Nablus City, is considered as one of the most important cities in the West Bank either in economical or industrial fields or because of its large population.
The city of Nablus has a total population of 182,615 capita which means that it has a large water demand thus, there is a real need for many water resources and it becomes a priority to maintain the existing resources and try to find new resources.
In order to solve these issues many projects and studies were performed, the master plan we try to summarize is expected to provide a detailed description of the water system then try to propose solutions for many problems that face the municipality such as the dilemma of water losses in the water distribution network which reach in some areas to about 50% and in average it’s about 38% , another dilemma is the intermittent water supply to the consumers that in some cases takes three days or more to provide consumers with water, thus we will try at the end of this study to propose solutions to solve these problems and to give solutions to bridge the gap between demand and supply.
Loss detection used in the existing network depends on taking readings from meters at the outlet of reservoirs and compare it with the summation of meter readings at consumption points, this causes misreading of losses which not allowing NM to discover the main causes of losses and try to fix it. Interventions will be made to increase level of accuracy and details will be made in this project.
This master plan aims to provide a strategic water plan for fifteen years starting from 2012 until the year of 2027 by proposing projects - which are assumed to be implemented as packages - to increase the ability of the distribution network and cover the demand caused by the annual increase in population.
According to the proposed methodology, first data collection from Nablus Municipality that had been collected which contains AutoCAD and GIS data files, field visits were made trying to diagnose, describe and achieve a better understanding of the current situation. Then we made an assumption -according to the existing water situation- to divide Nablus city into six pressure zones which are North Western (NW), North Eastern (NE), Sothern (S), Western (W), Eastern (E) and Central (C), these zones are also divided into thirty distribution areas only twenty seven are activated and there are not activated. These zones are fed from ten reservoirs which distributed in the Nablus area and the reservoirs are fed from water resources which include six ground water wells and five springs.
