Section 77 of the Water Industry Act 1991 requires a local authority to keep itself informed about the wholesomeness and sufficiency of every private water supply within its area. Each local authority achieves this by conducting its statutory duties which includes; risk assessments, investigations, authorisations and monitoring (sampling and analysis). The Regulations also make provisions for local authorities to charge fees to the relevant person(s) for conducting these duties.
If through these duties a local authority deems a private water supply to be unwholesome and/or insufficient then it has the power under the Regulations to serve notices on the supply in order to mitigate against these risks
Local authorities are under a statutory duty to provide reporting information relating to private water supplies to the Secretary of State and Welsh Ministers. This submission of data is due on 31 January of every year, for records relating to supplies in their area during the previous calendar year.
Given the varying nature and condition of private water supplies available the Inspectorate has made available a number of different Case Studies in order to provide additional guidance for local authorities.
