Raw Sewage in our Rivers

Sewage is discharged into rivers across the UK and Ireland on a daily basis. This isn’t an isolated problem; it occurs up and down the country, affecting urban city centre rivers and pristine chalk streams alike.

We want to help you find out where sewage is discharged into rivers, enabling you to make informed decisions about where you swim, paddle, catch and play. Our map below shows where the sewerage network discharges and overflows into rivers. Be warned: you might not like what you discover!

Is there sewage in your local river?

At The Rivers Trust, we believe that people should be able to swim, paddle, catch and play without worrying about sewage pollution. That’s why we launched Together for Rivers: an ambitious campaign which hopes to see designated bathing waters introduced to well-used rivers in the UK.

Our hopes of bathing water status in rivers aren’t all that outlandish, either; campaigners at Ilkley have succeeded in securing bathing water status for their local river – a first in England. With enough support, we believe more and more rivers could be given bathing water status, helping to improve rivers for people and wildlife.

Until cleaner rivers become a reality, we will continue to fight for public access to data on sewage pollution. That’s why we created our Sewage Map, which gives details on the location and spill duration of CSOs across England and Wales.

What does the public think?

We asked over 1000 people how they use rivers recreationally and how this might change if rivers were cleaner. Dive into the data and read our Sewage Report to learn more.
