ORDINANCE NO. 641
AN ORDINANCE OF THE CITY OF CHUBBUCK, IDAHO, ADDING SECTION
16.23.230 TO THE CHUBBUCK MUNICIPAL CODE TO REQUIRE ALL
DEVELOPMENTS TO INSTALL A SECONDARY PRESSURE IRRIGATION
SYSTEM IF THERE ARE AGRICULTURAL WATER RIGHTS ASSOCIATED WITH
THE LAND BEING DEVELOPED, SETTING STANDARD FOR SUCH SYSTEMS;
PROVIDING SUCH SYSTEMS MAY BE DEDICATED TO THE CITY AND, UPON
ACCEPTANCE, SHALL BE A UTILITY MAINTAINED BY THE CITY; REPEALING
PRIOR CONFLICTING ORDINANCES; PROVIDING FOR THE SEVERABILITY OF
THE PROVISIONS OF THIS ORDINANCE; AND PROVIDING WHEN THIS
ORDINANCE SHALL BECOME EFFECTIVE.
BE IT ORDAINED BY THE MAYOR AND COUNCIL OF THE CITY OF
CHUBBUCK, IDAHO;
Section 1. Intent. 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.

1. The system shall be designed to produce a minimum flow of 7 gallons per
minute at each service connection. The minimum pressure at this flow
shall be 45 PSI. The delivery system shall be capable of supplying one-
half the lots in a subdivision with the above pressure and flow
requirements.
2. The maximum distance between shutoff valves shall be 1500 feet.
3. The system shall be designed with adequate connections and valves to be
able to evacuate water from the piping with the use of compressed air and
also "stop and waste" valve assemblies at low points in the system.
4. Pumps, motors, filters, and controls shall be designed in accordance with
the current edition of the City of Chubbuck Pressure Irrigation System
Design Specification Manual, as now adopted, or as may be revised from
time to time. The Design Specification Manual is intended to describe a
pumping system which will provide a constant pressure in the distribution
system, with a potential for growth, using variable frequency drives and
parallel triplex pumping arrangements.
B. System Construction Standards
1. All work and materials shall conform to the Idaho Standards for Public
Works Construction (ISPWC), Section 901.
2. The requirement of Idaho Standards for Public Works, Standard Drawing
901; Item No. 6 shall be changed to require a compression fitting at the
curb stop.
3. The main distribution line shall be located within the street pavement area
and in accordance with the Idaho Regulations for Public Drinking Water
Systems, unless an alternative is approved by the city.
4. Curb stop, valve box and cover shall be located in the swale section on the
street side of the sidewalk, unless an alternative is approved by the city.
C. The provisions of this section may be temporarily or permanently waived by the

available and/or the delivery system for the water to the parcel served by the
water.
