(A) All subdivisions and/or mobile home villages shall be provided, by the subdivider, with a complete water distribution system from an approved public water distribution system. The residential subdivision property is considered to be one- and two-family dwellings. The water distribution system shall provide fire hydrants at intervals of not more than 750 feet on six-inch or larger mains unless a different spacing is expressly approved by the Plan Commissioners because of special land use or density consideration. All fire hydrants and water mains shall be designed by a registered professional engineer following the guidelines indicated herein, and follow standards of the AWWA (American Water Works Association). Exceptions may be made by the Commissioners in areas where rural water corporations may supply water.
(B) Rental fees of fire hydrants and/or water supply systems shall be the sole responsibility of the subdivider until such time as the city shall accept the subdivision.
(C) In determining water supply and fire hydrant requirements the office of the Fire Chief shall review the developer's proposed plans of the fire protection facilities and shall submit recommendations before approval of the plans. Placing of hydrants requires a judgment and a feeling for the needs of the Fire Department. Hydrant placement is based on the possibility of a large fire occurring in the area.
(D) Special exceptions may be made in the best judgment of the Plan Commissioners with approval of the Fire Chief.
(E) The size of water mains involves many variables. The following guidelines shall be considered as minimum for localized distribution.
(1) Water mains shall not be less than six inches in diameter. Where deemed necessary to provide an adequate water supply for fire protection, water mains of a larger diameter may be required.
(2) The gridiron shall consist of mains at least six inches in size, arranged so that the length between intersection mains does not exceed 800 feet.
(3) Eight-inch pipe shall be used where dead-ends and poor gridironing are likely to exist for a considerable period or where the layout of the streets and topography are not well adapted to the following arrangements. Where dead-ends are necessary, minimum main size should be eight-inch if over 600 feet, ten-inch if over 2,500 feet. Where the gridiron does not exceed 600 feet, a six-inch main is usually satisfactory; if wider, eight-inch or larger mains are recommended.
(4) The distribution system shall be equipped with a sufficient number of valves so located that no single accident, breakage or repairs to the pipe system will necessitate the shut-down of a length of pipe greater than 800 feet.
(5) Where it is necessary to meter the water supply for fire protection, the meter shall be of the fire protection type and be of at least six inches in size.
(6) Fire hydrants shall be spaced no further than 750 feet apart in residential subdivisions.
(7) In a single-family dwelling area where 20 feet or more separation is typical, a minimum supply of 1,000 GPM is desirable.
