Airvac vacuum sewer collection system
Airvac’s vacuum sewer collection systems are a mechanized method of transporting wastewater. Differential air pressure creates flow rather than gravity or pressure. Essentially, a vacuum sewer collection system is a vacuum-assisted gravity sewer system. Systems require a vacuum station. Vacuum pumps at the vacuum station maintain vacuum on the collection mains. To maintain this vacuum, a valve at each sewage input point seals the system. The valve opens automatically when a given quantity of sewage accumulates in a collection sump. This valve is entirely pneumatic in its control and operation. Differential pressure between local atmospheric pressure
