HOW DOES IT WORK?
MUNICIPAL VACUUM SEWER SYSTEMS
VACUUM SEWER SYSTEMS 
For the customer, an AIRVAC system works just like any other sewer system. Traditional gravity lines carry wastewater from the source to an AIRVAC valve pit.
When 10 gallons of wastewater collects in the sump, the AIRVAC valve opens and differential pressure propels the contents into the vacuum main.
Wastewater travels at 15 to 18 feet per second in the vacuum main to the vacuum station. The vacuum main is laid in a sawtooth fashion to ensure adequate vacuum levels at the end of each line.
At the vacuum station, vacuum pumps cycle on and off as needed to maintain a constant level of vacuum on the entire system. Wastewater enters the collection tank and when the tank fills to a predetermined level, sewage pumps transfer the contents to the treatment plant via a force main.
IS VACUUM RIGHT FOR YOU?
If your project has any of the following conditions, then vacuum sewers are the solution for you:
• At Least 75 Connections • Rolling Hills with Small Elevation Changes
• High Groundwater Table • Flat Terrain
• Restricted Construction Conditions • Unstable Soils
• Rock • Sensitive Eco-system
AIRVAC’s typical project has one or more of the above difficulties, most likely has experienced failing septic tanks, and is in a suburb of a city. However, having completed projects in every imaginable environment, AIRVAC has been able to customize its product to fit virtually any customer need.
Vacuum sewers are also particularly well suited for private developments as they offer some unique benefits and advantages, many of which are green.
