ABSTRACT:
The invention relates to a sewage system comprising a sewage producing unit, a vacuum creating apparatus, an intermediate tank, a receiver and pipe connection means interconnecting said parts. The sewage is arranged to be carried away from the sewage producing unit into the intermediate tank by means of vacuum. To minimize smell problems, exhaust air from the vacuum creating apparatus is arranged to be passed into a pressure accumulator. The compressed air stored in the pressure accumulator is arranged to be passed into the intermediate tank so that it passes the sewage contained in the intermediaate tank into the sewage receiver.
