About South West Water
South West Water supplies drinking water and treats wastewater for households and businesses in South West England. Its work covers treatment, the supply network, sewerage, wastewater treatment and the return of treated water to rivers and the sea, along with water meters and priority services.
Households receive their water and wastewater services directly from the company. Businesses can choose a water and wastewater retailer instead, and developers and home-improvement projects can request new water and sewerage connections through Developer Services, which connects around 8,000 new properties each year.
The company is headquartered in Exeter and was founded in 1989. It reports a £2.5bn investment programme by 2030 covering storm overflow reduction, bathing water quality and water resilience.
Product: Regulated drinking water supply and wastewater collection and treatment, with water meters, priority services and new-connection services for developers.
