Pollution Summary 2022

Here are all the reported sewage overflow totals for River Avon in 2022. Sometimes sewage can be being dumped for months at a time.

These numbers are very slightly different from the Rivers page - This is because there is an invalid grid reference on the pollution consent - so we don't know where the CSO is. We're working on it.

Data Sources & Accuracy

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

Experimental derived data from Thames Water API, Some data may be missing or inaccurate. This 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.
