I certainly was surprised to find that they kept pee troughs in the restrooms.
Troughs are an efficient use of space and water, and keep the lines moving faster. I never have understood the objection.
Are they an efficient use of water? Water literally flows non-stop. I would imagine the low flow urinals would be better - they don't run when people aren't using them.
Water usage is very low.
Typical flow rates are far lower than 1gpm.
I've turned the water on and off, and it takes a long time for the trickle of water to reach the drain.
That flow rate is enough to move everything along, and not spray water all over the place.
(Turning them on too high does make a mess.)
Let's just say 1 gallon per minute, to make calculation easy.
There are six pee-wall men's rooms, each with four pee walls.
That's 24 gallons per minute, if they're all running.
Call a game a six-hour event, just because.
That's 144 gallons.
Piffle.
The EPA mandates a maximum of 1 gallon per flush on commercial urinals, but it can be less.
A quick search shows units as low as zero and some at one pint (0.125 gpf)
Rice is all about LEED certification - and the LEED standard is less than or equal to 1.1 gpf.
For simplicity, let's just say 1 gallon per flush.
Our average crowd has been about 5,000.
For ease of calculation, let's assume that half are male.
For ease of calculation, let's assume that the males pee once per game.
For ease of calculation, let's assume they flush every time.
That's 2,500 gallons.
If they used the pint-per-flush unit, that would divide by 8.
312.5 gallons.
Over twice as much as the pee walls.
The U.S. Geological Survey estimates that a single person uses 80-100 gallons of water per day.
By going to a game and using a pee wall, there is probably a net savings of water for the community.
The urinals would require a fair amount of plumbing (I have the drawings here somewhere for the lower-west rest room mods), and a fair amount of maintenance.
The pee walls get a coat of paint, and most years they don't get that.
You want to save money and water - stick with pee walls.
Can we hire someone to paint murals of the other AAC campuses on the pee walls, just for our entertainment?
(I know the answer to that is "no", but I can dream my diabolical dreams, can't I?)
