(A) No person may discharge to public sewers any waste which, by itself or by interaction with other wastes, may:
(1) Injure or interfere with the wastewater treatment process or facilities;
(2) Constitute a hazard to humans or animals; or
(3) Create a hazard in receiving waters of the wastewater treatment plant effluent.
(B) All discharges exceeding the criteria for domestic wastewater shall be prohibited unless approved by the city. The criteria for domestic wastewater is the biochemical oxygen demand (BOD) concentration shall not exceed 300 mg/l and the total suspended solids (TSS) shall not exceed 300 mg/l.
(C) All industrial discharges of toxic pollutants are prohibited. Industrial wastewater which exceeds the limits for domestic wastewater, as defined above, shall be pretreated to reduce its concentration to that of domestic wastewater prior to discharge to the sanitary sewer system. The city may, at its option, require the industry to pay a surcharge for excessive strength wastewater in lieu of pretreatment of the excessive strength wastewater. In no case shall the industrial discharge interfere with the wastewater treatment processes or facilities, nor shall the industrial discharge create a hazard in the receiving waters of the wastewater treatment plant effluent.
(D) Any new connections from inflow sources into the sanitary sewer portions of the sewer system shall be prohibited.
(E) No person shall discharge or cause to be discharged the substances listed in § 53.09 of this chapter that can harm the sewer collection system or the wastewater treatment facility.
