London launches pilot project hiring enforcement officer to tackle domestic sewage misconnections
A City Hall-funded trial in west London aims to help councils penalize property owners whose incorrect plumbing routes household sewage into rivers.
The short version
- A dedicated officer is being recruited in west London to trace plumbing misconnections that discharge household sewage into surface drains and waterways.
- Property owners bear the legal responsibility for correcting illegal drainage, while local councils hold enforcement authority.
- If the trial is effective, the initiative may expand across the capital as part of London's 10-year river restoration plan.
- Four of seven apartment blocks identified in late 2024 across Barnet and Harrow remain unresolved, while three in Ealing have been rectified.
