Water Supply: Standards

Asked by Martin WrigleyLiberal DemocratDepartment for Environment, Food and Rural AffairsTabled Answered 22 October 2025UIN 82812

The question

To ask the Secretary of State for Environment, Food and Rural Affairs, if she will bring forward legislative proposals to require private water supplies to be registered with a local authority who can (a) test them and (b) risk assess them.

Answered by Emma Hardy

Local authorities need only risk assess and monitor private water supplies that they are aware of that are large, shared, or where the water supply is used as part of a commercial or public activity. Supplies to single domestic dwellings need only be risk assessed and monitored if the owner or occupier of the dwelling requests it, and they may monitor at their discretion.
