Based on the consideration of the flow changing process of pumping station, a linear programming model of the optimal design of pressurized water conveyance pipeline system is established. Under the condition of ensuring the flow and pressure of water supply in each stage, the optimum value of the required lift and the size of each pipe segment can be determined in each water supply phase, so that the annual system cost is minimized. The results can provide a scientific basis for the design and operation of pressurized water conveyance system in pumping stations.
