Yesterday, while I was traveling via airplane, I came across something that made me wonder, "How does the toilet in the plane work?" And I couldn't stop myself from writing this article. The toilets of the washroom do not have the bowl like the common toilets. Strange, isn't it? Then how does it work?
Don't worry, read on to the story to know the answer!
..uses a bowl filled with water so that when you flush the toilet, it starts pumping that drains the bowl. The water is then carried into the septic tank.
..doesn't have the bowl of water. Then how does it get emptied?
..because they use an active vacuum instead of the siphon so that when you flush, a valve gets opened in the sewer line and the contents of the bowl get transferred into the tank.
Since the vacuum does all the work, very little water is required to clean the bowl. A vacuum system just requires half a gallon (2 liters) of fluid or less as compared to a typical toilet, saving up to 5 gallons (19 liters) of water.
A lot of water can be saved as they use very less water.
They use very small diameter sewer pipes.
It can be flushed in any direction, even upwards. Since a vacuum system does not use gravity for the movement of water, nothing can stop the sewer pipe from going straight up.
They can be put anywhere in the building.
