The purpose of this book is to give stakeholders a point of reference and some tools with which they can move forward. In this way, it is hoped that the mistakes of the last 20 years will not be repeated. It should not be necessary for a new generation of water professionals to learn everything all over again. Instead, they should be able to take what has been learned up to now and move on. To help facilitate this process, this book was designed to create greater understanding and awareness of the issues and possible solutions among all stakeholders in the sector.
