How do sewers in skyscrapers work?

When someone on the top floor flushes, does their poop plummet hundreds of feet down a pipe? And how do they make sure that a blockage on a bottom floor doesn’t make the building flood with poop water?

I assume you’d have a ‘main stack’ as in a bigger pipe that runs up the whole building, and then the smaller pipes that would branch out to toilets, showers, etc from there. So once the waste got to main stack then yes it would just fall all the way down.

As for the other question, there are usually access points to reach pipes. So once a plumber determined the location of the clog they’d just fix it from the nearest available one.
