About Sewage Map
Find and understand official overflow records. Each location page brings together its map, annual figures, recent reports and sources.
An independent site
sewagemap.org.uk is not a water company or regulator. It is separate from other sites with similar names. We use public data and do not claim to inspect each outlet in person.
Where the information comes from
We use official annual records and water-company reports. Each page names its sources and reporting dates. If a figure is missing, we say so. You can open the original data to check a result.
What you can do
Browse by place, company, river or bathing water. Save useful outlets on your device. For current bathing advice or pollution reports, use the linked official service.

The first release covers England. A monitor report cannot tell you whether water is safe, how much sewage was released, or whether a company broke the law.
