We've now updated our Sewage Map to include data from 2022 for England and Wales.
Data published by Defra and Dŵr Cymru/Welsh Water last week shows that untreated sewage was discharged 384,568 times across England and Wales, for a total duration of more than two million hours.
With our map, you can see how where these spills occurred. You can zoom in on your local area, search by location, or visit the 'investigate' tab to see data breakdowns by constituency, receiving water body, and more.
That's not all, though. Soon we will add some new features to the map to help understand the problem of sewage pollution even more. We'll be adding annual summary data from Scotland for 2018-2022. We'll also be sharing near real-time alerts of sewage spills where that data is available, so make sure you sign up to our newsletter to hear as soon as these features go live.
Raw sewage in our rivers
Sewage is discharged into rivers across the UK and Ireland on a daily basis. This isn’t an isolated problem; it occurs up and down the country, affecting urban city centre rivers and pristine chalk streams alike.
