Abstract :
Water distribution network is a system consisting of pipe, water reservoir, pump and valves. Water-supply networks in the hydraulic systems for water transmission and distribution have always been considered by researchers. The hydraulic behavior of water transmission lines is based on speed, pressure and flow. The possible changes in the consumption pattern, population, network leak and diameter of pipe line as well as potential of pumps need to be reviewed. In this research, the evaluation of hydraulic management of urban water-supply networks was carried out using Water Gems software. This means that the diameter of pipe lines and the level (height numbers) are changed so that the pressure is reached to the standard level in the network. Additionally, with modeling this township in Water Gems network in addition to the management of pressure, other data including speed, flow and demand rate are also provided. The first mode is based on the true state of water and sewage network was modeled in Semnan province. The second mode network according to the first mode was modified by changing the diameter of the pipes used to supply standard pressure and negative pressures were destroyed. In the second case by changing the elevation of the standard pressure of the atmosphere was 5-7. The optimum diameter of 85 mm and 180 mm was determined. optimized elevation for reservoir is 1430 meters and by increasing, the low pressure or by reducing, the pressure level rises.
