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 his Department has made of the resilience of the water supply in the long term in Plymouth.

The Government and the Environment Agency work with water companies and other stakeholders to monitor and manage water resources in England. Water companies are responsible for ensuring a secure water supply for their customers. Plymouth lies in South West Water's Roadford Water Resource Zone, which is supplied from reservoirs, rivers, and some boreholes.

Every 5 years water companies must prepare and maintain a water resources management plan (WRMP). The WRMP sets out how a company intends to achieve a secure supply of water for customers, resilient to droughts, and with environmental protections and enhancements over the next 25 years. WRMP's are closely assessed by Ofwat and the Environment Agency, who advise on the acceptability of plans before companies are given permission to publish by the government.

South West Water's latest draft WRMP, which includes the measures it will take to ensure the resilience of water supply in the Roadford zone, was scrutinised by regulators and given permission for publication in January 2025, subject to some revisions, which the company is currently making.
