Thames Water is the UK’s largest water and wastewater services company. Our mission is to provide the essential service that’s at the heart of daily life, health and enjoyment. Each day we take millions of litres of water from the environment to provide drinking water to our customers, and then return treated wastewater to rivers and streams. We aim to do this in the most sustainable and responsible way.

For 9 million customers across London and the Thames Valley, Thames Water operates 100 water treatment works, 30 raw water reservoirs and 235 clean water service reservoirs to supply high quality drinking. Furthermore, we operate 67000 miles of sewers and 350 sewerage works to remove and treat more than 4 billion litres of sewage for 15 million customers.

Thames Water is a partner in Smart Water 4 Europe.
