Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, if he will hold discussions with Thames Water on the adequacy of the time it takes to stop sewage overflows.

My officials and I have regular conversations with Thames Water and other water companies to discuss a range of activities, including the reduction of sewage discharges. I am also meeting with the boards of all water companies, including Thames Water, to set out the government’s expectation of improved performance across all metrics.

Cleaning up England’s rivers, lakes and seas is a priority for the government. The government has taken immediate and substantial action to address the performance of water companies who are not delivering for the environment or their customers.

That is why we are placing water companies under special measures through the Water (Special Measures) Act. This will drive meaningful improvements in the performance and culture of the water industry as a first important step in enabling wider, transformative change across the water sector.

Furthermore, as part of Ofwat’s Price Review 2024 settlement, Thames Water will undertake a significant investment programme to improve the environment over the 2025-30 period. These investments include: £784 million to reduce the use of storm overflows and £1.2 billion to prevent nutrient pollution. Ofwat expects the reduction of the use of storm overflows by at least 29% by 2029-30, down to an average of 14.2 spills per overflow.
