Abstract: Pressure management is a widely adapted technique to decrease background leakage or to extend the lifespan of the pipe network[1]. In some cases, it is inevitable to deploy multiple pressure reducing valves to supply a particular zone. In order to supply water to the customers with optimal pressure head, the precise setting of the parallel pressure reducing valves’ (PRV) target pressure is required. Steady state hydraulic models like EPANET has the functionality to simulate pressure loss of a pressure-reducing valve[1]. This can be simulated by adding minor-loss after the pipe, or by modifying the properties of the next link on the downstream side. Either way proper setting of the coefficients are essential to calibrate the hydraulic model. In this paper, two non-linear optimization methods were utilized to calibrate the hydraulic model with multiple input values.
