Track storm overflow discharge activity, nearby monitored sites, bathing-water proximity and annual company performance in one clearer view.
Event Duration Monitors indicate discharge activity. They do not prove pollution levels or provide real-time swimming safety advice.

Bathing waters
The map layer can show designated bathing waters alongside overflow events, helping users see where monitor activity sits in relation to beaches and official bathing-water classifications.
The storm-releases dashboard presents live or recent overflow activity, bathing-water context and water-company summaries where feeds are available. It is designed to make public environmental data easier to inspect, not to replace official bathing-water warnings or environmental enforcement records.
Storm overflows are designed to reduce sewer flooding during heavy rainfall by releasing excess flow into rivers or coastal waters. An event indicates that a monitored overflow has reported activity, but it does not by itself describe the exact pollution level at a bathing site.
Different water companies publish data using different systems and update schedules. A missing or inactive point can mean no recent event, delayed data, a feed issue or a site outside the currently monitored set.
Overflow activity can be relevant to swimmers and coastal communities, but bathing-water safety also depends on tides, rainfall, currents, bacteria testing and local warnings. Official advice should take priority for health and safety decisions.
