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 provide (a) financial, (b) planning and (c) infrastructure support for the (i) development and (ii) improvement of sewage treatment facilities.

Ofwat published their final determinations for Price Review 2024 (the price, investment and service package for water companies in England and Wales) on 19 December, which sets company expenditure and customer bills for 2025-2030.

This will deliver substantial, lasting, improvements for customers and the environment through £104 billion of investment in the water sector, including improving over 1700 wastewater treatment works.

Government recognises the importance of having a robust drainage and wastewater system both now and for future demand. 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.

It is ultimately water companies’ responsibility to maintain and improve their sewage treatment facilities, as needed.
