tradeoffs — or at least that used to be the case. For years, a common criticism of waterfree urinals was the buildup of drainline sediment that created clogs — in addition to the odor caused by the waterfree feature if not maintained correctly. These issues left the maintenance department and end users with a less- than-pleasant restroom experience. However, today's innovations, such as the hybrid urinal, combine a multi- patented urinal cartridge with Jetrinse Solution Technology, that keep urinals and drainlines clean, hygienic, odor- free and clog-free. There's no need for maintenance personnel to manually clean or rinse the housing and drainline as the technology automatically purges the housing and pipes, rinsing them thoroughly to prevent the buildup of sediment every 72 hours. Now, not only do waterfree urinals serve as the most sustainable approach to water conser- vation in the restroom, but also one of the most hygienic and user-friendly. DON'T FORGET ABOUT FAUCETS Faucets play a significant role in water conservation, too. Accounting for more than 1 trillion gallons of water us- age per year across the United States, faucets have long been a source of excessive water consumption. Manual faucets not only contribute to excessive flow rates, but also increase the spread of germs and bacteria. The introduction of automatic sensor faucets has drastically reduced water usage and increased hand hygiene in commercial applications. The regulatory standard flow rate for commercial faucets in public restrooms is .5 gpm. Although WaterSense certi- fications do not apply to commercial faucets, the current .5 gpm flow rate is less than half of the 1.2 gpm flow rate for private and residential applications that WaterSense mandates. For LEED v4 and CALGreen compliant sites, .35 gpm faucets are required. Commercial restroom fixtures certainly can't solve the water conser- vation crisis on their own. But through recent innovations in reduced flush- ometers and faucet flow rates — along with the removal of water from urinals altogether — restroom manufactur- ers are taking the lead in reducing the water footprint.
