A wastewater tank arrangement for an aircraft, including a wastewater tank and a drain pipe having a first end and an opposite second end, the drain pipe fastened with its first end to the wastewater tank and having a second end for connection to a service panel in the aircraft structure. Providing a wastewater tank arrangement can effectively compensate tolerances between the wastewater tank and the service panel, and can effectively compensate installation and manufacturing tolerances during the course of the initial installation, in that the wastewater tank arrangement has a tolerance compensation device configured to connect the second end of the drain pipe to the service panel and compensate tolerances between the second end of the drain pipe and the service panel.

A combined toilet grey water system for passenger transportation vehicles such as aircrafts includes a toilet bowl for receiving waste water and a basin for receiving grey water. Moreover, the system includes a flushing line and a flushing valve with an inlet and an outlet. The outlet of the flushing valve is connectable to a vacuum waste water system. The inlet of the flushing valve is connected via the flushing line to the toilet bowl. Therein, the basin is connected to the flushing line in such a way that the basin is connectable to the vacuum waste water system.

A measurement system for determining a liquid fill level of a tank, including a floating sensor configured to float on the surface of a liquid contained in the tank, at least three reference sensors mounted at a hull of the tank in a spatially fixed arrangement, and a control device to control the floating sensor and the reference sensors, wherein at least one of the floating sensor and the reference sensors can emit an acoustic signal to the remaining sensors, wherein the remaining sensors can receive the emitted acoustic signal, and wherein the control device is configured to determine signal travelling times of the acoustic signal from the emitting sensor to the receiving sensor, to compute a spatial position of the floating sensor with respect to the reference sensors from the signal travelling times, and to determine the liquid fill level using the computed spatial position of the floating sensor.
