Abstract
Water distribution networks are among the most critical urban infrastructures, with leakage being a major challenge. Pressure control and management have been identified as effective strategies for reducing leakage. In this study, a hydraulic model was developed for two networks, Jowitt & Xu and a section of the Tehran water distribution network, using WaterGEMS. The optimal location and outlet pressure of pressure-reducing valves (PRVs) were determined as an optimization problem using the MOPSO approach. A MATLAB-based program was designed and integrated with the EPANET hydraulic analyzer for implementation. The results were evaluated and ranked using the VIKOR and TOPSIS methods. Ultimately, the optimized placement of 9 PRVs ensured that 80% of the network nodes-maintained pressure within the standard range, compared to only 65% coverage with 14 PRVs in the initial network condition.
