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.

New website for customers to see how their water companies are performing.
Customers can now quickly and easily see how their water company is performing and compare it to other companies. The information can be found on www.discoverwater.co.uk and has a comprehensive range of data covering water quality, public health, customer service and environmental aspects of water and sewerage services. Discover Water is a collaborative project. Led and funded by water companies, it has been delivered by an independent third party and overseen by a sector-wide group, including the sector’s regulators and consumer watchdog. The information used on Discover Water is already separately published by water companies, Ofwat, Defra, Drinking Water Inspectorate, Environment Agency and the Consumer Council for Water.
