LOW-PRESSURE DRAINAGE SYSTEM

摘要

The invention relates to a low-pressure drainage system, in particular for the drainage of housing settlements, comprising a low-pressure conduit which opens into a main collection container that is connected to a source of low-pressure, such as a pump. Several waste-water collection containers can be connected to the low-pressure conduit, each using a respective stop valve which can be actuated by a control device (217). The low-pressure conduit is laid with an angular profile which has elevated points and low points that allow waste water to collect. The invention aims to improve a corresponding low-pressure drainage system so that it functions more efficiently. At the same time a favourable air-water ratio should be achieved during the transport of the waste water. To this end, the low-pressure which continues as far as the control unit is restricted.
