Affinity Water supply over 1.8mn homes across the South East, which is a big responsibility and we take it very seriously.

What we’re doing

Not only do we have a responsibility to serve our 3.5mn customers, we also want to make sure we do this sustainably to protect our unique local environment and all the wildlife we share it with.

So, in the five years to March 2020, we beat the water industry’s leakage reduction target of 15%. We’ve also been working on a number of environmental improvement plans to protect habitats for local wildlife, such as the River Misbourne at Amersham programme, and we’ve completely stopped abstraction (i.e. removing water) from the River Chess in the Chilterns Valley, which helps protect this area of outstanding natural beauty.

A flood of activity

There’s no meandering here – we’re on a mission to Save Our Streams and we need your help.
