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.
The Inspectorate:
- provides independent scrutiny of water company activities for companies supplying drinking water to consumers in England and Wales;
- works with other stakeholders for the improvement of drinking water quality and to secure drinking water safety;
- commissions research to build a sound evidence base on drinking water quality;
- publishes data on drinking water quality in England and Wales.
