The service of providing quality potable with enough amounts to Palestinian houses in Nablus city is the responsibility of Nablus’ Municipality (NM). Put in mind that Nablus is a special case as a result of its topology. With the increasing demand for potable water as a result of increasing population growth and urban expansion in the city and the shortages of potable water resources and yearly rainfalls, NM has been encountering a set of serious challenges in securing and distributing enough water to satisfy this increasing demand. More specifically, these challenges are becoming more difficult to address due to the increasing and uncontrollable losses of water in the supply and distribution of water network in Nablus, besides, the deficiencies in forecasting the future supply, demand and loss of drinking water in NM. Thus, developing a reliable forecasting system for water supply, demand and analysis and management of its losses is an inevitable need the NM should work on. To this end, this project aims at developing forecasting models for future prediction of water supplies, demands and losses in Nablus for the purpose of securing enough quality drinking water quantities taking into account the rapid increase in demand, decrease in supply and uncontrollable water losses in the city. Historical data on actual supply amount, actual water consumption (demand) and actual water losses will be used for building such forecasting models. Other factors, like population growth, urban expansion, water supply network distribution and management, rainfalls, cost, water harvesting will be taken into consideration in developing these forecasting models. In addition to providing a model for waste analysis and management to contribute to solving the waste problem in the future. Ultimately, such models would serve in achieving the three pillars of sustainability (economic, environmental social) in the provision of drinking water service in the city which in turn enhances the role of NM in serving its customers (citizens).
