I haven't had to take a dump on an airplane in years. My rule is to eat and drink as little as possible before a flight, ideally not eating at all. If I do eat, hopefully it's high protein and low in fiber. As a result I usually don't need to use the lavatory, which is nice because it has made me much less apprehensive about getting a window seat. I wish more people had this mindset. On so many flights I've had, seem…

* My only explanation is that they're overnourished on the Standard American Diet. Imagine how much less waste would have to be pumped out of airplanes.* A lot of folks poop on a schedule: Making sure you don't poop on the plane might very well involve adjusting food for a few days before a flight, depending on how often you poop. Some folks poop multiple times a day, some folks poop a few times a week. Some women po…

But that's exactly the reason why healthy people, whatever healthy means, should starve: If those who can control their asses do so, then there are more toilets available to those in need.

I can't even understand why people are eating/drinking in planes, I haven't take a flight since several years but usually you've a bit of adrenaline, thus no hunger

Flying dehydrates you - the cabin is pressurized by constantly pumping outside air into the pressure vessel that is the fuselage, and the air at cruising altitudes is extremely dry in addition to having less oxygen than we are accustomed to at ground level. We increase our respiration rate due to the lower oxygen content, and lose a fair amount of water in the process as the dry air drains it from us.

I've never been on a flight long enough that I needed to eat, but even on a regional flight I find myself wanting at least something to drink because my throat feels a little dry.

Two billion litres a year. Impressive number at first glance. But let's say my own household of 4 was able to keep water consumption down to 500L/day (I wish), that's already around 180K litres/year just for my house. So divided into 2B, that's about 11K houses' worth of wastewater. A modest size town's worth, for all the air travel worldwide.

I would suggest that this is actually more efficient. When people use the toilet on planes, the design of the toilets uses so much less water than a toilet on the ground, in the airport, and how much a flush of water takes. So if you assume that people were going to use the bathroom regardless, they just saved the processing of a lot of water by doing it on the plane. Probably ounces versus gallons. (~100 mL vs. 1-2…

I've heard it said that plumbing issues dramatically increase with modern, water-efficient toilets. It's not hard to imagine why. Sewer usage and maintenance are at a far lower rate, so stool will settle and clog when ever smaller amounts of water are introduced.

I'm not sure this problem can be solved, assuming regular sewage as the method of disposal.

A lot of problems are also due to old systems. Ask any plumber. The plastic pipes are smooth inside. Old pipes weren’t only rough, they degrade. Cast iron sloughs off into itself. There was a kind of pipe that was used that was basically tar paper; it broke down and clogged itself (like cast iron).

A new building with new toilets should work very well. Replacing your toilet may not help if your pipes from the 60s are basically nonexistent.

> "adrenaline"

If you're not used to flying (like yourself) this might be the case. For regular flyers (like me) it's often more like taking the subway or commuting to work. Personally I always get an aisle seat, take at least two liters of water with me to combat the dehydration and let me get to work/family/whatever in the best shape I can be when I land. I always eat ahead of time or at the airport (lounges make this more reasonable) because I also know that on the other end of the flight there's baggage, a taxi, checking into the hotel, getting to dinner, etc. So figure at least two hours of hassle before a dinner or snack is possible, usually more.

Orangeburg pipe is the tar paper stuff. It's a time bomb. Not only does it break down with use it also flows (flattens with gravity/overburden pressure, bends over unsupported sections run through walls/floors, etc) over time as well, especially in a hot environment. So even if it doesn't get much use it will collapse and/or stretch and break.
