Drinking water
United Utilities supplies all mains
water in the north west and they are
required to ensure that it meets
strict quality standards set by the
government.
United Utilities is required to test supplies regularly against national standards and give us the results. There is also a national body called the Drinking Water Inspectorate (DWI).
The DWI is responsible for assessing the quality of drinking water in England and Wales, taking enforcement action if standards are not being met, and appropriate action when water is unfit for human consumption.
