Urinals can account for a significant portion of indoor water usage in commercial and institutional settings. A typical office building could reduce its water use from old, inefficient urinals by 26,000 gallons per year or more. While the current federal standard for commercial urinals is 1.0 gallon per flush (gpf), some older urinals use as much as five times that amount!
Replacing just one older, inefficient urinal that uses 1.5 gpf with a WaterSense labeled model could save a facility more than 4,600 gallons of water per year. Nationwide, if all older, inefficient urinals were replaced, we could save nearly 36 billion gallons annually. That's equal to the amount of water that flows over Niagara Falls in 21 hours!
