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

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps are being taken to ensure the enforcement of regular risk assessment and monitoring of private water supplies by local authorities as per their responsibilities outlined in the Private Water Supplies Regulations 2016.

Private water supplies are regulated by local authorities. They are responsible for identifying risks to the quality of the water and must have comprehensive monitoring programmes in place to sample the drinking water for any element, organism or substance that they believe may cause the supply not to be wholesome.

Defra expects all local authorities to undertake their statutory duties. Local authorities are regularly reminded of their duties, and where they may not be being complied with, in the Chief Inspector of Drinking Water’s annual reports on the quality of private water supplies in England. Local authorities’ compliance with reporting duties is raised by officials from Ministry of Housing, Communities and Local Government through their regular liaison meeting with the Local Government Association.
