We operate and maintain 100 water treatment works, 30 raw water reservoirs, 288 pumping stations and 235 clean water service reservoirs
We carry out over 400,000 tests per year to ensure our drinking water meets stringent UK and European standards.
On the wastewater side of our business, we have 350 sewage treatment works, including our site in Beckton, East London, which is the largest in the UK.
Several of these works create renewable energy, making us the biggest generator of 'green power' within the M25.
