Water company fined record £900k after coastline sewage spill
United Utilities Water Limited was fined £964,225 for sewage spills into the Irish Sea, impacting bathing waters and tourism along the Fylde Coast.
United Utilities Water Limited was fined £964,225 at Preston Magistrates’ Court on 8 September 2026 after pleading guilty to five environmental permit offences. The company admitted breaches linked to a major sewage spill between 11 and 22 June 2023, which discharged raw sewage into the Irish Sea from three coastal pumping stations. The incident affected eight designated bathing waters, with ‘no bathing’ advice issued by the Environment Agency due to contamination risks. Popular tourist destinations like Blackpool and St Annes suffered significant impacts, with summer visitor numbers in Blackpool alone falling by hundreds of thousands compared to the previous year.
An Environment Agency investigation found the spill began after a partial collapse of a final effluent pipe at Fleetwood Wastewater Treatment Works, reducing sewage capacity and causing backups. Subsequent heavy rainfall led to discharges from pumping stations at Manchester Square, Anchorsholme, and Chatsworth Avenue, violating permit conditions. United Utilities’ own modelling showed a sewage plume affected seven bathing waters, while citizen science sampling detected E. coli. The Food Standards Agency temporarily closed three shellfish beds due to public health concerns.
The company admitted the breaches during interviews and pleaded guilty in court on 22 April 2026. The Environment Agency emphasized the unacceptable nature of the pollution, which harmed residents and businesses along the Fylde Coast. The fine reflects the seriousness of the offences and the harm caused, with water companies held accountable for failing to meet environmental obligations. The regulator pledged continued rigorous oversight of the water industry to address breaches.
In response, United Utilities constructed a two-kilometre temporary bypass, installed additional pumping equipment, and repaired the damaged pipe at Fleetwood Wastewater Treatment Works. The company incurred around £38 million in costs to address the incident and improve wastewater network resilience. United Utilities also made a £250,000 voluntary payment to Blackpool Council after media reports linked images of the iconic tower to the pollution incident, which harmed the area’s tourism image.
