Sewage outlets within 3 km

Filter by the latest company report. The map follows the filters. This is a location search, not a list of outlets proven to affect Henleaze Lake, and it does not include every possible source of pollution.

Filters apply to the map and list. Recent stops need a current report and a recorded stop time. They do not show whether water is safe.

Questions about Henleaze Lake

The annual classification is in the highest quality class. The Environment Agency sets the class from water samples taken over several bathing seasons, not from a single visit.
