A water distribution system shall be designed and constructed by the subdivider to provide water for all lots in the proposed subdivision. The distribution system shall be connected to the public water system unless otherwise authorized by the plan commission. The flow and pressure provided shall be adequate for domestic service and fire protection service.

    A.    Plans for a public distribution system must be approved by the Columbus city utilities. Plans for a distribution system (public or private) may also require approval by the Indiana Department of Environmental Management.

    B.    The water system shall provide flows acceptable to the Columbus fire department and shall have flows and levels of service sufficient to maintain an insurance services organization rating at least equivalent to that held by the city of Columbus.

    C.    The commission's seal shall not be affixed to the plat until the written approval from the Columbus city utilities is transmitted to the department.

    D.    Improvement plans for a permanent water system shall be provided showing pipe line sizes, type of pipe, location of hydrants and valves and if applicable, supply facilities, booster pumps, elevated or ground level storage tanks and other appurtenances. The following standards shall apply to all water systems:

    1.    Minimum size pipe will be determined by the type of district being served. Generally, water lines that are to supply water for emergency and fire fighting purposes shall be a minimum of six inches in diameter.

    2.    The maximum distance between fire hydrants shall be determined by the fire department. In no event though, shall any buildable area of the subdivision be located more than two hundred fifty feet from a fire hydrant.

    3.    All valves shall be so located so that no single break in the distribution system will cause more than five hundred feet of water main in the high value districts or more than eight hundred feet of water main in other districts, to be out of service. These valves shall be located so that a break in the secondary distribution system will not shut down major distribution mains.

    4.    All hydrants shall be individually valved.

    E.    For properties not served by a public or semi-public water supply system, each lot must have an adequate supply of potable water or an individual well. (Ord. 99-24 § 3 (part), 1999: Ord. 94-5 § 3 (part), 1994; prior code § 28-48)
