A sewer system in which partial vacuum is used for transporting sewage through a sewer pipe to a collecting chamber or the like. The system comprises only a few sewage producing units, preferably only one at a time usable unit. The length of the sewer pipe from a sewage producing unit to the collecting chamber is comparatively small and the operating devices of the system are arranged to generate vacuum in the sewer pipe principally only for the time required for transporting each separate sewage discharge emitted into the sewer pipe. Preferably, the operating devices are arranged to stop generating the vacuum before the actual transport of the sewage takes part.

A sewer system including means for generating a partial vacuum for transporting sewage through a sewer pipe to a collecting chamber for an installation comprising a small number of sewage producing units, preferably only one of said sewage producing units being usable at a time, said sewer pipe between each said sewage producing unit and said collecting chamber having a small total volume, control means for starting and stopping said partial vacuum generating means, and means for activating said control means for generating a vacuum in said sewer pipe principally only for the time required for transporting each separate sewage discharge from a selected one of said small number of sewage producing units to said collecting chamber, and said sewer pipe being otherwise under a higher pressure.
