The study has been carried out in two phases. In the first phase, a model of pipe network is developed based on EPANET (Version 2.0) in such a way that the modeled flow data for various zonal overhead reservoirs takes almost equal fill up times by adjusting the flow control valves and changing some other parameters such as flow parameter of flow control valves, loss coefficient of throttle control valves etc. In the second phase, a lot of modifications have been done by adjusting different parameters of TCV, PRV and FCV for optimizing the head losses in pipes and valves in the modeled system so that the desired water inflow to the zonal overhead reservoirs is achieved.
