Anglian Water has 17 CSOs dumping sewage right now

Here are the ones that have been overflowing for the longest, without interruption

We are getting more data collated for each of the CSOs... right now we just have the Constituency. Unfortunately, the water companies use different names for the CSOs in their live data than in the annual returns, so it will take a bit of time to link all the data up....

How many Sewage Overflows are dumping sewage?

We have live data for Anglian Water so we can track what happens every day - given that overflows are supposed to happen on an 'exceptional' basis only - does the chart indicate that?

Total CSOs monitored

CSOs overflowing (30+ mins)

CSOs offline (30+ mins)

There is daily updated information on all constituencies covered by Anglian Water

2024 - By Water Company

How does each water company compare? These are the totals by company for each. The totals are really high, counting things in hours doesn't make it very easy to think about. Here we show how many years of continuous sewage dumps happened in a single year, by water company.

2024 - Asset Spill Duration Comparison

It isn't like there are just a few outliers... the problem exists across the entire estate of water assets. Here we show a 'cumulative frequency diagram' - where the number of CSOs that dumped sewage for a time, or longer, is shown. You can see that many CSOs dumped sewage into a river for months and months.
