Wastewater reuse as means to optimize the use of water resources in the West Bank

The increase in demand for the limited raw water resources in the Palestinian Territories has led to the proposals for use of treated wastewater as one alternative for alleviating water shortages and for optimizing the use of water resources. Wastewater reuse is a multi-discipline and important element of water resources development. Wastewater usage releases high quality water for drinking and other purposes. Quantitative, economic, and social aspects related to wastewater reuse in the West Bank are discussed. Through analyses of the estimated cost and expected water quantities, the paper investigates the economic feasibility of wastewater reuse. Social acceptance is elicited by means of questionnaires, which have been applied to farmers and inhabitants in different areas of the West Bank. Wastewater reuse can compensate for about 10 percent of irrigated agriculture, which contributes 35 percent of the total value of the Palestinian agricultural sector The paper presents an analysis of the main aspects of wastewater reuse and defines an approach to the beneficial use of wastewater as a component that should be considered in the strategy for the overall management of water resources in the Palestinian Territories.
