Welcome to DWI

The Drinking Water Inspectorate (DWI) was formed in 1990 to provide independent reassurance that water supplies in England and Wales are safe and drinking water quality is acceptable to consumers.

Public supplies in flooded areas

During the current period of flooding Water Companies are maintaining regular checks on the quality of drinking water as is normal. Public Water Supplies are supplied by pipes underground and are not susceptible to flooding. The water company will inform you if there is any need to take action with regard to your water supply. If you do notice a change in your drinking water supply please report it to your water company.

Private supplies in flooded areas

If you have, or are responsible for, a private water supply and you have concerns about the quality of drinking water as a result of the supply being flooded then please contact your local authority Environmental Health Department for advice.
