Storm overflow map


As part of our Get River Positive commitment, we've pledged to be as transparent as possible with the data we collect about our water recycling network and the improvements that we're making, especially around storm overflows.


The map below shows where our storm overflow monitors are located and provides near real time information on storm overflow activations. Using data from our event duration monitors, this map is updated every 60 minutes and gives an indication of the latest activation date, time and duration.

You can use the search function at the top to find addresses or zoom in on the map to bring up the locations of the overflows. When you pan around on the map itself, click on the coloured icons to see the information about them.


Find out more about our EDM return data and investment in storm overflows and our other Get River Positive commitments.


The data used in this map started to be collected on 5th April 2024, so if a monitor shows n/a in the history, that is because that monitor has not been triggered from that date. History for monitors that have been triggered since then is displayed in the box that shows when you click on an icon.
