Water Firms Hide Over 100 Sewage Dumps
6 Jun
Summary
- Over 100 emergency sewage dumps went unreported in 2025.
- Anglian Water led offenders with 23 unreported spills.
- Most overflow pipes lack monitoring, obscuring spill volumes.
Water companies in England failed to report more than 100 instances of emergency sewage dumping in 2025. A total of 126 out of 1,455 releases were not self-reported, with one incident remaining unclear.
Dumping sewage from emergency pipes is illegal unless there's a critical failure. Companies must notify the Environment Agency of releases likely to cause significant pollution. Anglian Water had the highest number of unreported incidents, with 23 failures.
Further data reveals that fewer than 10 percent of England's 7,000 emergency overflow pipes are monitored. Just 686 have event duration monitors, meaning the volume of sewage discharged from most is unknown.
Water UK stated that 91 percent of incidents were reported, and pledged tripling investment to halve spills, upgrade wastewater works, and install more monitors.
