Severn Trent escapes fine in UK wastewater probe as reduces spills

(Alliance News) - Severn Trent PLC will face no financial penalty, despite "serious failings in its duties to deal effectively with wastewater and sewage", the company and the UK's water industry regulator said on Wednesday.

Coventry, England-based utility Severn Trent is the owner of Severn Trent Water. Ofwat, the water regulator for England and Wales, said it has concluded the wastewater investigation it launched in 2021 without imposing a financial penalty on Severn Trent Water, citing the company's proactive response to storm overflows and investment to fix the issue.

Ofwat found Severn Trent breached its statutory obligations to provide effective drainage and manage sewage, failing to maintain adequate systems and processes, but it said the company had proactively identified the issues before the regulator opened its enforcement case in July 2024. Ofwat noted Severn Trent had already invested GBP98 million to address the problems and accepted a legally enforceable package of undertakings to ensure future compliance.

Severn Trent on Wednesday said it accepts the breaches identified and noted that Ofwat recognised its proactive investment in wastewater assets, board oversight and operational controls.

The company said it committed in 2023 to invest GBP450 million by 2030 through its spills reduction programme to upgrade storm overflows and storage capacity, targeting fewer than 14 average spills per overflow annually by the end of the decade.

"Our investment programme in spills reduction continues across our region at pace with the strength of our whole organisation and supply chain behind it," said James Jesic, group chief executive. "We still have work to do and remain absolutely focused on delivering further improvements for our customers and the environment.''

Average storm overflow spills by the company fell by 41% on year in 2025, and Ofwat said Severn Trent Water has consistently performed better than other wastewater companies. "Severn Trent Water has taken ownership of the problem, has been proactive in identifying and addressing issues with its wastewater assets and ambitious in its approach, with visible benefits already being in place," the regulator said.

Ofwat noted that Severn Trent was the eighth case in its sector-wide probe into UK wastewater and sewage, which has secured enforcement packages and fines of more than GBP300 million. It said two more cases remain open.

Severn Trent shares were down 1.3% to 2,958.00 pence early Wednesday in London. They are up 12% over the past 12 months.
