Within 90 days after passage of this chapter, any person desiring to deposit or discharge any industrial waste mixture into the sewers of the city or any sewer connected therewith, shall make written application to the approving authority.
(Ord. 113, passed 10-13-76)
(A) The water consumption during the billing period, as determined from the meter records of the Water Department, shall be the valid basis for computing the wastewater flow, unless actual wastewater flow measurement by a recording meter of an approved type is required by either the approving authority or industry. The owner shall install and maintain such device in proper condition to accurately measure such flow. Upon failure to do so, the water consumption shall be the basis for determining the applicability of this subchapter and computing the industrial service charge. When water is obtained from a privately owned source, a water meter and/or wastewater meter satisfactory to the approving authority shall be installed and maintained at the persons expense.
(B) When water is contained in a product, is evaporated, or is discharged in an uncontaminated condition to surface drainage, an application may be made for a reduction in the volume of waste discharged to the public sewer, provided supporting data satisfactory to the approving authority is furnished. This data shall include a flow diagram, the destination of the water supply and/or waste, and supported by submetering data obtained on the process piping at the expense of the private owner.

INDUSTRIAL DISCHARGE REQUIREMENTS
This chapter controls the material which can be discharged to the city sanitary sewer system. The industries must provide, operate, and maintain adequate pretreatment facilities as necessary to prevent damage, plugging, or overloading from their process waste to the city wastewater collection and pumping systems and to prevent loading of the city wastewater treatment facility in excess of the design criteria.
(Ord. 141, passed 11-6-89)
(A) The discharged wastewater flow and loading characteristics shall be controlled to the limitations given in the Major Contributing Industry Treatment Agreement levels for that particular industry.
(B) The parameters shall be based on analysis of a 24-hour flow - proportionate composite sample.
