Water Quality

In Northern Ireland, drinking water is either provided through a public supply or via a private water supply. Northern Ireland Water is the public supplier and provides water to over 99% of the of the population in Northern Ireland with the remainder being served by private water supplies such as wells, bore holes or springs.

 

Registration and Monitoring of Private Water Supplies

If you have a private water supply which is shared with other householders or used in the course of a business e.g. renting holiday accommodation or using water for food production, you must register your supply with the Drinking Water Inspectorate under the Private Water Supplies Regulations.  You will complete a registration form and your supply will be placed on a monitoring programme to check that it meets the water quality standards in the Regulations and a Risk Assessment of your supply will also be carried out.

 

The location of private water supplies across Northern Ireland which have been registered with the Drinking Water Inspectorate under the Regulations are available via a Spatial NI web based app.
