The main aim of an optimal schedule of conventional multi-source water distribution system is to reduce the energy consumption rather than minimizing the network leakage. This research is on the premise of meeting water demand, pressure and water quality considering the states of valve opening and closing, the states of pump opening and closing, and the pump speed as solution space. The optimization objectives are to minimize the network leakage and power consumption and to find the optimal valve closing scheme for network partitioning and the optimal pump scheduling scheme. NSGA-II algorithm is employed for solving the optimization problem. The obtained network partitioning and pumping scheduling solutions are applied to a real water network in Changping town, and the results prove that this method can simultaneously reduce the power consumption and network leakage.
