Clean water is vital for our health and wellbeing.
In Wales, water companies supply drinking water that is wholesome and safe, in accordance with relevant water quality standards. Water not supplied by water companies - a ‘private’ supply - is also monitored and assessed against drinking water standards to ensure its quality. About 80,000 people in Wales have a private water supply.
The Drinking Water Inspectorate provides independent reassurance that water supplies in England and Wales are safe. This includes checking that water companies supply water that is acceptable to the public.
