The Energy Policy and Conservation Act, as amended, 42 U.S.C. 6291–6309 (EPCA) establishes energy conservation or water use standards and test procedures for certain consumer products, including urinals. Title 10 of the Code of Federal Regulations, Part 430 (10 CFR 430), defines the term “urinal” to mean a plumbing fixture which receives only liquid body waste and, on demand, conveys the waste through a trap seal into a gravity drainage system, except such term does not include fixtures designed for installation in prisons. (10 CFR 430.2)  The Department of Energy (DOE) last amended the test procedures for urinals on September 30, 2013.  Under the provisions of 42 U.S.C. 6295(k)(3), the water use standards for urinals have not been amended.

Recent and Ongoing Activities

DOE has published a Federal Register final rule pertaining to test procedures for water closets and urinals. This final rule amends the test procedures for water closets and urinals to reference the most recent update to the relevant industry standard, American Society of Mechanical Engineers (ASME) Standard A112.19.2-2018. In this final rule, DOE is also amending certain definitions and adding definitions for certain terms that are currently used in the Federal test procedures but are not defined.

  • The effective date of this rule is April 22, 2022.
  • The final rule changes will be mandatory for product testing September 19, 2022.
  • The incorporation by reference of certain material listed in this rule is approved by the Director of the Federal Register April 22, 2022.

For the latest information on the planned timing of future DOE regulatory milestones, see the current Office of Management and Budget Unified Agenda of Regulatory and Deregulatory Actions. All planned dates are preliminary and subject to change.


The Energy Policy Act of 1992 amended EPCA to add water conservation standards for urinals, based on the flush volume requirements contained in American Society of Mechanical Engineers (ASME)/American National Standards Institute (ANSI) Standard A112.19.6-1990, which are codified under Title 42 of the U.S. Code (42 U.S.C.) section 6295(k).  Under 42 U.S.C. 6295(k)(3), if the flush volume requirements contained in ASME/ANSI Standard A112.19.6 are amended to improve efficiency of water use, the Secretary of Energy shall consider establishing an amended uniform national standard at the level specified in the amended ASME/ANSI Standard.  To date, ASME has not updated the flush volume requirements for urinals.

Current Standard

The flush rate of a urinal manufactured and distributed in commerce, as defined by 42 U.S.C. 6291(10) and (16) respectively, must be not greater than the maximum water use standards under 10 CFR 430.32(r).

Current Test Procedure

To determine whether a urinal is in compliance with the water consumption standards under 10 CFR 430(r), a manufacturer must measure the maximum flush volume in accordance with 10 CFR 430, Appendix T to Subpart B.

State Exemptions to Federal Pre-emption

A State may petition DOE for exemption from preemption of a Federal water conservation standard in certain cases of unusual or compelling State or local water interests.  A State may also petition DOE to withdraw such exemption. See 10 CFR part 430, subpart D.  DOE has not exempted any State from this water conservation standard.

On December 22, 2010, DOE published in the Federal Register a final rule to waive the general rule of Federal preemption for water use standards, under 42 U.S.C. 6297(c), with respect to any State regulation concerning urinals if such State regulation is (1) more stringent than Federal regulation concerning the water use or water efficiency for that same type or class of product, and (2) applicable to any sale or installation of all products in that particular type or class.  75 FR 80289.

Small Business Exemptions

Any manufacturer of a covered product with annual gross revenues that do not exceed $8,000,000 from all its operations and meets certain other conditions may apply for an exemption to the energy conservation standard. For details, see 10 CFR part 430, subpart E.
