This bill proposes several updates to existing statutes regarding water conservation plumbing requirements in Arizona. Key changes include the introduction of new definitions, such as "Watersense-labeled plumbing fixture" and "Watersense program," which establish standards for water efficiency based on the U.S. Environmental Protection Agency's program. The bill also modifies existing definitions, such as changing "and" to "or" in the definition of "commercial, industrial or public construction," and updating the terminology for "multifamily" dwellings. Additionally, the bill specifies that beginning January 1, 2027, plumbing fixtures must either be Watersense-labeled or meet certain water efficiency criteria established by the Watersense program.

Furthermore, the bill removes outdated language regarding specific water-saving performance standards for various plumbing fixtures, replacing it with broader categories that allow for more flexibility in compliance. It also mandates the installation of water-free urinals in new state buildings and encourages their installation in existing buildings. The bill clarifies that the requirements do not apply to plumbing fixtures purchased before January 1, 2027, and allows for waivers for historic fixtures. The effective dates for the amendments are set for December 31, 2025, and December 31, 2026, for different sections of the statutes.
