a better goal for urinal design is water reduction. i.e. urinals that use no water
Don’t get me started on those “zero water” urinals. They start to stink and accumulate all kinds of nasty in a matter of weeks. There’s a reason we flush all of that stuff down the toilet and into the sewers.
They have them in all the McDonald’s around here and I’ve never noticed any difference in smell. There is a sticker near the urinal saying they save tens of thousands of litres of drinking water per year which I can believe. I think the system has some kind of valve and siphon to prevent smells.
