Water-Free Urinals

Denver is doing it’s part to conserve water with four water-free urinals. You heard it correctly, water-free. The four have been installed in one of the 14 public restrooms in the City and County Building.
The urinals will save close to 40,000 gallons of water a year each.
How they work:
A cartridge at the bottom is filled with liquid to stifle odors. The replaceable cartridge, which is connected to a drainpipe, is designed to handle about 7,000 uses.
The liquid inside the cartridge “provides an airtight barrier between urine and the restroom to prevent odors from escaping the drain, but allows urine to pass through because it is lighter than water,” says the manufacturer, Falcon WaterFree Technologies, who donated two and the city bought the other pair.
So far, users a applauding the new toilets.
Cost: $238 each, the same as standard urinals.
The standard urinals in the other restrooms in the City and County Building use about 3.5 gallons of water per flush.
