Abstract
A used or waste water collection system for an aircraft has a waste water collection pipe that connects a kitchen sink with a collecting tank through a controllable valve. The waste water is transported by reduced pressure. For this purpose, the collecting pipe is connected to the suction system present in the aircraft, especially for removing sewage from the flushing of a toilet basin in the aircraft.
