ORDINANCE NO. 2022-09 SAINT ANTHONY VILLAGE, MINNESOTA AN ORDINANCE AMENDING SECTION 50.16 OF CHAPTER 50 STORM WATER AND SANITARY SEWERS The City Council of the City of Saint Anthony Village ordains as follows: Section One. Amendment to the City of Saint Anthony Village City Code to Amend Section §50.16 Prohibited Discharges into Sanitary System , of the City Code of the City of Saint Anthony Village is hereby amended as follows. The deleted language is represented by strikethrough text. The additional language is represented by single underlined text. Section Two. Effective Date. This Ordinance amendment shall be in full force and effect upon its publication as provided by law. § 50.16 PROHIBITED DISCHARGES INTO SANITARY SYSTEM. (A) No person shall discharge or cause to be discharged any substance not requiring treatment or any substance not acceptable for discharge, as determined by the city, Minnesota Pollution Control Agency, or Metropolitan Council Environmental Services, into the sanitary sewer system. Only sanitary sewage from approved plumbing fixtures may be discharged into the sanitary sewer system. (B) No person shall discharge or cause to be discharged, directly or indirectly, any storm water, surface water, groundwater, roof runoff, subsurface drainage, or cooling water into the sanitary sewer system. Any person having a roof drain, sump pump, foundation drain, unauthorized swimming pool discharge, cistern overflow pipe, or surface drain connected and/or discharging into the sanitary sewer system shall disconnect and remove any piping or system conveying the water to the sanitary sewer system. (C) All construction involving the installation of clear water sump pits shall include a sump pump with minimum size 1-1/2 inch diameter discharge pipe. The pipe attachment must be a rigid permanent type plumbing such as PVC or ABS plastic pipe with glued fittings, copper, or galvanized pipe. All discharge piping shall be installed in accordance with the plumbing code and shall be without valving or quick connections or flexible sections which allow redirection of the sump pump discharge into the sanitary sewer system. Discharge piping shall start at the sump pit and extend through the exterior of the building and terminate with not less than 6 inches of exposed pipe. Sump pump discharge location and flow shall be consistent with the approved development drainage plan for the lot. The discharge may not be pumped directly onto any public right-of-way unless approved by the Public Works Director or his or her designee. Any disconnects or openings in the sanitary sewer shall be closed and repaired in compliance with applicable codes. (A) Applicability and purpose. This section shall apply to all water entering the sanitary sewer system unless explicitly exempted by the city. The city and its representatives are authorized to administer, implement, and enforce the provisions of this section. (1) The City Council finds that the discharge from roofs, rainspouts, yard drains, surfaces, groundwater, sump pumps, footing tiles or swimming pools, foundation drains, yard fountains, ponds, cistern overflows, water discharged from any nonresidential air conditioning unit or system, or other means of transmitting natural precipitation and surface waters, collectively referred to as excess infiltration and inflow, into the sanitary sewer system, will and has in the past overloaded the sanitary sewer system. The City Council, therefore, finds it essential for compliance with mandated City Code requirements that the provisions of this section be strictly enforced.
