United Utilities Water Limited has been fined £900,000 after raw sewage was released along the Fylde Coast for more than 35 hours, affecting beaches and tourist areas from Blackpool to Lytham and Fleetwood.

The company pleaded guilty to five environmental permit offences connected with discharges from three coastal pumping stations between 11 and 22 June 2023. At Preston Magistrates’ Court on 8 September 2026, it was also ordered to pay £62,225 in Environment Agency prosecution costs and a £2,000 victim surcharge, bringing the total financial penalty to £964,225.

Sewage reached seven designated bathing waters

The incident began after the partial collapse of a final effluent pipe at Fleetwood Wastewater Treatment Works. The damage reduced the volume of sewage the works could receive, causing wastewater to back up through the wider network.

Following periods of rainfall, sewage was discharged into the Irish Sea from pumping stations at Manchester Square, Anchorsholme and Chatsworth Avenue. United Utilities’ own modelling showed that the resulting plume touched seven bathing waters and substantially affected bathing-water quality in the hours after the releases.

The permits governing those stations allowed discharges only once flows reaching the Fleetwood treatment works had risen to 2,300 litres per second and when seasonal conditions were satisfied. Environment Agency analysis found that the threshold had not been reached when the spills occurred.

No-bathing advice covered the entire affected coastline

The Environment Agency issued no-bathing advice for all eight designated bathing waters along the affected stretch of coast. Sewage was reported on beaches and in marine recreation facilities, including Fleetwood baths, while sampling by a trained citizen scientist indicated the presence of E. coli.

Public-health concerns also led the Food Standards Agency to close three shellfish beds temporarily. The disruption reached major visitor destinations including Blackpool and St Annes, with communities and coastal businesses affected during the summer tourism period.

Blackpool recorded hundreds of thousands fewer summer visitors than in the previous year, although the source does not attribute that entire reduction solely to the pollution. United Utilities later made a voluntary £250,000 payment to Blackpool Council after reporting about the incident used images of Blackpool Tower during a costly tourism advertising campaign.

Five permit breaches led to the court penalty

The Environment Agency classified the pollution as a Category 1 incident, a classification accepted by United Utilities. The company admitted the permit breaches when interviewed under caution in November 2024 and entered guilty pleas at a court hearing on 22 April 2026.

For sentencing, the agency argued that the conduct amounted to reckless culpability and Harm Category 1. United Utilities, treated as a very large organisation with annual turnover of approximately £2.6 billion, was sentenced at Preston Magistrates’ Court nearly three years after the discharges.

Andy Brown, the Environment Agency’s Water Regulation Manager, described the incident as unacceptable and said the penalty reflected both the seriousness of the offences and the harm caused. He said water companies had a fundamental duty to manage their assets and comply with permits protecting seas, rivers and communities.

Repairs and safeguards followed the pipe collapse

United Utilities built a two-kilometre temporary bypass around the damaged pipe, installed extra pumping equipment and used tankers to move wastewater to other treatment works. The Fleetwood site returned to full service after the pipe was repaired.

The company estimated that responding to and repairing the original incident cost about £38 million. It has since carried out further work intended to improve the resilience of the wastewater network along the Fylde Coast, while the Environment Agency has said it will continue investigating permit breaches and pursuing companies that fail to meet their environmental obligations.
