Official statutory text

42-111. Domestic purposes defined. (1) For purposes of sections 42-221, 42-227, 42-230, 42-235, 42-237a, 42-242, 42-243, and 42-1401A, Idaho Code:

(a)(i) "Domestic purposes" or "domestic uses" means:

1. The use of water for homes, organization camps, public campgrounds, livestock, and for any other purpose in connection therewith, including irrigation of up to one-half (1/2) acre of land, if the total use does not exceed thirteen thousand (13,000) gallons per day; or

2. The use of water for any other purpose, if the total use does not exceed a diversion volume of two and eight-tenths (2.8) acre feet per year.

(ii) "Domestic purposes" or "domestic uses" shall not include water for the following purposes, unless the use meets the diversion volume limitations set forth in paragraph (a)(i)2. of this subsection:

1. Mobile home parks or recreational vehicle parks;

2. Apartments, condominiums, and similar developments with multiple dwelling units;

3. Subdivisions, except as provided in subsection (3) of this section; or

4. Commercial or business establishments or mixed-use establishments where the water is used primarily for commercial or business purposes.

(b) "In-home use" means the utilization of water within a residence or household, including all activities that require water, such as drinking, cooking, bathing, and cleaning within and around the household. It does not include irrigation of lawns, gardens, landscaping, pastures, or other open spaces.

(c) "Subdivision" means a tract of land divided into five (5) or more lots, parcels, or sites for the purpose of sale or building development, whether immediate or future; provided that this definition shall not include a bona fide division or partition of agricultural land for agricultural purposes. For purposes of this paragraph, "bona fide division or partition of agricultural land for agricultural purposes" means the division of land into lots, all of which are five (5) acres or larger and maintained as agricultural lands.

(2) Except as provided in subsection (3) of this section, multiple water rights for domestic uses or domestic purposes shall not be established or exercised in a manner to satisfy a single combined water use or purpose that would not itself come within the definition of a domestic use or purpose under this section. The purpose of this limitation is to prohibit the diversion and use of water, under a combination of domestic purposes or domestic uses as defined in this section, to provide a supply of water for a use that does not meet the exemption of section 42-227, Idaho Code, and is required to comply with the mandatory application and permit process for developing a right to the use of water pursuant to chapter 2, title 42, Idaho Code.

(3) Multiple water rights for domestic purposes or uses may be established and exercised from the same point or points of diversion if the use is limited to residential, in-home use. This subsection does not affect any other permitting requirement or other requirement that may apply to the use of water within a subdivision.
