A. 
This chapter sets uniform requirements for discharges into wastewater collection and treatment system and enables the City to comply with the administrative provisions of the Clean Water Act, the water quality requirements set by the Regional Water Quality Control Board and the applicable effluent limitations, national standards of performance, toxic and pretreatment effluent standards, and any other discharge criteria which are required or authorized by State or Federal law, and to derive the maximum public benefit by regulating the quality and quantity of wastewater discharged into those systems. This chapter provides for the setting of user charges and fees for the equitable distribution of costs to all users, the issuance of permits to certain users, authorizes monitoring and enforcement activities, and requires user reporting. Revenues derived from the application of this chapter shall be used to defray the City's cost of operating and maintaining an adequate wastewater collection and treatment system and to provide sufficient funds for capital outlay, bond service costs, capital improvements and depreciation.
B. 
The objectives of this chapter to comply with the Clean Water Act are:
1. 
To prevent the introduction of pollutants into the municipal wastewater system which will interfere with the operation of the system or contaminate the resulting sludge;
2. 
To prevent the introduction of pollutants into the municipal wastewater system which will pass through the system, inadequately treated, into receiving waters or the atmosphere or otherwise be incompatible with the system;
3. 
To improve the opportunity to recycle and reclaim wastewaters and sludges from the system; and
4. 
To provide for equitable distribution of the cost of the municipal wastewater system.
This chapter shall apply to the "City" and to persons outside the "City" who are, by contract or agreement with the "City," users of the "City" publicly owned treatment works (POTW). Except as otherwise provided herein, the Director of the Municipal Utilities Department shall administer, implement and enforce the provisions of this chapter.
