The bill amends various sections of the Idaho Code to clarify and revise the definitions and regulations surrounding domestic water uses. It redefines "domestic purposes" to encompass water for homes, livestock, and limited irrigation, while imposing new limitations on water rights for multiple ownership subdivisions and commercial establishments. The legislation introduces enforcement provisions that empower the director of the Department of Water Resources to notify property owners of excess water use and impose penalties for non-compliance. Additionally, it establishes regulations for the drilling and use of wells for domestic purposes, ensuring these activities are subject to inspection and licensing, and outlines a process for addressing violations, including civil penalties for excess use.

Furthermore, the bill introduces a new section, 31-3805, which sets requirements for subdivisions within the service area of a municipal provider, mandating the design of shared wells or public water systems to meet municipal standards and the conveyance of water rights to the municipal provider upon connection. It also repeals Section 31-3805 and amends other sections, including 31-3806, to clarify property owner liabilities for non-compliance with water delivery requirements. The bill emphasizes the need for comprehensive planning that considers groundwater sources and reinforces the use of surface water for irrigation where available. The legislation is scheduled to take effect on July 1, 2025.
