This bill amends several sections of the Idaho Code related to domestic wells and water usage. It revises the definition of "domestic purposes" to clarify that it includes water use for homes, livestock, and limited irrigation, while excluding certain developments like mobile home parks and commercial establishments unless they meet specific diversion volume limitations. The bill also introduces the term "in-home use" to specify water usage within a household and defines "subdivision" in the context of land development. Additionally, it allows for multiple water rights for domestic purposes to be established from the same point of diversion, provided the use is limited to residential in-home activities.

Furthermore, the bill outlines new requirements for drilling and using wells for domestic purposes, particularly in subdivisions where a permit will be required for new diversions after July 1, 2025, in areas under moratorium or designated as critical groundwater areas. It also revises provisions regarding water delivery within subdivisions, ensuring that any subdivision application filed before June 30, 2025, is governed by the law as it existed at that time. The bill mandates that subdivision plats include specific notes regarding water rights and delivery systems, and it establishes compliance requirements for water systems associated with subdivision plats. An emergency clause is included, allowing the act to take effect immediately upon passage and approval.
