A private water supply is any water supply which is not provided by a water company (water undertaker) and which is not be considered to be a "mains" supply. Private water supplies can be obtained from a variety of sources including:

  • springs;
  • wells;
  • boreholes;
  • rivers and streams; and
  • lakes or ponds.

All private water supplies can pose a potential threat to health unless they are properly protected and treated.  Unlike mains water supplies, many private supplies are not treated to remove contamination. You may not be able to tell whether your water is safe as contamination may not show as smell, taste or colour of the water. 

Our role

Under section 77 of the Water Industry Act 1991 (28.2MB) we have a duty to check the quality of all water supplies within our area.

The Private Water Supplies Regulations 2009 (102KB) are concerned with the wholesomeness of water obtained from private supplies and require us to sample and analyse the water from these supplies.

For further information, please see the guidance (30KB) and charges (177KB).
