(A) Any person having a roof, surface water drain or pump for surface or subsurface water drainage which now discharges water directly or indirectly into the public sewer shall within 60 days of receipt of written notice from the city, disconnect the same and plug the opening of the sanitary sewer. The opening to the sanitary sewer shall be permanently plugged.
(B) Every building without a yard adequate to absorb the surface water collected from such building shall be equipped with proper leaders for conducting water from its roof in such a manner as shall protect the walls and foundation from damage, and shall be connected with a storm sewer whenever such sewer exists within 50 feet of such building and abutting street. Such leaders shall be so placed and such connections shall be so made that no water flows upon any sidewalk or damages any street abutting such building.
(C) Discharge lines from footing drains, sump pumps, rainwater leaders, or any other method of conducting subsurface or storm water shall be constructed so as to be permanently installed without being easily able to switch connections allowing subsurface or storm water to run into the sanitary sewer. Prohibited methods of installation include:
(1) Flexible tubing or hose.
(2) Valves allowing switching to sanitary sewer.
(3) Discharge across the floor to floor drains, water closets, or sinks.
(4) Discharge out open windows where flows may return to the building.
(D) Buildings that are under construction (open foundations or not roofed) where there is the possibility of rainwater or storm runoff entering the sanitary sewer during or after rains shall have the building drain its laterals and inlets plugged and water tight to prevent inflow and infiltration.
(E) It is unlawful for any person permitted to construct or reconstruct a building sewer to knowingly allow the perpetuation of any storm water, groundwater, roof runoff, surface drainage, or non-contact cooling water discharge connection to the sanitary sewer.
