Increasingly, water loss via leakage is acknowledged as one of the main challenges facing WDS (water distribution system) operations. The leakage is losses of an economy, an energy and a water resource. The pressure management is known as one most cost-benefit method in the currently available methods of leakage reduction and prevention. In this paper, an optimization model of water pressure in WDS was developed which was considered a PRV (pressure reduction valve) as a way of pressure management. Xu-Jowitt (1990) model was used to consider a pressure-dependent leakage, GA (genetic algorithm) was used to search a optimal location and numbers of PRV and LP (linear programming) was used to solve a valve control. The model results was compared to EPANET's simulation results for an example network to verify a robustness.
