HB2097 is a bill that expands the definition of gray water to include wastewater from dishwashers or kitchen sinks without garbage disposals and mandates the Arizona Department of Environmental Quality (ADEQ) to establish rules by June 1, 2026, for the use or discharge of gray water at single-family residences and on residential rural land. It also allows property owners on residential rural land to be exempt from connecting to wastewater treatment facilities if they use composting toilets and gray water. The bill prohibits additional county zoning requirements or penalties regarding gray water or composting toilets and clarifies that building permits are not needed for gray water systems that meet ADEQ standards.

The bill redefines terms, renumbers definitions, and introduces a definition for "composting toilet." It also exempts gray water systems from being classified as "on-site wastewater treatment facilities" and outlines the legislative intent for the rules to be minimally burdensome and necessary for public health and safety. The bill aims to streamline regulations and encourage the use of alternative water and waste systems while ensuring public health and groundwater protection.
