An alarm management module (13) is for a wastewater pumping station that includes at least one pump (9a, 9b) arranged for pumping wastewater out of a wastewater pit (1). The alarm management module (13) is configured to process at least one level variable (h) indicative of a filling level of the wastewater pit (1) and at least one capacity variable (p %, P %, C %) indicative of a pumping capacity of the wastewater pumping station. The alarm management module (13) is configured to trigger an intervention alarm only if all of the following conditions are met: a) the at least one level variable (h) is at or above a predetermined alarm level threshold (hm), b) the at least one level variable (h) is increasing, and c) the at least one capacity variable (p %, P %, C %) is below a capacity threshold.
