Our role over private water supplies
We have a duty to assess and periodically monitor the wholesomeness of private water supplies to public buildings, commercial businesses or where the supply serves more than one home.
We also monitor the wholesomeness of private water supplies to dwellings that have their own private water supply if the owner or occupier asks us to.
Where we suspect a private water supply is unwholesome or tests show the water fails to meet quality requirements, we will carry out further investigations.
We charge for providing these services.
We carry out risk assessments to determine whether and under what circumstances unsatisfactory water is likely to be supplied. The risk assessment identifies what improvements might be required. It also helps identify the frequency and type of sampling which should be carried out.
We check and monitor the wholesomeness of water by carrying out sampling in accordance with regulations and the results of our risk assessment. Both bacteriological and chemical parameters are tested to monitor whether the supply complies with standards laid out in regulations.
