Polluted by sewage 1,109 hours in 2026 so far..

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 belive that the CSO
started overflowing much later than it did.
Note also that when the CSO 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.
