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
When 10 gallons of wastewater
collects in the sump, the AIRVAC valve
opens and differential pressure propels the contents into thevacuum
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 thevacuum 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.
