Water Supply Byelaws Guide [PDF ebook] 

In February 1985 a Byelaws Guidance Panel{1) was formed by the United Kingdom Water Fittings Byelaws Scheme(2) to produce a Guide to Byelaws the aim being that it should: (a) assist water inspectors, manufacturers, architects, consultants, merchants, installers and consumers to understand byelaws based on the Model; (b) bring about uniformity of approach to byelaw enforcement throughout the UK; (c) be suitable for use as a training document; {d) be subject to continual review by the Panel to ensure its compliance with the latest requirements; (e) comply with byelaw guidance issued by the Department of the Environment; and (f) be based wherever possible on British Standards. 3. This Guide is intended to be applicable throughout the United Kingdom and includes a copy of each byelaw.
