Water supply and demand modeling for the Jeddah-Makkah-Taif Area, Saudi Arabia : a present and future water balance

الملخص EN

The paper discusses the present and future (1985-2010) water demands and the water resources of the Jeddah-Makkah-Taif (JMT) area in the Western Region of Saudi Arabia.

Also given are data on water distribu- tion, sewerage systems and capacities of treatment plants.

Both the availa- ble and the projected amounts of wastewater for reuse are estimated.

With these data, water demands are matched against available water resources to show the present water status in a tabular display format of a water balance model.

In addition, this paper addresses the impending water crisis if water demand and supply are not brought into balance.
