Web Case Study-Odor-Reducing and Water-Conserving Urinals Installed at Rose Bowl
All of the trough-type urinals in the men's restrooms at the Rose Bowl have been replaced by 259 Falcon Waterfree urinals. With the water savings from the Rose Bowl event combined with the savings from UCLA's home football games, concerts, Fourth of July celebrations and other events, the total water conserved in a year from using the waterfree urinals comes to more than one million gallons-a substantial amount for a region where the fresh water supply is struggling to keep up with demand.
Waterfree urinals look like standard urinal fixtures but have no incoming water line and don't use any water. Instead, a replaceable, biodegradable cartridge at the base of the urinal acts as a funnel. Liquid waste passes through the cartridge, penetrating through a lighter-than-water liquid sealant that closes after the urine has passed. Odors are eliminated, since urine is trapped below the sealant and the chemical reaction between water and urine that creates the odor associated with flush urinals is eliminated.
