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 (a) adequacy of improvements to Weybridge sewage works and (b) extent of further work needed to reduce storm overflows from that site.

The Environment Agency (EA) has required Thames Water to improve the Event Duration Monitoring of storm overflows at Weybridge Sewage Treatment works as part of the current Water Industry National Environment Programme (WINEP) 2020-25. The EA has inspected Weybridge Sewage Treatment Works in 2024 and is currently investigating possible permit breaches at the site. The regulators will not let companies get away with illegal activity and where breaches are found, will not hesitate to hold companies to account.

Further improvement schemes are planned as part of the WINEP 2025-2030 including tightening of environmental permit limits for phosphorous.
