• Sommario/riassunto: Supply of sufficient clean drinking water is often taken for granted, but it requires a considerable technical and financial effort to ensure reliable and economic water supply. This volume presents an up-to-date overview of water supply management and aims at efficient management of water supply schemes rather than design of new works. Various chapters of the book are devoted to water demands, management of reservoirs and conjunctive use of alternative sources. Asset management and loss control are also considered. Water quality and provision of water to developing communities are also discussed. Water supply management is of concern to developed urban environments as well as developing communities. The book will be equally valuable to the practising water engineer and the newcomer or graduate student in the subject.
