context_page_description: United Utilities Group plc, the United Kingdom's largest listed water company, was founded in 1995 as a result of the merger of North West Water and NORWEB. The group manages the regulated water and waste water network in North West England, which includes Cumbria, Greater Manchester, Lancashire, Merseyside, most of Cheshire and a small area of Derbyshire, which have a combined population of more than seven million.
  The United Utilities Group was the electricity distribution network operator for the North West until 2010, when its electricity subsidiary was sold to Electricity North West. United Utilities' headquarters are in Warrington and the company has more than 5,000 direct employees. Its shares are listed on the London Stock Exchange and the FTSE 100 Index.
  North West England is the wettest region in England, and water hardness across the region is soft to very soft.
context_section_description: United Utilities currently supplies water to a population of 7.3 million people across the North West. United Utilities owned 166 water supply reservoirs, various river and stream intakes, as well as lake abstractions and numerous groundwater sources, to  supply the region. Some reservoirs operated by the company are outside the North West such as the Longdendale Chain in Derbyshire, which were constructed by the Manchester Corporation in the 19th century, and remain networked to the North West's water supply.
  The company also manages 78,000 kilometres of wastewater pipes which take sewage from 7.3 million people for treatment at nearly 600 wastewater treatment works. It also operates 37 renewable energy facilities.
