Water Company Fined £300,000 Following Sewage Spill That Devastated Somerset River Wildlife

Wessex Water has been fined £300,000 after a backed-up sewer discharged sewage into a tributary of the River Yeo in Somerset, causing significant environmental damage in September 2022. The incident, confirmed by the Environment Agency (EA), resulted in the death of dozens of fish, including bullhead and three-spined sticklebacks.

The pollution occurred when a surging manhole overflowed due to a blocked sewer north of Milborne Port, releasing untreated sewage into the water. Subsequent EA investigations revealed elevated levels of harmful substances such as ammonia and chloride in the affected river.

In response, Wessex Water has implemented robust measures to prevent future incidents. These include lining parts of the foul sewer network and installing advanced monitoring equipment to detect potential issues early. Additionally, the company will pay £6,668 to cover the EA’s investigation and enforcement costs.

The penalty funds will be allocated to the Yeovil Rivers Community Trust to support crucial habitat restoration projects aimed at protecting and enhancing local biodiversity. Key efforts will focus on the restoration of wetlands, reedbeds, and ponds at Yeovil Country Park and Long Preston Brook, habitats vital to endangered species such as the water vole.

Once numbering between 600 and 700 in the Yeovil area, water vole populations have declined sharply to an estimated 300-400, largely due to habitat loss from agriculture, urban development, and climate change.

Steven Federico, Environmental Crime Officer at the Environment Agency, emphasized the importance of water voles in maintaining healthy wetland ecosystems. Lorne Thomson, Chair of the Yeovil Rivers Community Trust, highlighted how the funding will support their Water Vole Habitat Enhancement Program, aiming to improve river, pond, and land habitats through the creation of bunds and reedbeds that benefit a wide array of flora and fauna.
