commission. In addition, securities trading is restricted to transactions carried out in the stock exchanges
or  organized  over--the-counter  markets  licensed  by  the  Brazilian  securities  commission,  except  for  transfers
resulting from a corporate reorganization, occurring upon the death of an investor by operation of law or will or as a
consequence of  the delisting  of  the  relevant shares from  a  stock  exchange  and  the  cancellation  of  the  registration
with the Brazilian securities commission.

Taxation of Dividends

As a result of the tax legislation adopted on December 26, 1995, dividends based on profits generated after January
1, 1996, including dividends paid in kind, payable by us in respect of common shares, are exempt from withholding
income tax.  Stock dividends with respect to profits generated before January 1, 1996 are not subject to Brazilian
tax, provided that the stock is not redeemed by us or sold in Brazil within five years after distribution of such stock

102

dividends.  Dividends relating to profits generated prior to January 1, 1996 may be subject to Brazilian withholding
income tax at varying rates, depending on the year the profits were generated.

Taxation of Gains

Gains realized outside Brazil by a non-Brazilian holder on the disposition of ADSs to another non-Brazilian holder
are not currently subject to Brazilian tax. However, according to Law No. 10,833 of December 2003, or Law No.
10,833, the disposition of assets located in Brazil by a non-Brazilian holder, whether to other non-Brazilian holder
or  Brazilian  holders,  may  become  subject  to  taxation  in  Brazil.    Although  we  believe  that  the  ADSs  do  not  fall
within the definition of assets located in Brazil for the purposes of Law No. 10,833 , considering the general and
unclear  scope  of  it  and  the  lack  of  judicial  court  ruling  in  respect  thereto,  we  are  unable  to  predict  whether  such
understanding will ultimately prevail in the courts of Brazil.

The  withdrawal  of  ADSs  in  exchange  for  common  shares  is  not  subject  to  Brazilian  income  tax.    The  deposit  of
common shares in exchange for ADSs may be subject to Brazilian capital gain tax at the rate of 15% or 25%, in case
the holder is located in a “tax haven” (as described below), if the acquisition cost of the common shares is lower
than (1) the average price per common share on a Brazilian stock exchange on which the greatest number of such
shares were sold on the day of deposit, or (2) if no common shares were sold on that day, the average price on the
Brazilian stock exchange on which the greatest number of common shares were sold in the fifteen trading sessions
immediately preceding such deposit.  In this case, the difference between the acquisition cost and the average price
of the common shares, calculated as above, shall be considered a capital gain.

Non-Brazilian holders are generally subject to income tax imposed at a rate of 15% or 25%, in case the holder is
located in a “tax haven” (as described below) on gains realized on sales or exchanges of common shares that occur,
off of Brazilian stock, future and commodities exchanges.  Non-Brazilian holders are subject to income tax currently
at a rate of 15% on gains realized on sales in Brazil of common shares that occur on the Brazilian stock exchanges
unless such a sale is made by a non-Brazilian holder who is not resident in a “tax haven” (as described below) and:
(1) such sale is made within five business days of the withdrawal of such common shares in exchange for ADSs and
the  proceeds  thereof  are  remitted  abroad  within  such  five-day  period,  or  (2)  such  sale  is  made  under  Resolution
2,689 by registered non-Brazilian holders who obtain registration with the Brazilian securities commission.  In the
two latter cases, the gains realized are exempt from income tax. Such “gain realized” is the difference between the
amount  in  Brazilian  currency  realized  on  the  sale  or  exchange  and  the  acquisition  cost,  measured  in  Brazilian
currency, without any correction for inflation, of the shares sold.

Additionally,  the  transactions  with  the  common  shares  conducted  on  the  Brazilian  stock,  future  or  commodities
exchange  are  subject  to  a  withholding  income  tax  of  0.005%  on  the  value  of  the  sale  or  disposition  (to  be  offset
against tax due on eventual capital gains), except in case of non-Brazilian holder who is not resident in a “tax haven”
(defined below) and is registered under Resolution 2,689.

There  is  no  assurance  that  the  current  preferential  treatment  for  holders  of  ADSs  and  non-Brazilian  holders  of
common  shares  under  Resolution  2,689  will  continue  in  the  future  or  that  it  will  not  be  changed  in  the  future.
Reductions in the rate of tax provided for by Brazil’s tax treaties do not apply to the tax on gains realized on sales or
exchange of common shares.

Any exercise of preemptive rights relating to the common shares will not be subject to Brazilian taxation.  Any gain
on the sale or assignment of preemptive rights relating to the common shares by a holder of common shares or by
the depositary on behalf of holders of the ADSs, will be subject to Brazilian taxation at the same rate applicable to
the sale or disposition of common shares.

Interest Attributed to Shareholders’ Equity

Distribution of an interest on equity charge attributed to shareholders’ equity in respect of the common shares as an
alternative form of payment to shareholders who are either Brazilian residents or non-Brazilian residents, including
holders  of ADSs,  is  subject  to  Brazilian withholding  income  tax  at  the  rate  of  15%  or  25%,  in  case  the  holder  is
located  in  a  “tax  haven”  (as  described  below).    Such  payments,  subject  to  certain  limitations,  are  deductible  for

103

Brazilian income tax purposes and, as from 1997, deductible in determining social contribution on net income (the
latter is not applicable to us) by us as long as the payment of a distribution of interest is credited to the shareholder’s
account and approved at our general meeting of shareholders.

Beneficiaries Resident or Domiciled in Tax Havens or Low Tax Jurisdiction

Law  9779/99,  in  effect  as  of  January  1,  1999,  states  that,  with  the  exception  of  certain  prescribed  circumstances,
income derived from operations by a beneficiary resident or domiciled in a country considered as a “tax haven” is
subject to income tax withholding at a rate of 25%.  “Tax havens” are considered to be places which do not impose
any  income  tax  or  which  impose  such  tax  at  a  maximum  rate  of  less  than  20%  and  those  where  the  internal
legislation  imposes  restrictions  to  disclosure  of  the  shareholding  composition  or  the  ownership  of  the  investment.
Accordingly,  if  the  distribution  of  interest  attributed  to  shareholders’  equity  is  made  to  a  beneficiary  resident  or
domiciled  in  a  “tax  haven,”  the  income  tax  rate  applicable  will  be  25%  instead  of  15%.    Capital  gains  related  to
transactions not conducted in the Brazilian stock exchange (for “gains realized”) are subject to this 25% tax.  The
25%  rate  is  not  applicable  for  capital  gains  obtained  in  transactions  conducted  in  the  Brazilian  stock  exchange,
which remains subject to income tax at the rate of 15%.

Other Brazilian Taxes

There  are  no  Brazilian  inheritance,  gift  or  succession  taxes  applicable  to  the  ownership,  transfer  or  disposition  of
common shares or ADSs by a non-Brazilian holder, except for gift and inheritance taxes, which are levied by some
states of Brazil on gifts made or inheritances bestowed by individuals or entities not resident or domiciled in Brazil
within such states to individuals or entities resident or domiciled within such states in Brazil.  There are no Brazilian
stamp, issue, registration, or similar taxes or duties payable by holders of common shares or ADSs.

Tax on Bank Account Transactions (“CPMF”)

As  a general rule,  CPMF  is  imposed on  debits  to bank  accounts.    Therefore,  transactions  by  the  depositary  or  by
holders of common shares which involve the transfer of Brazilian currency through Brazilian financial institutions
shall  be  subject  to  a  financial  transactions  tax,  the  CPMF  tax.    The  CPMF  tax  is  a  temporary  contribution  on
financial transactions, at a current rate of 0.38%, despite the fact that, for some cases, transactions involving foreign
investors  may  be  exempt  from  CPMF.    The  responsibility  for  the  collection  of  the  CPMF  tax  is  borne  by  the
financial institution that carries out the relevant financial transaction.

Taxation of Foreign Exchange Transactions (IOF/Câmbio)

Pursuant to Decree 4,494/2000, IOF/Câmbio may be imposed on the conversion of Brazilian currency into foreign
currency  (e.g.,  for  purposes  of  paying  dividends  and  interest)  and  on  the  conversion  of  foreign  currency  into
Brazilian currency.  Except under specific circumstances, the rate of IOF tax on such conversions is currently 0%,
but the Minister of Finance has the legal power to increase at any time the rate to a maximum of 25%, but only in
relation to future transactions.

Tax on Bonds and Securities Transactions (IOF/Títulos)

Law 8,894/1994 created the Tax on Bonds and Securities Transactions, the IOF/Títulos, which may be imposed on
any transactions involving bonds and securities,  including  those  carried  out  on  Brazilian futures  and  commodities
stock exchanges.  As a general rule, the rate of this tax is currently zero, although the executive branch may increase
such rate up to 1.5% per day, but only with respect to future transactions.

United States Taxation

The discussion below is applicable to you only if you are a U.S. holder that is not domiciled in Brazil (or domiciled
or  resident  in  a  tax haven jurisdiction) for purposes of  Brazilian  taxation and,  in  the  case  of  a  holder  of  common
shares, that has registered its investment in common shares with the Central Bank as a U.S. dollar investment.  A
U.S. holder is a beneficial owner of a common share or ADS that is:

104

•

•

•

•

a citizen or resident of the United States;

a corporation or partnership created or organized in or under the laws of the United States or any
political subdivision of the  United States;

an estate the income of which is subject to United States federal income taxation regardless of its
source; or

a trust if it (1) is subject to the primary supervision of a court within the United States and one or
more  United  States  persons  have  the  authority  to  control  all  substantial  decisions  of  the  trust  or
(2) has a valid election in effect under applicable United States Treasury regulations to be treated
as a United States person.

Except where noted, this summary deals only with common shares or ADSs held as capital assets and does not deal
with special situations, such as those of banks, dealers in securities or currencies, traders in securities that elect to
use a mark-to-market method of accounting for their securities holdings, financial institutions, tax-exempt entities,
insurance companies, real estate investment trusts, regulated investment companies, persons holding common shares
or ADSs as part of a hedging, integrated, conversion or constructive sale transaction or a straddle, persons liable for
alternative  minimum  tax,  investors  in  a pass-through  entity, persons owning  10% or  more  of our voting  stock,  or
persons  whose  “functional  currency”  is  not  the  U.S.  dollar.    Furthermore,  this  discussion  set  forth  under  “United
States Taxation” is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and
regulations,  rulings  and  judicial  decisions  thereunder  as  of  the  date  hereof,  and  such  authorities  may  be  repealed,
revoked or modified so as to result in United States federal income tax consequences different from those discussed
below.  In addition, such summary is based, in part, upon representations made by the Depositary to us and assumes
that the deposit agreement, and all other related agreements, will be performed in accordance with their terms.

If a partnership holds common shares or ADSs, the tax treatment of a partner will generally depend upon the status
of the partner and the activities of the partnership.  If you are a partner of a partnership holding common shares or
ADSs, you should consult your tax advisors.

ADSs

In general, for United States federal income tax purposes, U.S. holders of ADSs will be treated as the owners of the
underlying common shares that are represented by such ADSs.  Deposits or withdrawals of common shares by U.S.
holders for ADSs will not be subject to United States federal income tax.  However, the United States Treasury has
expressed concerns  that  parties  involved  in  transactions wherein depositary  shares  are pre-released  may  be  taking
actions  that  are  inconsistent  with  the  claiming  of  foreign  tax  credits  by  the  holders  of  ADSs.    Accordingly,  the
analysis of the creditability of Brazilian taxes described herein could be affected by future actions that may be taken
by the United States Treasury.

Taxation of Dividends

The gross amount of distributions paid to you (including amounts withheld by the Brazilian taxing authority, if any,
and any payments of interest on shareholders’ equity, as described above under “—Brazilian Tax Considerations”)
will  be  treated  as  dividend  income,  to  the  extent  paid  out  of  our  current  or  accumulated  earnings  and  profits,  as
determined under United States federal income tax principles.  Such income may be included in your gross income
as ordinary income when actually or constructively received by you, in the case of common shares, or when actually
or  constructively  received  by  the  Depositary,  in  the  case  of  ADSs.    Such  dividends  will  not  be  eligible  for  the
dividends  received  deduction  allowed  to  corporations  under  the  Code.    To  the  extent  that  the  amount  of  any
distribution exceeds our current and accumulated earnings and profits for a taxable year, the distribution will first be
treated  as  a  tax-free  return  of  capital,  causing  a  reduction  in  the  adjusted  basis  of  our  common  shares  or  ADSs
(thereby  increasing  the  amount  of  gain,  or  decreasing  the  amount  of  loss,  to  be  recognized  on  a  subsequent
disposition of our common shares or ADSs), and the balance in excess of adjusted basis will be taxed as capital gain
recognized on a sale or exchange.

105

The  amount  of  any  dividend  paid  in  reais  will  equal  the  U.S.  dollar  value  of  the  reais  received  calculated  by
reference to the exchange rate in effect on the date the dividend is received by you, in the case of common shares, or
by the Depositary, in the case of ADSs, regardless of whether the reais are converted into U.S. dollars.  If the reais
received as a dividend are not converted into U.S. dollars on the date of receipt, you will have a basis in the reais
equal to their U.S. dollar value on the date of receipt.  Any gain or loss realized on a subsequent conversion or other
disposition of the reais will be treated as United States source ordinary income or loss.

Certain dividends received by certain non-corporate U.S. Holders through taxable years beginning on or before 31
December  2008  are  subject  to  a  reduced  maximum  tax  rate  of  15%  so  long  as  (i)  specified  holding  period
requirements are met, (ii) the U.S. Holder is not under an obligation (whether pursuant to a short sale or otherwise)
to  make  related  payments  with  respect  to  positions  in  substantially  similar  or  related  property,  (iii)  the  company
paying the dividend is a “qualified foreign corporation” and (iv)  the  company  is not a passive  foreign  investment
company for U.S. federal income tax purposes (a “PFIC”) in the year of distribution or the prior year.  We do not
believe that we were classified as a PFIC for our prior taxable year nor do we expect to be classified as a PFIC.  We
generally will be treated as a qualified foreign corporation with respect to our ADSs.  You should consult your own
advisor about the application of this rate to dividends paid directly on common shares.

Subject  to  certain  limitations,  Brazilian  withholding  taxes  on  dividends,  if  any,  may  be  treated  as  foreign  taxes
eligible for credit against a U.S. holder’s United States federal income tax liability.  For purposes of calculating the
foreign tax credit, dividends paid on our common shares will be treated as income from sources outside the United
States.  The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of
income.    Special  rules  apply  to  certain  individuals  whose  foreign  source  income  during  the  taxable  year  consists
entirely of “qualified passive income” and whose creditable foreign taxes paid or accrued during the taxable year do
not exceed US$300 (US$600 in the case of a joint return).  Further, a U.S. holder that (i) has held common shares or
ADSs for less than a specific minimum period during which it is not protected from risk of loss or (ii) is obligated to
make  payments  related  to  the  dividends  will  not  be  allowed  a  foreign  tax  credit  for  foreign  taxes  imposed  on
dividends paid on common shares or ADSs.  In addition, a U.S. holder that holds the shares in certain arrangements
in which the U.S. holder’s expected economic profits are insubstantial may not be allowed a foreign tax credit for
such foreign taxes.  The rules governing the foreign tax credit are complex.  You should consult your tax advisors
regarding the availability of the foreign tax credit under your particular circumstances.

Taxation of Capital Gains

For  United  States  federal  income  tax  purposes,  you  generally  will  recognize  taxable  gain  or  loss  on  any  sale,
exchange or  other  disposition  of  a  common  share or  ADS  in  an  amount  equal  to  the difference  between  the  U.S.
dollar value of the amount realized for the common share or ADS and your adjusted tax basis in the common share
or ADS, determined in U.S. dollars.  Such gain or loss will be capital gain or loss.  The capital gain or loss will be
long-term capital gain or loss if at the time of sale, exchange or other disposition you have held our common shares
or ADSs for more than one year.  Capital gains of individuals derived with respect to capital assets held for more
than  one  year  are  eligible  for  reduced  rates  of  taxation  depending  upon  the  holding  period  of  such  capital  assets.
The deductibility of capital losses is subject to limitations.  Any gain or loss recognized by you will generally be
treated  as  United  States  source  gain  or  loss.    Consequently,  a  U.S.  holder  may  not  be  able  to  use  the  foreign  tax
credit arising from Brazilian tax imposed, if any, on the disposition of a common share or ADS unless such credit
can be  applied  (subject  to  applicable  limitations)  against tax  due on other  income  treated  as  derived  from  foreign
sources.

Information Reporting and Backup Withholding

In general, information reporting requirements will apply to dividends in respect of our common shares or ADSs or
the proceeds received on the sale, exchange, or redemption of our ADSs, in each case to the extent treated as being
paid within the United States (and in certain cases, outside of the United States) to you unless you establish you are
an  exempt  recipient  (such  as  a  corporation),  and  backup  withholding  may  apply  to  such  amounts  if  you  do  not
establish you are an exempt recipient and you fail to provide a correct taxpayer identification number.  The amount
of any backup withholding from a payment to you will be allowed as a refund or credit against your United States
federal income tax liability provided you timely furnish the required information to the Internal Revenue Service.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Quantitative and Qualitative Disclosures about Market Risk

We  are  exposed  to  various  market  risks—in  particular,  foreign  currency  exchange  rate  risk  and  interest  rate  risk.
We  are  exposed  to  exchange  rate  risk  because  a  substantial  portion  of  our  financial  expenses  are  denominated  in
foreign  currencies  (primarily  the  U.S. dollar),  while  we  generate  all  of  our  net  operating  revenues  in  reais.
Similarly,  we  are  subject  to  interest  rate  risk  based  upon  changes  in  interest  rates,  which  affect  our  net  financial
expenses.

Exchange Rate Risk

At  December 31,  2004  and  2003,  approximately  R$2,680.9 million  and  R$3,012.7 million,  or  38.0%  and  41.5%,
respectively, of our debt obligations were denominated in foreign currencies  (including debt pegged  to baskets  of
foreign  currencies).    The  basket  of  foreign  currency-pegged  debt  consists  primarily  of  our  debt  with  the  Inter-
American  Development  Bank  and  the  World  Bank.    As  a  result,  we  are  exposed  to  exchange  rate  risks  that  may
adversely  affect  our  financial  condition  and  results  of  operations,  as  well  as  our  ability  to  meet  debt  service
obligations.  For example, we estimate that the potential loss to us in connection with U.S. dollar-denominated debt
that would have resulted as of December 31, 2004 and 2003 from each hypothetical instantaneous and unfavorable
1% change in the U.S. dollar against the real would have been approximately R$26.8 million and R$30.1 million,
respectively.    Consistent  with  these  estimates,  a  hypothetical  instantaneous  and  unfavorable  10%  change  in  this
exchange  rate  would  have  resulted  in  losses  of  approximately  R$268.1 million  and  R$301.2 million  as  of
December 31, 2004 and 2003, respectively.  These estimates do not take into account that the changes in exchange
rates comprising the baskets of foreign currencies often present variations different from the devaluation of the real
in relation to the U.S. dollar.

The devaluation of the real in relation to the U.S. dollar and with the Inter-American Development Bank and World
Bank basket of currencies, for the year ended December 31, 2004 were as follows:

Devaluation (appreciation) of real in relation to:

We have not utilized derivative financial instruments, although at times, we enter into forward exchange transactions
and financial funding transactions in reais to mitigate foreign currency exposure.

At December 31, 2004 and 2003, we had no short-term debt outstanding, other than the current portion of long-term
debt.

Interest Rate Risk

At  December 31,  2004  and  2003,  approximately  R$2,853.1 million,  or  65.3%,  and  R$2,993.9 million,  or  70.4%,
respectively,  of  our  total  debt  outstanding  balance  denominated  in  reais,  was  based  on  variable  rates  of  interest
based  on  the  Unidade  Padrão  de  Referência— UPR  (Reference  Standard  Unit),  which  is  equal  to  the  Taxa
Referencial—TR  (daily  government  interest  rate).    In  addition,  on  December 31,  2004  and  2003,  approximately
R$802.4 million,  or 18.4%,  and  R$1,026.2 million,  or 24.1%,  respectively, of  our  total  debt  denominated  in  reais
was subject to interest rates based on the Certificado de Depósito Interbancário, or CDI, rate (benchmark interest
rate set by the Brazilian interbank market on a daily basis).  At December 31, 2004 and 2003, R$1,055.8 million and
R$1,130.7 million,  respectively,  of  our  foreign-currency  denominated  debt  was  based  on  the  Inter-American
Development Bank and the World Bank variable rates of interest, which are determined based on the cost of funding
of these multilateral organizations in each period.

108

At December 31, 2004 and 2003, we did not have any derivative contracts outstanding which limited exposure to
changes  in  the  UPR  or  the  CDI  or  in  the  Inter-American  Development  Bank  or  World  Bank  variable  rates.
However,  we  are  obliged  by  law  to  invest  our  excess  cash  with  financial  institutions  controlled  by  the  Brazilian
government.    We  invest  these  excess  funds,  which  totaled  R$55.9 million  on  December 31,  2004  and
R$186.4 million  on December 31, 2003,  mainly  in  short-term  instruments.    As  a  result,  our  exposure  to  Brazilian
interest  rate  risk  is  partially  limited  by  our  real-denominated  floating  interest  time  deposits  investments,  which
generally  earn  the  CDI  rate.    In  addition  to  our  exposure  with  respect  to  existing  indebtedness,  we  may  become
exposed to interest rate volatility with respect to indebtedness incurred in the future.

We estimate that we would have suffered a loss over periods of one year, respectively, of up to R$8.0 million and
R$10.3 million  if  a  hypothetical  instantaneous  and  unfavorable  change  of  100  basis  points  in  the  interest  rates
applicable to financial liabilities on December 31, 2004 and 2003, respectively, had occurred.  Consistent with these
estimates,  a  hypothetical  instantaneous  and  unfavorable  10%,  or  1000  basis  point,  change  in  these  interest  rates
would have resulted in losses of approximately R$80.2 million and R$102.6 million as of December 31, 2004 and
2003, respectively.  This sensitivity analysis is based on the assumption of an unfavorable 100 basis point movement
of the interest rates applicable to each homogeneous category of financial liabilities and sustained over a period of
one year and that such movement may or may not affect interest rates applicable to any other homogenous category
of financial liabilities.  A homogeneous category is defined according to the currency in which financial liabilities
are  denominated  and  assumes  the  same  interest  rate  movement  within  each  homogeneous  category  (e.g.,
U.S. dollars).  As a result, our interest rate risk sensitivity model may overstate the effect of interest rate fluctuation
on these financial instruments, as consistently unfavorable movements of all interest rates are unlikely.

The tables below provide information about our interest rate-sensitive instruments.  For variable interest rate debt,
the  rate  presented  is  the  weighted  average  rate  calculated  as  of  December 31,  2004.    For  the  foreign  currency
denominated obligations these amounts have been converted at the selling rates at December 31, 2004, and do not
represent amounts which may actually be payable with respect to such obligations on the dates indicated.

ITEM 15. CONTROLS AND PROCEDURES

(a)

(b)

Based  on  their  evaluation  as  of  the  end  of  the  period  covered  by  this  annual  report,  the  chief  executive
officer  and  the  chief  financial  officer  of  Sabesp  have  concluded  that  as  of  such  date  Sabesp’s  disclosure
controls and procedures (as defined in Rules 13a-15(c) and 15d-15(c) under the U.S. Securities Exchange
Act  of  1934,  or  “Exchange  Act”)  are  effective  to  ensure  that  information  required  to  be  disclosed  by
Sabesp in reports that it files or submits under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified in Securities and Exchange Commission rules and forms.

There have been no significant changes in Sabesp’s internal control over financial reporting that occurred
during  the  year  ended  December  31,  2004  that  have  materially  affected,  or  are  reasonably  likely  to
materially affect, Sabesp’s internal control over financial reporting.

ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT

We have not established an audit committee, as defined under section 3(a)(58) of the Exchange Act.  Our board of
directors  and  fiscal  committee  are  deemed  our  audit  committee,  as  set  forth  by  the  Securities  and  Exchange
Commission in Release No. 33-8220 dated April 25, 2003.  As a result, our board of directors has determined that
we do not have an audit committee financial expert as defined for the purposes of this Item 16A.

ITEM 16B. CODE OF ETHICS

We currently do not have a code of ethics as such term is defined in Item 406(b) of Regulation S-K as we are not
required to have such a code of ethics under Brazilian law.  We are considering adopting a code of ethics in the near
future.

Pre-approval policies and procedures

Pursuant to Brazilian law, our Board of Directors is responsible, among other matters, for the selection, dismissal
and oversight of the external auditor.  Our management is required to obtain the Board of Directors’ approval before
engaging independent auditors to provide any audit or permitted non-audit services to us.  The Brazilian Federal and
State Public  Bidding  Laws  also  apply  to  us with  respect  to obtaining  services from  third parties  for our  business,
including  the  services provided by  our  independent  external  auditor.    As  part  of  the  bidding  process,  the  external
independent  auditing  firms  are  required  to  submit  proposals,  and  are  then  selected  by  us  based  on  certain  criteria
including technical expertise and cost.

During 2004, Deloitte Touche Tohmatsu did not provide non-audit services to us.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Management of
Companhia de Saneamento Básico do Estado de São Paulo - SABESP
São Paulo - SP

1. We have audited the accompanying balance sheets of Companhia de Saneamento Básico do Estado
de São Paulo - SABESP (a Brazilian Corporation hereinafter referred to as the “Company”) as of
December  31,  2004  and  2003,  and  the  related  statements  of  income,  changes  in  shareholders’
equity and changes in financial position for each of the two years in the period ended December 31,
2004.  These  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our
responsibility is to express an opinion on these financial statements based on our audits.

2. We  conducted  our  audits  in  accordance  with  the  standards  of  the  Public  Company  Accounting
Oversight  Board  (United  States).  Those  standards  require  that  we  plan  and  perform  the  audit  to
obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of  material
misstatement. The Company is not required to have, nor were we engaged to perform, an audit of
its  internal  control  over  financial  reporting.  Our  audits  included  consideration  of  internal  control
over  financial  reporting  as  a  basis  for  designing  audit  procedures  that  are  appropriate  in  the
circumstances  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the
Company’s internal control over financial reporting. Accordingly, we express no such opinion. An
audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and significant estimates made by
management,  as  well  as  evaluating  the  overall  financial  statements  presentation.  We  believe  that
our audits provide a reasonable basis for our opinion.

3.

In  our  opinion,  such  financial  statements  present  fairly,  in  all  material  respects,  the  financial
position of Companhia de Saneamento Básico do Estado de São Paulo - SABESP as of December
31, 2004 and 2003, and the results of its operations, changes in shareholders’ equity and changes in
financial position for each of the two years in the period ended December 31, 2004, in conformity
with accounting practices adopted in Brazil.

4. As mentioned in Note 6, the Company is negotiating with the State of São Paulo Government the
reimbursement of the amounts for supplementary retirement and pension paid by the Company and
the future flow of these payments to be reimbursed by State of São Paulo Government.

5. Accounting  practices  adopted  in  Brazil  vary  in  certain  respects  from  accounting  principles
generally  accepted  in  the  United  States  of  America.  The  application  of  the  latter  would  have
affected results of operations for each of the two years in the period ended December 31, 2004 and
the  determination  of  shareholders’  equity  as  of  December  31,  2004  and  2003,  to  the  extent
summarized in Note 23 to the financial statements.

We have audited the accompanying statements of operations, of changes in shareholders' equity
and of changes in financial position of Companhia de Saneamento Básico do Estado de São
Paulo─SABESP (the "Company") for the year ended December 31, 2002. These financial
statements are the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects,
the results of operations of the Company and the changes in its financial position for the year
ended December 31, 2002, in conformity with the accounting practices adopted in Brazil.

Accounting practices adopted in Brazil vary in certain significant respects from accounting
principles generally accepted in the United States of America. Information relating to the nature
and effect of such differences is presented in Note 23.

OPERATIONS

Companhia  de  Saneamento  Básico  do  Estado  de  São  Paulo  -  SABESP  (the  “Company”)  is
engaged  in  the  operation  of  public  water  and  sewage  systems  in  the  State  of  São  Paulo,
Brazil,  providing  water  and  sewage  services  to  a  broad  range  of  residential,  commercial,
industrial and government customers. The Company also provides water on a wholesale basis
to  certain  municipalities  in  the  São  Paulo  Metropolitan  Region  that  do  not  have  water
production systems.

The  Company’s  shares  are  listed  on  the  São  Paulo  Stock  Exchange  (BOVESPA)  in  the  “New
Market” segment since April 2002, and on the New York Stock Exchange (NYSE), in the form
of ADRs (American Depositary Receipts) since May 2002.

The  Company  provides  water  and  sewage  services  in  368  municipalities  in  the  State  of  São
Paulo, nearly all of which are through concessions granted by the municipalities. Most of these
concessions  have  30-year  terms,  seventeen  of  which  expire  in  2005  and  the  rest  between
2006 and 2034. Each of these concessions is automatically renewable for a period equal to its
initial  term,  unless  the  municipality  or  the  Company  exercises  the  right  to  terminate  the
concession, through notification by either party at least six months prior to its expiration date.

The Company does not hold a formal concession to provide water and sewage services in the
City of São Paulo, which accounts for a substantial portion of the sales and services rendered.
In  Santos,  a  municipality  located  in  the  Santos  Coastal  Area,  which  also  has  a  large
population,  the  Company  operates  under  a  public  authorization,  like  in  some  other
municipalities in the Santos Coastal Area and the Ribeira Valley, where the Company started
operating after the merger of the companies that formed SABESP.

PRESENTATION OF FINANCIAL STATEMENTS

The  Company’s  statutory  financial  statements,  which  are  used  as  the  basis  for  determining
income  taxes  and  mandatory  minimum  dividend  calculations,  have  been  prepared  in
accordance  with  accounting  practices  adopted  in  Brazil,  which  are  based  on  the  Brazilian
Corporate  Law  (Law  No.  6,404/76,  as  amended),  the  rules  and  regulations  of  the  Brazilian
Securities Commission ("CVM") and the accounting standards issued by the Brazilian Institute
of Independent Auditors (“IBRACON”), collectively referred to hereinafter as “Corporate Law”
or  “BR  CL”.  The  financial  statements  prepared  in  accordance  with  Corporate  Law  have  not
been indexed for inflation after 1995.

(a) 

Inflation accounting under BR CL

BR  CL  provided  a  simplified  methodology  for  accounting  for  the  effects  of  inflation  through
1995.  This  method  consisted  of  restating  permanent  assets  (property,  plant  and  equipment,
investments and deferred charges) and shareholders’ equity accounts using indices mandated
by  the  Brazilian  Federal  Government.  The  net  effect  of  these  restatements  was  credited  or
charged to the statement of operations.

(b) 

Presentation of financial statements

To  facilitate  an  understanding  of  Brazilian  accounting  practices,  the  presentation  of  the
financial  statements  has  been  adapted  from  the  financial  statements  filed  for  Brazilian  legal

F-10

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated)

and  regulatory  purposes.  In  addition,  certain  terminology  changes  have  been  made  and  the
notes  to  the  financial  statements  have  been  expanded  to  conform  them  more  closely  to
reporting  practices  prevailing  in  the  United  States  of  America.  All  amounts  are  presented  in
Brazilian currency (“real” or “reais”).

(c) 

Reclassifications

Certain  reclassifications  have  been  made  to  the  2003  and  2002  financial  statement
information  in  order  to  conform  them  to  the  2004  presentation.  These  reclassifications  have
been  made  as  management  believes  they  better  reflect  the  nature  of  items  and  improve
comparability.  These  reclassifications  had  no  effect  on  the  2003  and  2002  net  income  or
shareholders’ equity.

The most significant of these reclassifications include the following:

 (i)        Amounts  received  from  customers  in  duplicate  which  were  previously  classified  as  a
reduction to accounts receivable in the amount of R$59,444, has been reclassified as amounts
to be refunded to customers and are included under current liabilities and long-term liabilities,
in the amounts of R$ 3,677 and R$ 55,767, respectively, at December 31, 2003.

(ii)   PASEP credits, which were previously stated as a reduction of costs of sales, services and
operating  expenses,  have  been  reclassified  as  a  reduction  of  COFINS  and  PASEP  in  the
statements  of  income  in  accordance  with  IBRACON.  As  a  result  net  revenue  from  sales  and
services as well as costs and expenses have been increased. After the reclassification, the net
revenue of the Company in 2003 increased from R$ 4,109,884 to R$ 4,130,752, cost of sales
and  services  from  R$  2,046,834  to  R$  2,067,148,  selling  expenses  from  R$  297,302  to  R$
297,534 and administrative expenses from R$ 253,738 to R$ 254,060.

3.

SIGNIFICANT ACCOUNTING PRACTICES

The Company’s accounting practices, which are based on the accrual concept, comply with the
Corporate  Law  but  differ  in  certain  significant  respects  from  accounting  principles  generally
accepted in the United States of America (“US GAAP”). See Note 23 for further discussion of
the differences between BR CL and US GAAP and the reconciliation of shareholders’ equity and
net income (loss) between BR CL and US GAAP. Additional disclosure has been included in the
notes  to  the  financial  statements  to  comply  with  the  regulations  of  the  U.S.  Securities  and
Exchange Commission (the “SEC”) for foreign registrants.

(a)

Revenue from sales and services

Revenue for water and sewer services is recognized as water is consumed or as services are
provided.  Revenue  from  water  and  sewer  services  rendered  but  not  billed  is  recorded  as
unbilled  customer  accounts  receivable  based  on  monthly  estimates  in  order  to  match  such
revenue with costs incurred.

Revenue  is  recorded  net  of  applicable  taxes  and  customer  discounts,  including  discounts
related to the 2004 Incentive Program for Water Consumption Reduction (note 18 (a)).

(b)       Marketing costs

Marketing costs are generally expensed as incurred and reported in administrative expenses.
Marketing costs were R$ 31,615, R$ 4,206 and R$ 20,013 for the years ended December 31,

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated)

2004, 2003 and 2002, respectively. No marketing costs were deferred at December 31, 2004
and 2003.

(c)

Financial income and expenses

Financial income and expense are primarily comprised of interest and monetary and exchange
variations  on  loans  and  financing,  and  financial  investments,  calculated  and  reported  on  the
accrual basis of accounting.

(d)       Income and social contribution taxes

Income and social contribution taxes (a federally mandated tax based on income) are accrued
on taxable results At the applicable tax rates in effect.

Income tax is calculated at the rate of 15%, plus a 10% surtax, and social contribution, tax is
calculated at the rate of 9%. These taxes are reported on an accrual basis.

Deferred  taxes  are  recorded  for  temporary  differences  between  the  book  and  tax  bases  of
assets  and  liabilities.  The  deferred  tax  benefit  of  tax  loss  carryforwards  is  recognized  to  the
extent that realization is believed to be probable.

As permitted by the CVM, the Company opted not to recognize the deferred tax liability (non-
cash) on the revaluation reserve of property, plant and equipment recorded up to 1991.

(e)

Cash and cash equivalents

Cash  and  cash  equivalents  are  comprised  primarily  bank  deposits  and  financial  investments
and are carried at cost plus accrued interest, if applicable. Financial investments denominated
in  reais  have  a  ready  market  and  an  original  maturity  of  90  days  or  less.  These  comprise
mainly Financial Investment Funds (FIF’s). Foreign currency deposits, if any, are translated at
balance  sheet  date  exchange  rates.  The  Company  is  required  by  law  to  invest  excess  cash
with financial institutions controlled by the State Government.

(f)

Customer accounts receivable and allowance for doubtful accounts

Customer  accounts  receivable  generally  do  not  accrue  interest  or  indexation  charges  or
penalties, except for refinanced agreements (note 5).

An  allowance  for  doubtful  accounts  is  recorded  in  an  amount  considered  sufficient  by
management  to  cover  probable  losses  on  realization  of  customer  accounts  receivable  and  is
adjusted through charges or credits to selling expenses.  The Company records an allowance
for doubtful accounts for receivable balances in excess of R$ 5 and overdue for more than 360
days  and  in  excess  of  R$  30  and  overdue  for  more  than  360  days,  which  are  under  judicial
collection  proceedings.  For  accounts  receivable  balances  under  R$  5  and  overdue  more  than
180  days,  such  balances  are  written  off  through  a  direct  charge  to  income.    Recovered
amounts of previously written-off balances are recorded as a reduction of selling expenses.

(g)

Inventories

Inventories  of  materials  used  in  operations  and  in  the  maintenance  of  the  Company’s  water
and sewage systems are stated at lower of average acquisition cost or realizable value and are
classified in current assets. Inventories for capital projects are classified under property, plant
and  equipment  and  are  stated  at  the  lower  of  average  purchase/replacement  cost  and
realizable values.

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated)

(h)

Property, plant and equipment

Property,  plant  and  equipment  are  generally  stated  at  amounts  established  by  independent
technical  appraisals,  plus  price-level  restatements  from  the  date  of  the  appraisals  to  1995.
Revaluation increments arising from revaluing assets to appraised values are recorded in the
revaluation reserve component of shareholders' equity and subsequently transferred from the
reserve to retained earnings as the related assets are depreciated or upon disposal. The price-
level restatement adjustments were based on official inflation indices published by the federal
government.  The  Company  believes  that  the  distortion  caused  by  indices  which  understated
the  independently  measured  inflation  rate  have  been  mitigated  by  recording  revaluation
increments.

Contributions of property, plant and equipment by third parties and from government entities
(such  as  property  owners)  to  allow  the  Company  to  supply  water  and  sewage  services  are
recorded as a capital reserve.

Construction-in-progress  is  recorded  at  cost  and  is  primarily  related  to  construction  projects
under  contract  with  third  parties.  For  long-term  projects,  the  Company  capitalizes  these
projects  once  the  Company’s  engineering  department  approves  that  the  project  milestones
have been achieved and the Company takes delivery of the assets.

Depreciation

Depreciation  of  property,  plant  and  equipment,  is  recorded  using  the  straight-line  method
based on the estimated useful lives of the underlying assets. The principal depreciation rates
are detailed in Note 8.

Capitalization of interest

Up  to  1995,  BR  CL  did  not  require  the  capitalization  of  interest  costs  incurred  during  the
construction period as part of the cost of the related property, plant and equipment. However,
as permitted by the Brazilian Water and Sewage Plan (Plano Nacional de Saneamento Básico -
PLANASA),  the  Company  capitalized  interest  on  construction  in  progress  through  1988.  No
interest was capitalized from 1989 to 1995; interest was again capitalized beginning in 1996.
Beginning  in  1999,  capitalized  interest  includes  foreign  exchange  effects  and  indexation
charges.

Consistent with the requirements of  accounting  regulations for  Brazilian  utilities,  up  to  1985,
interest  was  capitalized  at  12%  per  annum  on  construction-in-progress.  Interest  capitalized
which  exceeded  interest  expense  on  loans  obtained  to  finance  construction-in-progress  was
recorded  in  a  capital  reserve  directly  in  shareholders'  equity.  Interest  capitalized  is
depreciated  with  the  cost  of  the  asset,  once  the  related  asset  becomes  operational.  Through
December  31,  1998,  but  not  thereafter,  such  depreciation  of  capitalized  interest  was
deductible  for  purposes  of  determining  taxes  on  income.  Following  changes  in  the  CVM
requirements in 1996, under BR CL, the Company capitalized interest during the construction
period and included the charge in property, plant and equipment.

The Company capitalizes interest incurred on borrowings to the extent that borrowings do not
exceed  construction-in-progress,  which  is  recorded  as  a  reduction  of  interest  expense.
Beginning in 1999, the Company has capitalized indexation charges on the real - denominated
loans and financing and the foreign exchange effects on foreign currency loans and financing.

Repairs and maintenance

Improvements to existing property are capitalized, while costs of maintenance and repairs are

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated)

expensed  as  incurred.  Materials  allocated  to  specific  projects  are  added  to  construction-in-
progress.

Concession assets acquired

As  of  December  1,  1998,  acquisitions  of  concession  assets  and  concession  rights  from  third
parties  have  been  accounted  for  at  fair  values,  as  determined  in  technical  appraisal  reports.
Accordingly, the purchase price, plus direct costs of acquisition, is allocated to assets acquired
and liabilities assumed based upon their estimated fair values at the date of acquisition. These
concessions are recorded as concession assets acquired, included as a component of property,
plant and equipment.

Concession assets are amortized on a straight-line basis over the estimated future periods to
be benefited, not to exceed the contractual term of the concession. The straight-line method
of depreciation is modified, when applicable, to avoid the backloading of charges in later years
by  estimating  future  disbursement  commitments  to  meet  the  Company’s  concession
obligations.

Impairment

The Company reviews long-lived assets, primarily buildings and water and sewage systems to
be held and used in the business, for the purpose of determining and measuring impairment
on  a  recurring  basis  or  when  events  or  changes  in  circumstances  indicate  that  the  carrying
value  of  an  asset  or  group  of  assets  may  not  be  recoverable.  The  Company  assesses
impairment on the basis of the projected recovery of depreciation charges through results of
operations. The carrying value of assets or groups of assets is written down to realizable value
if and when appropriate.

(i)

Deferred charges

Deferred  charges  are  comprised  primarily  of  deferred  project  costs  and  technical  studies,
which are being amortized using the straight-line method over 5 years.

(j)

Loans and financing

Loans and financing are adjusted by indexation charges and foreign exchange variations  and
include  accruals  for  related  interest  expenses.  Debt  denominated  in  foreign  currencies  are
translated  to  to  reais  using  the  exchange  rate  in  effect  at  the  balance  sheet  date.    The
resulting  foreign  currency  exchange  adjustments  are  recognized  as  incurred  in  financial
income (expense) , net.

(k)

Accrued payroll and related charges

Salaries,  provisions  for  vacation  pay,  including  supplementary  payments  negotiated  in
collective bargaining agreements and related social charges, are accrued as earned.

(l)

Provisions for contingencies

Provisions for  contingencies  are  recorded  at  the  estimated  amounts  to  cover  potential  losses
related  on  labor,  tax,  civil,  commercial,  environmental  and  other  claims  and  lawsuits,  when
such losses are considered probable and are estimateable by management.

(m)

Environmental costs

Costs  relating  to  ongoing  environmental  programs  are  expensed  as  incurred.  Ongoing

NOTES TO THE FINANCIAL STATEMENTS

programs  are  designed  to  minimize  the  environmental  impact  of  operations  and  to  manage
the environmental risks inherent to the Company’s activities. Provisions for contingent losses
related  to  environmental  claims  are  recorded  when  they  are  considered  to  be  probable  and
reasonably estimable by the Company’s management.

(n)

Pension and postretirement benefits

The  Company  sponsors  a  private  defined  benefit  pension  plan,  which  is  operated  and
administered  by  Fundação  SABESP  de  Seguridade  Social  (“SABESPREV”).    The  Company  is
accounting  for  the  actuarially-determined  liability  for  such  benefits  in  accordance  with  CVM
Resolution  371  of  December  13,  2000,  effective  as  of  January  1,  2002.    As  permitted,  the
Company  has  elected  to  recognize  the  transition  obligation  as  of  the  date  of  adoption  in
earnings on a straight-line basis over five years (see note 12).

(o)        Interest on shareholders’ equity

Brazilian  corporations  are  permitted  to  deduct  for  tax  purposes  interest  on  shareholders’
equity, which is a distribution similar to a dividend.  For financial reporting purposes, interest
on  shareholders’  equity  is  recorded  as  a  deduction  directly  from  unappropriated  retained
earnings.  Withholding taxes with respect to the payment of interest on shareholders’  equity
is paid by the Company on behalf of shareholders (see note 15).

(p)

Use of estimates

The  preparation  of  financial  statements  requires  management  to  make  estimates  and
assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities  and  the  reported
amounts of revenues and expenses for the reporting periods. Actual results could differ from
those estimates.

(q)       Earnings (loss) per share

This is calculated based on the number of shares outstanding at the balance sheet date.

payment history, that such amounts are better classified as long-term. The long-term portion
is  recorded  net  of  an  allowance  for  doubtful  accounts  of  R$  394,569  and  R$317,699  at
December 31, 2004 and 2003, respectively.

In  2003,  recoveries  included  R$129,118  of  previous  allowances  related  to  São  Bernardo  do
Campo, which were reversed in connection with the concession agreement reached in December
2003.

A  number  of  wholesale  customers  have  been  contesting  certain  tariffs  since  mid-1998.  As  a
result, some municipalities are currently not paying the Company’s invoices in full or on a timely
basis. In addition, some governmental entities located in municipalities the Company serves are
also not paying on a regular basis. While the Company continues to enter into negotiations with
municipalities  to  reschedule  the  related  accounts  receivable  and  continues  to  file  legal
proceedings  against  municipalities  to  collect  overdue  amounts,  in  some  cases,  the  Brazilian
courts  have  required  that  the  Company  continue  to  provide  water  on  a  wholesale  basis  to
municipalities, even if they fail to pay the Company’s invoices.

Management  believes  that  the  allowance  for  doubtful  accounts  is  sufficient  to  absorb  probable
losses in customer accounts receivable

Unbilled amounts

Unbilled  amounts  represent  water  and  sewage  services  provided  but  not  yet  billed,  which  are

The Company does not record an allowance  for  doubtful  accounts  for  any  amounts  due  from
the  State  Government  or  entities  controlled  by  the  State  Government,  since  it  does  expect
losses on such receivables.

(i)

Water and sewage services

The  Company  provides  water  and  sewage  services  to  the  State  Government  and  its  related
agencies under terms and conditions that management believes are equal to those with third
parties, except for the settlement of amounts outstanding, as described further below in items
(iii) and (iv).

(ii) 

Reimbursement for pension and benefits paid.

Reimbursement  for  pension  and  benefits  paid  represents  supplementary  pension  and  leave
benefit paid by the Company on behalf of the State Government to former employees of State
Government-owned  companies  which  merged  to  form  SABESP.  These  amounts  should  be
reimbursed  to  the  Company  by  the  State  Government,  as  the  primary  obligor,  in  conformity
with  Law  No.  200/74.  At  December  31,  2004  and  2003,  2,770  and  2,874  retirees,
respectively,  received  supplementary  pension  payments,  for  which  the  Company  paid  R$
85,340  and  R$  87,123  in  2004  and  2003,  respectively.  There  were  211  active  employees  at
December  31,  2004,  who  will  be  entitled  to  these  benefits  once  they  retire,  as  compared  to
225 at December 31, 2003.

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated)

(iii) GESP Agreement

On December 11, 2001, the Company entered into an agreement with the State of São Paulo
Government (the GESP  Agreement),  through  the  State  Department  of  Finance  and  the  State
Department  of  Water  and  Energy  (DAEE),  having  the  State  Department  of  Water  Resources,
Sanitation  and  Works  as  intervening  party.  Pursuant  to  the  GESP  Agreement,  the  State
Government,  by  force  of  Law  No.  200/74,  acknowledged  to  be  responsible  for  the
supplemental  retirement  and  pension  benefits  and  agreed  to  pay  amounts  it  owed  to  the
Company in respect of water and sewage services. The value to date of the Agreement was R$
678,830,  of  which  R$  320,623  refer  to  supplemental  retirement  and  pension  benefits  in  the
period  from  March  1986  until  November  2001,  and  R$  358,207  refer  to  water  supply  and
sewage collection services invoiced and due from 1985 until December 1, 2001.

The  GESP  Agreement  provides  that  the  Departamento  de  Águas  e  Energia  Elétrica—DAEE
(State  Department  of  Water  and  Energy)  will  transfer  to  the  Company  ownership  of  the
Taiacupeba,  Jundiai,  Biritiba,  Paraitinga  and  Ponte  Nova  reservoirs,  which  make  up  the  Alto
Tietê  systems,  and  the  fair  value  of  these  assets  will  reduce  the  amounts  owed  to  the
Company.  The  fair  value  of  these  reservoirs  has  been  based  on  the  arithmetic  average  of
independent  appraisals  performed  by  CPOS—Companhia  Paulista  de  Obras  e  Serviços  (a
State-owned  construction  company  selected  by  the  State  Government)  and  ENGEVAL—
Engenharia  de  Avaliação  (an  independent  appraisal  firm  selected  by  the  Company).  For
amounts due in excess of the agreed-upon fair value of the reservoirs, the State Government
will make payments in 114 consecutive monthly installments. The installments will be indexed
on  a  monthly  basis  by  the  IGP-M,  plus  an interest  rate  of  6%  per  year,  starting  on  the  date
the  first  installment  becomes  due.  Under  the  terms  of  the  agreement,  the  original  first
payment  was  to  have  been  made  by  July  2002,  but  has  been  postponed  pending  agreement
by  the  parties  on  the  fair  value  of  the  reservoirs  and  conclusion  of  the  audit  and  specific
analyses of amounts owed being performed by State Government-appointed advisors.

In July and August, 2002, the valuation reports of the two appraisers representing the  State
Government and the Company were presented. The arithmetic average of the fair value of the
reservoirs at June 30, 2002 was determined to be R$300,880, based on discounted cash flows
and reflecting the Company’s investments in the reservoirs.

Based  on  Official  Notice  No.  53/2005  of  the  State  Capital  Defense  Council  (CODEC),  dated
March  21,  2005,  negotiations  are  still  ongoing  between  the  Company  and  the  State
Government  with  a  view  to  restate  the  debt  for  supplementaly  retirement  and  pension
benefits,  under  the  terms  defined  in  the  GESP  agreement,  including  amounts  due  after
November 2001. It is anticipated that these negotiations will result in a second amendment to
the  GESP  Agreement.  The  Company  plans  to  retain  FIPECAFI  (“Fundação  Instituto  de
Pesquisas  Contábeis,  Atuariais  e  Financeiras,  USP”)  to  validate  the  actual  values  to  be
reimbursed by the State Government.

Once  the  amounts  and  any  monetary  adjustment  criterion  are  established,  Sabesp  believes
that  will  be  able  to  take  applicable  actions  with  the  DAEE  in  order  to  transfer  the  ownership
rights  to  the  Alto  Tietê  System  reservoirs.  The  Company  antecipates  that  this  second
amendment  will  also  include  the  criteria  for  monthly  recovery  of  any  future  amounts  to  be
disbursed by Sabesp.

Since  these  negotiations  are  still  in  the  early  stages,  it  is  not  possible  to  determine  the  net
effects on the balance sheet resulting from such negotiation. However, management does not
expect to incur significant net losses relating to any eventual differences between the amounts
recorded  as  due  from  the  State  Government  and  the  amounts  expected  to  be  received  by
Sabesp.

(iv)  First Amendment to GESP Agreement

On  March  22,  2004,  the  Company  and  the  State  Government  amended  the  terms  of  the
original GESP Agreement, thereby (1) consolidating and acknowledging amounts due from the
State Government for water and sewage services through February 2004, monetarily adjusted
through  February  2004;  (2)  formally  providing  for  the  offset  of  amounts  due  from  the  State
Government against interest on shareholders’ equity declared by the Company and any other
debt  owed  to  the  State  Government  at  December  31,  2003,  which  were  monetarily  adjusted
through  February  2004;  and  (3)  defining  the  payment  terms  of  the  remaining  obligations  of
the State Government for water and sewage services.

Under the terms of the Amendment, the State Government acknowledged amounts due to the
Company  for  water  and  sewage  services  provided  through  February  2004,  of  R$  581,779,
including monetary adjustments based on the  Referential  Rate  (TR)  at  the  end  of  each  fiscal
year  through  February  2004.  In  addition,  the  Company  acknowledged  amounts  due  to  the
State  Government  with  respect  to  interest  on  shareholders’  equity  of  R$  518,732,  including
(1) amounts declared and payable relating to years prior to 2003 (R$ 126,967), (2) monetary
adjustments  on  these  amounts  based  on  the  annual  change  in  the  Consumer  Prices  Index
(IPC/FIPE)  through  February  2004  (R$  31,098);  and  (3)  amounts  declared  and  payable
relating to 2003 (R$ 360,667).

The Company  and  the  State  Government  have  agreed  to  the  reciprocal  offset  of  R$  404,889
(monetarily  adjusted  through  February  2004).  The  remaining  obligation  of  R$  176,890  at
February 29, 2004 will be payable in monthly installments from May 2005 through May 2009,
which will be subject to monthly monetary adjustment at the Expanded Consumer Price Index
(IPCA/IBGE), plus 0.5%.

As  the  right  of  offset  was  contemplated  in  the  original  terms  of  the  GESP  Agreement,  the
Company recorded the applicable effects of such Amendment as of and through December 31,
2003,  including  the  monetary  adjustments  of  both  amounts  payable  to  and  receivable  from
the State Government. In addition, the amounts payable to the State Government for interest
on  shareholders’  equity  specifically  identified  in  the  agreement  for  reciprocal  offset  through
2004 have been reclassified as a reduction of amounts receivable at December 31, 2004.

The following summarizes the movement of the related accounts receivable from shareholder
related to water and sewage services and the  related  amounts  due  to  shareholder  related  to
interest  on  shareholders’  equity  reflecting  the  Amendment  as  of  and  for  the  years  ended

(c)

Arrangements to use certain reservoirs

The  Company  uses  the  Guarapiranga  and  Billings  reservoirs  and  a  portion  of  some  of  the
reservoirs of the Alto Tietê System, which are owned by the State Department  of  Water  and
Energy  (DAEE).  The  Company  does  not  pay  any  fees  with  respect  to  the  use  of  these
reservoirs,  but  is  responsible  for  maintaining  and  funding  the  operating  costs  of  these
reservoirs.  The State of São Paulo does not incur such costs on behalf of the Company. In the
event  these  facilities  had  not  been  made  available  to  the  Company,  it  would  have  had  to
obtain water from more distant sources which would have been more costly.

As part of these arrangements, the Company funded approximately R$97,115 of costs for the
1992  and  1997  projects.  A  portion  of  these  project  costs  were  funded  by  the  State
Government, through  DAEE. The agreements included the construction of ducts, tunnels and
other facilities to interconnect the Tietê River with the Biritiba and Jundiaí reservoirs and other
bodies of water in exchange for the Company’s use of the reservoirs during a 30-year period.

The  Company  has  the  right  to  draw  water  from  and  release  emissions  into  the  reservoirs
during  a  30-year  period  which  began  in  1997.  The  Company  capitalizes  expenditures  on  the
facilities  constructed.  The  assets  relating  to  the  original  reservoir  project  were  placed  in
service  in  1994  and  2002  and  are  being  depreciated  over  the  remaining  term  of  the  original
30  year  period.  The  Company  had  recorded  as  part  of  property,  plant  and  equipment
R$61,135  and  R$64,724  of  amounts  capitalized  with  respect  to  these  agreements,  net  of
accumulated depreciation, at December 31, 2004 and 2003, respectively .

(d)

Tariff reduction contracts

The Company has entered into contracts with approximately 5,000 State-owned entities under
which  it  provides  these  entities  with  a  25%  tariff  reduction  for  water  and  sewage  services
provided,  if  such  entities  implement  the  Company’s  program  for  the  rational  use  of  water,
which includes a reduction of at least 10% in water consumption.

Guarantees

(e)
The  State  Government  and  the  Brazilian  Federal  Government,  in  some  cases,  provide
guarantees of, or security for, the Company’s loans and financing.

7.

INDEMNITIES RECEIVABLE

Indemnities receivable represent amounts receivable from the municipalities of Diadema  and
Mauá  as  compensation  for  the  unilateral  withdrawal  by  those  authorities  of  the  Company’s
concessions for water and sewage services in 1995.

In  December  1996,  the  Company  filed  a  claim  seeking  compensation  for  investments  made
during  the  terms  of  the  concession  agreements.  Although  the  Company  has  not  yet  been
compensated  for  these  investments,  the  Company  continues  to  supply  water  on  a  wholesale
basis to these municipalities, which currently operate their own water distribution and sewage
collection systems.

The  net  book  value  of  property,  plant  and  equipment  items  relating  to  the  municipality  of
Diadema,  which  was  written  off  in  December  1996,  was  R$  75,231,  and  the  balance  of
indemnity  and  other  receivables  from  the  local  government  is  R$  62,876,  and  is  recorded  in
long-term assets, under “Indemnities receivable”.

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated)

The  net  book  value  of  property,  plant  and  equipment  items  relating  to  the  municipality  of
Mauá,  which  was  written  off  in  fiscal  year  1999,  was  R$  103,763,  and  the  balance  of
indemnity,  in  the  amount  of  R$  85,918,  is  recorded  in  long-term  assets,  under  “Indemnities

Both  cases  are  the  subject  matter  of  court  claims  and  the  legal  counsel  in  charge  of  the
proceedings believe that a favorable judgment is likely to be rendered to the Company.

In  relation  to  Mauá,  on  February  14,  2005  a  judgment  was  rendered  against  the  Local
Government  of  Mauá  and  Saneamento  Básico  do  Município  de  Mauá  –  SAMA,  which  were
sentenced  to  pay  to  the  Company  for  indemnity  for  the  investments  effected  in  that
municipality  during  the  term  of  the  concession  agreement,  the  amount  of  R$  153,245,  plus
loss of profits in the amount of R$ 5,309. This decision is still subject to appeal.

In relation to the municipality of Diadema, it has been determined that the declaratory action
of non-existing liability for trade acceptance bills should be attached to and heard jointly with
the  public  civil  action.  An  accounting  expert  examination  has  been  further  determined,  for
which the parties have submitted question to the court expert.

The Company has filed an appeal against the order that determined the joint judgment, which
is  pending  decision.  Thus,  the  attachment  of  the  action  and  the  preparation  of  the  expert
examination report are still pending in the records of the referred case.

In  relation  to  the  municipality  of  Diadema,  several  actions  have  been  filed  challenging  the
agreement  entered  into  between  the  parties.  Among  them,  the  class  action  and  the
annulment action have already been heard, with favorable judgment to the Company.

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated)

(a)

Disposals of property, plant and equipment

In  2004,  the  Company  wrote  off  property,  plant  and  equipment  items  in  the  amount
R$ 34,616  (R$ 61,657  in  2003  –  R$ 16,479  in  2002),  which  resulted  in  a  total  loss  of
R$ 34,440 (R$ 61,654 in 2003 – R$ 16,479 in 2002). Of these losses, R$ 26,034 (R$ 49,379
in 2003 – R$ 13,962 in 2002) related to the disposal, theft and obsolescence of assets in use.
The remaining balance of losses, of R$ 8,582 (R$ 12,275 in 2003 – R$ 2,517 in 2002) related
to  the  write-off  of  construction  in  progress  projects  which  were  determined  to  be  no  longer
economically feasible.

Studies  supporting  the  write-offs  for  obsolescence  and  construction-in-progress  were
concluded  by  the  Company  in  the  accounting  period  of  the  write-off,  based  on  undiscounted
cash  flow  projections,  and  have  been  approved  by  Management.  The  carrying  value  of
property,  plant  and  equipment  is  monitored  on  an  on-going  basis  and  is  adjusted,  when
appropriate, to assure future projected operating revenue is sufficient to recover the carrying
value  of  the  assets.  When  applicable,  depreciation  rates  are  adjusted  to  take  into  account
changes in estimated remaining economic lives as assets are replaced.

(b) 

Capitalization of interest and financial charges

The Company capitalized R$ 4,907 of interest and financial charges, including foreign currency
exchange variation, to property, plant and equipment for the year ended December 31, 2004,
during the period in which the related assets were under construction. With the appreciation of
Brazilian real in relation to other foreign currencies in which a portion of the Company’s debt is
denominated  (especially  the  United  States  dollar  –  US$),  R$  1,559  of  previously  capitalized
financial expenses were reversed in the year ended December 31, 2003.

(c)

Construction  in  progress  primarily  related  to  new  projects  and  operating  improvements  is  as

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated)

Estimated disbursements related to construction works already contracted are estimated to be
approximately R$ 817,000 for fiscal years from 2005 to 2010 (unaudited).

(d) 

Concession assets acquired

Since 1998, the Company has purchased the rights to provide water and sewage services in a
number of municipalities. The terms of these concessions are generally for a period of 30
years and generally include the corresponding right to operate the related concession assets
for which the Company does not have title. The purchase price for these concessions is
generally the fair value of the concession, based on appraisal reports which take into
consideration the projected cash flows and the remaining concession period at the date of
acquisition. The cost of the concession assets acquired is amortized over the concession
period.

The balance of concession assets, by municipality, was as follows:

Development  of  major  water  and  sewage  systems  frequently  requires  the  expropriation  or
establishment of rights of way through third-party properties. The owners of these properties
are  generally  compensated  either  through  negotiated  settlements  or  judicial  arbitration  in
conformity with applicable legislation.

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated)

Disbursements to be effected as from fiscal year 2005 for pending cases are estimated to be
approximately R$ 280,000 (unaudited), which will be paid out of Company funds. The related
assets  acquired  as  a  result  of  these  negotiations  are  recorded  as  property,  plant  and
equipment when the expropriation is complete. Aggregate disbursements for expropriations of
property, plant and equipment in 2004 wereas R$ 5,423 (R$ 5,499 in 2003).

(f)

Assets in guarantee

At  December  31,  2004  and  2003,  the  Company  had  assets  in  the  amount  of  R$  249,034
provided as guarantee under the Special Tax Debt Refinancing Program – PAES (Note 11).

(g)       Non-operational assets

The Company had R$ 31,903 at December 31, 2004 and 2003 of other non-operational
assets, comprised primarily of land surrounding reservoirs.

(h)         Revaluation

Property,  plant  and  equipment  items  were  revaluated  in  1990  and  1991  and  have  been
depreciated  at  annual  rates  which  take  into  consideration  the  estimated  remaining  economic
useful lives of the assets as determined in the respective  valuation  reports  that  generally  do
not exceed the original depreciable lives.

As  permitted  by  CVM  Instruction  197/93,  the  Company  did  not  post  a  provision  for  deferred
taxes on the surplus of the revaluation of property, plant and equipment carried out in 1990
and  1991.  Had  the  income  tax  and  social  contribution  on  the  revaluation  reserve  been
accounted for, the unrealized amount at December 31, 2004 would be R$ 491,475 (2003 – R$
526,900). In the years ended December 31, 2004 and 2003, the realized revaluation reserve
amounts were R$ 104,500 and R$ 134,245.

(i)          São Bernardo do Campo assets reclassification.

On December 19, 2003, the Company agreed to purchase the water and sewage assets of the
municipality  of  São  Bernardo  do  Campo,  thereby  obtaining  the  right  to  supply  water  and
sewage services.

The  value  of  the  concession  transaction  was  R$  415,471,  as  determined  based  on  an
independent appraisal, and was classified as “Intangible Assets”.

In  December  2004,  the  appraisal  of  the  assets  of  the  municipality  was  completed.  The
appraised  value  of  R$  175,858  was  reclassified  on  December  31,  2004  from  “Intangible
Assets” to “Property, plant and equipment in use”.

(Amounts in thousands of Brazilian reais-R$, unless otherwise indicated)

(a)

Banco do Brasil

In  March  1994,  existing  loan  agreements  with  Caixa  Econômica  Federal  were  refinanced
and the loan rights were transferred by that financial institution to the Federal Government,
with Banco do Brasil acting as an agent. Under the terms of the agreement signed with the
Federal Government, charges and payments are made on the “Price” amortization system,
indexed monthly to the Standard Reference Unit (UPR), which is equal to the Government’s
benchmark  Interest  Rate  (TR),  plus  interest  8.5%  per  year.  Interest  and  principal  are
payable monthly, with final maturity in 2014. This financing is guaranteed by the State of
São Paulo Government’s revenue and by the Company’s own revenues.

(b)

Debentures

(i)

3rd Issue

In  March,  1999,  the  Company  made  a  public  placement  of  413,094  non-convertible
debentures  in  an  aggregate  amount  of  R$  413,094,  with  original  maturity  in  November
2002. These debentures had an effective interest cost for the Company of CDI + 2.85% in
the  years  ended  December  31,  2004  and  2003.  In  September  2004,  the  Company

On  April  01,  2001  the  Company  made  a  public  placement  of  30,000  non-convertible,
registered, book-entry type, single series, non-renegotiable debentures, at the unit value of
R$  10,  in  an  aggregate  amount  of  R$  300,000.  The  placement  of  these  debentures  in  the
local market occurred through an auction held on June 8, 2001.

The amortization shall be made in 12 quarterly installments, beginning on March 15, 2004,
with final scheduled redemption date on December 15, 2006.

These  debentures  bear  interest  at  the  daily  interbank  deposit  rate  (DI),  as  calculated  and
disclosed  by  the  CETIP  (Securities  Custody  and  Financial  Settlement  Agency),  plus  1.20%
per annum spread. Interest is paid quarterly, having begun on June 15, 2001.

Funds  raised  from  the  issue  were  used  for  settling  debts  becoming  payable  in  the  funding
year.

In 2004, accrued interest was R$ 42,472 (2003 – R$ 68,297 and 2002 – R$ 57,295). The
outstanding  balance  payable,  in  the  amount  of  R$ 1,670,  is  recorded  under  “Loans  and
financing” in the current liabilities.

(iii)

5th Issue

On  April  1,  2002  the  Company  made  a  public  placement  for  the  5th  issue  of  simple,  book-

Tax effects on the revaluation of assets

As  permitted  by  CVM  Instruction  No.  197/93,  the  Company  did  not  record  deferred  tax
liabilities  related  to  the  adjustments  recorded  as  a  result  of  the  revaluations  of  property,
plant,  and  equipment  in  1990  and  1991.  These  unrecorded  deferred  tax  balances  would
have  amounted  to  R$ 491,475  at  December  31,  2004,  and  R$ 526,900  and  R$ 572,582
and at December 31, 2003 and 2002, respectively.

The  Company  had  tax  loss  carryfowards  of  R$ 484,950  at  December  31,  2004,  and
R$ 735,324  and  R$ 963,923  at  December  31,  2003  and  2002,  respectively,  related  to

expiration,  but  are  limited  to  utilization  of  30%  of  taxable  income  in  any  given  year.  The
Company is currently petitioning in court the right to fully offset the tax loss carryforwards
without  regard  to  the  30%  annual  limitation  imposed  by  Law  No.  8,981/95.  Utilization  of
tax loss carryforwards has been within the limitation established by law.

Pursuant to CVM Deliberation No. 273/98 and CVM Instruction No. 371/02, management is
required  to  present  its  best  estimate  of  expected  realization  of  tax  assets  arising  from
income  tax  and  social  contribution  tax  loss  carryforwards.  Current  estimates  indicate  that
these assets will be realized, as follows (unaudited):

 Year 

2005
2006
Total

Realization
      - %      

51,7
 48,3
100,0

In accordance with CVM Instruction No. 371/02, these estimates were based on projections
using the cash flow model, approved by the Company’s Board on March, 25, 2005.

However,  it  is  not  possible  to  foresee  with  reasonable  precision  the  years  in  which  the
assets  will  be  actually  realized.  The  estimates  for  the  generation  of  future  taxable  income
include  several  assumptions  related  to  the  performance  of  the  Brazilian  economy,  foreign
exchange rates, sales volumes, tariffs, tax rates and others, which could differ significantly
from current estimates. Management can provide no assurance that the tax assets will be
realized within the years specified above.

(e)

Deferral of tax on indexing gains (inflationary profit)

This balance arises from the inflation accounting system in use prior to 1996 through which
time  certain  adjustments  for  inflation  were  taxable  or  tax  deductible.  The  deferral  of  the
date of payment of income tax arising through that period was generally over the life of the
underlying  non-monetary  assets  but  not  exceeding  ten  years.  In  2002,  as  permitted  by
current tax legislation, the Company carried out a partial realization of inflationary profit in
advance  of  the  actual  timing  using  2002  tax  losses.  The  total  amounts  realized  during,
2003 and 2002 were R$9,903, and R$179,268, respectively.

participating employees, which were the following in the year:

Company: average of 6.89% (2003 – 6.21%) of on the payroll;
Participating employees:  3.21% of base salary and bonus, corresponding to 2.25% of the
gross payroll, on average.

(b) Pension benefits

Managed  by  Fundação  Sabesp  de  Seguridade  Social  –  SABESPREV,  the  defined  benefit
pension  plan  is  supported  by  monthly  contributions  as  follows:  2.10%  from  the  Company
and  2.19%  from  the  participating  employees.  In  order  to  meet  the  provisions  of  CVM
Resolution No. 371, of December 13, 2000, below is a description of the amounts of pension
and  retirement  benefits  paid  granted  and  payable,  to  which  the  employees  will  be  entitled
after their service time.

  (vii) Actuarial assumptions

Several  statistical  and  other  factors  that  attempt  to  project  future  events  are  used  in
calculating  the  expense  and  liability  related  to  the  plans.  These  factors  include  assumptions
about the discount rate, expected return on plan assets and the rate of future salary increases
as determined by the Company, within certain internal guidelines. In addition, the actuary also
uses  subjective  factors  such  as  termination,  turnover  and  mortality  rates  to  estimate  these
factors. The actuarial assumptions used by the Company are reviewed on a regular basis and
may  differ  materially  from  actual  results  due  to  changing  market  and  economic  conditions,
regulatory  events,  judicial  rulings,  higher  or  lower  termination/withdrawal  rates  or  longer  or
shorter  life  spans  of  participants.  Such  differences  may  result  in  a  significant  impact  on  the
amount of pension expense recorded by the Company.

The assumptions used for the actuarial valuation were as follows:

Increase in social security benefits and limits

As permitted by CVM Resolution No. 371, the Company has chosen to recognize, beginning
2002, over a period of five years, the actuarial liability of the pension plan of its employees
as of December 31, 2001, in the amount of R$ 266,074.

EMPLOYEE PROFIT SHARING AND OTHER BENEFITS

(a)

Employee Profit Sharing

The Company recorded additional salary and payroll charges in the amounts of R$40,262 ,
R$39,978, and R$34,740 for the years ended December 31,
2004,  2003  and  2002,  respectively,  relating  to  employees  profit  sharing,  in  accordance
with  the  labor  legislation  and  agreements  with  trade  unions.    Such  agreements  define
certain  targets  to  be  met  and  also  define  limits  for  distribution  per  employee  based  on
monthly salaries.  These charges represent an estimate made by management, as the final
determination of the amounts payable is not yet available at the date of the preparation of
the financial statements.

As a result of negotiations held by the Company with entities representing the employees,
a Profit Sharing Program was implemented for the period from July 2004 to June 2005,
with the payment of an amount corresponding to up to one month’s payroll, depending on
achievement of defined targets.  In December 2004 the Company made an advance
payment of R$20,717, equivalent to 50% of one month’s payroll.  The remainder of the
2004 accrual, if applicable, is estimated to be paid at the end of August 2005.

(b) 

Dismissal Encouragement Program

In  December  2003,  Company  management  approved  and  announced  a  special,  one-time,
dismissal encouragement program, granting special termination benefits to employees who
opted  for  termination  or  early  retirement.    Benefits  under  the  program  generally  included
30%  of  the  employee’s  salary  for  each  year  of  service  and  40%  of  the  FGTS  –  Fundo  de
Garantia por Tempo de Serviço (severance fund). Approximately 700 employees voluntarily
accepted  such  benefits  under  the  program.  At  December  31,  2003,  the  Company  accrued
R$ 34,645  for  these  benefits,  which  was  recorded  as  part  of  accrued  payroll  and  related
charges. All applicable  benefits were paid in July in 2004.

In  relation  to  contractor,  new  actions  were  filed  in  the  approximate  amount  of  R$  75
million, with monetary adjustment to the lawsuits in course of approximately R$ 58 million.

(i) 

Disputed taxes

-     Finsocial

In July 1991, the Company filed an Annulment and Declaratory Action (No. 91.0663460-5),
seeking  FINSOCIAL  debts  to  be  declared  null  and  void  and  the  Company’s  liability  to
contribute to FINSOCIAL to be extinguished. Deposits were made in court, at the 2% rate,
referring to the period from April 1991 until April 1992. On August 30, 2004, the Company
was  authorized  to  withdraw  75%  of  these  deposits.  The  remaining  25%  of  the  amount,
corresponding to the rate of 0.5%, was held as escrow deposit and a provision was posted
for such purpose. Upon the ruling by the Federal Supreme Court – STF that the FINSOCIAL
tax was applicable to the gross revenue of service providers, which in the understanding of
our  legal  counsel  has  effects  over  the  discussion  on  the  merit  by  the  Company,  the
Company settled the amount of R$ 57,016 on July 26, 2002, corresponding to 1.5% of the
total amount due, and requested the conversion into income,  to  the  benefit  of  the  Federal
Revenue  Service,  of  the  total  amount  deposited  in  court,  thus  terminating  lawsuit  No.
91.0663460-5, which is now in the formalization stage.

-     Tax on services

The Company took a legal action to challenge a City of São Paulo municipal law enacted in
December  2002  that  revoked  the  blanket  exemption  from  municipal  taxes.    As  a  result  of
the  loss  of  the  exemption from  municipal  taxes,  the  Company  may  be  subject  to  a  tax  on
services charged at a rate of 5.0% on gross revenue from water and sewage services.  The
Company requested for an injunction against the municipality was granted by the trial court
of the state of São Paulo (11a. Vara da Fazenda Pública do Estado de São Paulo), and such
injunction  was  maintained  after  the  filing  of  an  appeal  by  the  municipality.    However,  on
May 5 2005, the lower court issued a decision against the Company.  The Company intends
to  appeal  such  decision  to  the  fullest  extent  permissible  by  law.    A  provision  for  any
potential expense arising from the loss of exemption from municipal taxes was established.
The Company are currently in the process of estimating the potential increase in expenses
in case the lower court’s decision is upheld.

(ii)

Customer claims

Customer  claims  refer  to  actions  filed  by  the  Company’s  customers  claiming  tariff  parity
and,  consequently,  the  refund  of  amounts  imposed  and  charged  by  the  Company.  The
Company  has  obtained  final  decisions,  both  favorable  and  unforable,  in  the  lower  and
appellate courts, and has recorded provisions for cases with probable risk of loss.

(iii) 

Contractor claims

Certain  construction  service  contractors  have  filed  claims  in  court  against  the  Company
alleging underpayment of inflation indexation adjustments, withholding of amounts relating
to  the  effects  of  the  Real  Plan  and  economic-financial  unbalance  of  the  contract.  These
lawsuits  are  in  progress  in  lower  and  appellate  courts,  and  provisions  are  recorded  for
cases with probable chance of loss.

 Civil claims

Civil claims refer to indemnities for material damages, pain and suffering and loss of profits
caused  to  third  parties  and  which  were  brought  before  lower  and  appellate  courts.
Provisions have been recorded for cases with probable chance of loss.

In  November  2004,  the  Company  filed  a  petition  of  writ  of  mandamus  against  the
assessment and collection, by the Local Government of Bragança Paulista, of a fee for use
of streets for implementation and passage of urban equipment intended for providing urban
infrastructure  services,  seeking  to  obtain  a judgment  declaring  the  unconstitutionality  and
illegality  of  the  local  law  that  established  and  enacted  the  referred  fee.  On  February  16,
2005, the preliminary injunction was granted on the Company’s behalf, suspending liability
for the tax credits and for the fee for use of the areas until a final decision on the merit is
rendered  and  ordering  the  Local  Government  of  Bragança  Paulista  to  suspend  and  refrain
itself from demanding overdue or outstanding amounts allegedly due in conformity with the
local law under judgment. Up to this date, the writ of mandamus was pending decision by
the trial court.

(v)

Labor claims

The  Company  is  party  to  a  number  of labor  proceedings,  primarily  involving  the  Sindicato
dos Trabalhadores em Água e Meio Ambiente de São Paulo (“SINTAEMA”) such as matters
referring  to  overtime,  health  hazard  premium  claims,  prior  notice,  job  deviation,  salary
parity  and  others.  A  significant  portion  of  the  amounts  claimed  are  under  provisional  or
final  execution  stage,  in  several  different  court  levels,  and  thus  are  classified  as  probable
loss, and duly provided for.

On  January  9,  1990,  the  Water,  Sewage  and  Environment  Workers  Union  of  São  Paulo  –
SINTAEMA  filed  an  action  against  the  Company,  alleging  that  it  failed  to  pay  certain
benefits,  and  that  it  would  be  liable  for  the  payment  of  fine  to  the  SINTAEMA  under  the
terms  of  a  collective  bargaining  agreement  in  effect  at  that  time.  On  July  31,  1992,  the
Labor  Court  rendered  an  adverse  judgment  against  the  Company,  however  did  not  award
losses  and  damages  on  behalf  of  the labor  union  at  such  time.  Presently,  the  Company  is
negotiating  the  amount  to  be  paid  with  the  labor  union.  In  addition,  the  Company  filed  a
petition for writ of mandamus seeking a relief determining that the labor union is imposing
an  excessive  fine,  since  it  exceeds,  by  far,  the  principal  amount  of  the  debt.  The  request
has been denied by the trial court and the case is currently pending a definitive judgment
from the Superior Labor Court – TST.

(vi)      Environmental claims

Environmental  claims  refer  to  several  administrative  proceedings  brought  by  public
agencies,  including  Companhia  de  Tecnologia  de  Saneamento  Ambiental  –  CETESB
(Environment Sanitation Technology Company), seeking to impose a fine for environmental
damages allegedly caused by the Company.

Among  other  matters  involving  the  State  of  São  Paulo  Public  Attorney’s  Office,  the
following are worthy of mention: (A) On April 4, 2002, the Company was served process in
a  public  action  for  damages  caused  by  reason  of  disposing  of  sludge  from  the  Company’s
water treatment facilities into running water, determining that the Company should cease
to dispose of sludge and imposing a daily fine in the  amount  of  R$ 50,000.00  in  case  the
Company  did  not  comply  with  the  provisions  in  the  referred  preliminary  injunction;
however, such injunction was withdrawn. The trial court rendered an affirmative judgment
to the Company, against which an appeal has been filed. The Company is presently unable

to  estimate  the  extent  or  amounts  involved  in  connection  with  the  compliance  with
potential  measures  it  may  be  required  to  adopt  by  virtue  of  a  judgment  rendered  in  this
case  classified  as  probable  loss;  (B)  on  October  21,  2004,  a  trial  court  judgment  was
rendered  in  a  public  action  brought  by  the  Office  of  the  Public  Prosecutor  of  the  Judicial
District  of  Paraguaçu  Paulista  against  the  Company  on  February  17,  2003,  which  partially
granted  the  civil  public  action  and  sentenced  the  Company  to  (i)  refrain  itself  from
disposing of “in natura” sewage into any river in the Municipality of Paraguaçu Paulista; (ii)
invest in a water and sewage treatment system in this municipality; (iii) pay an indemnity
for environmental damages awarded in the amount of R$ 116,934, which was classified as
possible risk of loss. The court decision determined, further, that the non-compliance with
items  (i)  and/or  (ii)  above  will  subject  the  Company  to  the  payment  of  daily  fines.  The
Company  filed  an  appeal  against  the  trial  court  decision;  (C)  on  February  25,  2003,  a
request for a preliminary injunction was filed for the Company to immediately refrain itself
from disposing of sewage without due treatment, in the municipality of Lutécia, as well as
for  the  purpose  of  determining  that  payments  for  water  and  sewage  services  by  users
thereof  be  deposited  in  court  until  the  Company  has  fulfilled  the  necessary  plan  of
investments in the water and sewage system of the municipality, in addition to a daily fine
in  the  amount  of  one  thousand  (1,000)  minimum  salaries  in  case  of  non-compliance  with
the  award-making  decision.  After  submission  of  an  expert  report,  the  Public  Prosecutor
Office  requested  the  Company  to  be  sentenced  to  pay  the  amount  of  R$  82,779.  The
Company,  in  consideration  of  the  possibility  of  a  settlement  with  the  Public  Prosecutor
Office, condemned the area and requested the respective environment licenses.

Other Proceedings related to the Concession

On  December  2,  1997,  the  Municipality  of  Santos  enacted  a  law  expropriating  the
Company’s water and sewage systems in that municipality. In response, the Company filed
a petition for writ of mandamus added by a preliminary injunction against the enactment of
the referred law, seeking the annulment thereof. The preliminary injunction was denied by
the  trial  court.  Such  decision  was  further  reversed  by  the  State  of  São  Paulo  Court  of
Appeals, which granted the writ of mandamus suspending the effects of the  referred  law.
The trial court judge rendered an affirmative judgment to the Company, against which an
appeal was filed by the municipality of Santos. No final decision has been rendered up to
this  date  about  the  matter  by  the  Court  of  Appeals.  No  amount  was  record  on  December
31, 2004 and 2003.

The  Municipality  of  Sandovalina  brought  an  action  seeking  to  terminate  the  concession
agreement  entered  into  with  the  Company  and  to  sentence  the  Company  to  pay
contractual penalty as well as losses and damages for the supposed losses suffered by the
Municipality  on  account  of  the  absence  of  sewage  treatment  and  for  damages  caused  to
streets. The preliminary injunction for immediate reversal of the treatment of water in the
municipality  was  denied.  The  Company  challenged  the  case  and  filed  a  counterclaim
seeking the plaintiff to be sentenced to pay R$ 115 relating to water supply in the period
from  December  1999  to  August  2003,  as  well  as  to  pay  liquidated  damages,  without
prejudice  to  losses  and  damages  arising  out  of  the  Municipality  having  resumed  the
services.  The  Company  presently  continues  to  operate  the  water  and  sewage  systems  in
the Municipality of Sandovalina and the case is in the discovery stage of the proceeding.

shares, of which 1.43 billion were sold in Brazil and 3.84 billion were sold as 15.36 million
American Depositary Shares (“ADSs”) on the New York Stock Exchange - NYSE.

(c)

Distribution of earnings

Shareholders are entitled to a mandatory minimum dividend distribution of 25% of adjusted
net income, calculated in conformity with Brazilian Corporate Law.  This requirement can be
met through payments made in the form of dividends and interest on shareholders’ equity
(net  of  withholding  tax),  to  the  extent  amounts  are  available  for  distribution.  Dividend
distributions  are  limited  to  retained  earnings  as  determined  in  accordance  with  BR  CL.  At
December 31, 2004, as required by the CVM, management
designated  the  retained  earnings  balance  to  a  discretionary  investment  reserve  account
(see (e) below).

For  purposes  of  BR  CL,  and  in  accordance  with  the  by-laws  of  the  Company,  adjusted
annual  net  income  is  an  amount  equal  to  the  Company’s  annual  net  income  adjusted  to
reflect allocations to or from (i) statutory legal reserve, (ii) an equity contingency
reserve  for  anticipated  losses,  if  any,  and  (iii)  an  unrealized  revenue  reserve,  if  any.  The
calculation of the mandatory minimum dividends for 2004 is as follows:

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002
(Amounts in thousands of Brazilian reais-R$, unless otherwise indicated)

The Company by-laws also provide for distribution of interest on shareholders’ equity as an
alternative form of distribution to shareholders. The interest rate is limited to the variation
in  the  TJLP  during  the  applicable  period  and the  deductible  distribution  cannot  exceed  the
greater of 50% of net income (before distribution and deductions for income taxes) for the
period or 50% of retained earnings. Distribution of interest on shareholders’ equity is a tax-
deductible expense for both income tax and social contribution purposes. The amount paid
to shareholders as interest on shareholders’ equity, net of any withholding tax, is taken into
account in determining the mandatory dividend.

The Company declared interest on shareholders’ equity, in lieu of dividends, in the amount
of  R$  152,935,  R$504,089  and  R$108,222  during  the  years  ended  December  2004,  2003
and 2002, respectively, which include applicable amounts withheld as income tax related to
those shareholders who are subject to such taxation (State Government, municipalities and
pension  funds  among  others,  are  exempt  from  withholding  income  taxes).  Interest  on
shareholders’ equity was calculated in conformity with article 9 of Law No. 9,249/95, at the
Long-term  Interest  Rate  (TJLP).  This  interest  was  originally  recorded  in  “Financial
expenses”  for  income  and  social  contribution  tax  purposes  and  subsequently,  for
presentation purposes, was
reflected directly in “Shareholders’ equity” in conformity with CVM Deliberation No. 207/96.

As  discussed  in  Note  6,  the  remaining  balance  payable  to  shareholders  reflects  the
reclassification  to  receivable  from  shareholder  of  R$105,520,  R$401,712  at  December  31,
2004  and  2003,  respectively,    of  interest  on  shareholders’  equity  payable  to  the  State
Government, which will be subject to future reciprocal offset with amounts owed from the
State Government in accordance with the terms of the GESP Agreement as amended.

(d) 

Capital reserve

Capital reserve comprises of tax incentives and donations from government agencies.

The tax incentive reserve results from an option to invest in the capital stock of companies
undertaking  specified  government-approved  projects.  In  lieu  of  paying  part  of  the  income
tax due, the amount is credited to income tax and subsequently appropriated from retained
earnings to this reserve.

The  donations  reserve  reflects  the  value  of  assets  received  from  government  entities,
principally  enabling  the  Company  to  provide  service  access  to  properties.  No  shares  are
issued  in  exchange  nor  other  remuneration  provided  in  connection  with  assets  received.
These donations are recorded as a direct benefit to shareholders’ equity.

(e)       Investment reserve

Management  proposed  to  transfer  the  balance  of  retained  earnings  not  distributed  to
shareholders  to  a  discretionary  reserve  (investment  reserve)  in  accordance  with  the
Company’s capital expenditure program.

must  allocate  5%  of  the  adjusted  net  income  each  year  until  the  amount  of  the  reserve
equals 20% of paid-in capital.  Accumulated deficit, if any, may be charged

FINANCIAL INSTRUMENTS AND RISK

In  accordance  with  CVM  Instruction  No.  235/95,  the  Company  determined  the  market
values of its assets and liabilities based on available information and appropriate valuation
methodologies.  However,  both  the  interpretation  of  market  data  and  the  selection  of
valuation  methods  require  considerable  judgment  and  reasonable  estimates  in  order  to
produce  the  most  adequate  realization  value.  Consequently,  the  estimates  presented  do
not necessarily indicate the amounts which can be realized in the current market. The use
of different market approaches and/or methodologies could have a significant effect on the
estimated market values.

Market  values  and  book  values  of  the  Company’s  financial  instruments  at  December  31,
2004 and 2003 are as follows:

The  market  values  determined  by  the  Company  were  based  on  available  information  and
appropriate  valuation  methodologies,  both  of  which  require  considerable  judgment  and
estimates.  Consequently,  the  estimates  of  fair  values  presented  above  do  not  necessarily
indicate the amounts that might be realized or settled in a current market transaction. The
use of different market approaches and/or methodologies could have a significant effect on
the estimated market values.

(a)    Exchange rate risk

Exchange  rate  risk  is  the  risk  that  the  Company  may  incur  losses  due  to  exchange  rate
fluctuations,  which  could  increase  the  liability  balances  and  related  financial  expenses  of
loans  and  financing  denominated  in  foreign  currencies.  The  Company  does  not  enter  into
hedge  or  swap  transactions  to  mitigate  foreign  currency  risk,  given  the  amounts  and
related costs involved. However, at times, it enters into forward exchange transaction and
financial funding transactions in Brazilian reais to mitigate foreign currency exposure.

A  significant  portion  of  the  Company’s  debt  is  denominated  in  foreign  currency,  primarily
the US dollar and the Euro, totaling R$ 2,680,894 (note 9). The Company’s net exposure to
the exchange rate risk at December 31, 2004 and 2003 is summarized as follows:

(Amounts in thousands of Brazilian reais-R$, unless otherwise indicated)

(b)     Interest rate risk

Interest  rate  risk  is  the  risk  that  the  Company  may  incur  losses  due  to  interest  rate
fluctuations  that  would  increase  its  financial  expenses  related  to  loans  and  financing.  The
Company has not tradicionaly entered into derivatives transactions to mitigate interest rate
risk.  The  Company  does,  however,  continually  monitor  market  interest  rates  in  order  to
evaluate  the  possible  need  to  replace  or  refinance  its  debt.  On  December  31,  2004  and
2003,  the  Company  had  loans  and  financing  in  the  amount  of  R$  981,928  and  R$
1,225,090,respectively, at variable interest rates (CDI and TJLP).

Another risk faced by the Company is that adjustments to the Company’s related water and
sewage  tariff  rates  are  not  necessarily  correlated  with  the  increases  in  the  interest  rates
and price-level restatement indices associated with the Company’s debt.

(c)    Credit risk

The  Company  manages  credit  risk  principally  by  selling  to  a  geographically  dispersed
customer base, including sales to municipal governments.

No  single  customer  represented  more  than  10%  of  the  Company’s  sales  and  services
rendered in the years ended December 31, 2004, 2003, and 2002.

(d)     Drought weather risk

The  atypical  meteorogical  conditions  for  the  past  three  years,  resulted  in  the  need  to
launch  institutional  campaigns  to  encourage  economical  and  rational  use  of  water,  which
has led to a decrease in billed water volumes. At the same time, higher investments were
required to mitigate the drought effects on the Company’s water production systems. This
drought  period  has  required  a  reduction  in  water  supply,  with  a  consequent  reduction  in
water  volumes  billed.  In  view  of  the  present  levels  of  the  reservoirs,  no  rationing  is
estimated to occur in 2005.

(e)     Valuation of financial instruments

The  Company’s  main  financial  instruments  of  the  Company  as  of  December  31,  2004  and
the criteria adopted for their valuatuon are as follows:

(i) Cash and cash equivalents comprise cash on hand, bank accounts, financial investments
and  forward  exchange  transactions.  The  recorded  values  of  these  financial  instruments
approximate their market value.

(ii)  Loans  and  financing  and  debentures  -  Market  value  was  determined  based  on  the
discounted cash flows, using the interest rate projections available.

involving  advertisements  in  all  media,  together  with  a  program  consisting  of  discounts  to
customers  who  reduce  their  water  consumption  in  the  period  from  March  to  September
2004,  by  at  least  20%,  in  relation  to  the  average  consumption  determined  by  the
Company.  The  Incentive  Program  for  Water  Consumption  Reduction  was  implemented  in
the Metropolitan Region of São Paulo.

The  program  resulted  in  a  reduction  of  R$ 74.1  million  in  the  revenue  from  water  and

23. SUMMARY OF DIFFERENCES BETWEEN BR CL AND US GAAP

The  Company’s  primary  financial  statements  have  been  prepared  in  accordance  with  BR  CL
which differs significantly from US GAAP as described below:

(a) Inflation accounting methodology and indices

In Brazil, because of highly inflationary conditions which prevailed in the past, a form of
inflation  accounting  had  been  in  use  for  many  years  to  minimize  the  impact  of  the
distortions  in  financial  statements  caused  by  inflation.  Two  methods  of  inflation
accounting  were  developed:  one  required  under  BR  CL;  and  the  other  known  as  the
Constant  Currency  Method.  The  primary  difference  between  BR  CL  and  the  Constant
Currency Method relates  to  accounting  for  the  effects  of  inflation.  Under  BR  CL, inflation
accounting was discontinued effective January 1, 1996. Prior to that date, BR CL required
inflationary  indexation  of  property,  plant  and  equipment,  investments,  deferred  charges
and  shareholders'  equity,  the  net  effect  of  which  was  reported  in  the  statement  of
operations  as  a  single  line  item.  The  Constant  Currency  Method  is  similar  to  U.S.
Accounting Principles Board Statement No. 3 ("APS 3"), except that the former continues
to  apply  inflationary  accounting in  periods  of low  inflation.  Under  US GAAP,  the  Brazilian
economy  ceased  to  be  highly  inflationary  effective  July  1,  1997.  The  other  significant
difference  between  the  two  sets  of  principles  relates  to  the  present-value  discounting  of
fixed-rate  receivables  and  payables,  which  is  required  by  the  Constant  Currency  Method
and is prohibited under BR CL.

Financial  statements  prepared  in  accordance with  BR  CL  have  been,  and  continue  to  be,
required of all Brazilian corporate entities and are used by the Brazilian tax authorities in
determining  taxable  income.  Financial  statements  prepared  in  accordance  with  the
constant currency method were required through 1995 for those entities whose securities
were  registered  with  the  CVM.  Since  1996,  presentation  of  supplemental  financial
statements under the Constant Currency Method has been optional.

(i) Additional inflation restatement in 1996 and 1997 for US GAAP

In  the  reconciliation  from  BR  CL  to  US  GAAP,  consistent  with  the  position  paper
prepared  by  the  U.S.  AICPA  International  Practice  Task  Force,  an  adjustment  for
inflation  accounting  has  been  included  for  the  period  from  January  1,  1996  to
December 31, 1997. During this period, inflation accounting was prohibited by BR CL
but was required by APB statement 3 under US GAAP. Shareholders' equity under US
GAAP was increased by R$ 1,309,072 and R$ 1,379,323 at December 31, 2004 and
2003, respectively,  due to the additional inflation restatement adjustments.

(ii) Supplementary  inflation  restatement  replaces  revaluation  of  property,  plant  and

equipment for US GAAP

The  price-level  restatement  methodology  under  BR  CL  relied  on  an  official  inflation
index  announced  by  the  Brazilian  Federal  government  which  was  also  used  for
purposes  of  determining  taxes  payable.  Shortly  after  the  launch  of  an  economic
stabilization plan in 1990, the government announced an inflation rate for that year
which  was  materially  understated  in  relation  to  the  general  and  consumer  price

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002
(Amounts in thousands of Brazilian reais-R$, unless otherwise indicated)

indexes as measured by independent economic institutes. In 1991, the government
acknowledged  this  distortion  and  companies  were  required  to  re-present  their
statutory financial statements using a revised inflation index and the effects thereof
were  also  used  to  determine  income  taxes,  retroactively.  The  same  law  (Law No.
8,200/91) also granted companies the option (and the CVM required adoption when
the effects were significant) to reprocess the accumulated inflation accounting effects
since the date of acquisition of assets based on an independently sourced consumer
or  general  price  index.  This  supplemental  indexation  of  property,  plant  and
equipment, investments and deferred charges was to be recorded in the statutory BR
CL  accounting  books  but  would  have  no  effect  for  tax  purposes.  The  Company
anticipated the effects of this measure by contracting an independent firm of experts
to  perform  an  appraisal  to  market  value  of  its  property,  plant  and  equipment  and
recorded the revaluation increment in its statutory BR CL accounting records, without
affecting its tax position, in much the same way as Law No. 8,200/91 later required.
As  the  revaluation  increment  had  eliminated  the  effects  of  the  supplemental  price-
level restatements, no further action was taken and the Company did not apply the
incremental indexation.

Under  US  GAAP,  revaluations  of  assets  to  market  value  are  not  permitted  and  the
effects  of  the  revaluation  have  been  reversed  in  the  reconciliation  to  US  GAAP.
However, in order to preserve the integrity of the historical cost of its assets based
on  the  price-level  restatement  convention  adopted  by  BR  CL,  the  Company  has
recorded  the  supplemental  price-level  restatement  adjustments,  in  accordance  with
Article 2 of Law No. 8,200/91, as an adjusting item in the reconciliation to US GAAP.
The  Company  has  presented  the  balances  of  shareholders'  equity  and  net  income
(loss) under BR CL, adjusted for the  effects  of  the  revaluation  and  the  replacement
of the reversal by the supplemental price-level restatements, and related tax effects,
as a subtotal, prior to presenting the reconciling items to US GAAP. The subtotal also
includes  the  effects  of  including  an  additional  two  years'  inflation  accounting
adjustments through to 1997 for purposes of US GAAP.

Shareholders'  equity  under  US  GAAP  was  increased  by  R$  3,028,301  and  R$
3,149,121 at December 31, 2004 and 2003, respectively, due to the supplementary
inflation  restatement  adjustments  and  reduced  by  R$  2,619,220  and  R$  2,723,720
at  December  31,  2004  and  2003,  respectively,  due  to  the  reversal  of  the
revaluations, before tax effects.

(iii) Inflation indices

The  indexation  of  the financial  statements  through  1995,  except  for  the  year  1990,
under  BR  CL  was  based  on  an  official  government  index,  the  Unidade  Fiscal  de
Referência  -  UFIR  and  for  the  year  ended  December  31,  1990  on  a  consumer  price
index (Índice de Preços ao Consumidor, or IPC). For purposes of US GAAP, a general
price index, the Índice Geral de Preços - Mercado, or IGP-M, was used to record the
additional  inflation  restatement  in  1996  and  1997  and  the  supplementary  inflation
restatement through 1995 (see above).

(Amounts in thousands of Brazilian reais-R$, unless otherwise indicated)

(b) Income taxes and social contribution

Under  BR  CL,  deferred  tax  assets  are  recognized  at  the  estimated  amounts  that
management considers are probable to be recovered. In addition, deferred income taxes
are shown gross rather than net.

Under US GAAP, deferred  taxes  are  recorded on  all  temporary  tax  differences.  Valuation
allowances  are  established  when  it  is  more  likely  than  not  that  deferred  tax  assets,
including tax loss carryforwards, will not be recovered. Deferred tax assets and liabilities
are  classified  as  current  or  long-term  based  on  the  classification  of  the  asset  or  liability
underlying the temporary difference, and are presented net.

For  purposes  of  deferred  tax  accounting,  the  US  GAAP  adjustments  relating  to  inflation
restatement  of  land  and  the  push-down  expenses  from  the  Plan  G0  pension  fund  (j)(ii)
below  and  sabbatical  paid  leave  benefits  are  treated  as  permanent  tax  differences,  as
such items are not deductible for tax purposes by the Company.

Taxes  on  income  in  Brazil  consist  of  two  types  of  taxes:  income  tax  and  social
contribution (Note 10 (a)). In Brazil, the tax law and tax rates are sometimes significantly
altered  by  provisional  measures  ("medidas  provisórias")  announced  by  Presidential
decree.  The  provisional  measures  can  affect  tax  rates  as  well  as  other  areas  that  could
impact deferred taxes. Until September 2001, these measures remained in force for one
month  and  expired  automatically  if  they  were  not  extended  for  an  additional  one-month
period. In September 2001 all provisional measures were automatically enacted, and the
Presidential  decree  powers  restricted.  Under  BR  CL,  when  calculating  deferred  income
taxes, the provisional measures are usually taken into account.

Under  US  GAAP,  only  enacted  tax  rates  may  be  used  to  calculate  deferred  taxes.  Tax
rates  for  future  periods  which  have  been  established  by  provisional  measures  are  not
considered to have been enacted and are ignored. However, the provisional measure, to
the extent it has not lapsed, is used for determining the amount of current  tax  payable.
Deferred  income  tax  adjustments  on  income  arising  from  different  enacted  tax  rates
amounted to R$ 2,319 during 2002.

Shareholders' equity under US GAAP was reduced by R$ 1,325,935 and R$ 1,373,460 at
December 31, 2004 and 2003, respectively, due to deferred tax adjustments on US GAAP
differences, excluding revaluations.

No  valuation  allowance  adjustments  were  required  to  be  included  in  the  reconciliation
between BR CL and US GAAP.

(c) Financial instruments and concentration of credit risk

Under BR CL, there are less detailed requirements regarding the disclosure of information
on financial instruments not reflected on the balance sheet or on concentration of financial
instruments with credit risk.

Under  US  GAAP,  the  applicable  accounting  practice  for  financial  instruments  depends  on
management's intention for their disposition and requires adjustments to their market or
fair values. Additional information on face or contract or notional principal amount; nature

and terms including (i) credit and market risk, (ii) cash requirements and (iii) accounting
policy followed; amount of loss, if any party  to  the  financial instrument  fails  to  perform;
and  policy  as  to  requiring  collateral  is  required.  Disclosure  as  to  concentration  of  credit
risk  arising  from  all  financial  instruments  is  required  to  include  information  about  the
activity, region or other characteristic that identifies the concentration; amount of loss if
parties  to  the  concentrated  risk  fail  to  completely  perform;  and  policy  as  to  requiring
collateral.

Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
Instruments  and  Hedging  Activities"  of  the  U.S.  Financial  Accounting  Standards  Board
(“FASB”)  establishes  accounting  and  reporting  standards  for  derivative  instruments  and
for hedging activities. It requires that an entity recognize all  derivatives  as  either  assets
or  liabilities  and  measure  those  instruments  at  fair  value.  This  statement  was  effective
January  1,  2001  and  did  not  have  a  significant  impact  on  the  Company’s  financial
statements.

No adjustments have been included in the reconciliation from BR CL to US GAAP.

(d) Cash and cash equivalents

Under BR CL, cash equivalents are not defined.

Under  US  GAAP,  SFAS  No.  95,  "Statement  of  Cash  Flows",  defines  cash  equivalents  as
short-term  highly  liquid  investments  that  are  both  (i)  readily  convertible  to  known
amounts  of  cash  and  (ii)  so  near  their  maturity  that  they  present  insignificant  risk  of
changes  in  value  because  of  changes  in  interest  rates.  Generally,  only  investments  with
original  maturities  of  three  months  or  less  qualify  under  that  definition.  No  adjustments
have been included in the reconciliation from BR CL to US GAAP.

(e)  Investments in debt and equity securities

Under  BR  CL,  marketable  debt  and  equity  securities  are  generally  stated  at  the  lower  of
inflation-indexed amortized cost or market value less interest or dividends received. Gains
and losses are reflected in earnings.

Under US GAAP, in accordance with SFAS No. 115, "Accounting for Certain Investments in
Debt  and  Equity  Securities",  the  accounting  and  reporting  for  investments  in  equity
securities  that  have  readily  determinable  fair  values  and  for  all  investments  in  debt
securities is as follows:

(i) Debt  securities  that  the  enterprise  has  the  positive  intent  and  ability  to  hold  to
maturity  are  classified  as  held-to-maturity  securities  and  are  reported  at  amortized
cost.

(ii) Debt  and  equity  securities  that  are  bought  and  held  principally  for  the  purpose  of
selling them in the near term are classified as trading securities and reported at fair
value, with unrealized gains and losses included in earnings.

(iii) Debt  and  equity  securities  not  classified  as  either  held  to  maturity  or  trading
securities  are  classified  as  available  for  sale  securities  and  reported  at  fair  value,
with unrealized gains and losses excluded from earnings and reported in a separate
component of shareholders' equity.

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002
(Amounts in thousands of Brazilian reais-R$, unless otherwise indicated)

For  purposes  of  US  GAAP,  certain  unrealized  gains  and  losses  from  the  Company’s
available-for-sale  securities  are  recorded  directly  in  shareholders'  equity,  net  of  tax
effects, until realized. Shareholders' equity under US GAAP was reduced by R$ 92 and R$
99 at December 31, 2004 and 2003, respectively, for unrealized losses from available-for-
sale securities.

(f) Property, plant and equipment

(i) Revaluations of property, plant and equipment

BR  CL  permits  appraisal  write-ups,  provided  that  certain  formalities  are  complied
with.  The  revaluation  increment  is  credited  to  a  reserve  account  in  shareholders'
equity. Depreciation of the asset revaluation increments is charged to income and an
offsetting portion is relieved from the revaluation reserve in shareholders' equity and
transferred  to  retained  earnings  as  the  related  assets  are  depreciated  or  are
disposed

For  US  GAAP  reconciliation  purposes,  net  revaluation  of  property,  plant  and
equipment in the amounts of R$ 2,619,220 and R$ 2,723,720 at December 31, 2004
and 2003, respectively, have been eliminated in order to present property, plant and
equipment  at  historical  cost,  indexed  for  inflation  through  1997  based  on  a  general
price  index,  less  accumulated  depreciation.  The  depreciation  on  such  revaluation
charged  to  income,  totaling  R$  104,500,  R$  134,245  and  R$ 95,841  for  the  years
ended  December  31,  2004,  2003  and  2002,  respectively,  has  also  been  eliminated
for US GAAP purposes.

Under  BR  CL,  no  deferred  tax  liability  was  recorded  on  the  revaluation  increment.
Under US GAAP, although the depreciation from the additional inflation restatement
((a)(i) above) and the supplementary inflation restatement ((a)(ii) above) will not be
deductible  for  tax  purposes,  these  depreciation  charges  are  considered  to  be
temporary tax differences as the expense will reverse through income in the future,
and, as such, are recorded for purposes of determining deferred tax liabilities.

(ii) Different criteria for capitalizing and depreciating capitalized interest

Under BR CL, until December 31, 1995, capitalization of interest cost incurred during
the  construction  period  as  part  of  the  cost  of  the  related  property,  plant  and
equipment  was  not  required.  However,  as  permitted  by  the  Brazilian  Water  and
Sewage Plan (Plano Nacional de Saneamento Básico - PLANASA), SABESP capitalized
interest  on  construction-in-progress  through  1989.  Also,  under  BR  CL  as  applied  to
companies in the utilities industry, during the period from 1979 to 1985, a notional
interest  rate  was  applied  to  construction-in-progress  computed  at  the  rate  of  12%
per  annum  of  the  balance  of  construction-in-progress;  that  part  which  related  to
interest  on  third-party  loans  was  credited  to  interest  expense  based  on  actual
interest costs with the balance relating to the self-financing portion being credited to
capital  reserves.  Beginning  in  1999,  SABESP  has  capitalized  indexation  charges  on
the  real  -  denominated  loans  and  financing  and  the  foreign  exchange  effects  on
foreign currency loans and financing.

Under  US  GAAP,  in  accordance  with  SFAS  No.  34,  "Capitalization  of  Interest  Cost",
interest  incurred  on  borrowings  is  capitalized  to  the  extent  that  borrowings  do  not
exceed  construction-in-progress.  Such  interest  is  capitalized  as  part  of  the  cost  of
the related assets with a corresponding credit to financial expenses. Under US GAAP,

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002

the  amount  of  interest  capitalized  excludes  the  indexation  charges  associated  with
the  borrowings  and  the  foreign  exchange  gains  and  losses  on  foreign  currency
borrowings.

The  effects  of  these  different  criteria  for  capitalizing  and  amortizing  interest  are
presented below:

(iii) Valuation of long-lived assets

Under  BR  CL,  companies  are  required  to  determine  if  operating  income  is  sufficient
to absorb the depreciation or amortization of long-lived assets, within the context of
the  balance  sheet  as  a  whole,  in  order  to  assess  potential  asset  impairment.  As  it
pertains to property, plant and equipment, in the event that such operating income
is  insufficient  to  recover  the  depreciation  due  to  their  permanent  impairment,  the
assets,  or  groups  of  assets,  are  written-down  to  recoverable  values,  preferably,
based on the projected discounted cash flows of future operations.

Under US GAAP, SFAS No. 144, "Accounting for the Impairment or Disposal of Long-
lived Assets", requires companies to periodically evaluate the carrying value of long-
lived assets to  be  held  and  used,  and  for  long  lived  assets  to  be  disposed  of,  when
events  and  circumstances  require  such  a  review.  The  carrying  value  of  long-lived
assets  is  considered  impaired  when  the  anticipated  undiscounted  cash  flows  from
identified  assets,  representing  the  lowest  level  for  which  identifiable  cash  flows
largely independent of the cash flows of other groups of assets and liabilities, is less
than  their  carrying  value.  In  that  event,  a  loss  is  recognized  to  the  extent  that  the
carrying value exceeds the fair market value of the assets.

No  adjustment  has  been  included  in  the  reconciliation  from  BR  CL  to  US  GAAP  to
take account of differences between the measurement criteria, as based on analysis
of cash flows measured at the smallest unit of assets groups for which cash flow data
is captured no impairment provisions were required. Losses recognized on the write-
off of property, plant and equipment arose primarily from adjustments related to the

(Amounts in thousands of Brazilian reais-R$, unless otherwise indicated)

withdrawal  of  concession  assets,  construction-in-progress  projects  which  were
deemed to be no longer economically feasible and obsolescence write offs.

(g) Deferred charges

Under BR CL deferral of feasibility study costs and pre-operating expenses incurred in the
construction  or  expansion  of  a  new  facility  is  permitted  until  such  time  as  the  facility
begins commercial operations. Deferred charges are amortized over a period of five to ten
years.

Under  US  GAAP,  such  amounts  do  not  meet  the  conditions  established  for  deferral  and
accordingly are charged to income as incurred.

The balance of feasibility study costs outstanding, amounted to R$ 39,097 and R$ 48,951
at  December  31,  2004  and  2003,  respectively,  was  written-off  for  US  GAAP  purposes.
The  net  effects  from  amortization  and  deferrals  in  the  statement  of  operations  at
December  31,  2004  was  an  increase  of  R$  9,854  and  at  December  31,  2003  and  2002
were reductions of R$ 3,894 and R$ 216, respectively.

(h) Dismissal encouragement program

As  discussed  in  Note  13  (b),  in  December  2003  the  Company  announced  a  one-time,
special  dismissal  encouragement  /  early  retirement  program.  Under  BR  CL,  the  total
estimated termination benefits for all employees who would formally accept the offer were
accrued for at December 31, 2003. Under US GAAP, such benefits are considered special
termination benefits, as defined in SFAS No. 88, “Employers' Accounting for Settlements
and  Curtailments  of  Defined  Benefit  Pension  Plans  and  for  Termination  Benefits”  and  as
such, are only allowed to be accrued as an expense when an employee accepts the offer.
At December 31, 2003, approximately 330 employees had requested to apply to enter the
dismissal encouragement program. In the reconciliation between BR CL and US GAAP, the
difference  between  the  estimated  benefits  under  BR  CL  and  the  estimated  benefits
associated  with  those  employees  who  had  accepted  offers  at  December  31,  2003  has
been  reversed  for  US  GAAP.  Such  benefits  were  accrued  and  expensed  in  2004.  At
December 31, 2004, 711 employees entered this program and the Company had paid R$
29,409.

(i) Pension benefits

Under  BR  CL,  prior  to  2002,  amounts  related  to  the  pension  plan  were  recorded  on  an
accrual  basis  as  the  obligations  for  contributions  fell  due.  In  accordance  with  a  new
accounting  standard  issued  by  IBRACON  and  approved  by  the  CVM,  effective  January  1,
2002, Brazilian public companies must account for pension obligations based on actuarial
calculations and provide certain disclosures related to their pension plans. Under the new
standard,  the  actuarial  pension  obligation  determined  at  the  date  of  adoption  could  be
either  recorded  directly  in  shareholders’  equity,  or  prospectively,  during  the  five-year
period  ending  December  31,  2006  in  results  of  operations.  As  permitted,  the  Company
has elected to recognize this transition obligation on a straight-line basis through income
over five years beginning in 2002. The amortization of the liability is being presented as
an “Extraordinary item” in the statements of operations, net of applicable tax effects.

Under  US  GAAP,  the  Company  accounts  for  its  pension  plans  in  accordance  with  the
provisions  of  SFAS  No.  87,  "Employers'  Accounting  for  Pensions,"  which  among  other
requirements, requires that the Company recognize the actuarially-determined liability of

F-66

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002
(Amounts in thousands of Brazilian reais-R$, unless otherwise indicated)

its  pension  plan  obligations.  SFAS  No.  87  also  requires  that  an  additional  liability
(minimum  pension  liability)  is  required  to  be  recorded  when  the  accumulated  benefit
obligation  exceeds  the  fair  value  of  the  plan  assets,  less  accrued  pension  amounts.  This
additional minimum liability is recorded as a charge to accumulated other comprehensive
income in equity.

Although the recently adopted accounting standard under BR CL requires the Company to
recognize  pension  obligation  based  on  actuarial  methods  effective  January  1,  2002,
differences under BR CL related to the prescribed actuarial methods, date of first adoption
and  amortization  of  transition  obligations,  among  others,  as  compared  with  those  under
US GAAP, generate reconciling adjustments for US GAAP purposes.

SFAS  No.  132  (revised  2003),  “Employers'  Disclosures  about  Pensions  and  Other
Postretirement  Benefits”  sets  forth  the  requirements  for  information  that  must  be
disclosed with respect to the Company’s pension plans, which are presented in Note 24.

(i)

Pension plan (Plan G1)

The  Company  sponsors  a  defined-benefit  plan  for  its  employees  (Plan  G1).  For  the
purposes of calculating the funded status of Plan G1, the provisions of SFAS No. 87,
were applied with effect from January 1, 1992, because it was not feasible to apply
them from the effective date specified in the standard.

(ii) Supplementary pension plan (Plan G0)

Pursuant  to  a  law  enacted  by  the  State  Government,  certain  employees  who
provided  service  to  the  Company  prior  to  May  1974  and  retired  as  an  employee  of
the  Company  acquired  a  legal  right  to  receive  supplemental  pension  payments
(which  rights  are  referred  to  as  “Plan  G0”).  The  Company  pays  these  supplemental
benefits  on  behalf  of  the  State  Government  and  makes  claims  for  reimbursement
from the State Government, which are recorded as accounts receivable, shareholder
under BR CL (see Note 6). No expense is recognized for these benefits under BR CL.

Consistent with the guidance in SEC Staff Accounting Bulletin Topic 5-T ("SAB No. 5-
T"),  under  US  GAAP,  the  Company  recognizes  the  costs  and  obligations  associated
with  Plan  G0  supplemental  pension  benefits  incurred  by  the  State  Government  on
behalf of the Company with respect to its employees on a “push-down basis,” as the
Company  is  the  recipient  of  the  benefits  of  the  employee  service  for  which  the
supplemental  pension  benefits  are  made.  These  benefits  are  accounted  for  in
accordance  with  SFAS  No.  87.  Eventual  amounts  received  as  reimbursement  from
the State Government, if any, are treated as additional paid-in-capital.

Retained  earnings  was  reduced  in  the  first  year  of  presentation  (1998)  for  the
actuarial  liability  computed  under  SFAS  No.  87.  and  the  balance  of  amounts  due
from the State Government for pensions paid was charged to income, as this amount
relates to a charge for past services rendered by the Company’s former employees.
Amounts  reimbursed  to  the  Company  by  the  State  Government  were  accounted  for
as additional  paid-in  capital  and  a  reduction  of  the  actuarial liability  to  reflect  gross
benefits  paid.  The  remaining  unpaid  reimbursable  balance  due  from  the  State
Government (effectively a subscription receivable) was charged off as a deduction to
shareholders' equity.

(iii) Sabbatical paid leave

F-67

COMPANHIA DE SANEAMENTO BÁSICO DO ESTADO DE SÃO PAULO - SABESP

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 AND 2002
(Amounts in thousands of Brazilian reais-R$, unless otherwise indicated)

The  Company  also  pays  amounts  equivalent  to  three  months  of  vacation  for  each
five years' of service as a form of sabbatical paid leave to certain of the Company’s
employees for which it also claims reimbursement from the State Government (Note
6).  Consistent  with  the  guidance  in  SAB  Topic  5-T,  under  US  GAAP  the  Company
recognizes  the  costs  and  obligations  associated  with  these  sabbatical  leave  benefits
incurred  by  the  State  Government  on  behalf  of  the  Company  with  respect  to  its
employees on a “push-down basis,” as the Company is the recipient of the benefits
of the employee service for which the supplemental pension benefits are made. The
Company  has  accounted  for  this  sabbatical  expense  by  relieving  directly  against
retained  earnings  for  the  first  year  presented  and  subsequently  the  Company
recognized as a charge to income the receivable due from the State Government, for
sabbatical leave paid, as this amount relates to a charge for past services rendered
by  the  Company’s  former/current  employees.  Amounts  reimbursed  by  the  State
Government, if any, are accounted for as additional paid-in capital.

During  the  year  ended  December  31,  2000,  in  the  financial  statements  prepared  in
accordance  with  BR  CL,  sabbatical  leave  accruals  totaling  R$23,747,  which  had  in
prior  years  been  charged  to  income,  and  were  accounted  for  as  a  receivable
(reimbursement)  due  from  the  State  Government,  were  reversed,  as  the  Company
does not consider this to be an expense under BR CL. Similarly, during December 31,
2004,  2003  and  2002,  total  amounts  not  accrued  were  (R$  14,743),  R$  140  and
459, respectively. Such amounts, consistent with the US GAAP difference mentioned
above, were ‘pushed down’ as expenses in the reconciliation to US GAAP.

(iv) Summary of pension benefits adjustments

different criteria for pension and benefit accounting are presented below:

(j) Segment reporting

Under BR CL, no separate segment reporting is required.

Under US GAAP, SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information"  establishes  the  standards  for  the  manner  in  which  public  enterprises  are
required  to  report  financial  and  descriptive  information  about  their  operating  segments.
SFAS  No.  131  defines  operating  segments  as  components  of  an  enterprise  for  which
separate  financial  information  is  available  and  evaluated  regularly  as  a  means  for
assessing  segment  performance  and  allocating  resources  to  segments.  A  measure  of
profit  or  loss,  total  assets  and  other  related  information  are  required  to  be  disclosed  for
each operating segment.

The  Company  operates  in  two  segments:  water  services  and  sewage  services,  see
Note 26.

(k) Comprehensive income

BR CL does not embody the concept of comprehensive income.

Under  US  GAAP,  the  Company  has  adopted  the  provisions  of  SFAS  No.  130,  "Reporting
Comprehensive Income." A foreign (i.e., non-U.S.) registrant may present the statement
of  comprehensive  income  in  any  format  permitted  by  SFAS  No.  130.  The  information
required  by  SFAS  No.  130,  has  been  included  in  the  condensed  financial  statement
information as prepared in accordance with US GAAP below.

(l) Provision for dividends and interest on shareholders' equity

Under  BR  CL,  at  each  annual  balance  sheet  date  management  is  required  to  propose  a
dividend distribution from earnings and accrue for this in the financial statements. Under
BR  CL,  companies  are  permitted  to  distribute  a  notional  amount  of  interest,  subject  to
certain  limitations,  calculated  based  on  the  government  TJLP  interest  rate,  on
shareholders' equity. Such amounts are deductible for tax purposes and are presented as
a  deduction  from  shareholders'  equity.  Although  not  affecting  net  income  except  for  the
tax  benefit,  in  certain  cases  companies  include  this  notional  charge  in  interest  expense
and  reverse  the  same  amount  before  totaling  net  income.  The  Company  presents  the
financial expense net of the reversal in its financial statements (Note 19).

Under  US  GAAP,  since  proposed  dividends  must  be  ratified  or  modified  at  the  annual
shareholders'  meeting,  dividends  would  generally  not  be  considered  as  declared  at  the
balance  sheet  date  and,  as  such,  would  not  be  accrued.  However,  because  the  State
Government  is  the  Company’s  controlling  shareholder,  the  minimum  dividend  proposal
when made by management at year end is maintained as a provision, and therefore, no
adjustments  has  been  included  in  the  reconciliation  from  BR  CL  to  US  GAAP.  Interim
dividends  paid  or  interest  credited  to  shareholders  as  interest  on  shareholders'  equity
under BR CL is considered as declared for US GAAP purposes. Under US GAAP, no similar
interest distribution concept exists.

Distributions per share data (in the form of dividends or interest on shareholders’equity)
is not required to be disclosed under BR CL.

Interest  on  shareholders'  equity  per  thousand  common  shares  for  the  years  ended
December 31, 2004, 2003 and 2002 were as follows:

(m)  Related parties

Under BR CL, related parties are generally defined in a more limited manner and require
fewer disclosures than US GAAP. The Company has expanded its disclosure for purposes
of BR CL.

No adjustments have been included in the reconciliation from BR CL to US GAAP.

(n) Items posted directly to shareholders' equity accounts

Under  BR  CL,  various  items  are  posted  directly  to  shareholders'  equity  accounts.
Examples include certain capitalized interest, the effects of adjustments to tax rates and
tax  incentive  investment  credits  received.  As  noted  in  (a)  above,  Brazilian  utility
companies  used  to  capitalize  interest  attributable  to  construction-in-progress  at  the  rate
of 12% per annum of the balance of construction-in-progress and that part which relates
to  interest  on  third-party  loans  is  credited  to  interest  expense  based  on  actual  interest
costs  with  the  balance  relating  to  the  self-financed  portion  being  credited  to  capital
reserves.

Under US GAAP, such items relating to third-party debt would be posted to the statement
of  operations.  Since  the  original  posting  to  equity  accounts  would,  under  US  GAAP,  be
made  directly  to  the  statement  of  operations,  these  adjustments  are  included  in  the
reconciliation  of  shareholders'  equity  and  net  income  determined  in  accordance  with  US
GAAP.

(o) Discounting

Under  BR  CL,  discounting  of  trade  receivables  and  payables  to  present  value  is  not
permitted.  Under  US  GAAP,  APB  No.  21  "Interest  on  Receivables  and  Payables",  such
discounting,  in  certain  cases,  is  required  to  record  the  effects  of  implicit  interest  income
or  expense  or  which  are  different  from  market  rates  on  long-term  assets  and  liabilities,
except  for  transactions  in  which  interest  rates  are  affected  by  the  tax  attributes  or  legal
restrictions  prescribed  by  a  government  agency.  No  adjustments  have  been  included  in
the reconciliation from BR CL to US GAAP.

(p) Classification of statement of operations line items

Under  BR  CL,  as  noted  above,  the  classification  of  certain  income  and  expense  items  is
presented differently from US GAAP. The Company has recast its statement of operations
under BR CL to present a condensed statement of operations prepared in accordance with
US GAAP. The reclassifications are summarized as follows:

(i)

Interest  income  and  interest  expense,  together  with  other  financial  charges,  are
displayed  within  operating  income  in  the  statement  of  operations  presented  in
accordance  with  BR  CL.  Such  amounts  have  been  reclassified  to  non-operating

NOTES TO THE FINANCIAL STATEMENTS

(Amounts in thousands of Brazilian reais-R$, unless otherwise indicated)

income  and  expenses  in  the  condensed  statement  of  operations  prepared  in
accordance with US GAAP.

(ii) Under  BR  CL,  gains  and  losses  on  the  disposal  or  impairment  of  permanent  assets
are classified as non-operating income (expense). Under US GAAP, gains and losses
on the disposal or impairment of property, plant and equipment are classified as an
adjustment to operating income.

(iii) As  described  in  Note 12  (b)  and  (j)  above,  following  the  issue  of  a  new  accounting
standard  under  BR  CL,  effective  January  1,  2002,  the  Company  is  amortizing  the
related  transition  obligation  related  to  Plan  G1  over  five  years.  The  related
amortization,  as  permitted,  is  being  presented  as  an  “Extraordinary  item”  net  of
taxes,  in  the  statement  of  operations.  Under  US  GAAP,  this  amortization  expense
would be included as part of operating income.

(q) Earnings per share

Under  BR  CL,  net  income  (loss)  per  share  is  calculated  on  the  number  of  shares
outstanding  at  the  balance  sheet  date.  Information  is  disclosed  per  lot  of  one  thousand
shares,  because  this  is  the  minimum  number  of  shares  of  the  Company  that  can  be
traded on the stock exchanges.

Under US GAAP, in accordance with SFAS No.128, "Earnings per Share", the presentation
of earnings per share is required for public companies, including earnings per share from
continuing  operations  and  net  income  per  share  on  the  face  of  the  statement  of
operations,  and  the  per  share  effect  of  changes  in  accounting  principles,  discontinued
operations and extraordinary items either on the face of the statement of operations or in
a  note.  A  dual  presentation  is  required:  basic  and  diluted.  Computations  of  basic  and
diluted  earnings  per  share  data  are  based  on  the  weighted  average  number  of  shares
outstanding  during  the  period  and  all  potentially  dilutive  shares  outstanding  during  each
period presented, respectively.

The  weighted-average  number  of  shares  used  in  computing  basic  earnings  per  share  for
December  31,  2004,  2003  and  2002  was  28,479,577,827.  The  Company  had  no
potentially dilutive shares outstanding during 2004, 2003 or 2002.

 (r) Financial statement note disclosures

BR  CL  requires,  in  general,  less  information  to  be  disclosed  in  the  notes  to  the  financial
statements  than  US  GAAP.  The  additional  disclosures  required  by  US  GAAP  which  are
relevant to these financial statements are included in this Note 23, 24 and 25.

The date used to determine pension benefits was September 30.

The  amortization  of  the  unrecognized  liability  at  transition  is  over  16  years
commencing on January 1, 1990.

The expected long-term rate of return on plan assets was determined based on the
weighted  average  estimated  return  of  the  plan  assets,  which  includes  equity
securities,  real  state,  loans  and  fixed  income,  based  on  information  obtained  from
SABESPREV. This projected long-term rate includes the projected long-term inflation
rate  and  takes  into  consideration  such  factors  as  projected  future  interest  yield
curves and economic projections available in the market.

The  plan’s  investment  policies  and  strategies  are  aimed  to  reduce  investment  risk
through  diversification,  considering  such  factors  as  the  liquidity  needs  and  funded
status  of  plan  liabilities,  types  and  availability  of  financial  instruments  in  the  local
market,  general  economic  conditions  and  forecasts  as  well  as  requirements  under

strategies  are  determined  with  the  support  of  reports  and  analyses  prepared  by
SABESPREV  and  independent  financial  consultants.  Under  its  current  investment
strategy,  pension  assets  of  the  Company  are  allocated  with  a  goal  to  achieve  the

government securities for internal management, are as follows:

• 

• 

papers securitized by the National Treasury will not be permitted.

exposure to fluctuations in exchange rates will not be permitted, i.e., if there
are any exchange bills in the portfolio, swaps must be used to hedge existing
exposure.

Restrictions with respect to asset portfolio investment, in the case of variable-income
securities for external management, are as follows

• 

• 

• 

• 

day-trade operations will not be permitted.

sale of uncovered options is prohibited.

swap operations without guarantee are prohibited.

leverage will not be permitted, i.e., operations with derivatives representing
leverage  of  asset  or  selling  short  are  prohibited;  such  operations  cannot
result in losses higher than invested amounts.

In November 2004, the FASB issued SFAS No. 151, Inventory Costs an amendment
of  ARB  No.  43,  Chapter  4,  which  amends  Chapter  4  of  ARB  No.  43  that  deals  with
inventory  pricing.    The  Statement  clarifies  the  accounting  for  abnormal  amounts  of
idle  facility  expenses,  freight,  handling  costs,  and  spoilage.    Under  previous
guidance, paragraph 5 of ARB No. 43, chapter 4, items such as idle facility expense,
excessive spoilage, double freight, and rehandling costs might be considered to be so
abnormal,  under  certain  circumstances,  as  to  require  treatment  as  current  period
charges.  This Statement eliminates the criterion of “so abnormal” and requires that
those  the  costs  of  conversion  be  based  on  the  normal  capacity  of  the  production
facilities.    The  provisions  of  this  Statement  shall  be  effective  for  inventory  costs
incurred  during  fiscal  years  beginning  after  items  be  recognized  as  current  period
charges.  Also, this Statement requires that allocation of fixed production overheads
to June 15, 2005.  Earlier application is permitted for inventory costs incurred during
fiscal years beginning after the date this Statement is issued.  The provisions of this
Statement  shall  be  applied  prospectively. 
is  analyzing  the
requirements of this new Statement and believes that its adoption will not have any
significant impact on the Company’s financial position,  results  of  operations  or  cash
flows.

  Management 

In  December  2004,  the  FASB  issued  SFAS  No.  153,  Exchanges  of  Nonmonetary
Assets  an  amendment  of  APB  No.  29.    This  Statement  amends  Opinion  29  to
eliminate the exception for nonmonetary exchanges of similar productive assets and
replaces it with a general exception for exchanges of nonmonetary assets that do not
have  commercial  substance.  The  Statement  specifies  that  a  nonmonetary  exchange
has  commercial  substance  if  the  future  cash  flows  of  the  entity  are  expected  to
change  significantly  as  a  result  of  the  exchange.    This  Statement  is  effective  for

nonmonetary  asset  exchanges  occurring  in  fiscal  periods  beginning  after  June  15,
2005.  Earlier application is permitted for nonmonetary asset exchanges occurring in
fiscal  periods  beginning  after  the  date  this  Statement  is  issued.    Retroactive
application  is  not  permitted.    Management  will  apply  this  Statement  in  the  event
exchanges  of  nonmonetary  assets  occur  in  fiscal  periods  beginning  after  June  15,
2005.

In  September  2004,  the  FASB  issued  FSP  EITF  Issue  03-1-1,  which  delayed  the
effective  date  of  paragraphs  10-20  of  EITF  Issue  No.  03-1,  The  Meaning  of  Other-
Than-Temporary Impairment and Its Application to Certain Investments. Paragraphs
10-20  of  EITF  Issue  No.  03-1  give  guidance  on  how  to  evaluate  and  recognize  an
impairment  loss  that  is  other  that  temporary.    Application  of  these  paragraphs  has
been deferred pending issuance of proposed FSP EITF Issue 03-1a.  Management has
concluded that EITF Issue No. 03-01 is not applicable to its current operations since
it does not have any investments classified as available-for-sale or held-to-maturity,
or other investments carried at cost.

At its March 31, 2004 meeting, the Emerging Issues Task Force (EITF) reached final
consensus on EITF Issue No. 03-6, Participating Securities and the Two-Class Method
under  FASB  Statement  No.  128,  Earnings  per  Share.    Typically,  a  participating
security  is  entitled  to  share  in  a  company’s  earnings,  often  via  a  formula  tied  to
dividends on the company’s common stock.  The issue clarifies what is meant by the
term  participating  security,  as  used  in  Statement  128.  When  an  instrument  is
deemed  to  be  a  participating  security,  it  has  the  potential  to  significantly  reduce
basic  earnings  per  common  share  because  the  two-class  method  must  be  used  to
compute  the  instrument’s  effect  on  earnings  per  share.    The  consensus  also  covers
other  instruments  whose  terms  include  a  participation  feature.    The  consensus  also
addresses  the  allocation  of  losses.    If  undistributed  earnings  must  be  allocated  to
participating securities under the two-class method, losses should also be allocated.
However, EITF 03-6 limits this allocation only to situations when the security has (1)
the  right  to  participate  in  the  earnings  of  the  company,  and  (2)  an  objectively
determinable contractual obligation to share in net losses of the company.

The  consensus  reached  in  EITF  03-6  is  effective  for  fiscal  periods  beginning  after
March  31,  2004  (effectively  the  second  fiscal  quarter  for  calendar  year-end
companies).  EPS in prior periods must be retroactively adjusted in order to comply
with  the  consensus  decisions  reached  in  EITF  03-6.  The  Company  does  not  expect
that this consensus will have any impact on its calculation of Basic and Diluted EPS.
