Introduction
Vacuflow® is a unique vacuum sewer system developed by Qua-vac. Vacuflow® operates largely without electricity. It also has a long service life and low maintenance costs. Vacuflow® can be used in a wide variety of settings, but is particularly valuable in locations where major and costly construction work needs to be avoided.

What is Vacuflow®?
Vacuflow® is an innovative vacuum sewer system that can be used in more complex areas, such as locations with high groundwater levels, rocky terrain, coastal areas, islands, or vacation resorts. It allows for construction using narrow and shallow trenches and offers great flexibility during installation.

How does Vacuflow® work?
The Vacuflow® system basically consists of three elements:
- A collection chamber with interface unit
- A vacuum piping
- A vacuum station
Collection chamber
Vacuflow® works with a collection chamber, a vacuum piping transport, vacuum station and vacuum tank. In that precise order. Sewage flows by gravity into a collection chamber, which stores the sewage. When the level of sewage rises to a high level, the air and sewage will be drained into the vacuum network. A float activator ensures that this ‘high level’ is reached. Good to know, that in the collection chambers, no electricity is involved.
Vacuum piping
Once the sewage has entered the network, the transport continues through the piping system. Another great advantage of the Vacuflow® is that this sewerage system can be installed in shallow trenches. The sewerage system can be laid at a depth of 80 – 120 centimeters.
Vacuum station
When the sewage reaches the vacuum station, it ends up in the vacuum tank via the pipe network. Optionally, a sewer management system called Vaculink can be installed on the vacuum tank and on the collection chambers. This can monitor the whole system. How high the water level is, whether there are problems and so on.
Sewerage management with Vaculink®
- Online webportal
- All data 24/7 easily available
- User defined configuration
- Alerts via SMS or e-mail
Vaculink® always provides 24/7 insight into the system, real-time data and the current water level. But, in case of any problems: quick signaling, specific indication where the problem is located and alarm notification via SMS or email. In addition, the web portal can be configurated just the way you like!
The benefits of Vacuflow®

- Station, valve and high level monitoring
Vacuflow® method
Sewage flows by gravity into a collection chamber. This collection chamber stores the sewage for a short time, with reserve storage availability. When the level of the sewage inside the collection chamber rises, a starter valve activates the vacuum piston valve to open which allows the content together with air to be drained into the vacuum network. This system has the advantage that more properties can be connected to one collection chamber. The mechanisms in these collection chambers work pneumatically / mechanically, which has the advantage that no electricity is needed.
The pipe network consists of PVC or HDPE pipes. A central vacuum station keeps this pipe network under negative pressure. Due to their small diameter, the pipes can be laid at depths of 80 to 120 centimeters under the ground surface. The addition of air makes the wastewater lighter, which leads to higher transport speeds. The pipe network is laid in a ‘saw tooth profile’. Within this profile, a mixture of wastewater and air from the collection chamber is transported to the vacuum station.
The waste water from the collection chamber ends up in the vacuum tank via the pipe network. The vacuum in the tank is generated by vacuum pumps. The extracted air can, if necessary, be purified through a filter. The level in the tank is measured with a Radar level measurement. At a high level, the pressure pump (s) starts and the waste water is transported to a sewage treatment plant or discharge point in the area. The discharge pump (s) stop at a low level.
Qua-vac has an extensive network of Vacuflow® distributors around the world, as well as a large number of design and manufacturing partners in European countries.
