SES Water Information

We are a water-only company, supplying drinking water to more than 750,000 customers in East Surrey, West Kent, South London and parts of West Sussex. 85% of our water supply comes from the deep aquifers in the chalk of the North Downs or the large deposits of greensand south of the Downs. We also source 15% of our water supply from the River Eden and it’s stored in our Bough Beech Reservoir, near Sevenoaks in Kent. Water is an essential, and increasingly precious, resource. We understand its value and are committed to sharing this knowledge with our customers – helping to preserve the environment and secure future supplies. But actions speak louder than words, and we will only achieve our goals by working hard and in partnership with the community we are privileged to serve. Please call 01737 772000 in an emergency.
