Summary
Sewage spills in England dropped by nearly half in 2025, mainly due to less rainfall rather than significant infrastructure improvements. The Environment Agency reported a total of 1.9 million hours of sewage spills in 2025, compared to 3.6 million hours the previous year. While drier weather contributed to fewer spills, ongoing infrastructure investments aim to further reduce pollution levels.
