Water quality in England and Wales is regulated by the Drinking Water Inspectorate (DWI). It makes sure all water companies supply safe drinking water that meets legal standards.
At Independent Water Networks Ltd (IWNL) we regularly monitor water quality on all our networks. This involves sampling water in homes and businesses throughout the year, which we share with the DWI.
The DWI produces detailed reports, sharing every water company’s sample results and the conclusions of any audits or assessments. These reports, and other information on drinking-water quality, are available on the DWI’s website.
