    B. 
    Pressure tanks for individual home installations shall be diaphragm type and have a minimum capacity of 36 gallons.
    C. 
    Quantity tests shall be performed by competent pump or well drilling contractors and a well shall produce a supply for each dwelling unit served by an on-site well as follows:
    Well Drawing Depth

    0 to 150
    5 to 6
    150 to 200

    200 to 300
    3
    300 and over
    2
    D. 
    Auxiliary power must be available to maintain a water supply for multiple dwellings. The wall of a dug well shall extend at least four inches above the floor or the original ground surface.
    E. 
    A pitless adapter shall be provided such that the permanent watertight casing of the well shall terminate a minimum of 12 inches above finished grade and/or the elevation of one-hundred-year flood.
    F. 
    Well must be curbed and covered to prevent entrance or contamination and to divert surface drainage away from the well.
    G. 
    Pipes and equipment.
    (1) 
    All service pipes and connections shall be of nontoxic material and meet the specifications approved by the New England Water Works Association.
    (2) 
    The installation of pipes shall be such that they are protected from crushing, freezing and/or attack by rodents.
    (3) 
    Dissimilar metals should be discouraged in the water system. The use of nonconductive plastic inserts between pipes and fittings or the installation of sacrificial anodes is helpful in minimizing electric corrosion problems.

    Electrical service grounds shall not be attached to the water piping. All electrical service and controls of well must be permitted, inspected and approved according to Town and state regulations.
