Thames Water provides drinking water to eight million people and sewage services to 13 million people.

Our supply area covers 5000 square miles across London and the Thames Valley: from Kent in the east to Gloucestershire in the west.

We look after 20,000 miles of water mains and 40,000 miles of sewers – enough pipes to run around the world more than twice.
