Abstract In order to improve the operating efficiency of the pumping station in the pumping station-reservoir raw water transfer system, the operating cost of the water transmission system must be minimized. By analyzing the characteristics of this type of water transmission system and the water supply mode, and based on the genetic algorithms, the flow distribution model of the pumping station unit was constructed to optimize the distribution of the operating flow of the pumping station. On this basis, considering the operation mode of the pumping station in the time dimension, combined with the enginee-ring status of the Bozhou pressurized pumping station and the regional time-of-use electricity prices, an economic operation model was constructed with the minimum unit water lifting cost as the optimization goal. This method was applied to the Bozhou Water Supply Project, and the results showed that the model had a significant effect, and the periodic water transmission volume within the historical opera-ting interval was discretely calculated. The results show that the constructed economic operation model has good applicability, which can reduce the project operation cost and provide guidance for the optimal scheduling of the project. Affected by the operating efficiency of the pumping station and the time-of-use electricity price, the unit water lifting cost of the pumping station first decreases and then increases with the increase of the water transfer volume.
