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

To ask the Secretary of State for Environment, Food and Rural Affairs, what recent assessment her Department has made of trends in the level of (a) private investment and (b) Government funding for (i) storm overflows, (ii) wastewater treatment and (iii) other water infrastructure.

Ofwat’s final determinations for Price Review 2024 set company expenditure for 2025–2030. This will deliver substantial and enduring improvements for customers and the environment through a £104 billion upgrade for the water sector. The £104 billion funding package is the highest level of investment in the water sector since privatisation and is set to be the second largest private sector investment programme in this parliament.

Water companies are investing over £11 billion in PR24, a record amount, to improve nearly 3,000 storm overflows across England and Wales over the next five years. Furthermore, £4.795 billion will be spent over the same period to reduce phosphorus pollution from treated wastewater. This represents an increase when compared to the 2022-2023 equivalent prices for Price Review 19, where overall spending was £61bn, storm overflow investment was £3.6 billion, and wastewater treatment improvements were £3.1 billion.
