As the men here know, when you would go to a public men’s bathroom in a place like a sports stadium that it used to be standard practice to have to use a trough to pee in to. Your choices were either the trough or waiting for a stall to open up.
Newer stadiums have individual urinals exclusively. I have been told that this is because current plumbing codes require them.
My question is: what was the reason that troughs were banned? Do they use more water than individual urinals? Are urinals more sanitary? Is it some combination of the two.
Here in L.A., you can still go to an older stadium, such as Dodger Stadium or the Memorial Coliseum and find the older fixtures, but if a stadium performs major renovations on its restrooms, such as the Rose Bowl, individual urinals are put in.
