Events for 58a0eeaf05 in 2025

Here you can see the data reported by the Water Industry 'API' - It's not very 'clean'! One particular trick that you can see is where the 'Start' date is regularly incremented, which means that unless you keep an eye on the entire history, which we do, you could be lead to believe that the overflow started much later than it did.
Note also that when the overflow is reported to 'Stop', often the start and end dates of the previous event doesn't line up with the data. This does vary in reliability between water company.

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

Annual figures up to and including 2025 come from official water company returns. The 2026 figure is our own estimate, derived continuously from the companies' live data feeds.

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.
