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

To ask the Secretary of State for Environment, Food and Rural Affairs, how her Department plans to enforce compliance with proposed stormwater management measures in Buckinghamshire.

The Environment Agency (EA) is responsible for ensuring compliance. The EA has strengthened regulation of the water industry through new dedicated regulation and enforcement teams. Its Thames and East Anglia Areas have completed over 2,400 inspections since April 2025.

The EA has visited 7 Anglian Water assets since April and has followed up on the two minor non-compliances identified. It is planning to visit a further 13 Anglian Water assets in the Buckingham and Brackley area before the end of March 2026.

Stewkley Sewage Treatment Works (STW) and Quainton Sewage Pumping Station, both operated by Thames Water Utilities Limited, were inspected in May 2025 and January 2026, respectively. No major compliance issues were identified, and the operator agreed actions to resolve minor non-compliances found.

Stewkley STW is a high-spilling storm overflow site: measures are in place to investigate and reduce spill frequency under the Water Industry National Environment Programme (PR24) during AMP8 (2025-2030).
