The Water Regulations Advisory Scheme publishes guidance information relating to the Water Supply (Water Fittings) Regulations 1999 in England and Wales and the Scottish Water Byelaws 2004.

Many of the publications produced by the Scheme are available on this website in electronic PDF format for which you will need a copy of Adobe Acrobat version 4.0 or later. To download a free copy of Adobe Acrobat click the link on the left. The publications are also available in hard copy directly from the Scheme or your local water supplier.

The list of publications includes the Water Regulations Guide which includes the wording of the Regulations and Scottish Byelaws, the DETR Guidance Clauses and Water Industry commentary. The Guide replaces the popular Water Byelaws Guide which related to the previous water byelaws in England, Wales, Scotland and Northern Ireland.

The Water Fittings and Materials Directory contains a list of fittings and materials approved by the Scheme for connection to the water supply in buildings.

The Scheme's Information and Guidance Notes (IGNs) and Approved Installation Methods (AIMs) contain information for those designing and installing water systems.
