Fresh water is distributed in an aircraft from at least one supply tank connected through a conduit to at least one water using device, such as a tap, faucet, or the like. The conduit is constructed as a ring conduit, which is provided with or connected to a water conveying device, such as a pump, suction, or pressurizing device. One or more water using devices are connected to the ring conduit by respective branch lines.

Fresh water supply system for an aircraft

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.

Used or waste water collection system for an aircraft

A fresh water supply system for an aircraft has at least one supply tank connected to one or more water taps or faucets through a main line, including a device for conveying the water, for example by a pump, by suction, by pressure, or even by gravity. An auxiliary tank or reservoir is arranged near a tap or faucet, and the auxiliary tank is connected to the main line by a controllable valve. The conveying device is connected with a control, which operates in such a way that the main line is filled with water only during first time durations while it is filled with air during second time durations. A venting valve is connected to the main line to permit the venting of the main line when water is removed from the main line. Air also escapes through the venting valve when the main line is being refilled with water.
