To Flush Or Not To Flush
gooman writes "Tired of arguing the same old issues like Linux vs Windows? Choose up sides in the fight over flushing vs non-flushing urinals. The L.A. Times reports on efforts to place the waterless urinal into the Uniform Plumbing Code. To quote: '...the ordinary-looking urinal is at the center of a national debate that has plumbers and water conservationists taking aim at one another.' Amazingly simple, the no-flush urinal uses gravity to force urine through a filter containing a floating layer of oily liquid which then acts as a sealant to prevent sewer odors from escaping. Each no-flush urinal is claimed to save over 24,000 gallons of water a year, but the opposition is concerned about the spread of disease. Although not mentioned in the article this technology is in use around the world. Does anyone have these fixtures installed at their place of employment? Are there any real drawbacks? Is this really a worthwhile debate or just an excuse for toilet humor?"
On my next birthday, when my wife asks me what kind of cake I want, it's going to be Urinal Cake.
It doesn't matter, urine is sterile anyway. People are just really paranoid. ... unless said person has something quite serious going on and blood is coming out, but I have a feeling that's pretty rare.
Urine is sterile when it first comes out.
But it makes a really great breeding ground for bacteria (which can colonize it from the air, or the remnants of some guy's puke in the urinal, etc.).

If it's yellow let it mellow. If it's brown flush it down.
Urine is typically quite sterile (except for the occasional malfunctioning kidney or urinary tract infection letting some bacteria through)
The problem is urine tends to have a composition that fosters the growth of bacteria as they somehow manage to get into it. In fact this is one reason urine smells, typically urine is quite odorless when leaving the body. The 'stale urine' ammonia smell you remember from bathrooms is a biproduct of the decomposition of urea by bacteria.
Incorrect. The situation is already changing. And it is going to get worse soon.
Redwood City, CA, -- smack in the middle of one of the most affluent areas in the nation -- currently has what amounts to a ban on all new construction because there's simply no more fresh water. They have already exceeded their allotment from available supplies. Los Angeles has been living on borrowed time for decades, damming up every fresh water supply in sight and draining it dry. Tulare Lake, once measuring roughly 30 by 60 miles across, is now essentially gone. It took government intervention to keep them from completely draining Mono Lake, but they're still slurping a monsterous percentage of the Colorado River. Other scattered communities throughout the continental US are noticing the rivers and lakes are drying up, and underground fresh water aquifers are also becoming harder to find and maintain.
There is a problem. And as long as the population increases, it's only going to get worse. As I see it, there are only two real long-term solutions:
I don't really give a sh*t if you have a six-figure income and can afford a $500/month water bill; the surrounding community that supports you can't sustain it. So mandatory conservation for everyone. That means 1.8 gallon or less toilets, low-flow shower heads, front-loading clothes washers, underground or drip irrigation for gardens. If you're really snazzy, you'll recapture your waste water and re-use it for the garden or the toilets -- or re-purify it yourself and take pressure off the municipal supply.
We have a nationwide power grid. Why not a nationwide water grid? Some areas of the country get flooded every year, while others suffer drought. With a national network of large pipes, we can ship water from areas that have too much to areas that don't have enough -- use the flood waters from the Midwest and East to relieve water shortages in the West, and vice-versa when the need arises.
Of course, I'm just an insane computer programmer, so what do I know?
By the way, if you want to talk about the (lack of) need for water conservation and be taken seriously, then viewing this is a mandatory prerequisite.

Why is it that the US, one of the most advanced countries in the world cannot get their $#!^ together, pun intended :-) when it comes to plumbing issues that most of the rest of the world seems to have solved years ago?
Because it seems like if it doesn't (a) get somebody re-elected and/or (b) make somebody a profit, it usually won't get done.
During WWII, Winston Churchill put it best. To paraphrase: The Americans, when all other options have been exhausted, will do the right thing.
Government's idea of a balanced budget: take money from the right pocket to balance...oh who am I kidding?
IIRC the high pressure public toilets use less water but are not used in homes because they require higher capacity source pipes for a powerful burst and because they are noisy.
Snowden and Manning are heroes.
Sorry, but you have no idea what you're talking about. The only place you'll see the old, high-flow toilets are in older houses. You can't even buy the things anymore, not since 1992. 1.6 gpf toilets are now standard everywhere in the US. There was early resistance to them because, as another poster pointed out, early models did not work well, and in reaction some people went so far as to import high-flush models from Canada. No one bothers anymore unless they're atavistic; new low-flush toilets work just fine.
And the brethren went away edified.
Well then, it's not all that similar then, because the one described in the summary has a "floating layer of oily liquid". It sounds like the US Navy ships' urinals that you're describing let the urine sit there in contact with the open air for indefinite period of time, whereas in these toilets, the oily liquid serves as a barrier between the urine and the air. Presumably this prevents certain volatile (meaning prone to evaporation, as opposed to unpredictable) chemicals from evaporating and smelling up the place.
The point being, although they may be similar, it seems like the oily liquid is a key difference.
These waterless urinals were installed about a year ago in my community college here in Southern California and I hate them. Yes, they do conserve a lot of water, but that oily liqued does not seem to keep the odor out, it still stinks!
I don't know about your experience, but are you aware that while urine is considered "icky", it is, indeed sterile, and even mildly sterilizing? The smell is ammonia, which is what the body gets rid of with urine. It's a different thing about feces - they can indeed cause the spread of disease, and they are the hygenical reason for plumbing.

Ack!
i am a plumber here in seattle, some comrades in the trade installed these waterless urinals in the Smith tower here, all though the bldg. well it was not long after that the complaints of the smellls started coming. so i guess if you want to save water you can live with the smell. from a professional point of view i think that they are unsanitary. that flush of water rinses the porcilen of the urine. i know that 99% of the readers here have never had to remove the drain piping from a urinal from behind a wall but its amazing how much scale buils up inside the pipes from a urinal(really one of my least favorite jobs best left to the apptrentice). without water this scale will become even thicker faster causing a failer of the drain. so it ends up costing the customer more in the long run. and finally for those who think i am overpaid , whats it worth to you to stick your hands in a bucket of sh#&....
I'm amazed you've been modded so positively. The parent was not making a cut on New Orleans - I believe the rhetorical device being employed is known by some as satire. New Orleans was a tragedy, and yes, Californians can do more. But problems concerning water span governmental boundaries - municipally, federally, internationally.
California should do more to dig itself out of its own mess, but that doesn't mean that waterless urinals won't help - and that's the point of the discussion, is it not?
Actually you're wrong, I am a mechanical engineer and design plumbing systems, the larger the pipe, the better, sanitary pipes are not under pressure, they are gravity. Code minimum is 3" for all water closets in every town I've worked for, older water closet installations usually have 4", which is what I always call for.
I'm not not licking toads.
