This must be a topic you haven’t given much thought about – how does the toilet on a modern aircraft work? What does the built-in system do with your waste, once you are done going for a number two? In this article, this complicated system of waste management is going to be explained, alongside a few bonus bits of information that is going to expand your knowledge of how a modern airliner works. Let’s begin with the photos.
Don’t Worry About It
There are some people who worry about going for a number two on an airliner. This is because they fear that their waste is going to “drop” somewhere on the ground. The good news is that that’s not at all how the waste management system works.
You May Be Wondering Where the Poop Goes
You may be wondering, just how does the airplane’s system and plumbing works, and where does the poop go. To simplify the explanation, the poop goes from your belly, into the airplane’s belly. After that is where the true magic happens.
The Airplane Has a Number of Tanks
The previous picture’s description mentioned something about the “airplane’s belly.” That’s completely true, and that belly is just one of several tanks found inside the plane. These tanks get filled with waste, through the use of suction.
Pressing the Flush Button
Pressing the flush button in the airplane’s toilet is the first step of the process. Pressing that button opens a valve on the bottom of the bowl, which in turn exposes the contents of the bowl to a pneumatic vacuum.
There Are Suction and Holding Tanks
There are two types of tanks in the plane – suction and holding tanks. The differences between them doesn’t matter, but what matters is that you don’t want to overfill the holding tanks. Once that happens, they may start dropping waste outside of the tank’s storage.
