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 "multi-family" to "multifamily" and clarifying the definition of "water free urinal" to specify that it operates without water for waste disposal. Additionally, the bill sets a new compliance date of January 1, 2027, for the distribution, sale, or installation of plumbing fixtures in new residential and commercial constructions, replacing the previous date of January 1, 1994.

Furthermore, the bill removes outdated performance standards for plumbing fixtures and replaces them with a requirement that fixtures must either be Watersense-labeled or meet criteria established by the Watersense program before the compliance date. It also emphasizes the installation of water-free urinals in state buildings and allows for waivers for historic fixtures. The effective dates for the amendments to specific sections are set for December 31, 2025, and December 31, 2026, depending on the section.
