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.

A method of operating a vacuum sewer system for withdrawing wastewater from a sewage holding tank through a lateral flow line into a main pipeline, said method comprising the steps of: creating a vacuum environment in said main pipeline and said lateral flow line; selectively subjecting wastewater retained within said sewage holding tank to said vacuum environment for a period of time sufficient to force substantially only wastewater to flow out of said sewage holding tank and into said lateral flow line but insufficient to permit an appreciable amount of air to flow from said sewage holding tank; and selectively admitting air directly into said main pipeline thereby enhancing the flow of the wastewater flowing within said lateral flow line.
