Water Reuse: An International Survey of current practice, issues and needs examines water reuse practices around the world from different perspectives. The objective is to show how differentlywastewater reuse is conceived and practised around the world as well as to present the varied needs and possibilities for reusing wastewater.
In the first section water reuse practices around the worldare described for regions having common water availability, reuse needs and social aspects. The second section refers to the “stakeholders” point of view.

The third section deals with emerging and controversial topics.Ethical and economical dilemmas in the field are presented as a subject not frequently addressed in this field. The role of governments in respect of public policy in reuse is discussed as well as thedifferent international criteria and standards for reusing wastewater. The importance of public acceptance and the way to properly handle it is also considered.
The fourth section of the book presentscontrasting case studies; typical situations in the developed world (Japan and Germany) are compared to those in developing countries (Pakistan and Brazil) for agricultural and industrial reuse.Indirect planned reuse for human consumption (Germany) is compared with an unplanned one (Mexico). The Windhoek, Namibia case study is presented to emphasize why if the direct reuse of wastewater for humanconsumption has been performed with success for more than 35 years it is still the only example of this type around the world. To illustrate the difficulties of having a common framework for...
