You joke, but it’s partially true.

I heard about a tall building that had its basement flooded with sewage. It turned out that the plumbers had simplified the drains. Rather than install the random turns every couple of floors, they just used a straight pipe. In effect, turds were falling 20+ floors, to smash into an inspection/access hatch. Eventually the screws sheered off, and everything emptied into the basement instead of the sewer.
