A triple authentication waste level monitoring system for an aircraft includes a point level sensor (114) for monitoring a wastewater level within a waste tank (110), a load cell (130) for measuring a weight of the waste tank, and a flush counter (240) for counting a number of toilet flushes since a previous service to the waste tank. A controller (230) receives data from these three sensors and determines whether the waste tank is at capacity. The controller (230) can determine waste tank capacity whether or not the point level sensor (114) is faulty and compares the sensor data with various thresholds to ensure accuracy of the waste tank fluid level determination.
