(A) (1) In the event a customer of the Municipal Sewer Department discharges an unusually large amount of waste daily, an unusually large amount of grease, sand, or oil, waste with an unusually high biochemical oxygen demand, or wastes containing excessive harmful or toxic wastes, the chief sewer official may require the customer to install interceptors or other preliminary treatment equipment to reduce the objectionable characteristics of the waste to within such maximum limits as he or she shall prescribe subject to the review of the City Council. All preliminary treatment facilities shall be purchased and maintained continuously in satisfactory and efficient operation at the customer's expense.
(2) Nothing herein shall be construed to prohibit a special agreement or arrangement between the City Council and an industrial concern whereby an industrial waste of unusual strength or character may be accepted by the municipality for treatment subject to additional rental fees or other charges.
(B) When required by the City Council, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling, and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the City Council. The manhole shall be installed by the owner at his or her expense, and shall be maintained by him or her so as to be safe and accessible at all times.
(C) (1) All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made herein shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater," published by the American Public Health Association, and shall be determined at the control manhole provided or upon suitable samples taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected.
(2) Sampling shall be carried out by customarily accepted methods to reflect the effect constituents have upon the sewage works and to determine the existence of hazards to life, limb, and property.
