A vacuum toilet is quite similar to any normal flush toilet. However, a it uses under pressure technology in flushing and as result, much less water is needed to move the waste in drainage.
Most people have seen the same technique used in trains, airplanes and ships – although in domestic use the vacuum is only used for few seconds during flushing.
The greatest advantage of vacuum toilets is that they minimize the water consumption needed for flushing. The waste is moved in the drainage by strong air suction and therefore water for flushing is needed few deciliters only. This feature is particularly advantageous in summerhouses and other areas without a connection to a centralized sewage system. Most commonly, the waste is being collected to a septic tank outside the house. The septic tank can be emptied for example once a year with special truck.
Where vacuum toilet fits the best?
A vacuum toilet is the best option if you are looking for a toilet alternative that is as close to a normal flush toilet as it can be without the need to join in a centralized sewage system. Whenever there is need to minimize the flushing water consumption, the vacuum toilet is a good option as they use so little water. The toilet brings savings when you do not need to use so much water for flushing and empty your septic tank that often. Also, the energy consumption is significantly lower than for example with the electric incinerating toilets.
