Background
Thames Water is UK's largest water and wastewater services provider, which serves 14 million customers and supplies 2.6bn litres of drinking water each day, with an annual turnover £1.8bn. The company’s business is closely regulated by a number of regulators including Ofwat (The Water Services Regulation Authority), DMI (Drinking Water Inspectorate) and EA (Environment Agency).
