UK water firms' illegal dry-weather sewage discharges surge in 2026

Suspected illegal raw sewage discharges by UK water companies during dry weather rose sharply in the first five months of 2026, with 7,280 incidents recorded. This indicates systemic permit breaches and heightened environmental pollution, intensifying regulatory and public scrutiny on the sector. The trend suggests ongoing infrastructure underinvestment and potential for stricter enforcement or penalties.
