Download PDF Water Loss Control by Julian Thornton dkk


The second edition of Water Loss Control has been written in the same spirit as the first edition, as a comprehensive guide to water auditing and hands-on reduction of water and revenue losses in water utility operations and management. The goal of the authors was to update the book with information on important innovations and technologies that have been developed since the first edition was released in July 2002. Climate issues, growing populations and deteriorating water supply infrastructure are exerting unprecedented pressure on water resources throughout the world. As a result, government and regulatory bodies and water utilities are experiencing a growing awareness of the importance of accurately assessing and efficiently controlling water losses as a means to preserve water resources while facilitating growing communities. Hence raising awareness of the extent of the problem and current practices in many systems in North America and around the world is still a very important component of this book. The book covers the tools required to perform an IWA/AWWA standardized water audit both on paper and in the field. Every water utility has unique characteristics and losses and a variety of effective tools must be available in the practitioner’s tool kit. This book provides valuable information for water utility managers to select the correct tools and methodology for the water and revenue losses encountered in their operations. The emphasis of the book is to promote the use of effective water loss control methods and tools as a cost-efficient means of controlling unchecked losses in water utilities. The book is suitable either as an educational tool for the inexperienced operator or as a reference manual for the more experienced operator.

A number of useful water loss publications are available to the water supply industry, however, this publication integrates ideas, techniques, methodologies and references from many international sources, making it a truly flexible and very comprehensive guide, which can be used in a variety of field situations.
