UNTERDRUCK-ABWASSERANLAGE

摘要

A vacuum sewer system and a method of operating such system is disclosed. The system includes a sewage holding tank and a lateral flow line and a vacuum valve associated with the holding tank for permitting a quantity of wastewater to be drawn out of the holding tank by a vacuum environment. The wastewater is drawn through the lateral flow line and a main pipeline to a desired collection location. A plurality of air inlet valves are arranged at spaced locations along the main pipeline for facilitating the flow of wastewater through the lateral flow line so that a large volume of the wastewater can flow through the lateral flow line in a given time.
