dc.description.abstractWater Supply Distribution Systems Utilities are designed to deliver safe, reliable, affordable, and continuous supplying and distribution of potable water to end users throughout 24 hours. As time elapsed, meeting these commitments embraces multiple challenges in urban areas. The objectives of this work are to evaluate the hydraulic performance of water supply distribution system by assessing the situation of existing water supply distribution system. Also, it was mainly emphasized to estimate the physical water loss in the system to improve the efficacies of the water distribution systems networks to suggest some remedial measures. Water GEMS software was used as a tool to model water distribution system. The model can be used to identify the high pressure and low pressure in the junctions and magnitude of velocity and head loss through pipes were used as base to evaluate the hydraulic performance. Modeling results showed violation of maximum and minimum pressure and low velocity requirements. High pressures in the system occurred both during low demand and peak demand have to be identified and remedial measures is established using pressure reducing valves. It is also proposed to install air release valves at high elevation and sluice valves at low elevations. Modifications in operation and design will improve the current situation of the case study water supply distribution system.en_US
