PROBLEM TO BE SOLVED: To provide the operation controller for a drainage pumping station which can optimally control the drainage from a tributary river to a main stream river, by appropriately controlling the operation of a sluice gate and a drainage pump during a typhoon, heavy rain, torrential downpour, or the like. SOLUTION: In the operation controller for a drainage pumping station having a sluice gate 13 located in the confluence from a tributary river 12 to a main stream river 11 and a drainage pump 15 located in a sluice 14 which bypasses the sluice gate 13 from the tributary river 12, a water gauge 17 is arranged near the confluence from the tributary river 12 to the main stream river 11, and a flow direction meter 19 for detecting the flow direction of this tributary river is arranged in the tributary river. When a water level measured by the water gate 17 is lower than a set water level, a control circuit 21 controls the sluice gate 13 to an open state and the drain pump 15 to a stop state, and when a water level measured by the water gauge 17 is higher than the set value and a direction measured by the flow direction meter 19 is in a reverse flow state or a stop state, it controls the sluice gate 13 to a closed state and the drainage pump 15 to an operation state.
