How The Flovac Vacuum Works

  • Sewage flows by short gravity pipe work from homes into a collection chamber.
  • When approximately 80 litres accumulates in the sump, the vacuum interface valve (located above the sump) automatically opens and differential air pressure propels the sewage through the valve and into the vacuum main.
  • Sewage flows through the vacuum lines and into the collection tank at the vacuum station.
  • The sewage pumps transfer the sewage from the collection tank to the wastewater treatment facility or nearby gravity manhole.
  • There are no electrical connections required at the collection point, only at the vacuum station.
  • Monitoring is highly recommended, especially for longer systems.
