Abstract
Egypt is facing severe water scarcity combined with the enormous challenges of population growth and increasing food demand. Fortunately, wastewater increases with the population, and the properly treated nutrient rich treated wastewater is a valuable irrigation resource. Sanitation projects often focus on large urban areas, and rural regions do not have access to these services. The low coverage, combined with inefficient treatment results in surface/ subsurface water pollution and related health problems. Onsite treatment of wastewater requires simple, reliable, low energy consuming and low-cost technology. A new holistic approach is needed for ensuring extra irrigation water resources and better public health safety and economic viability.
