Background: The pressure of consumption spots in eater supply systems is one of the most important hydraulic parameters can be used in optimized management of water distribution networks. Since the pressure has some different effects on various parameters of the network management including its hydraulic functions, reliability, stability and leakage, its control is of great importance in different management levels. Performing the plan for two water supply systems, this paper aimed to analyze and compare the pressure, leakage and quality of water in different spots of the network.Methods: For modeling the network, the software of Water Gems v3/0 was used. It designed and modeled the current network in forms of gravity distribution and direct pumping.Findings: at the minimum time of consumption, the pressure in 45 percent of junctions of the gravity distribution network is more than 70 meters; while in the direct pumping, except two junctions, it is not more than 60 meters. At the maximum time of consumption, pressure in 15 percent of junctions of the gravity distribution network and 35 percent of the direct pumping is less than 30 meters. The rate of water leakage in gravity distribution network at the minimum time of consumption is 43 percent more than that of direct pumping network. The rate of remained CL in 62 percent of pipes of direct pumping network is standard and in 100 percent of pipes of gravity distribution network is less than standard.Conclusion: Comparing the parameters of pressure, leakage rate, water age and rate of remained CL between two systems of gravity distribution and direct pumping, this study indicated that all of these parameters in direct pumping network are in better conditions and closer to its standard rates.Key Words: Leakage, Water Supply System, Distribution Network, Remained CL, Water Gems
