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

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment he has made of the potential implications for his policies of environmental contamination caused by sewage discharges by water companies in Surrey Heath constituency.

For too long, water companies have discharged unacceptable levels of sewage into our rivers, lakes and seas.

That is why we are placing water companies under special measures through the Water (Special Measures) Bill. The Bill 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.

For Price Review 2024 (PR24), which runs from 2025 – 2030, Thames Water will invest £784 million to reduce the use of storm overflows including in and around the Surrey Heath constituency. Additional improvement actions also include increasing treatment capacity at sewage works, providing storage for high flows, reducing flows entering the system and provision of treatment for storm overflows which are separate from the main treatment route.

There have been significant pollution incidents at Camberley and Chobham Sewage Treatment Works in the last few years and these are still subject to Environment Agency investigations. We will not let companies get away with illegal activity and where breaches are found, the EA will not hesitate to hold companies to account. The Environment Agency has also undertaken recent inspections of Sewage Treatment Works, including at Camberley, Lightwater and Chobham.
