Public Water Supply

Scottish Water provides your water

In Scotland, the public water supply is provided by Scottish Water. Supplies are taken from a number of sources and all need to be treated before they are of sufficient quality to be used by consumers. The extent and type of treatment required depends on the nature of the supply, its quality and any potential risks to quality that are present.

Scottish Water undertakes about 350,000 tests every year on samples of water taken at water treatment works, storage points and consumers’ homes to verify that the water quality meets these standards. DWQR checks the results of these tests and makes sure that any failures are thoroughly investigated.

The information in this Public Supply section allows you to see how many of the tests carried out by Scottish Water met the required standard at a national level and in your local water supply. It contains answers to many of the questions that you may have about drinking water, describes how to contact DWQR, and how we can help.
