Local authorities are required to provide certain information relating to private water supplies to the Secretary of State and Welsh Ministers (in practice the DWI). 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.
The information required to be submitted by local authorities is set out in the following three Annexes as follows;
Annex 1 (XLS 440KB) - An Excel file containing local authority data
This is a blank excel file, which contains the following four worksheets that should be completed with data on all private water supplies in the local authority area, as follows:
i) [Contacts Worksheet] – All local authorities should provide relevant contact details, including where: (a); a local authority does not have any private water supplies; (b); a local authority only has private distribution systems and there is no other information available on these supplies at the time of making the data submission
ii) [Details Worksheet] - Details of each private supply including private distribution systems (where the details are known). The full details of single domestic dwellings should be included, whether or not samples or risk assessments have been carried out.
