Statistical Domestic Water Demand Model for the West Bank

The water balance in the West Bank shows a severe deficit. Scenarios and strategies are formulated in order to overcome the deficit problem. These include options for better management of the existing water resources and the enhancement of new resources. This paper focuses on demand modeling as one of the key issues for effective water management. Although past literature about demand modeling is comparatively rich for different regions in the world, this research provides a unique study, due to the past political situation in the Middle East, for water demand modeling in the West Bank. The developed statistical domestic water demand model will assess the factors which influence domestic water use, and determine the parameters that may help in demand management. Rammallah City is used as a case study to illustrate the proposed framework of the analysis. The developed model indicates that water utility authorities can use price as a tool to ration water or encourage reduced water consumption in households.
