U.S. Environmental Protection Agency (EPA) Announced Intent to Revise High-Efficiency Lavatory Faucet Specification

The U.S. Environmental Protection Agency (EPA) today announced its intent to revise its High-Efficiency Lavatory Faucet Specification for residential faucets and faucet accessories to earn the WaterSense® label. EPA is reevaluating the scope of its specification to consider adding public lavatory faucets, kitchen faucets, metering faucets, and their respective faucet accessories. EPA is also reevaluating the specification’s water efficiency criteria, including maximum flow rate requirements, to address recent changes in the plumbing marketplace and standards for faucets and increase the water savings achieved by WaterSense labeled faucets and faucet accessories.

With this announcement, EPA is releasing a Notice of Intent (NOI) that describes the revisions it is considering to the scope and criteria of the WaterSense labeled faucets specification. EPA is seeking feedback from interested parties on the potential revisions discussed in the NOI by April 26, 2024.

On Thursday, March 28, 2024, from 2:00 p.m. to 4:00 p.m. Eastern, EPA will host a webinar to discuss the NOI and provide an opportunity for public comment on the changes EPA is considering. Webinar access information will be provided upon registration, and materials will be emailed to registered participants prior to the webinar.

EPA is interested in your input! If you have comments or suggestions on revising the WaterSense High-Efficiency Lavatory Faucet Specification, please submit them to watersense-products@erg.com by April 26, 2024. Please forward this email to any other parties who might be interested in commenting on the NOI.

If you have questions, please contact the WaterSense Helpline at (866) WTR-SENS (987-7367) or watersense@epa.gov.
