Water supply testing

Flintshire County Council has in excess of 120 properties whose only source of drinking water is from a private supply.  Monitoring of public and private water supplies takes place to ensure that drinking water in the County poses no risk to health. 

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

  • Wells
  • Boreholes
  • Springs
  • Rivers and Streams
  • Lakes or Ponds

The Environmental Control Section monitors the quality of all private supplies in Flintshire and keeps a register of these supplies. If there are only a small number of people using the supply you may only require monitoring to be done once every 5 years. To find out whether your private water supply is registered, please contact us.

All private water supplies can pose a threat to health unless they are properly protected and treated. 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. Unlike public supplies, many private supplies are not treated to remove contamination.
