[Code 1975, § 19-3(21)]
No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process waters to any sanitary sewer, building sewer and/or private sewer, or to interior piping which in turn is connected directly or indirectly to a public sanitary sewer. Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm drains, or to a natural outlet approved by the Director. Industrial cooling water or unpolluted process waters may be discharged, on approval of the state Department of environmental protection, the Director, and the pretreatment manager, to a storm drain, combined sewer, or natural outlet. All new or altered connections to the sanitary sewer system shall conform with this section.
