What do you think of waterless or no-flush urinals?

wow, this is very interesting, cianoy! Thank you for the excellent explanation! I was wondering though, do you knw how they keep teh sealant liquid from draining out along with the water? I am very confused about this.

good post cianoy!!! its very informative, helps me a lot. because i see a lot of them here in our place on nearby roads for emergency peeing of most men. what i felt is that it is so unsanitary since i didnt see any water used in it, now that i know how it works its kinda relieved me...truly what we dont know fear us or worry us. yeah that is excellent alternative for conventional toilet we are using to save water as long as we maintain it also to avoid foul smell... thanks for the post.

Now if they could do something for the ladies so that they do not use as much water as they do. I think that if you do make one for the ladies then they will wash their hands more and minimize the saved water. Or they might even use more water washing than a flush would use.

Hello, Your description as to how waterless urinals work is essentially correct. Although different manufacturers produce slightly different models (meaning some details do vary from one product to another), your information is fundamentally accurate. However, I would like to address the odor issue referenced. Our experience has been that odor problems associated with waterless urinals are unrelated to the urinal system and that they are actually caused by improper unit maintenance and cleaning, which can be easily rectified. Generally, waterless urinals are cleaned in the same way as conventional urinals. Typically, a mild, properly diluted cleaner or disinfectant is misted onto the surface of the waterless urinal or onto a cleaning cloth; the area is then wiped clean. Since waterless urinals are essentially dry, they actually tend to have fewer odor issues than traditional fixtures. This is because a lack of moisture inhibits the growth of bacteria- and it is bacteria that cause many of the odor problems associated with urinals. In fact, studies have shown that no-flush urinals have about the same-- and even less-- odor than conventional urinals. Odors can also develop if the sealing liquid in the cartridge needs to be refilled. However, correcting this involves just pouring a bit more liquid into the cartridge which takes about 10 seconds. But overall, whether they are waterless or conventional, when urinals experience odor problems, it is usually because they have not been maintained properly and that is as easy as adding the sealing liquid into the trap. This is why we ask our distributors to always make sure that their customers are thoroughly trained regarding how to clean and maintain their new waterless urinal system.
