In water-scarce areas of the Middle East, greywater (household wastewater excluding toilet waste) is commonly used by poor communities to irrigate home gardens. This both supplements the water available to the household and improves food security. This book draws together material presented at a conference in Jordan in 2007, and examines the technical approaches to treating and using greywater for irrigation, including its associated risks to health and the environment. It discusses many of the non-technical issues that influence effectiveness and sustainability of greywater use. It also takes a hard look at economic issues, arguing that more clarity and consistency from policymakers is essential if low-income, water stressed communities are to make better and safer use of their existing water supplies. The book concludes by offering suggestions for where donor efforts and research could best be focused in the near future.
Greywater use in the Middle East is important reading for researchers, donors, implementing agencies, and policymakers, in the fields of water supply, water reuse, livelihoods and agriculture.
"This new comprehensive reference provides a compelling argument for the use of greywater in the Middle East providing the varied expertise and experience required for its safe and practical use in a single, concise document; this is clearly a positive step forward."

"Greywater use may not solve the water crisis, but this book sheds light and important research on its potential to contribute something to the solution."
