The reduction in sewage spills has raised debate about the role of weather versus infrastructure improvements in addressing water pollution.

  • There were 291,492 sewage spills into English rivers, seas, and lakes in 2025.
  • This figure represents a 35% reduction from the record number of spills in 2024.
  • The decrease has been attributed mainly to drier weather, with 2025 seeing the driest spring in over 100 years.
  • Untreated sewage was released on average once every two minutes in 2025.
  • Water companies stated that increased infrastructure investment also contributed to the reduction.

In 2025, water companies in England reported nearly 300,000 sewage spills, a significant decrease from the previous year, citing drier weather and infrastructure investment as contributing factors.

Sewage spills have been a major environmental concern, impacting water quality and public health. The sharp reduction has prompted discussion about the effectiveness of current measures and the influence of weather patterns.

Campaigners and stakeholders are expected to scrutinize whether the reduction can be sustained in wetter years and to push for further improvements in sewage management.
