In a method for determining a filling level (F) of waste water (8) in a tank (6) of a vehicle (2), wherein a respective flushing quantity (P) of waste water (8) is fed to the tank (6) by means of flushing processes, a binary filling signal (La-e) (waste water (8) present or not) is determined at at least two measuring positions (20a-e) at the tank (6) with known filling quantities (Ma-e), the filling level (F) is determined as a sum of a basic filling quantity (B) and an inflow quantity (Z), wherein the basic filling quantity (B) is selected as zero or as the greatest filling quantities (Ma-e) of active filling signals (La-e) at a starting time (A), and the inflow quantity (Z) is determined as a sum of all the fed-in flushing quantities (P) from the starting time (A).A measuring arrangement (12) for determining the filling level (F) contains an evaluation module (14) with an interface (16) for the flushing signals (S), and at least two sensors (18a-e) for the filling signals (La-e), wherein the evaluation module (14) is designed to determine the filling level (F) according to the method according to the invention.A waste water arrangement (4) with the tank (6) and at least one flushing device (10) contains a measuring arrangement (12) according to the invention.
