United Utilities is a British utility company that provides water and wastewater services to approximately seven million individuals in the North West of England. The company has a significant responsibility to manage the catchment land that surrounds its reservoirs to ensure the water it collects and stores is of high quality. United Utilities then treats and delivers this water to its customers, supplying around 1.5 billion litres each day. The company also collects wastewater from customers and surface water from roads and highways, treating it at its wastewater treatment facilities before returning it safely to the environment.
