Bill Summary · HB 2053

Legislative bill overview

HB 2053 appropriates funding for stormwater recharge mapping and site identification in Arizona. The bill directs state resources toward identifying and documenting locations where stormwater can be captured and recharged into groundwater aquifers to address water sustainability challenges.

Why is this important

Arizona faces significant groundwater depletion, and stormwater recharge is a critical strategy for replenishing aquifers, particularly in urban and suburban areas. Mapping these potential recharge sites provides essential data for water managers, municipalities, and developers to implement green infrastructure and reduce reliance on depleting groundwater reserves.

Potential points of contention

  • Cost-benefit ambiguity: The bill's effectiveness depends on whether identified sites are actually developed for recharge, raising questions about return on investment
  • Implementation responsibility: Unclear delineation of which agencies (state vs. local) bear responsibility and costs for developing mapped sites into functional recharge infrastructure
  • Water rights complexity: Stormwater recharge intersects with existing water rights frameworks and may trigger disputes over who benefits from recharged water
