I remember handing out questionnaires for my senior project back in my undergrad days.  The questionnaire mostly dealt with water use on campus.

One of the questions was about waterless urinals.  Many people were opposed to them, simply because of the hygiene issue.  Since I had never used one, I also had concerns about smell and cleanliness.

Well, I can finally say that odor is not a problem.  There is a waterfree urinal installed in one of the restrooms at the location where I am taking a class this week.

I didn’t detect any odor before or after using the toilet.  Although I did smell some asparagas during use.   Haha, or the string beans from Whole Foods.

Apparently there is some sort of filter that not only traps the odor, but filters the pee, before going down the drain.

Think about it though, at 1 gallon per flush (the standard for most urinals today), you could be saving a lot of water and money!

Also, since it doesn’t flush, I guess this is literally just a “urine hole” then??!?  You know as opposed to urinal.
