A. All water line plans must be designed and sealed by a registered licensed professional engineer in the state of Idaho.
B. All water lines and water wells shall be designed in accordance with requirements of water resources or department of environmental quality as required by law.
C. Minimum water main size shall be six inch (6") diameter. Larger sizes shall be as required by the city's water main master plan or as are needed to provide adequate water quantity and pressure to the area (and surrounding developable area) being developed and/or annexed to the city.
D. Water lines shall have at least five feet (5') of cover (from the top of water line pipe to the ground or street surface).
E. All dead end water lines shall have a fire hydrant or approved type of flush out valve installed on the end thereof.
F. Fire hydrants shall be located no more than four hundred feet (400') apart within residential areas. Within commercial or industrial areas, there shall be one fire hydrant for every eighty thousand (80,000) square feet of subdivision or development area (including streets and alleys) with the fire hydrants located in proximity to the buildings as approved by the public works director. Sprinkling systems may be required within the interiors of buildings having a high potential fire hazard or fire risk.
G. Water lines shall be valved at every intersection so that every block of city water line can be shut off and isolated from the rest of the water system to facilitate maintenance and repair work while keeping public inconvenience to a minimum. Where blocks are exceptionally long, additional valves shall be installed at such additional approved locations as are necessary so that no more than a six hundred foot (600') length of water line has to be shut off or out of service at any one time to accommodate repairs, etc.
H. Water lines and sanitary sewer lines shall, whenever possible, be located on opposite sides of the street. Preferably, water lines shall be located thirteen feet (13') west or north of the street centerline and the sanitary sewer at thirteen feet (13') east or south of the street centerline. Where storm drains are needed, these shall preferably be located along the street centerline. The above referenced locations and dimensions may be varied to accommodate unusual circumstances; however, a ten foot (10') (out to out) horizontal separation between water line facilities and sewer facilities (either sanitary or storm) and an eighteen inch (18") (out to out) vertical separation between said facilities shall always be maintained unless a specific variance to this requirement is obtained from the Public Works Director. The applicable separation requirements of Water Resources or Department of Environmental Quality as required by law shall also be complied with.
I. All drawings shall be on linen or mylar in pencil or ink, and of such quality that they clearly show the dimensions, locations, sizes, etc., of all facilities represented thereon. All water line appurtenances shall be clearly shown and identified by name and by station or other means of horizontal location. Water lines shall be shown in both plan and profile if other utilities such as sanitary sewer or storm drain will be adjacent to said water line. If a profile of the water line is not provided, it shall be located in the vertical plane by elevations on the top of the pipe at all fittings, valves, etc., and at intervals not exceeding two hundred feet (200'). Drawings shall be drawn on a scale of one inch equals one hundred feet (1" = 100'), unless the amount of detail, topography, etc., necessitates their being drawn on a larger scale (i.e., one inch equals 50 feet or one inch equals 40 feet) to provide the clarity and completeness needed on the drawings.
J. The design of all water lines and all water line plans must be approved by the Public Works Director. (1980 Code § 4.6.45; amd. 1999 Code)
