In a city that has long had its battles with water conservation, this is just one more way to save lots and lots and lots of water. So just how did this "vitreous china urinal" clear all of the hurdles? Well, by making a product that outperformed the other urinals in operation, odor management, durability and waste build-up. If the city was going to approve a system that might make some people a little queasy, they had to find something that wouldn't leave a mess for anyone to have to deal with.
The H2Zero system doesn't use a oil-based seal, like most waterless urinals, but instead uses a cartridge with a Bio Fresh deodorizing block inside that is activated upon use. The system allows urine to pass through freely but also acts as an airtight valve so the user doesn't have any lingering scents. As the urine flows through the cartridge, it heats up the deodorizing block and lets out a slight lemon scent. The cartridge lasts roughly 10,000 uses and then must be replaced. Plus, their larger size is "ideal" for retrofits because it will cover over just about any spot you used to have from that old water-hogging urinal.
Caroma expects that their system will save the city millions of gallons of water each year just by replacing common urinals with their H2Zero waterless urinals. The Caroma is also a maker of the Dual Flush Toilet. Heck, next thing we know the city will be promoting "if it's yellow let it mellow..." with little signs on every bathroom stall. :Caroma
