(A) No person shall discharge or cause to be discharged any storm water, surface water, ground water, roof runoff, subsurface drainage, cooling water or unpolluted industrial process waters to any sanitary sewer.
(B) No person shall discharge or cause to be discharged to any public sewer, any harmful water or wastes, whether liquid, solid or gas, capable of causing obstruction to the flow in sewers, damage or hazard to structures, equipment and personnel of the sewage works, or other interference with the proper operation of the sewage works.
(C) Grease, oil and sand interceptors shall be provided when, in the opinion of the said inspector, they are necessary for the proper handling of liquid wastes containing grease in excessive amount, or any flammable wastes, sand and other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. Where installed, they shall be maintained by the owner, at his or her expense, in continuously efficient operation at all times.
(D) The admission into the public sewers of any waters or wastes having harmful or objectionable characteristics shall be subject to the review and approval of the Superintendent. Where necessary, in the opinion of the Director of Public Works, the owner shall provide at his or her expense, such preliminary treatment as may be necessary to treat these wastes prior to discharge to the public sewer. Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Director of Public Works and of the State Board of Health, and no construction of such facilities shall be commenced until said approval is obtained in writing. Where preliminary treatment facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
(E) When required by the Director of Public Works, the owner of any property served by a building sewer carrying industrial wastes shall install and maintain, at his or her expense, a suitable control manhole in the building sewer to facilitate observation, sampling and measurement of the wastes. All measurements, tests, and analysis of the characteristics of water and wastes shall be determined in accordance with Standard Methods for the Examination of Water and Sewage, and shall be determined at the control manhole or upon suitable samples taken at said 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.
(F) No statement contained in this chapter shall be construed as preventing any special agreement or arrangement between the city and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the city for treatment, subject to payment therefor by the industrial concern.
