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.
