The amount of water required for agricultural crops and orchards is estimated at (36.109) million/m3 annually, and this is where the most is consumed compared to other uses in the area, The amount of water used by the livestock in the area is (146) million/liter annually, and the total water consumption of chicken fields and poultry birds is (7.16) million/liter annually. The estimated amount of water used in the food industry is (0.014) million m3/year.

The amount of surface and ground water is estimated at (171.698) million/m3 in the study area, and surface water represents (65.45%), while groundwater represents (34.55%), and the amount that is consumed is estimated at (38.762) million/m3 for all uses, and it is clear from the above that there is a surplus of water, said surplus is estimated to be at (132.936) million/m3.
