HB 2102 Arizona House · 57th Legislature - Second Regular Session

domestic water improvement districts; hauling

This bill amends Arizona law to clarify the authority of domestic water improvement districts, which manage water and wastewater systems in unincorporated areas. It specifically allows these districts to engage in water hauling (transporting water) as part of their operations and to make other local improvements like street maintenance, funded through special assessments or bonds. The bill defines key terms (e.g., "waterworks," "wastewater systems") and sets rules for including land in districts, requiring consent for state lands and permitting landowners to object to inclusion for large agricultural properties or mining claims. It primarily affects property owners in unincorporated areas where water systems are being developed or improved.

MODERATE
This bill updates Arizona's laws regarding domestic water improvement districts to explicitly authorize them to provide water hauling services in specific groundwater management areas. It expands the districts' powers to include acquiring water rights and constructing wells in sensitive environmental zones, while also clarifying definitions and procedures for including or excluding certain properties from these districts.
Scope change
The bill expands the scope of domestic water improvement districts to include areas designated as subsequent active management areas or specific groundwater basins, allowing these districts to legally haul water into these restricted zones.
SCOPE

Added explicit authority for improvement districts to construct and operate domestic water delivery systems that deliver water through hauling into subsequent active management areas and specific groundwater basins.

DEFINITION

Updated the definition of 'Waterworks' to include drinking water treatment facilities, wells, and pipelines necessary for hauling water to these new designated areas.

ELIGIBILITY

Modified the rules for establishing districts to allow noncontiguous areas if they are within six miles of an incorporated city or town, and clarified when state lands can be included.

ENFORCEMENT

Added specific limitations on the power of eminent domain, restricting its use to acquiring sites for wells and standpipes only within the newly authorized groundwater management areas.

REQUIREMENT

Clarified that districts formed for water hauling must obtain consent from nearby city or town governing bodies if their proposed boundaries are within six miles of such municipalities.
