Wastewater reuse is among the main alternatives to overcome water scarcity challenges and to meet the current water needs

The rate of wastewater treatment is still low in many MENA countries, and reuse faces many challenges like; preference for freshwater over wastewater, inadequate information on the status of reuse and disposal of wastewater, and incomplete economic analysis of the wastewater treatment and reuse options

There are many benefits of wastewater reuse. The environmental benefits include reducing the pollution of water resources and sensitive receiving bodies, and controlling saline water intrusion through groundwater recharge. Wastewater reuse also presents economic value by providing significant additional amounts of water and contributing to the conservation of freshwater resources. Additionally, it provides nutrient-rich water for irrigation and reduces the need for chemical fertilizers.
