No person shall cause or permit to be deposited or discharged into any such sewer, any water or sewage or liquid waste of any kind containing chemicals, grease, oils, tars or other matters in solution or suspension, which may, by reason of chemical reaction or precipitation, clog, obstruct or fill the same, or which may in any way damage or interfere with or prevent the effective use thereof, or which may necessitate or require frequent repair, cleaning out or flushing of such sewer to render the same operative, or which may obstruct or cause an unwarranted increase in the cost of treatment of the sewage.

No person shall discharge into the public sewer uncontaminated cooling water or clear wash water that is non-septic or incapable of becoming a public nuisance, where it is possible, as determined by the City Engineer, to dispose of such wastes into a stream channel or storm drain under the provisions of pertinent County ordinances and the regulations of the County Flood Control District. For the purpose of this subsection "storm drain" also includes a storm drain under the jurisdiction of the City.

No person owning or operating a private or public automobile wash rack shall permit any water or effluent therefrom to flow into any public sewer or house connection sewer unless such wash rack is roofed over and is equipped with a standard sand and grease interceptor approved by the City Engineer.

Any cellar drain or any shower in a basement or roofed shower in a yard shall be protected to prevent the admission of sand, detritus, and storm or surface water into the sewer. When necessary in the opinion of the City Engineer, a person shall trap such appurtenances by a sand interceptor constructed in accordance with the provisions of this Chapter.

No person shall connect any special waste pipe from any establishment directly to any public sewer or to any house connection sewer leading thereto. Such special waste pipe shall discharge into a water supplied sink or similar plumbing fixture, which may in turn be connected to the sewer.

No person shall cause or permit the exhaust from any steam engine or the blow-off from any boiler to be discharged directly into any public sewer or to any house connection sewer leading thereto.

Every such trap or valve be installed in

the basement, or in a box or man-hole of concrete, cast iron, or other material approved by the City Engineer, so that it will be readily accessible at all times.

No person shall discharge into the public sewer effluent of a temperature exceeding one hundred forty (140) degrees fahrenheit.

7475. • REIMBURSEMENT FOR DAMAGE.

Whenever an industrial sewer connection permittee, by reason of violation of Section 7472 hereof, or any person by reason of violation of Section 7473, causes obstruction, damage or destruction of a public sewer, he shall reimburse the City for the cost of flushing, cleaning, repairing and reconstruction of such sewer made necessary by such violation within thirty (30) days after the City shall render an invoice for same.
