Water supply testing

In light of the current limiting Covid-19 circumstances, it is not possible for Flintshire County Council to undertake any visits for the testing of private water supplies until further notice. If you are a householder, (owner occupied or privately rented) , commercial premises or food business and you have concerns about your private water supply drinking water, please e mail Flintshire County Council at for advice. Also consider boiling your water prior to drinking, teeth brushing and using for food preparation or purchase bottled water in the interim until the issue is resolved.

If there is treatment in place on your private water supply, It is recommended that in the absence of any monitoring, consumers and other relevant persons of private water supplies should bolster operational checks and ensure that maintenance is being carried out as required (e.g. replacing UV lamps, regularly changing filters or monitoring chlorine dose) and that you have sufficient spares of essential equipment to ensure supplies remain wholesome at all times.

Also, without putting yourself at risk, if you can safely access your water source, it is wise to check that the source is adequately protected and secure from contamination from flooding overland, pooling of water around the head of the chamber and secure from animal access.

Commercial premises and landlords for privately rented properties should document any actions taken, and if required, present these to the Local Authority to confirm that the supply did not present a risk to health during these exceptional circumstances.

Flintshire County Council will be in contact with all its private water supplies programmed for visits in 2020 in due course, when normal service is resumed.


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

Public Protection 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.

More information about keeping your supply safe and treating your supply you can also visit the Drinking Water Inspectorate’s (DWI) website (new window)
