A.    General Requirements. An accessible, adequate, safe and potable supply of water shall be provided in each mobilehome park. Where a public supply of water is available at or near the site, connection shall be made thereto and its supply used exclusively. When a public water supply is not available, a private water supply system may be developed and used as recommended by the city engineer(s) and approved by the Illinois Environmental Protection Agency and the city council.

    1.    Source and Volume of Supply for Private Systems. The water supply shall be capable of supplying a minimum of two hundred fifty (250) gallons per minute for a duration of two hours.

    2.    The water supply shall be capable of supplying a minimum of three hundred (300) gallons per day per mobilehome.

    3.    The number of mobilehome spaces to be occupied in the mobilehome park shall be limited to the quantity of water necessary to supply each mobilehome with the minimum requirements.

    B.    Tests. The operator of a private water supply system shall obtain bi-monthly water quality tests from the Illinois Environmental Protection Agency, and shall forward one copy of that report to the city clerk.

    C.    Main Size. The water distribution main serving the confines of the mobilehome park shall not be less than six inches in diameter.

    D.    Connection. The water piping system shall not be connected with nonpotable or questionable water supplies and shall be protected against the hazards of backflow or siphonage.

    E.    Pressure. The system shall be so designed and maintained as to provide a pressure of not less than twenty (20) pounds or not more than eighty (80) pounds per square inch, under all normal operating conditions at each mobilehome pad.

    F.    Separation. Water mains, if installed parallel to sewer lines, shall be separated at least ten feet horizontally from any sanitary sewer, storm sewer or sewer manhole.

    G.    Individual Water Riser Pipes and Connections.

    1.    Individual water riser pipes shall be located within the area of the mobilehome pad.

    2.    Water riser pipes shall extend at least four inches above ground elevation. The pipe diameter shall be at least three-quarter inch. The water outlet shall be capped when a mobilehome does not occupy the lot.

    3.    Adequate provisions shall be made to prevent freezing of service lines, valves and riser pipes and to protect risers from heaving and thawing actions of the ground during freezing weather. Surface drainage shall be diverted from the location of the riser pipes.

    4.    A shut-off valve below the frost line shall be provided near the water riser pipe on each mobile-home space or lot. (Prior code § 23-2-25)
