(A) New water facilities shall be designed in accordance with the Arizona Department of Environmental Quality (ADEQ) and the Arizona Department of Health Services Bulletin No. 10 (latest edition). Any deviation from the bulletin’s requirements shall have the written approval of the City of Show Low.

(B) All water mains shall be a minimum of eight (8) inches in diameter or designated otherwise by the public works director to minimum water flow requirements of the pressure zone or the Show Low comprehensive water master plan. A water main with a minimum of six (6) inches in diameter may be used with approval of the public works director if a short dead-end line cannot be extended in the future.

(C) All water mains shall be C-900 or ductile iron; valves and fittings shall be constructed with materials having a working pressure rating of two hundred (200) pounds per square inch.

(D) All dead ends on new mains shall be provided with a blow-off assembly or fire hydrant in the plug or cap. The assembly shall be mechanically restrained.

(E) Fire hydrants shall be located in accordance with the current adopted fire code. The measurement between fire hydrants shall be linear and the measurement will be effected along the centerline of the streets. Fire hydrant flow testing requirements are in accordance with the American Water Works Association M17 Manual (latest edition).

(F) The water system for the subdivision must be capable of supplying and sustaining the required flows for fire protection throughout all subdivided properties as approved by the city. For residential areas, the minimum required fire flow capability is one thousand (1,000) gallons per minute for a duration of two (2) hours with a minimum system pressure of twenty (20) pounds per square inch while the required fire hydrant flow rate is being met. For all multifamily, industrial and commercial areas the chief building code official, in consultation with the Show Low fire district, shall determine minimum fire flow capability and that flow will be provided with a minimum system pressure of twenty (20) pounds per square inch.

(G) The approval of the final design of the water system rests with the City of Show Low and will be based on the conformity of the design to policy, standards, and specifications. The developer is responsible for all approvals with ADEQ and other regulatory agencies.

(H) The City of Show Low may issue building permits after the approval of the water system and the installation of an all-weather road. Approval of the water system requires that the water lines have been successfully pressure tested and disinfected to city standards and that fire flow can be provided. An all-weather road for this purpose means that the sub-grade and aggregate base material has been constructed to the approved plans and specifications and the width of the road is a minimum of twenty (20) feet. Water service shall not be connected to any structures until approval from ADEQ is received.

(I) The city will not issue any certificates of occupancy until the subdivision improvements are accepted for maintenance and operation by the city council. (Ord. No. 2008-12, §§ 1, 2, 9-16-08; Ord. No. 2019-02, § 1, 2-5-19. 1976 Code § 12-4(g))
