Benefits of Flushless Urinals

In areas with population density and a water problem, such as California or Nevada, flushless urinals may prove to be a necessity. Studies have shown that the per capita water use could be decreased by 33 percent. This means that where 185 gallons of water are used per person per day, flushless urinals could lower it to 123 gallons.

The technology sounds remarkably simple. While traditional urinals use about three liters per flush, a flushless urinal uses none and requires no flushing mechanism. These devices use a pore-free glaze or surface coating that repels liquid. Urine simply flows into a siphon and through a liquid barrier with a density lighter than water. The urine passes through the barrier, taking any odor with it.

Since the gel-like surface has no pores, no urine or bacteria can get in to stain or smell. This also reduces the water and time used in cleaning the devices. Overpowering, dangerous and odorous chemicals that are used to maintain urinals could be a thing of the past. In large facilities such as universities and office buildings, studies calculate that savings could range between a meager $800 to an impressive $40,000. Either way, it makes good economic and environmental sense.

The Ugly Side of Urinals
Down sides are expressed with certain models. Some have splash back problems, like all urinals, that tend to make up for the odor seal in the siphon. And, since it is a urinal, occasional cleaning is necessary. Managers may try to save by not cleaning them at all or cleaning improperly. Both can give unhygienic results. Nonetheless, for a greener option, the flushless urinal has its advantages.
