Who We Are

We can trace our origins back to the mid-19th century when Victorian engineers began to supply water directly to people’s homes.

Today, we are a water-only company supplying 160 million litres of clean water each day to 707,000 people in east Surrey and parts of West Sussex, west Kent and south London. Our supply area covers 322 square miles, much of it rural.

We are owned jointly by Japanese businesses, Sumitomo Corporation and Osaka Gas. To find out more about our history, supply area and more, visit seswater.co.uk.
