Public Register of Drinking Water Supplies
Our Public Register of Drinking Water Supplies includes some of the information registered drinking water suppliers give us about their supplies. You can search and find the drinking water supplies in your local area in the public register.
Some drinking water supplies may not yet appear on the public register. We're still confirming details of almost 2,000 supplies transferred to us from the Ministry of Health.
