The present invention relates to a method for monitoring the operation of a pumping station (1), wherein the pumping station (1) includes: a storage tank (6) for temporarily storing liquid; an inlet (7) for liquid inflow; an outlet (8); and at least one pump (2) configured to deliver liquid out of the storage tank (6) through the outlet (8). The method is characterized by the following steps: monitoring the inflow of liquid into the storage tank (6) for at least a portion of a predetermined time period (T) and determining inflow data (IN) representing the amount of liquid flowing into the storage tank (6) of the pumping station (1) during the predetermined time period (T); determining pumping station maximum capacity data (PSMC) representing the maximum capacity of liquid pumped from the storage tank of the pumping station (1) during the predetermined time period (T); and, for the predetermined time period, using the general formula PSCU based on the determined values ​​of the inflow data (IN) and the pumping station maximum capacity data (PSMC). M (%) = 100 * IN / PSMC to determine the instantaneous pump station capacity utilization rate (PSCU) M ); and based on at least one instantaneous pump station capacity utilization rate (PSCU) M The value is used to determine the typical pump station capacity utilization rate (PSCU) of pump station (1). T The typical pump station capacity utilization rate (PSCU) T This indicates the capacity utilization rate of the pumping station over a period of time.
