In July 1999, the Water Supply (Water Fittings Regulations) 1999 replaced local water byelaws in England and Wales.
They were made under section 74 of the Water Industry Act 1991 to prevent the waste, misuse, undue consumption, erroneous measurement or contamination of drinking water and set requirements for the design, installation and maintenance of plumbing systems and water fittings. The Regulations are enforceable by each water company as regards their own area of supply.
Water systems and fittings in premises that are, or will be, connected to the public water supply system must comply with the Regulations. If you are planning to carry out plumbing work for any of the following purposes, you must obtain our prior consent:
Welsh Water has produced a Notification Form and explanatory information for your use.
The Water Regulations Advisory Scheme (WRAS) has published a Water Regulations Guide which explains in more detail the requirements of the Regulations.
Please note that statutory requirements relating to drainage are provided for in the Building Act 1984 and associated Building Regulations.
