PROBLEM TO BE SOLVED: To hold a water level of a pump well in a specific range, by adjusting the number of operation platforms of a pump in response to a predicted inflow quantity, while preventing an increase in a business burden of an operation operator, an increase in an electric power using quantity and the occurrence of a flooding accident, by maintaining the operation content of the pump as it is, when the predicted inflow quantity is temporarily increased or reduced. SOLUTION: This pump operation support device is constituted so that an inflow quantity predicting part 15 predicts an inflow quantity in a predicting range on the basis of respective measuring results; when the inflow quantity increases in the whole section in the predicting range and a predicted water level exceeds a pump operation water level, or when the inflow quantity reduces in the whole section in the predicting range and the predicted water level is less than a pump stopping water level, this fact is detected by an arithmetic operation part 16; and pump operation guidance and pump stopping guidance are outputted from an operation support part 17 and a controller part 18, to prevent an actual water level from falling off out of the specific range.
