A sanitary installation in which waste water is conveyed to a pipe system during the simultaneous supply of air. The pipe system includes a generally vertical long length of pipe which is closed at its upper end and open at its lower end. Waste water and air is introduced in the upper part of the pipe whereby air is separated and removed by means of a vacuum pump connected to the upper part of the pipe. Waste water is further collected in the form of a standing liquid column in the lower part of the vertical pipe and is successively caused to flow to a holding tank.

A method of conveying waste water with the aid of a vacuum source from a plurality of sanitary installations through a system of conduits to a holding tank, or the like, comprising: transferring waste water in the form of a plug from said sanitary installations to said conduit system by operating a valve means during the simultaneous introduction of air into the system behind said plug, said conduit system including a relatively long pipe which is disposed generally vertically and is closed at its upper end, introducing said plug and air in the upper part of said pipe in such a manner that air is continuously separated from the waste water and removed by means of a vacuum pump, which applies a vacuum to the upper part of said vertical pipe, said waste water falling by gravity down said vertical pipe to be collected in the form of a standing liquid column in the lower part of said vertical pipe, said liquid column being of such a height that it is balanced by the vacuum prevailing in the upper part of said vertical pipe, said lower end of the vertical pipe being open and submerged within said holding tank, said standing liquid column being caused to flow to said holding tank, and a water seal in the lower part of said pipe preventing the entrance of air therein.
