Claim:
1. A method for operating a wastewater pumping station of a wastewater pumping network, the wastewater pumping station comprising at least one pump, wherein the at least one pump starts pumping if a level of the wastewater in a tank of the wastewater pumping station exceeds a first wastewater level, and the at least one pump stops pumping if the level of the wastewater in the tank drops below a second level, the method comprising the steps of: determining a magnitude of a parameter expressing the load in a common pipeline of the wastewater pumping network; determining if the magnitude of the parameter expressing the load has passed a specified threshold; and activating the at least one pump to start pumping in an energy optimization mode if the parameter expressing the load has passed the specified threshold, wherein the specified threshold of the load expressing parameter is determined by measuring or deriving the size or value of the parameter during each of a plurality of activations of the at least one pump to provide a plurality of sizes or values of the parameter, and then selecting or calculating the specified threshold on the basis of the sizes or values.
