View Full Version : last night at the urinal

Ok. It is very small media... but can somebody explain what this means:
"Saves 88% more water than a one gallon urinal"
Seen in the bathroom of a local supermarket.

I often have trouble understanding what these percentages really mean. But this one sounds even more confusing. I mean, I don't know how much a one gallon urinal saves in the first place.

It all depends on what they are comparing that 1 gallon urinal to as the standard.

Current federal guidelines say that 1.0 gallons per flush is the maximum. Some use as much as five. http://www.epa.gov/WaterSense/products/urinals.html

Let's say that a standard one uses 1.5. one that uses 1.0 would save 0.5 gallons per flush. The one you saw save 88% more than than that, or 1.88*0.5 gallons, or about 0.94 gallons per flush, for a total water use of about 0.56 gallons.

If they are comparing it to one that uses 1.1 gallons, then the total would be 1.88*0.1, which would be about a pint and a half (24 ounces).

If they are comparing it to a 5 gallon one, then it's 1.88*4, which would be a savings of 7.5 gallons, which is impossible. Whenever you see a stat like that, you need to know both of the other values or it's meaningless.

I love algebra.

I wish I had said that in high school. I might have ended up first in class.

That's algebra?

Maybe if there were more urinal questions, I would have passed. I don't do well without story problems.

I was at the local sports bar, and they used hang the sports page up to read while using the urinal, now the local paper has gone to 3 days a week, so they have an LCD Screen with whatever is showing that is the "big game du jour".....very interesting use of facilities..

There are also video games that use "hands free" controls.
It's an interesting idea, but I'm not thrilled about the high-fiving afterward.

The job site I am currently working has bathroom trailers with no-flush urinals. The sign over the urinal says that each no-flush urinal saves approximately 40,000 gallons of water per urinal per annum over a typical urinal. If they are considering a 1 gallon per flush urinal that would only be 109 flushes per day. I think that's a little low. We engineers aren't on site on Sundays, but the craft people are here 24 hours a day seven days a week.

In Portugal, most toilets have two buttons on the top, one for a #1 flush, and the other for #2.

I've seen those elsewhere in Europe and have started seeing them in the US.

Other than the posts about video games or newspapers hung up by the urinal, I'm not sure I undertand what this all has to do with Small Media at Large, but I'm not going to get P.O.ed about it. :p

By the way, if I posted a very long, rambling post about the topic, would that be an example of "stream of consciousness".

I think that just qualified this thread for the Very Bad Puns forum.

I was thinking about the term " Wee engineers " . Very appropriate . :)

But how many of them would actually flush a urinal? :whistle:

Good point. I guess I was thinking about the autoflush urinals, but I haven't seen too many of those on job sites.

We had a discussion along thos lines at work one day. We decided that you can tell an engineer 'cause he washes his hands after. A machinst washes his before. And a pipefitter never washes his hands.

Sort of like the signs you might be a chemist, one of which is you wash your hands before you go to the bathroom.
