This book provides a highly illustrated guide to the design, installation and maintenance of hot and cold water supply systems for domestic buildings. Based on British Standard BS 6700, the new edition takes into account revisions to the standard since the book was first published in 1991. It has also been updated to give guidance on the 1999 Water Supply Regulations and includes revisions to the Building Regulations. Written for designers and installers, this immensely practical book will also be of interest to technical staff of water undertakers, property services managers and students of NVQ and BTech courses. It was specially commissioned by the British Standards Institution and written for BSI by Bob Garrett, formerly of Langley College of Further Education and past President of the National Association of Plumbing Teachers.

This publication describes the processes involved in the design installation and maintenance of modern plumbing systems. It recommends a number of plumbing system design and installation specifications that have demonstrated their validity from years of experience. It also examines the microbiological chemical physical and financial risks associated with plumbing and outlines the major risk management strategies that are used in the plumbing industry and emphasizes the importance of measures to conserve supplies of clean water. This work is dedicated to assisting developing countries in achieving the best possible plumbing levels to ensure the highest health benefits from use of sound plumbing practices. It is aimed at administrators and plumbers working in areas that are served by a mains drinking- water supply or sewerage system or are about to install a mains drinking- water supply or sewerage system. It should be of particular value to those working in countries or areas that are in the early stages of introducing modern plumbing systems. While it draws attention to the problems of drinking- water supply and waste removal in developing countries and outlines some of the strategies currently used it does not systematically cover issues specific to developing countries.
