No water from any roof, surface, ground, sump pump, footing tile, swimming pool or other natural precipitation shall be discharged into the sanitary sewer collection system. Dwellings, including new housing construction or houses under construction, and other buildings and structures which require, because of the infiltration of water into basements, crawl spaces and the like, a sump pump system to discharge water shall have a permanently installed discharge line which shall not at any time discharge water into the sanitary sewer collection system. A permanent installation shall be one which provides for a year round discharge connection to the City subdrain/storm sewer system. If there is no subdrain available, the surface discharge point location shall be approved by the City Engineer. It shall consist of a rigid discharge line, without valving or quick connections for altering the path of discharge and, if connected to the City subdrain/storm sewer line, include a check valve.
