Discharging to Sewers

It is a violation of City Ordinance (53.021) to discharge to any natural outlet or storm drainage system within the city, any wastewater or other polluted waters, except where suitable treatment or management has been provided.

In addition it is a violation for any unpolluted waters such as stormwater, groundwater, roof runoff, subsurface drainage, to be discharged to the City sanitary sewer system. Owners of any building sewers having such connections, leaks, or defects are responsible for eliminating these sources and any cost associated with their removal.

Any substance that will interfere with operation or performance of the sanitary sewer system or the treatment process is prohibited.

Do Not Flush

  • Solid or viscous substances in quantities or size capable of causing obstruction to the flow, or other interference with the proper operation of the pumps and treatment equipment, e.g. glass, metal, plastic items, soil, sand, ashes, diapers, sanitary napkins or tampons, rags or clothes (this includes wipes of any kind; even those labeled flushable).
  • Any waters or wastes having a pH lower than 5.5 or higher than 10.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the treatment plant.
  • Any wastewater having a temperature which will inhibit biological activity in the treatment plant or any wastewater that will result in temperatures in excess of 104° F (40° C) coming into the treatment plant.
  • Any substance which will cause the treatment plant to violate its NPDES/KPDES Permit and/or sludge disposal system permit.
