EVALUATION AND REDESIGN OF THE EXISTING WATER DISTRIBUTION SYSTEM IN AL-HILLA PROVINCE

The objective of this work is to simulate distribution network and to enhance the efficiency of existing water distribution system of Al-Hilla province, and to reach an optimal solutions and assumptions in order to improve the hydraulic performance, and to increase the efficiencies of the water supply networks. The hydraulic analysis of the network is based on continuity at nodes and Hazen-Williams formula for head loss calculations by using EPANET2 software program under various scenarios. The data for the water pipe network, such as the maps, diameters, material, utilities, land ordinates, and the area supply method were obtained from Babylon Water supply Directorate. After representation of the existing distribution system by drawing each district network in EPANET2 model and simulation the boundary parameters. The EPAENT2 model was simulated the case study area to analysis the present water distribution network, and then a design improvement was carried out on the existing network. As a result, hydraulically balanced water distribution network (WDN) for the targeted area in Al-Hilla province was accomplished. Thus, positive results of the hydraulics state of parameters around the network were successfully determined.
