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.
Claims9
A waste water collection system in an aircraft, comprising at least one waste water discharging sink (8, 9), a waste water collection tank (17, 42), an individual pipe section (14A) communicating said waste water discharging sink with said collection tank (17, 42), a controllable valve (38) connected in said individual pipe section, at least one toilet (13), a toilet effluent conduit (14) connecting said toilet to said collection tank (17, 42), suction means (18) connected to said system for transporting waste water from said waste water discharging sink and from said toilet into said collection tank, said suction means (18) constantly maintaining a reduced pressure in said system for said transporting and for suppressing an odor emission, and valve control means (40, 41) connected to each said control valve (38) in said individual pipe section for individually controlling an application of suction to said system for said transporting, said valve control means controlling said controllable valves (38) in such a way that only one valve (38) is open at a time, whereby clogging of said system and or escape are prevented.
