Latest version.

  • M 1 Swimming pool waste water shall be disposed of as hereinafter set forth in this Section and the type of disposal proposed shall be approved by the Authority Having Jurisdiction prior to the commencement of any work. A means of disposal of the total contents of the pool (periodic emptying) without surface runoff shall be established to the satisfaction of the Authority Having Jurisdiction.

    (Ord. 2007-0110 § 7 (part), 2007: Ord. 99-0042 § 38 (part), 1999.)

    M 2 The following are legal methods of swimming pool waste water disposal.

    (1)

    To a public sewer.

    (2)

    On the property if the property is large enough to ensure that runoff will not encroach on abutting property.

    (3)

    To a tank truck.

    (4)

    In the case where none of the above can be accomplished, alternate methods of disposal acceptable to the State Regional Water Quality Control Board (SRWQCB) may be used. Prior to discharge, the swimming pool water must be tested by the owner to insure that it is within all water quality standards established by the SRWQCB. Contact Department of Public Works, Environmental Programs Division for information.

Plans and specifications for all indoor installations shall be submitted to the Authority Having Jurisdiction for approval prior to the commencement of any work, and all piping, equipment and construction shall be equal to the types prescribed in the Installation Requirements of this Code for indoor work.
