Water Savings Learn More
Eight of the 34 products detailed in the 2012 “The Efficiency Boom” report have potential water savings. Of the eight, residential clothes washer standards would provide the largest water savings; dishwashers, faucets, toilets, urinals, automatic commercial icemakers, commercial clothes washers, and pre-rinse spray valves would make up the rest. For plumbing products, national standards exist, but federal preemption of state standards has expired, so updates may be adopted at either the state or national level.
On a cumulative basis, water savings due to new and updated national standards from products sold through 2035 would amount to 5.5 trillion gallons, a volume larger than the amount of water that flows over Niagara Falls over the course of 2.5 months.
