Public Water Supply Models, Data and Operational Management

About this book

Professionals in the water supply industry are faced with a mass of technical information about how best to use new technologies to improve the efficiency of their supply operations. This book will help explain practical problems and potential solutions clearly and comprehensively to readers who may not be familiar with the latest developments in IT and computing. Managers will find it useful in understanding the data requirements of these new systems and it will help them make the most of available resources. It will be of use to those planning and designing new systems and those working with existing ones.
