A. If any waters or wastes are discharged, or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in Section 13.08.140 of this chapter, and which in the judgment of the governing body of the city may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the governing body of the city may:
1. Reject the wastes;
2. Require pretreatment to an acceptable condition for discharge to the public sewers; or
3. Require control over the quantities and rates of discharge.
B. If the governing body of the city permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the governing body of the city and the state, and subject to the requirements of all applicable codes, ordinances and laws.
