All vacuum sewer lines are connected to the vacuum collection vessel installed at the central vacuum station, where vacuum pumps create the required negative pressure (approx. –0.6 bar). The vacuum vessel can be placed inside or buried outside the vacuum station. Discharge pumps transport the wastewater from the vessel to the wastewater treatment plant or to an existing sewer.
The capacity and dimension of the vacuum station depend on the particular requirements of the sewer system. Operation of the vacuum and discharge pumps is controlled through a PLC with the RoeVac® software designed to ensure optimum demand-driven operation. A standard “compact vacuum station” can be delivered prefabricated and tested for small sewer systems to service a small number of houses in villages or buildings on industrial estates. Individual design and construct services can be provided for vacuum stations for hundreds or thousands of houses and buildings.
