HB 2095 Arizona House · 57th Legislature - Second Regular Session

assured water supply; well depth

HB 2095 requires developers to obtain either a "certificate of assured water supply" from the state director or a written commitment from a designated city, town, or private water company before selling subdivided land in Arizona's active management areas. It directly affects land developers and real estate transactions, mandating proof of sufficient water supply for new subdivisions. Key provisions include designating cities/towns/private providers with assured water supply (especially those using Central Arizona Project water), exempting mineral extraction developments, and allowing gray water systems to reduce water demand requirements under specific conditions. The bill title mentions "well depth," but the actual text focuses on water supply verification processes, not well depth regulations. This is a procedural requirement for land sales, not a substantive water policy change.

MODERATE

The bill was reorganized and modernized to clarify the requirements for obtaining an 'assured water supply' certificate for new subdivisions. It added specific rules for gray water reuse systems to reduce water demand and introduced a 'successor' provision to ensure water conservation rules remain in effect if a municipal water provider fails. The bill also updated the definition of 'assured water supply' to include stricter criteria regarding groundwater depth and financial capability, and added a requirement for the director to study whether building permits for multi-residence projects should also require water certificates.

Scope change

The bill's scope was expanded to explicitly include gray water reuse systems as a factor for reducing water demand and to cover situations where a municipal water provider's designation lapses, ensuring conservation rules still apply to successor providers.

REQUIREMENT

Added a new subsection requiring gray water reuse systems to meet specific departmental rules to qualify for a reduction in water demand for water supply certificates.

Added a new subsection establishing that if a municipal provider's water supply designation lapses, the successor provider must continue to comply with conservation rules for existing uses.

DEFINITION

Updated the definition of 'assured water supply' to include specific depth-to-bedrock limits (1,100 feet in Pinal County and 1,000 feet in Phoenix) and stricter criteria for groundwater availability over a 100-year period.

TIMELINE

Added a new requirement for the director to study and report by December 31, 2023, on whether building permits for six or more residences should require water supply certificates.

TECHNICAL

Reformatted the entire text to correct line breaks, remove obsolete dates (e.g., 1997), and update the bill header to reflect the 2026 legislative session.
