Here are all the reported sewage overflow totals for PORTLAND HARBOUR CASTLE COVE/PORTLAND HARBOUR SANDSFOOT CASTLE** in 2023.

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.
