A. The Private Water Supplies Regulations set requirements for private sources of water. With the exception of Northern Ireland, Local Authorities are responsible for checking the safety and sufficiency of private water supplies in their area - normally by the Environmental Health departments. In Northern Ireland this is the responsibility of the Drinking Water Inspectorate at the Department of the Environment.

The Water Supply (Water Fittings) Regulations and Scottish Water Byelaws only apply to properties where the water is provided from the public supply – this includes properties with a private water supply which have a mains water backup supply. These regulations and byelaws do provide a useful code of practice for installation and backflow prevention requirements for private water supplies.
