Hydraulic Design For a Pumping Station Combined With Conveying Pipeline System Using Computer Models (Beit Jala case study)

Abstract

Beit Jala city like the other Palestinian cities, which are suffering from water scarcity due to conditions of water supply, which is limited, the study aims to design a system for on demand supply for Beit Jala region, which is adequately, satisfy the water requirements for a combination of domestic, commercial, public and firefighting purposes at the right time. Individual pipelines may contain any of several kinds of pumps at one end; they may deliver water to or from storage tanks, In a water pipeline system, system flow control or active devices (gate valves, Air Valves pressure reducing or pressure sustaining valves…etc.) is an integrated part of its operation, for instance, the opening and closing of valves, and starting and stopping of pumps. When these operations are performed very quickly, they can cause hydraulic transient phenomena. To protect the physical integrity of a pipeline system, there is a need to install surge control devices, such as surge relief valves, surge tanks, or air-vacuum valves, at various points in the system. To achieve our goals several models will be chosen and used such as WATER CAD and HAMMER CAD.
