Houses or buildings are connected to a Vacuflow Collection chamber where the wastewater is collected by gravity. The Vacuflow Collection chamber has a vacuum valve that is automatically activated when wastewater reaches a certain level.

The Vacuflow collection chamber has great advantages:

  • No electricity
  • Batch volume of 30-120 litres
  • Fully submersible valve and level controller
  • No “breather pipe” needed
  • Material of chamber PE/PP or Concrete
  • Transport of air and water simultaneously
  • Buffer capacity of the complete chamber

QUA-VAC has several different Vacuum valves sizes but most commonly used are the 63mm and 90mm for transport of sewage outside buildings.
