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or public construction," and updates the criteria for plumbing fixtures that can be distributed or installed, replacing outdated performance standards with new requirements that align with the Watersense program.

Additionally, the bill sets a new compliance date of January 1, 2027, for the distribution, sale, or installation of plumbing fixtures in both residential and commercial settings, replacing the previous date of January 1, 1994. It also allows for the sale of plumbing fixtures purchased before the new compliance date and grants the director the authority to waive requirements 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.
