Abstract of the Disclosure A vacuum drain sewage facility is disclosed, having a plurality of house connections in which relatively small amounts of water collected at the house connections are admitted into the vacuum conduit of the system, followed immediately by a volume of air from two to fifteen times the liquid volume. The vacuum conduit is connected to a collecting tank that is under vacuum. The conduit has ascending and descending sections, the vacuum conduit in the vicinity of the house connections being laid out in the direction of flow with relatively short ascending sections and relatively long descending sections, the descending sections being at least twice as long as the ascending sections. The length of the ascending conduit sections is from one to twenty meters, with the rise of the ascending conduit sections being 0.85 to 5 meters. The ascending conduit sections preferably are of smaller cross section than the descending sections.
