Abstract: A method for monitoring the operation of a pump station comprising a tank for temporary storage of a liquid, an inlet for influent liquid, an outlet, and at least one pump configured for transporting the liquid away from the tank via the outlet. The method comprises steps. Monitoring an inflow of liquid to the tank during at least a part of a predetermined time period (T) and determining Inflow data (IN) representative of the inflow during T. Determining Pump Station Max Capacity data (PSMC) that is representative of the max capacity of pumped liquid from the tank during T. For T, determining a momentary Pump Station Capacity Utilization (PSCUM) based on IN and PSMC, using the overall formula PSCUM (%)=100*IN/PSMC. Determining a typical Pump Station Capacity Utilization (PSCUT) for the pump station based on at least one momentary PSCUM value.
