40,000

The waterless urinals claim to save an average of 40,000 gallons of fresh water per urinal per year.

Now, if each urinal flush is 1 gallon (which seems to be the maximum per flush on the American Standard website urinals) that's 40,000 flushes a year, or about 109.5 flushes per day or 4.6 flushes per hour in a 24 hour period 7 days a week. In an office building open only five days a week for 12 hours a day it's about 12.8 flushes per hour.

That's a helluva lot of water. But how do you flush a waterless urinal?

You don't flush waterless urinals. You just go.

That's more than 5 flushes per minute ... That means that every 12 seconds someone in an office is flushing a toilet...

Uh, it's more like one flush every five or twelve minutes per urinal, depending on which building you're looking at.

To have a urinal flush every twelve seconds is to assume that there are 25 urinals in the building for the ones that flush every five minutes or 60 urinals for the one that has a flush every twelve minutes.

So ... if they don't flush, do they get nasty? *shudder*

They're cleaned every morning, but by the afternoon, there's an... odor.

Hey, Leno said tonight that there was a budget agreement or something in California. Is that good for you?

Jazz said...

You just go and it all stays there on the sides of the urinal? That's just nasty.

Geewits -- A budget was signed, but there are still threats of lay-offs and until our new contract gets ratified we'll be furloughed twice a month. And then we get furloughed once a month until 2010. It's a marginal victory.

Jazz -- Well, it's porcelain, so the pee, mostly, slides down the sides, but sometimes the smell does get a bit rank.
