Sewage maps and bathing water quality
Check official bathing-water advice before entering the water. A sewage map shows discharge reports. It does not give a swimming-safety result.
What to do
Open the official bathing-water profile before entering the water. Check local signs and conditions. A nearby or stopped overflow report is not a swimming-safety result.
Check the official bathing-water service
For designated bathing waters in England, use the official service to check water quality and pollution information. Read signs at the site and current local advice. The date and place of the evidence matter.
Stopped does not mean safe
A report that an overflow has stopped does not establish the current condition of the water. Other pollution sources may also be present. Missing or offline monitoring is a gap in evidence, not a clean-water result.
Nearby does not mean connected
An outlet close to a beach or river can discharge into another watercourse. Straight-line distance does not show where pollution travels. Sewage Map keeps location information separate from any verified link in the source.
Use more than one piece of evidence
Check the official advice, local conditions and access information. Follow the Swim Healthy guidance on reducing risks in open water. This site does not issue health advice or approve places for swimming.
