WaterSense Meets EPA CriteriaThe Tresa Collection, along with many other Brizo designs, improves water efficiency through use of an aerator. The result is a faucet that delivers 1.5 gallons of water per minute — 31% less than a typical lavatory faucet. Tresa is also a WaterSense labeled product certified by a third party to meet U.S. Environmental Protection Agency requirements.
