Latest version.
  • (a)

    Generally. Pretreatment of waste prior to discharge may be required by the city pursuant to this division, or such pretreatment may be employed by the discharger and used in order to comply with the prohibitions and limitations set forth in this division. In any of these or other cases where pretreatment is employed or required, the pretreatment process shall comply with the requirements of this section.

    (b)

    Application for permit. Where pretreatment prior to discharge is required, employed or proposed, a description of the pretreatment process shall be included in the permit issued to the discharger, and such pretreatment shall be expressly made a condition of the permit. As part of the material in support of the application for such a permit, or at any other time the city may require, the discharger using or proposing to use pretreatment shall, prior to commencement of construction, submit plans, specifications and other pertinent data or information relating to such pretreatment or flow-control facilities, for the review and approval by the city. All such plans shall be prepared by a state registered professional engineer and shall bear his signature and seal. Any subsequent alterations or additions to such pretreatment or flow-control facilities shall not be made without due notice to and prior approval of the city.

    (c)

    Operation. If pretreatment or control of waste flows is required, such facilities shall be maintained in good working order and operated as efficiently as possible by the owner or operator at his own cost and expense, subject to the requirements of the rules and regulations of this section and all other applicable codes, ordinances and laws.

    (d)

    Dilution not acceptable. The alteration of the characteristics of a polluted wastewater, to attain the limits for admission to either the public sanitary sewerage system or to attain the limits for discharge to a private sewage disposal system or receiving streams, by means of dilution, will not be allowed as an acceptable pretreatment process. The objective of an acceptable pretreatment process shall be the removal of the pollutants from the wastewater to the required level.
