Fire hydrants shall be located as designated by the city engineer after consultation with the fire chief. All fire hydrants installed within the city shall be purchased from the director of public works who shall require payment equal to the cost to the city to purchase the hydrant.

(b)

Fire hydrants shall meet the requirements of AWWA C502. They shall be six-inch diameter hydrants with five and one-fourth (5¼) inch main valve openings, unless otherwise specified by the city engineer. They shall be equipped with dual two and one-half (2½) inch hose nozzles and one (1) size four and one-half (4½) inch pumper nozzle. They shall have a mechanical joint connection. They shall be of such length so that nozzles are at least fourteen (14) inches above ground and shall have replaceable "breakable" sections. They shall have a minimum burial depth of forty-eight (48) inches. Hydrant drainage shall be provided by placing around the hydrant, and below the top of the hydrant supply pipe, not less than seven (7) cubic feet of a mixture of two (2) parts gravel retained on a three-fourths-inch screen to one (1) part coarse sand.

(c)

All fittings, valves and fire hydrants shall be restrained using thrust blocks which meet city standards or restrained by other methods, such as retainer glands, or swivel fittings, which are acceptable to the city engineer. Only manufactured products will be acceptable as substitutes for the thrust blocks.
