(A) No unauthorized person shall uncover, make any connections with or opening into; use; alter; or disturb any public sewer or appurtenance thereof without first obtaining a written permit from the city or its authorized representative.
(B) All disposal by any person into the sewer system is unlawful except those discharges in compliance with federal standards promulgated pursuant to the Solid Waste Disposal Act, being 42 U.S.C. §§ 6901 et seq. and more stringent state and local standards.
(C) (1) There shall be two classes of building sewer permits:
(a) For residential and commercial service; and
(b) For service to establishments producing industrial wastes.
(2) In either case, the owner or his or her agent shall make application on a special form furnished by the City Council. The permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the City Council. The industry, as a condition of permit authorization, must provide information describing its waste water constituents, characteristics and type of activity.
(D) A building sewer permit will only be issued and a sewer connection shall only be allowed if it can be demonstrated that the downstream sewerage facilities, including sewers, pump stations and waste water treatment facilities, have sufficient reserve capacity to adequately and efficiently handle the additional anticipated waste load.
(E) All costs and expense incident to the installation and connection of the building sewer shall be borne by the owner. The owner shall indemnify the city from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.
(F) A separate and independent building sewer shall be provided for every building, except that where one building stands at the rear of another on an interior lot and no private sewer is available or can be constructed to the rear building through an adjoining alley, court, yard or driveway, the building sewer from the front building may be extended to the rear building and the whole considered as one building sewer.
(G) Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the city, to meet all requirements of this chapter.
(H) The size, slope, alignment, materials of construction of a building sewer, and the methods to be used in excavating, placing of the pipe, jointing, testing and backfilling the trench, shall all conform to the requirements of the rules and regulations of the City Council. In the absence of code provisions or in amplification thereof, the materials and procedures set forth in appropriate specifications of the American Society of Testing Materials, Water Pollution Control Federation Manual of Practice No. 9, the City Engineer’s Specifications for Water and Sewer Main Construction in Minnesota shall apply.
(I) Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor, in all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by the building drain shall be lifted by a means which is approved in accordance with division (H) above, and discharged to the building sewer.
(J) No person(s) shall make connection of roof downspouts, exterior foundation drains, areaway drains or other sources of surface runoff or groundwater to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer.
(K) The connection of the building sewer into the public sewer shall conform to the requirements and applicable rules and regulations of the City Council, or the procedures set forth in appropriate specifications of the American Society of Testing Materials, Water Pollution Control Federation Manual of Practice No. 9 and City Engineer’s Specifications for Water and Sewer Main Construction in Minnesota. All connections shall be made gas-tight and water-tight.
(L) All excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the city.
