EPA WaterSense Label Enters Commercial Building Market

The U.S. Environmental Protection Agency (EPA) has announced its WaterSense specification for flushing urinals. In order to meet Water-Sense criteria, urinals must use 0.5 gallons of water per flush (1.9 lpf) or less. Urinals must also meet performance requirements, guar-anteeing that they work at least as well as their conventional counterparts. Of the roughly 12 million urinals in the U.S., nearly 8 million are older, inefficient models that exceed the 1-gallon-per-flush (3.8-lpf) federal standard. EPA’s estimates indicate that WaterSense urinals will save roughly 4,000 gallons of water (15,000 l) annually per unit installed.
