Abstract

Due to the special topography of Kaleybar city, the water distribution network of this city has 7 pressure-reducing valves that have been experimentally installed in different locations to manage the extra pressure in the network. In this research, the effect of the intelligent emplacement of pressure-reducing valves is investigated by using the valve selection index to reduce leakage and increase network reliability. The aim is to minimize hourly leakage by determining the optimal location and setting of valves, In addition to the minimization of leakage as the objective function, the minimum pressure restriction in three cases of no pressure restriction (0 meters), water supply at the entrance of the building (10 meters) and water supply for a four-story building (26 m) is considered as a penalty function. For this purpose, a combination of the Ant Colony Optimization Algorithm with the EPANET simulator in MATLAB has been used. The results show that with the intelligent emplacement of pressure-reducing valves in Kaleybar City, the leakage of the network has been decreased by 15.9 percent and the reliability of the network has been increased by 15. 5 percent, which shows the effect of the proposed method in improving the hydraulic performance of water distribution network.
