As the City develops and the cost of supplying water increases, the City Council finds it is in; the public interest to require a secondary water system in new developments so`the City's potable water supply is not used as the primary source of irrigation water. The City has considered such system in the past. Other cities in the area in Idaho and Utah are using secondary water systems and such a system is necessary with the costs of treatment and the strains being placed upon the Snake River Aquifer with the recent drought. The City currently has existing rights in the Fort Hall Irrigation project. To allow for the secondary system, any rights appurtenant to land to be developed shall used with the installation of a secondary water system to provide irrigation water which will ease the strain and costs to the City's potable water supply. Section 2. Now Section 16.23.230. The following section 16.23.230 shall be added to the Chubbuck Municipal Code: 16.12.230 SWgA&a'Pressure Irrigation Systems. All developments with appurtenant agricultural water rights shall be required to construct a secondary pressure irrigation system to the standards of this section to utilize the water rights for the development. Such secondary pressure irrigation systems shall be owned and operated by the system users, unless dedicated to and accepted by the city as a utility in which case the city will assume ownership and operation ' of the system. Dedication to the city shall generally be required unless circumstances cause the city to waive dedication. Secondary irrigation systems shall be designed and constructed in accordance with the following standards. A. Design Standards Ordinance - Page 1 chubbuck012507secondarysysad.wpd 0 • 1.

The maximum distance between shutoff valves shall be 1500 feet. 3.
