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?"
There are actually a number of simple implementations that I have been absolutely surprised to not see in the US. For instance, in other places I have traveled around the world, dual flush toilets with "light" and "heavy" flush modes are available everywhere except in the most undeveloped third world countries. However, here in the US, particularly in water restricted areas you see standard high-flow toilets. Granted many "low flow" toilets such as the ones available in many areas of California are not so great if you have a fruit/vegetable intensive diet, but for some reason the toilets available in the US simply don't have the "power" that other more advanced designs have elsewhere in the world and I am not talking about the advanced technology toilets that they have in Japan either. Those are actually kinda scary because of all their automation and such, but simple things like pressure assist can make for very effective low water use designs.
:-) when it comes to plumbing issues that most of the rest of the world seems to have solved years ago?
Why is it that the US, one of the most advanced countries in the world cannot get their $#!^ together, pun intended

the ultimate pissing contest. :P
We have a no-flush urinal in the bathroom where I live
The disadvantages are that you have to change the filter every, like 3,000, "non flushes". The filters are expensive and I'm sure they're slightly wasteful. If you don't have a new one, the entire urinal stops working and lovely pee just accumulates inside the urinal. And that stinks.
What would be nice would be a hybrid - it's a no-water system until the filter, "craps" out, and then you have the regular way of doing things, as a backup.
Saying all that, it's proven to save us lots of water and keep our incredibly delicate plumbing working well.

Pfft... seriously...
I will just be happy when they invent no splash urinals...is it really that difficult??
I sure hope they dont use these things in restaurants that serve asparagus.
"Is this really a worthwhile debate or just an excuse for toilet humor?"
/., I'm gunning for the latter. I offer as evidence any comment that gets modded "Funny", including this one.
Given that this story was submitted to
That green slime had it coming.
This picture shows that flush / no-flush is not the only debate over urinals, at least in Korea.
Put identity in the browser.
I work as a government electronics contractor onboard U.S. Navy ships....some of the smaller ones have a similar urinal installed. It just collects urine until a certain amount has been collected (about 2 pisses or one really long one) and a level switch trips a vacuum suction device that sucks it away. The only drawback is that the urine that naturally coats the urinal walls and drain STINKS as it ages and never gets a water wash-down. It's nasty, but that's what you get when you piss in a hole and let it sit. I think they used to call it an outhouse back in the day.

On my next birthday, when my wife asks me what kind of cake I want, it's going to be Urinal Cake.
Isn't a no-flush urinal called a tree? Why not simply avoid the sewer system and start installing shrubberies in all men's rooms :)
Here's to losing my Karma Bonus again....
That's an attitude I always find refreshing. Let's not worry about making small improvements and only go for the big ones. After all, slow and steady loses the race. There's no point in making things better if we're not making them a LOT better.
ANP, in Bar Harbor, has these at the summit of Cadillac Mountain. One of the major attractions at ANP, these urinals get a lot of use. No noticeable smell and the rangers seemed happy about the reduced maintenance.
Yes, I went to a national park and asked about the urinals.
It makes them oily and hard to light.
Seeing as how urine is fairly sterile, I just pee in the sink. no splashback, and it all gets washed down when i wash my hands. I learned about this environmentally friendly tip from Adam Carolla.

One of our newest buildings on campus (1998) is the EESAT (Environmental Education, Science and Technology) Building. There is a picture of the building at http://www.ias.unt.edu/about/. It is generally a favorite building on campus to have classes in, with a giant earth population clock, all native plants landscape the facility, and other conservation and science exhibits exist in and around the building.
The mens, can't speak to the womens, have urinals that are the flushless type described and there is a plaque above them indicating that they save water and trap odors. However the contractor went ahead a outfit the urinals with a water pipe in case they didn't work out. It stops short where an L shaped pipe would normally connect to a standard handle flushed or motion activated unit.
They have been there for several years without complaints, and they don't smell, so in this instance they are a success.
Sorry to break it to you bro, but this has nothing to do with what is available. The only thing that will mandate new methodology is political mandates. The only problem is no politition is going to back a bill that will raise contruction prices and help them lose all there campaign dollors from big developers. I'm an architect and I've seen it over and over again where a product will come out that will help either the environment or energy conservation. A contractor will look at it and go " what the heeelll is that I can install ya ten american standards that I gots sitt'n in back it will save you $$$$$$$$$$$$" ofcourse the developer doesn't care these are being sold to deseperate homeowners no.349835439
We had one installed at work - then ripped out and replaced with an old-fashioned water variant. It kept on blocking up. We asked why, and the answer came back that people were pissing in it too often.
:v)
Well sucks to that idea. Out it went.

Let me say one thing- No Flush Urinals stink to high hell! It's incredible. I work in an ~20 million dollar building on the University of California, Santa Cruz campus (Engineering 2- for those who know UCSC) which was completely 2 years ago, and it has only no flush urinals. They're nasty. Yes they save water, and that's a good thing, but to be lauded as new tech! Give me a break. Imagine that design meeting? "I've got an idea! No water in urinals!! We'll save water and then spin some horse#$%! about how they are odor free!!!" Thanks Guys!

Subject: RE: PUR Hello J.R., Gee-Whiz, I must admit that I read your e-mail with some skepticism. Upon further reflection I came to the conclusion that you could indeed run human urine through our filters. If you do this it could very well hasten your way to death, but you can filter urine. We don't normally test urine or the body's by-products associated with it. Drinking urine is a bit out of the main stream, if you'll pardon the pun. The filter may have some effect on the potency of the ammonia. If you're in an emergency situation with out water, drinking urine will only make your day worse. The ammonia in urine isn't what's going to ruin an already pisser of a day, its the salts. By constantly reintroducing those salts into your system, you are increasing the amount of salt in your system, and decreasing the amount of usable fluids. This salt will draw water from other tissues in your body, as will your kidneys. Your kidneys need the extra water to flush the salts out. It's a viscous circle. As your kidneys are shutting down, the poisons in your body will increase; thereby playing havoc with your heart. The lack of electrolytes in your in your brain can cause the synapses to misfire eventually causing you to get delirious and run screaming into the desert waving your hands over your head chasing Elvis. All levity aside, I am not a physician. However I do understand our products and have a thorough understanding of human physiology. My recommendation is not to do it. Carry a bladder of water in your trunk. Being prepared is the best way to keep from having to drink pee. Mahalo, Mark -----Original Message----- From: Willett, J.R.

Not only have you saved us from what could have been a disasterous science experiment, but you have provided a tremendous amount of amusement to several college students with perhaps too much time on their hands to wonder about such things.

Your skills in customer service extend even to answering the questions I did not ask.

If a doctor contradicts me then ignore everything I say here.
Kidneys are wonderful microfilters and normally don't let bacteria through. On the other hand there are kidney diseases that let things through that shouldn't be there. The vet monitored our late cat's kidney disease by checking whether bacteria were showing up in her urine.
Then there are bladder infections.
Normally though urine is considered the most sterile of body fluids.
It is, for the most part. But it's nutrient rich and a great source of food for the bacteria living in the bathroom environment. By peeing on the floor, for example, you're not really adding bacteria to the environment, but you're feeding the ones that are already there.
If it's yellow let it mellow. If it's brown flush it down.

Intentional or not, that's a horrible pun.
I used to have a roommate that often took showers that lasted in excess of an hour. The apartment we lived in only had one bathroom, and there were no convenient bushes outside either. He always locked the door when he was in there too. On more than one occasion I woke up having to go really bad, and he was in the shower with no indication of how long he would be. I usually ended up peeing in the kitchen sink on those occasions.
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.
I for one am not in the habit of rubbing my genitals on the urinal.
You are so boring that when I see you my feet go to sleep.
This is just going to add to the problems the sewer systems face in heavily commercial districts due to the use of low-flow toilets.
In residential areas there are not as many problems with clogged sewer lines. Laundry machines, showers, dishwashers - these all add lots of water to the sanitary sewer system and keep the percentage of solids low.
Commercial districts, OTOH, are having increasingly large problems with plugged sewer lines. Low-flow toilets are pushing (or failing to push as the case may be) sanitary lines over the edge. The point is being reached where there just isn't enough water introduced into the lines to move the, um, solids.
The only solution is either decreasing the solids percentage in the system by increasing water use, or increasing the pitch at which sanitary lines are laid. You can only increase the pitch so much, though, before you run out of drop and need to install lift stations (bringing their own set of environmental costs.)
I dub thee... Sir Phobos, Knight of Mars, Beater of Ass.
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.
Einstein, you might have noticed that the article appeared in the Los Angeles Times. There is a huge water problem throughout pretty much the entire state of California. The San Joaquin and its tributaries have been totally tapped out by Northern California, the excess of which is sent down a concrete-lined artificial river hundreds of miles long to Los Angeles and the rest of southern California.
There is basically no more water available in California, yet water use continues to grow. San Francisco is seriously considering building a desalination plant for its water system, which supplies the peninsula and much of the south and east bay including parts of San Jose. SoCal is already way beyond sustainable water usage.
The only way to mitigate water usage growth is through conservation.
With great power comes great fan noise.
Ecological sanitation will be the only choice available to countries like India and China who are water-scarce. There is no way that all 2.5 billion+ people will be able to use water-based flush sanitation. Yet sanitation must be safe, clean, and easy to use. Ecological sanitation (or ecosan) is based on dry, urine-seperating toilets. No water is required, no major infrastructure, and all urine and faeces is safely composted without any need for electricity. The composted urine and faeces can be safely used on cropland for fertilizer. Currently, over two million Chinese use urine-seperating toilets in the south of China, and there is a major urban pilot project in Inner Mongolia. Additionally, some African countries are committing to 100% use of ecosan. No water, low-tech, no smell and no flies - plus fertilizer? No question of why, merely when and how!
sig? what sig? i didn't see any sig...
The best thing about being a man is that the whole world is your urinal.

I might know what I'm talkin' about, but then again, this is Slashdot...
I know this is just anecdotal story from living in my dorm but I'd figure i should share. 25 guys shared one bathroom which had three toilets (and two urinals). One toilet stall was for handicapped people so it was nice, large and comfortable. This poor toilet saw the waste of ever gentlemen every day and invariably it would clog during the weekend, every weekend. Just didn't have the power to deal. RUM+COKE
It depends on where you live. I recall reading that in the midwest, something like 60-70% of water usage is on lawn watering. In wetter climates I believe it's more like 40%. [pdf]http://www.energyrating.gov.au/library/pubs/w a-wateruse.pdf is a relevant study done in western Australia; page 32 has a nice pie chart that shows 51% of water is used on lawns, and 8% on toilets. In non-pdf land, Concord, California says their breakdown is 40% grass / 7% toilets (http://www.ci.concord.ca.us/living/recycle/env-wa ter-use.htm
These are both from reasonably rainy areas. So yes, your gut feeling is very right.
Let the market decide the price of water, and then let anyone use as much as they choose to pay for accordingly. I mean, shouldn't it be telling us something when the government has to regulate our tiolets in the name of good causes?
I grew up in Michigan and we called them trees and if some one hasn't patented them they will any day now. I'm quite sure no one has patented trees for the express use as a traget for dogs and the odd hunter or wino.
If you take a long enough view, you will see these problems work themselves out. Your goal is not to find the solution. It's to survive it. If you are in an area that's resource poor, move.
The fact that so many otherwise smart people have trouble with this simple answer defies reason.
If you live in a country with a repressive regime, escape. If the drought has been going on for more than five years, it's a climate change. Move. If your city is below sea level, you should not live there. Move. If your climate is inhospitable to human life, leave it for the creatures that like it and move. Is your region so crowded with other people that life there is unsustainable? Get OUT.
This is not so complicated. You are blessed with the power of locomotion. Use it.

Fresh cheap water _IS_ Plentiful in most of the United States, You decided to use for your example the reason why parent poster used the word "Most" and not "All"
"waters from the Midwest and East to relieve water shortages in the West, and vice-versa when the need arises."
To this I say, Fuck You. There never will be a Visa-Versa, You would just leech off of it entirely and never find a solution to your own damn problem. it was entirely the prerogative of the population in west to build a paradise in a desert, it was entirely their decision to drain the Colorado for water intensive farming, to put a swimming pool in every backyard of vast stretches of Arizona suburb complete with matching green grass. status symbol accessory.
I live next to the great lakes, cheap water is more than plentiful, and you almost never see farmers ever have to use (let alone own) irrigation equipment, our farmers farm In an area perfectly suited for it, and our population drinks the same plentiful waters.
Oh dear, California cannot provide for its population, Boo Hoo, do yourself a favor an cry a friggin river.
I'm not saying water conservation isn't important, Though I would say water pollution is a bigger problem that needs immediate attention. California is not the rule. California and the surrounding states are the exception, You built a metropolis in a desert, and you reap what you sow, Enjoy!

Visit Palm Springs or Las Vegas if you want to witness the ultimate in water waste. Hundreds of golf courses being watered daily in the hottest and driest climate in the United States. Perhaps just banning desert golf courses would solve a lot of the problems.
First, lots of cities in the US are changing their building codes to get rid of "low flush" after having them for years. Low flush toilets actually waste water because they frequently don't carry away all the waste on the first or second flush, so people end up flushing them repeatedly. After five flushes on a low flush, you've wasted like 3 times the water to accomplish what a regular toilet would have done in a single flush.
As far as "no flush" oil based systems, I've actually used one and I was disgusted by the smell. The state of South Carolina has (or had during the early-mid 90s) a "zero effluent" rest area on I-26. It used a mineral oil based system. They had big signs explaining how it worked and how it was so evironmentally beneficial etc etc etc. The problem is that it smelt like the monkey house at the zoo on a bad day. And I don't mean like a normal rest stop smells, but like a normal rest stop x12. I lived in the Carolinas back then and I frequently traveled that interstate, so I learned to "hold it" and skip that particual rest area and pay $.85 to buy a cup of coffee at McDonalds so I could use their regular bathroom. The smell is a dead give-away of bacterial growth. There is *NO WAY* an oil based no-flush system could ever be sanitary.
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!
A few of the buildings at UNC Chapel Hill use no-flush urinals. They seem to work pretty well, and do what they are advertised to do--except for one problem. Things splatter. Everything doesn't go right down the drain--the sides of the urinal catch the splatter, which then isn't washed away. And so it starts to stink. It's nothing so terrible you can't go in the bathroom, but it definitely isn't the perfect solution they advertise, either.
Perhaps if they can solve the splatter problem...
The vast majority in the UK just have a large tank high up on the wall, and a timer flushes them all every hour or so. They normally don't smell particularly (except the infamous "public toilets" that only the very desperate use) and I guess this saves a lot of water over ones that flushed every time?
Don't speak too soon. I live in a part of the world where to get even moderately palatable water we have to dig borewells which go 150 ft or more in depth.
When it gets this bad, you don't want any new high rises in your neighbourhood because in a single high rise there could be 50+ families sucking the little water that is remaining at such speeds that entire neighbourhoods go dry. The situation is so bad in some parts around here that there is ABSOLUTELY NO water even at depths of 300 ft or more.
When it gets this bad, you also don't want your rich neighbours to suck out all the water leaving the rest of the community completely dry.
There are people rich enough in these parts to have swimming pools even as people on the same street have to lug water from miles away.
Please don't live in this utopia where economic pressures somehow lead to a just and fair sharing of natural resources. It has never happenned and it may never will.
We have legislation now which prevents to a small extent the complete wastage of water. But the situation may deteriorate to the point where the state may have to ration out the water for each family. Sometimes desperate measures are needed to prevent total collapse of the system - sometimes the state just has to step in to ensure that all citizens have enough; socialism is not all bad sometimes.
To correctly wash your hands: do to the towel dispenser and unroll enough towel to dry your hands when done - leave the towel hanging. (if the towel is not on a roll you skip this step). Turn the water on, and adjust to the temperature you like. Wet hands. put soap on hands. Lather for at least 30 seconds, making sure to get the spaces between fingers, and under nails (as best you can). Rinse hands. Remove towel and dry hands. Use towel to turn off faucet. Throw towel away. Leave bathroom by push on door with your shoulder (the doors are supposed to open out, if not use the towel to open door, then your foot holds the door open while you throw the towel at the can).
This is easier than it sounds. I always do it this way, but mostly because I like to confuse other people when they see me do it.
We have waterless urinals at work (overall they are very common in southern california), and yes they smell because the urine builds up on the sides and stinks.
I spoke to the janitor once about them, because they seemed like they would be very hard to clean... and he said that they were very difficult and very unpleasant to clean. He also said that they break all of the time and the oil cartridges need to be replaced every few months (even though the manufacturer claims otherwise) or the urinals will overflow with a very nasty mixture of urine and oil.... and the cartridges are very expensive.
There are 10 types of people in this world, those who can count in binary and those who can't.
If your toilet is ever in danger of overflowing and you're quick enough, turn the water supply to the toilet off. The reason it's overflowing is because water is still flowing to the toilet bowl but isn't being allowed to exit. Cut off the water supply (via the turn knob) and it won't overflow, then you can use a plunger at your leisure instead of frantically trying to catch it before it becomes a big mess. I can't tell you how many times this has saved me.
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#&....
Seems that these are a good idea, but the execution is a bit poor. We have them at work, but the shape of the urinals is wrong. You walk out of the bathroom with a significant amount of "splash back" damage. Because of this most guys use the regular toilets.. I bet that really drives up the water bill.
Here in Las Vegas, the golf courses are heavily restricted in water use. A few have wells that are supported by the perenial yield in the groundwater basin, the rest are using reclaimed water (treated wastewater used for irrigation), As for the casinos here that so many wave their finger at, They use grey water for the water features (Bellagio and Mirage fountains) and the only significant consumptive use is the water lost to evaporation in the air conditioning systems. The water used for toilets and showers is treated and returned to the Colorado River and a return flow credit is recieved. The single largest use of water in Vegas is single family home turf irrigation.
A friend of mine took his girlfriend to the Virgin Islands and surrounding area (he worked for the airlines). They were walking down the beach and he went to go sit on a rock and apparently got stuck by a sea urchin in his butt.
He said he was in such pain he couldn't move. He knew that amonia would help relieve the pain so he begged and begged and begged his girlfriend to pee on his butt. She eventually did and he said it was an instant relief.
Kinda kinky, eh? ha ha ha

Refill the tank with water you've used to wash your hands with. After all, you don't need 100% clean water to flush down your waste, and you're going to wash your hands anyway after you use the toilet. (You do wash your hands after using the toilet, don't you?)
The Japanese have had toilets for a while now with a spigot on the top of the tank. When you flush the toilet, clean water comes out of the spigot (with which you can wash your hands) and drains into the tank. Check out the picture here.
Any sufficiently unpopular but cohesive argument is indistinguishable from trolling.
