In the process of practical operation and management, the operating-mode adaptability of multi-source water supply system is researched to satisfy the mode-transformation demand. Based on the microscopic model, the two-stage optimal operation model which has the operatingmode adaptability is established and solved by genetic algorithm. On this basis, the optimal operation on transformation mode can be realized and provide the evidence for optimal operation decisionmaking. The model is applied to the optimal operation of one city water supply system. The practice proves that this model can satisfy the mode-transformation demand of pump stations; at the same time, it can also ensure water supply safety and reduce the operation consumption.
