Cowes, Gurnard was the #16 most polluted bathing area in England & Wales, by duration of sewage overflows, as reported by the water companies
We managed to raise £150 in 2024. That's not enough to keep the site running. Please consider a one-off or small recurring donation.
Donate NowHere are all the reported sewage overflow totals for Cowes, Gurnard in 2024.
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.
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.
Other CSOs may also be located nearby, however the water companies claim that these do not affect the water quality here.
