 Water from the reservoir is diverted through a diversion weir at Addassiyah downstream of the Al-Wehda dam to the King Abdullah Canal where it is mixed with other freshwater sources.Some of the water from the canal is then pumped to Amman to be used as drinking water, after being treated in the Zai water treatment plant.The discharge of effluents from adjacent agricultural lands has caused algae growth and eutrophication especially in spring.
