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

To ask the Secretary of State for Environment, Food and Rural Affairs, whether the £104 billion investment in water and sewage infrastructure announced in July 2025 is aligned with figures proposed in water companies’ most recent Drainage and Wastewater Management Plans.

All English and Welsh water and sewerage companies published their final Drainage and Wastewater Management Plans (DWMPs), which informed the 2024 periodic review.

These DWMPs were produced on a voluntary basis to industry-led guidance. The current cycle of DWMPs, which is now statutory, is supported by new Government guidance [Guidelines for Statutory Drainage and Wastewater Management Plans (DWMPs) - GOV.UK]. This cycle of DWMPs will inform the next periodic review and related water company infrastructure investment.
