DOMESTIC WELLS – Amends existing law to revise provisions regarding the domestic use of water.

S 1222 revises Idaho's domestic water well laws to clarify what qualifies as "domestic use" and update related requirements. It defines domestic use as water for homes (up to 13,000 gallons daily for activities like drinking and cooking, including limited irrigation of half an acre) but excludes multi-unit housing, mobile parks, and commercial properties unless volume limits are met. The bill requires permits for new domestic water use in subdivisions after July 2025 in areas with groundwater restrictions, and mandates that subdivision water systems integrate with municipal systems or use available surface water for irrigation. These changes primarily affect homeowners, subdivision developers, and local water management entities in Idaho.
