system operations and management services to cities and other companies.

Go with the

Flow

Hello!  It’s  me,  Water.  I’m  the  one  who’s  there  for  you 

whenever  you  need  me,  even  though  you  tend  to  take 

me  for  granted.  No  hard  feelings—I  get  it.  After  all,  I’m  

just two parts hydrogen and one part oxygen. But humor 

me. Let me show you how I travel from the source to your 

tap. If you come along with me on this adventure, you’ll 

be amazed at all the places I go, and all the good things 

that happen when I get there!

I fall from the sky as
 snow or rain.

I don’t even need a parachute–
      woo-hoo!

My

Journey

to the tap

Admit  it:  you  turn  on  your  faucet 
without  giving  it  a  second  thought. 
Do you think the tap water fairy waves 
a  wand  and  I  magically  appear?  Au 
contraire! Depending upon where you 
live,  I  might  travel  hundreds  of  miles 
to  get  to  you.  And  that’s  only  after 
jumping  through  all  kinds  of  water 
quality  hoops.  It’s  quite  a  journey,  let 
me tell you. It all starts with me sitting 
in  a  cloud,  waiting  for  the  adventure 
to begin…

When I land, I either make it to a lake or river, or I seep
           into the ground, where I end up in an aquifer deep
under the Earth’s surface.

4

  If  I trickled through the ground to the       
           aquifer, a groundwater well hauls me up 
as many as 1,000 feet to be treated.

    It’s quite a ride!

If  I’m in a lake or river, 
 I relax for a while until I’m pulled 
out by pumps and taken to a 
water quality treatment plant. 

After I get cleaned up, I have to pass some
    really tough water quality tests. 

     Most people don’t  like taking tests, but
 I love it; it’s  how I know I’m safe to drink.

   P hew! After all that,
I’m sent with some of my 
friends to wait our turn in a
water storage tank.

Not to brag or anything, but I’m kind 
of a big deal. Thanks to me, you can 
wake  up  to  a  nice  hot  shower  and 
a delicious cup of coffee. And that’s 
just  the  beginning;  the  list  goes 
on  and  on.  Your  food?  Yep,  I  grew 
that. Your blue jeans? Me again! The 
tires  on  your  car  and  the  fuel  that 
makes  it  go?  You  got  it—I  helped 
make them. I make everything from 
computer  chips  to  potato  chips. 
And who wants to imagine a world 
without  potato  chips?  The  fact  is,  I 
make  good  things  happen  pretty 
much everywhere I go.

In Gig Harbor, Washington, I clean up the family dog.

      to make golf courses green.

    the candy-making process at See’s—yum!

In Visalia, California Dairies uses
    me to make milk. No cow tipping allowed!

To tell the truth, I couldn’t do the amazing things I do 
without California Water Service Group. It’s not that I’m 
lazy or anything, but if it were left up to me, I’d just kick 
back  wherever  I  landed.  I  certainly  wouldn’t  be  where 
you  need  me,  I  wouldn’t  be  clean,  and  I  wouldn’t  be 
able to make so many good things happen. So I have to 
give credit where credit is due—thanks for everything, 
California Water Service Group!

Here I am being cleaned.

This scientist is getting up close and

              Peninsula.

10

Uh-oh: a leak in the water main! 
   Thanks for the quick repair.

11

Here are some storage tanks
     being constructed–
         how awesome is that?

12

Once my job is done, I’m taken away to
   be cleaned so I can start the process
          all over again.

13

They make

Good  Things
happen
too

It turns out, I’m not the only one who’s a big deal around here. In 2016, 
the  people  at  California  Water  Service  Group  made  good  things 
happen  in  so  many  ways:  they  helped  customers  save  28  billion 
gallons of water. They invested $228.9 million to build and upgrade 
pipes,  pumps,  and  water  quality  treatment  plants.  They  analyzed 
nearly 58,000 water samples and conducted nearly 385,000 water 
quality tests. They answered 600,000 customer service calls. They 
taught elementary-school kids all about me, and even helped some 
high schoolers pay for college. And if all that wasn’t enough, their 
stockholders contributed $665,000 to charitable organizations in 
California, Washington, Hawaii, and New Mexico. Nice!

15

I may not get as 
much attention
as i’d like, but 
California
Water Service 
Group got a lot
of recognition
in 2016.

Maybe next year, I’ll get some
cool awards ,too
       (hint, hint).

Letter to our 
Stockholders

Dear fellow stockholder:

If you thought Water’s adventure from 
the source to the tap was exciting, wait 
until you hear about our journey through 
2016.  It was definitely a year for making 
good things happen—for our customers, 
stockholders, communities, and employees.     

We anticipated it would be a tough year 
financially, given the continuing drought 
in California and the fact that 2016 was 
the third year of a three-year rate case 
cycle for California Water Service (Cal 
Water), our largest subsidiary.  Despite 
these circumstances, we delivered strong 
results.  Net income for the year was $48.7 
million, compared to $45.0 million 
in 2015, and earnings per common 
share were $1.02, up from $0.94 
in 2015.  Total revenues were 
$609.4 million, an increase of 
3.6% compared to the prior year.  
And, in January 2017, our Board 
declared our 289th consecutive 
quarterly dividend and increased 
the annual dividend for the 50th 
consecutive year.  

We invested a record 
$228.9 mil lion
in  water system 
infrastructure
impr ovements!

Even better, we reached two significant 
milestones that support our goal of 
building long-term stockholder value while 
providing high-quality water to customers 
at affordable rates.  First, we invested a 

record $228.9 million in expanding and 
upgrading our water infrastructure.  Second, 
we concluded our 2015 General Rate Case 
in California.   

Enhancing Stockholder 
Value

Let’s begin with our capital investment 
program.  By investing in infrastructure 
projects that provide critical customer 
benefits, such as quality and reliability, we 
also provide value to stockholders, who 
earn a return on this investment.   

In 2016, our investment in infrastructure 
included:  
$83.8 million in new water lines, which increases 
reliability for customers

$4.9 million in water treatment plants and 
treatment plant upgrades, which enables us  
to provide high-quality water 

$34.3 million in wells, tanks, and pumps, which 
ensures that  we can deliver water supplies where 
customers need them 

$13.2 million in information technology projects, 
which is key to providing excellent customer service

One of the many advantages of being served by a regulated utility is 
that all capital investments are reviewed and approved by state utility 
commissions as part of the rate-setting process.  

It was through this process that Cal Water received authorization in 
2016 to begin two of its largest capital projects ever: a $60 million, 
seven-mile, large-diameter pipeline project in Southern California, and 
a $70 million project for water quality treatment at 38 wells to meet an imminent new water 
quality standard for 1,2,3-trichloropropane (TCP).  When the projects are completed,  
Cal Water will be able to request expedited administrative approval to add them to rate base 
and begin earning a return on them. 

That brings us to the second important stockholder value story of 2016: after an extensive, 
18-month review of rates, water system improvement plans, and costs, the California Public 
Utilities Commission (Commission) issued a favorable, on-time decision on Cal Water’s 
General Rate Case. This case was the largest in the company’s 90-year history, and the 
Commission’s approval of rate increases means that we can continue to make water system 
improvements that enable us to deliver a safe, reliable water supply. 

The decision authorizes Cal Water to invest a total of $658.8 million in infrastructure projects 
throughout California in 2016, 2017, and 2018.  Included in the $658.8 million is $197.3 million 
for “advice letter” projects, which are projects that we will complete before we ask to include 
them in rates.  It also increases revenue by an estimated $45.0 million in 2017, up to  
$17.2 million in 2018, up to $16.3 million in 2019, and up to $30.0 million upon completion  
and approval of the advice letter projects.

In a separate approval, the Commission authorized us to begin collecting $2.9 million in 
drought expenses incurred in 2014 and 2015.  We continue to track drought expenses in 2016 
and 2017 for future recovery.  

Finally, the Hawaii Public Utilities Commission approved a $1.1 million increase in revenues to 
recover the costs of several infrastructure improvements in Ka’anapali, including replacement 
of meters and service lines, recoating and reinforcement of a 1.5 million-gallon storage tank, 
two additional new storage tanks, and upgrades to the computer system used to monitor 
and control the water system.    

Here’s the bottom line: maintaining, expanding, and updating water infrastructure requires 
regular investment.  While the nation’s overall water infrastructure gets a dismal D grade 
from the American Society of Civil Engineers, our systems continue to be in far superior 
condition.  And that’s good news for our customers.

Delivering High-Quality Drinking Water and Water for Reuse

As new water quality standards are set and existing standards become increasingly stringent, 
water treatment will continue to make up a large part of our capital investment program.  
In 2015, we installed treatment units at nine well sites to meet a new state standard for 
chromium-6; in 2016, we turned our attention to new challenges.  

As previously mentioned, we began work on water quality treatment that will be required 
to meet a new state standard for TCP, which is expected to become effective in 2017.  
Although the California Public Utilities Commission has approved the TCP treatment for 
future rate recovery, we are hoping to mitigate the impact on customer rates by pursuing a 
lawsuit to recover these expenses and other damages from the companies responsible for 
TCP contamination.   

Lead was also a constituent of concern in 2016, due to the ongoing lead contamination 
crisis in Flint, Michigan.  We are compliant with health and safety codes mandating the 
use of lead-free materials in water systems, and we test our water sources regularly 
to ensure that the water is not corrosive.  (Corrosive water can cause lead from home 
plumbing to leach into the water.)  

So much more to share!

25

Even so, we went a step further in 2016, engaging an expert third party to ensure that our lead and 
copper compliance program was second to none.  We also completed lead and copper monitoring 
as required by the United States Environmental Protection Agency (EPA) and collaborated with 
public health agencies on a plan to conduct additional testing in schools in 2017.

We did all this while continuing our rigorous water 
quality testing and treatment program, analyzing nearly 
58,000 samples and conducting almost 385,000 tests 
for  275 constituents. 

On the water reuse side of the business, our contract with the West Basin Municipal Water 
District (West Basin) was extended to 2021 by a unanimous vote of its Board of Directors.  
Pursuant to the contract, we will continue to maintain and operate the distribution system for 
the Edward C. Little Water Recycling Facility, the largest water recycling facility of its kind in 
the United States.     

We also continued to make significant upgrades to our wastewater treatment plants.  In 
Hawaii, we replaced controls at sewer pump stations to improve wastewater spill prevention.  
In New Mexico, we replaced 3,600 feet of recycled water pipeline and upgraded the Rio 
Communities biological treatment aeration system.  We also purchased 116 acres of land near 
the Rio Del Oro Wastewater Treatment Facility and installed irrigation systems to allow for the 
environmentally friendly spreading of high-quality, treated effluent.

Providing Affordable, Excellent Service

As important as water system improvements and water quality testing are, they tend to go 
unseen by the customer.  What is seen by the customer is our service, and when it comes to 
service, we strive to deliver both affordability and excellence.     

Keeping rates affordable is a challenge for all water providers, because the costs of providing 
water service are rising nationwide.  As we’ve said, water systems need to be maintained and 
updated, and new water quality standards need to be met.  That’s why efficient operations 
and innovative rate-making are key to keeping rates affordable.    

For example, Cal Water proposed in its 2015 General Rate Case to consolidate rates for 
some districts, spreading these costs over greater numbers of customers.  The Commission 
ultimately approved consolidation of rates in seven service areas. Cal Water also sought 
approval to enhance its Low-Income Ratepayer Assistance program, which discounts bills for 
qualified low-income customers, and its Rate Support Fund, which discounts bills in districts 
where the costs of providing water service are highest.  

Despite rising costs, we continue to deliver a clean, reliable water supply right to the 
customer’s tap for less than a penny per gallon in nearly every community we serve.  

In addition to affordable rates, customers expect excellent service.  To make sure that’s what 
they’re getting, we track key performance metrics.  In 2016, we:

Received nearly 50,000 calls per month, and answered 84% of them within 20 seconds

Made an average of 2,100 two-hour appointment windows with customers each month, and arrived on 
time 97.8% of the time

Produced and sent 5.5 million bills, achieving an accuracy rate of 99.2%

We also introduced new, simplified bills and partnered with FranklinCovey© to develop a 
certification program for our customer service supervisors and managers.

27

In May, we 
celebrated our 
customers’ 
tremendous 
conservation 
efforts!

We’re committed to fulfilling our promise to provide customers with quality, service, and 
value, and we were thrilled to be ranked highest in overall customer satisfaction among the 
24 largest water utilities in the western United States in J.D. Power’s inaugural Water Utility 
Residential Customer Satisfaction Study (SM).  The 2016 study measured performance in six 
areas: delivery (including reliability and quality), price, billing and payment, conservation, 
communications, and customer service.  

Even more extraordinary is the fact that we received this honor in the midst of a historic 
drought in California.  We believe it validated our customer-first approach to drought 
response and our efforts to meet ambitious water-use reduction targets set by the State of 
California while maintaining excellent relationships with our customers and communities.  

It started back in April 2015, when the Governor declared a drought emergency and issued 
an Executive Order mandating a 25% reduction in urban water use.  To achieve this target, 
the State Water Resources Control Board (the State Board) established water-use reduction 
requirements based upon communities’ respective residential per-capita water use.  We 
responded by establishing an individual water budget for each customer and setting up a 
system for surcharges, appeals, and water banking.  Then we pulled out all the stops to help 
our customers achieve their targets.  

In May 2016, the State Board did the unexpected: in response to improving drought 
conditions in parts of California, it allowed water providers to eliminate water-use reduction 
requirements if they could prove that they could meet their customers’ water demands for 
three years, assuming the continuation of severe drought conditions.  After assessing our 
water supplies, we eliminated surcharges in all of our California service areas, but continued 
to ask customers to achieve modest water-use reduction targets.  At year-end, our customers 
had achieved total water savings of 23.5% compared to 2013.

That’s where we stood when 2016 came to a close, but the story doesn’t end there.  At the 
same time it changed course on emergency conservation actions, the State Board began 
collaborating with several state agencies on a plan to make conservation a way of life 
in California.  The plan, released in early 2017, includes regulations intended to promote 
efficient water use, eliminate water waste, strengthen local drought resilience, and improve 
agricultural water-use efficiency and drought planning.  We will partner with the State Board 
to implement these regulations between 2017 and 2020.

Building a Strong Reputation

Our leadership during the drought emergency strengthened our brand with customers and 
regulators alike.  After all, crisis response can make or break an organization’s reputation.  

Unfortunately, another opportunity to prove ourselves arose in June, when the catastrophic 
Erskine Fire destroyed 285 homes and charred 48,000 acres in our Kern River Valley service 
area.  Power was knocked out immediately, so we brought people, supplies, and emergency 
generators from other parts of the Company to assist the community and help the local team 
keep water flowing.  In the heartbreaking aftermath, employees distributed stockholder-
funded gift cards so that customers who had lost everything could at least buy essentials.   
In addition to the gift cards, the Company matched employee donations to the local 
Salvation Army for relief efforts.  Local Manager Chris Whitley received the prestigious Living 
Water Award from the National Association of Water Companies for his role in leading the 
Company’s emergency response efforts.    

29

Our charitable giving reflects our purpose: to improve the quality of life for our customers, 
employees, communities, and stockholders.  Some of our corporate contributions are made 
in response to tragedies like the Erskine Fire; others are made to support the day-to-day 
efforts of organizations that share our commitment to improving the quality of life in the 
communities we serve, such as food banks, homeless shelters, and agencies that assist youth, 
seniors, and veterans in need.  We also fund a Company scholarship program that distributes 
$60,000 to students each year; this year’s two grand prizes of $10,000 scholarships went to 
students in Salinas and Rancho Palos Verdes.  Altogether, we made $665,000 in charitable 
contributions in 2016.  

We are proud that our employees share our commitment to giving back.  Throughout 
the Company, our people take the initiative to organize toy drives, clothing drives, and 
blood drives to help those in need.  One Stockton employee even took it upon herself to 
spearhead an effort to raise $10,000 for a local family that lost its father in a tragic home 
accident in 2016.

Employees as Best Advocates

Obviously, our employees care about our customers and communities. And we care about 
them.  So in addition to professional development opportunities, including customer service 
and leadership training, we doubled down on safety training in 2016.  It’s pretty simple; we 
want our employees to be safe and healthy.  We want them to be engaged.  And we want 
them to have the tools they need to serve customers.  Our focus on being an employer of 
choice seems to have paid off; in 2016, we were named a Great Place to Work® by the 

30

Great Place to Work Institute® for the first time ever.  We 
were also named one of the top 100 places to work in the 
greater San Francisco Bay Area by the Bay Area News 
Group for the fifth year in a row.  

In 2016, we welcomed two people to the officer team.  
Elissa Y. Ouyang was promoted to Chief Procurement 
Officer, and Gerald A. Simon was promoted to Chief 
Safety and Emergency Preparedness Officer.  In addition, 
as a reflection of their expanded responsibilities and 
increasingly complex roles, we announced the promotion of Timothy B. Treloar to Vice 
President of Water Quality and Chief Utility Operations Officer and Michael B. Luu to Vice 
President of Customer Service and Chief Information Officer.  

On a bittersweet note, we said goodbye to the extraordinary Linda R. Meier, who retired  
from our Board of Directors after 22 years of service.  Linda brought uncommon insight, 
intellect, and professionalism to her role, and we will miss her dearly.  We wish her the very 
best in her retirement.    

While we’re at it, we’d like to wish you the best in the coming year.  We thank you for your 
continued support and investment in California Water Service Group.

To transfer Stock
A change of ownership of shares (such as when stock is sold or gifted or when owners are deleted from or added to 
stock certificates) requires a transfer of stock. To transfer stock, the owner must complete the assignment on the back 
of the certificate and sign it exactly as his or her name appears on the front. This signature must be guaranteed by an 
eligible guarantor institution (banks, stockbrokers, savings and loan associations, and credit unions with membership in  
approved  signature  medallion  programs)  pursuant  to  SEC  Rule  17Ad -15.  A  notary’s  acknowledgement  is  not 
acceptable.  This  certificate  should  then  be  sent  to  American  Stock  Transfer  &  Trust  Company,  by  registered  or 
certified mail with complete transfer instructions. Alternatively, the Direct Registration System can be utilized, which 
allows electronic share transactions between your broker or dealer and American Stock Transfer & Trust Company.
