Abstract

Water distribution networks are one of the most critical infrastructures in urban systems, the use of which has always been associated with many challenges. These networks are encountered frequent problems such as pipe breaks, water leakages, and non-uniform nodal pressure distribution. In this study, a time-based scheduling approach is presented for the use of pressure control equipment in water networks. Two operational scenarios consisting of the simultaneous use of individual pressure-reducing valves in the first scenario (individual scenario) and the hybrid use of pressure-reducing valves with a variable speed pump in the second scenario (hybrid scenario) are investigated. In this case, operational programs are developed to control nodal pressures in the network for providing minimum temporal and spatial pressure variations, using a Genetic algorithm as an optimization tool. The proposed strategies based on dual scenarios were validated for both theoretical and real networks. The optimal scenario was determined by calculating the hydraulic evaluation indicators of each scenario. The results show that the simultaneous use of pressure-reducing valves and variable speed pumps (hybrid scenario) was more effective in pressure management, in comparison with the individual scenario.
