What information do you have about my tap water quality?

We can supply a report about tap water quality in your area for free; we’ll call you back to arrange this. Please complete the details in our Arrange a free call back section on this page.

The report (called a Schedule 4) provides a summary of all of the sample results taken in a supply zone during the most recent calendar year. Supply zones are areas of up to 100,000 people.

We take samples at our treatment works and at customers’ taps and test them for chemical and microbiological parameters.

All of the parameters have either minimum or maximum standards associated with them, which incorporate a large safety margin in order to protect public health.

Some additional standards called ‘Indicator Parameters’ are set to monitor water treatment and distribution processes. Any sample result which fails to meet with a standard is investigated, assessed and prompt remedial action is taken to prevent it happening again. This assessment is reported to the Drinking Water Inspectorate, which sets the standards for drinking water quality.
