Polluted by sewage 45 minutes , potential overflows 327 hours in 2026 so far..
Currently not overflowing
Due to inconsistencies in the data from the water company, sometimes the link to the river might not work, sorry
Please consider a one-off or small recurring donation. We need your help to keep this site going.
Donate NowHere 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.
