|I have studied potable and non-potable reuse as well as impacts of droughts. Following are some of my publications:

|I would like to join a project on potable reuse or on wastewater.
Water resources are essential for every development activity, not only in terms of available quantity but also in terms of quality. Economic and population growth as well as urbanisation are increasing the number of users and uses of water, making water resources scarcer and more polluted. Water scarcity, due to physical lack or pollution, has become one of the most pressing issues globally, a matter of human, economic and environmental insecurity, and extended droughts threaten to worsen these effects in many areas.
Wastewater, whose value had not been appreciated until recently, is increasingly recognised as a potential ‘new’ source of clean water for potable and non-potable uses, resulting in social, environmental and economic beneﬁts. The project will focus on the potential of recycled wastewater (also known as reused water) to become a signiﬁcant source of safe water for drinking purposes and improved sanitation in support of the Sustainable Development Goals. It will also consider human and environmental health, and the views of the public.
Potable reuse is about to become part of national policies in the United States and it has been used, both directly and indirectly, in cities in U.S.; Perth, Australia; Windhoek, Namibia; Beaufort West, South Africa; Singapore; Wulpen, Belgium; Essex, UK. The potential for Europe is enormous and should be studied as a coping strategy.|
