To ask the Secretary of State for Environment, Food and Rural Affairs, how his Department plans to ensure that sewage treatment facilities (a) in Horley and (b) nationally are upgraded according to agreed timescales.

For Price Review 2024 (PR24), which runs from 2025 – 2030, water companies will be delivering record levels of investment: £104 billion over the next five years.

Ofwat, Environment Agency (EA) and Natural Resources Wales have developed a new Delivery Monitoring Framework for the delivery period from 2025-30. It will establish a system for tracking and reporting on water company delivery of their WINEP obligations, to report to their customers and regulators on progress. Thames Water will be expected to comply with the 6 monthly reporting requirements.

As part of the Environment Act 2021, water companies in England are required to produce Drainage and Wastewater Management Plans (DWMPs). DWMPs set out how a water company intends to improve their drainage and wastewater systems over the next 25 years. These plans will help sewerage companies to fully assess the capacity of the drainage and wastewater network and develop collaborative solutions to current problems and future issues.
