1. A wastewater pumping station comprising:
two or more pumps arranged for pumping wastewater out of a wastewater pit into a pipe; and
a monitoring module for identifying an operating scenario in a wastewater pumping station, wherein the monitoring module is configured to process at least one load-dependent pump variable for each running pump of the two or more pumps indicative of how a respective running pump operates and to process a first of at least two model-based pipe parameters indicative of how the wastewater flows through the pipe and/or the pumps, and to process a negative-flow parameter as a second of the at least two model-based pipe parameters, wherein the negative-flow parameter is indicative of how the wastewater flows through the pipe and/or one or more non-running pumps of the pumps when at least one of the pumps is stopped, wherein the monitoring module is configured to identify an operating scenario in the wastewater pumping station by selecting an operating scenario from a group of predefined operating scenarios dependent on at least one first criterion for each running pump of the pumps that is based on the at least one load-dependent pump variable, at least one second criterion that is based on at least the first of the at least two one model-based pipe parameters and at least one third criterion that is based on the negative-flow parameter.
