How does a vacuum toilet work?
In a vacuum toilet, wastewater is not flushed away but sucked away. The toilet is connected to a pipe network that is kept under negative pressure by vacuum pumps. As soon as you press the flush button, a valve opens and the wastewater is quickly and forcefully carried away.
Because air is the primary means of transport, a vacuum toilet uses only 1.2 liters of water per flush, compared to 3 to 6 liters for a conventional toilet. Modern vacuum toilets are also quieter than many people expect, because the technology and conditions differ significantly from those in airplanes and trains (which is what most people think of when they hear “vacuum toilet”).
Direct transport to vacuum station
The vacuum toilet is directly connected to the vacuum sewer system. The wastewater is routed to the vacuum station without the need for additional pumps or sumps and is transported from there to a local treatment facility, storage facility, or wastewater treatment plant.
