Water Supply (Water Fittings) Regulations 1999
The Water Supply (Water Fittings) Regulations 1999 make provisions for preventing contamination and waste of water supplied by a water undertaker. A water undertaker is a company that has statutory powers and duties to supply water and/or sewerage services to premises within a geographic area designated under the Water Industry Act 1991. These are the incumbent water companies and inset appointees.
Commonly referred to as the Water Fittings Regulations, these regulations were passed with the intention of stopping the waste, misuse, undue consumption and erroneous measurement of the drinking water supply. They do not apply to premises that do not have a public water supply connection.
The Water Fitting Regulations define requirements for the design, installation and maintenance of plumbing systems, water fittings and water using appliances in England and Wales. In Scotland, the equivalent provisions are covered in The Water Fittings Regulations (or Byelaws 2000).
