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

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps his Department is taking to reduce sewage discharges into the river Severn.

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) Act. The Act 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.

The Environment Agency (EA) has strengthened its regulation of the water industry by expanding its specialised workforce, increasing compliance checks, and using new data and intelligence tools. The strengthening of the regulatory system has seen a significant increase in the inspections at Severn Trent sewage assets, from 707 in 2024/25 to 1,742 in 2025/26.

All storm overflows are now monitored to ensure that sites are compliant with their permits. For high spilling sites, Severn Trent Water must produce a spill reduction plan as required by the Environment Act 2021. Where the EA identifies non-compliance, it will not hesitate in taking enforcement action.

For Price Review 24, which runs from 2025-2030, Severn Trent Water will be investing £1.7 billion to reduce the use of storm overflows. This investment will reduce storm overflow spills by 26% over the five-year period, a reduction down to an average of 14 spills per overflow.
