The bill amends several sections of the Idaho Code to update regulations regarding domestic water uses, specifically redefining "domestic purposes" to include water use for homes, livestock, and limited irrigation, while excluding certain multi-unit residential and commercial uses unless they meet specific diversion rate and volume limitations. It introduces provisions for multiple water rights for domestic purposes from the same point of diversion for in-home use and addresses the drilling and use of wells, which are generally exempt from permit requirements but must comply with inspection and licensing provisions. The bill also establishes enforcement mechanisms for exceeding authorized water use limits, granting the director of the Department of Water Resources additional powers to suspend permits and enforce compliance.

Additionally, the bill enhances the management and delivery of water within subdivisions, focusing on integrating water systems with municipal providers and utilizing surface water for irrigation. A new section outlines requirements for subdivisions within the service area of a municipal provider, including the design of shared wells or public water systems to ensure compatibility. It mandates the use of surface water for irrigation if available and emphasizes the need to consider land use changes' impact on groundwater sources. The bill includes provisions for civil actions to enforce compliance with water delivery requirements, with the prevailing party entitled to reasonable costs and attorney's fees. It is set to take effect on July 1, 2025, aiming to align water management practices with state objectives while protecting property owners' rights.
