Oil separators installed in any building where volatile fluids are used must not be connected directly or indirectly with a sewer.
C. Excess Residential Waste: Unless permitted, it shall be unlawful for any person to discharge, or cause to be discharged into the public sewer system, waste that is deemed by the city to be in excess, or abnormal from that expected from a typical residential user. Abnormal residential discharge includes, but may not be limited to, excess flow, excess total suspended solids (TSS), and excess biological oxygen demand (BOD). Discharge of these wastes may be permitted if additional charges and/or conditions are imposed by the city.
D. Waste From Certain Establishments: The contents of waste pipes from water filters, gas engines, air compressors, vacuum or dry cleaners, garages, wash racks, stores or warehouses containing inflammable substances, car barns, buildings for the stabling or keeping of horses, cows and other animals, or plants using milk or processing milk products, shall not be disposed of through connection with a sanitary sewer, unless such contents are discharged into settling tanks properly trapped and vented. The construction of such tanks must be approved by the city engineer, and must be subject to his inspection, approval or condemnation before cement is poured and at all times thereafter until completion of such construction. Upon condemnation by the city engineer, the sewage from the tanks shall not be allowed to flow into the sewer until satisfactory alterations have been made and the construction approved by the city engineer.

No boiler or heating plant shall be directly connected to the sanitary sewer. The overflow from boilers or heating plants, when cooled to a temperature not to exceed one hundred twenty degrees Fahrenheit (120°F), will be allowed to run to a sump, which sump shall be connected to the sewer. The discharge of the contents of waste pipes from water filters, gas engines, air compressors, vacuum or dry cleaners, garages, wash racks, stores or warehouses which contain inflammable substances, buildings for the stabling or keeping of horses, cows and other animals, and all similar establishments, shall not be made into or connected with a sanitary sewer, unless such contents are discharged into settling tanks properly trapped and vented. Settling tanks shall be constructed of a material approved by the public works director and shall be at all times subject to his inspection and approval or condemnation. Upon condemnation by the public works director, the sewage from said tanks shall not be allowed to flow into sewer until satisfactory alterations have been made and the construction approved by the public works director.
G. Control Of Harmful Waste: If any water or wastes are discharged, or are proposed to be discharged to the public sewer system, which contain the substances or possess the characteristics enumerated in this section, or which are determined by the city to have a deleterious effect upon the wastewater facilities, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the city may:
1. Reject the wastes;
2. Require pretreatment to and acceptable condition for discharge to the public sewers;
3. Require control over the quantities and rates of discharge, and/or wastes not covered by existing taxes or sewer charges under the provisions of this chapter.
