Thames Water Discharge Map
Thames Water use event duration monitoring (EDM) to record storm discharge activity. EDM monitors indicate when and where a storm discharge is happening.
This map provides near real-time information about storm overflow activity, as indicated by event duration monitoring (EDM).
You can use the map to see if our EDM monitors indicate:
• That overflows are currently discharging into a watercourse • The date and time of the last recorded discharge
The data received from Thame Water EDM monitors isn’t always accurate, and when shared via the map has only received provisional validation. This data doesn’t confirm discharges, it only indicates them. Thames Water are sharing this data as quickly as possible, so you can make more informed decisions.
