Application
When new building zones are opened up, it is often quite expensive to build a sewerage network with the necessary downward slope. In such cases, a vacuum sewerage network offers an interesting alternative to traditional sewer systems. The wastewater is transported to the pumping station under vacuum, which allows significantly smaller pipes to be used and stretches of upward slope spanned. A central vacuum pumping unit conveys the wastewater from households via a central sewage discharge into the public sewer system. To effectively control the system the level in the vacuum tank must be continuously monitored.
