ABSTRACT:
A method is provided for disposing of sewage from multiple household connections. A specific volume of sewage is first collected and then suctioned off by means of a vacuum, air being released into the vacuum pipe after the sewage. The method is characterized in that the collection of the sewage takes place at each house individually and in small amounts (about 5 to 30 liters) and in that the amount of the air subsequently released into the vacuum pipe amounts to two to fifteen times the volume of the sewage.
