Whether it's for a tranquil walk or an exhilarating windsurf, our 20 beautiful reservoirs are places where people love to go to relax and enjoy the outdoors.
They are - of course - the main source of our drinking water, with 90% of our raw water coming from reservoirs and rivers, and we manage them carefully to ensure the water going into our treatment works is good, clean raw water.
