نهر الزرقاء
Indirect reuse of reclaimed water from Greater Amman. The reclaimed water (treated wastewater) from the largest wastewater treatment plant in Jordan, As-Samra, flows through the Zarqa River into the King-Talal-Reservoir where it mixes with freshwater. From there it flows into the King-Abdullah-Canal in the Jordan Valley where it further mixes with freshwater. The diluted reclaimed water is reused on about 4,000 farms covering 10,000 hectares in the Southern part of the valley, mostly using drip irrigation.
