There were at least 537,632 "sewage spills" into rivers in 2024, lasting an almost unbelievable 4,359,366 hours

An image showing the river network in England and Wales, highlighting those polluted with sewage

Rivers Ranked for 2024

Here are all the rivers in England and Wales that had sewage overflows in 2024. As the list is grouped by company, some rivers may feature more than once, being polluted by different companies along their length.

As there are different rivers with the same name in different parts of the country, it didn't seem sensible to group by river name alone.

The category of "river" is made by the water companies in their "Consent to Discharge with Conditions" - so although there are a number of Seas in this list, that's what they are reporting

Data Sources & Accuracy

EDM (Event Duration Monitoring) data and Consented Discharges to Controlled Waters with Conditions from Environment Agency & Data Map Wales, and Scottish Water

Experimental derived data from Thames Water API, Some data may be missing or inaccurate. Live sewage data from Stream Water API

Uses Environment Agency rainfall data from the real-time data API (Beta) - Rainfall data is delayed by up to two days.

This website is intended to provide an accurate representation of the Environment Agency data. The data is hard to use, and thus some errors may have been made. If you find something that is incorrect, please raise an issue at the GitHub issues page and we'll endeavour to fix it quickly.
