Analysing sewage pollution by the Water Industry

Aberafan was the #12 most polluted bathing area in England & Wales, by duration of sewage overflows, as reported by the water companies
Here are all the reported sewage overflow totals for Aberafan in 2022.
If the locations of the sewage outlets look a bit unusual, it is likely that the reporting of the data from the water company is in error. We rely on their data in order to draw these maps.
Accuracy Warning We use data from the water companies, but we are seeing many anomalies, that make us believe that bathing location information is quite poor. The situation is likely far worse than reported here.
Other CSOs may also be located nearby, however the water companies claim that these do not affect the water quality here.

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.
