9-2-5: BUILDING SEWERS AND CONNECTIONS:
   A.   Permit To Connect:
      1.   Permit Required: 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 Superintendent.
      2.   Classes Of Permits; Applications: There shall be two (2) classes of building sewer permits: a) for residential and commercial service; and b) for service to establishments producing industrial wastes. In either case, the owner or his agent shall make application on a special form furnished by the City, and by the district in the case of industrial wastes. The permit application shall be supplemented by any plans, specifications, or other information considered pertinent in the judgment of the building official. (Ord. 81-O-8, 6-5-1981)
      3.   Permit And Inspection Fee: A permit and inspection fee as provided in section 3-2A-1 of this Code shall be paid to the City at the time the application is filed. Each industry, as a condition of permit authorization, must provide information describing its wastewater constituents, characteristics, and type of activity. (Ord. 81-O-8, 6-5-1981; amd. 2009 Code)
      4.   Conditions Of Permit: 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 works, including sewers, pump stations and wastewater treatment facilities, have sufficient reserve capacity to adequately and efficiently handle the additional anticipated waste load.
   B.   Separate Building Sewers: A separate and independent building sewer shall be provided for every building; except, 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 of the 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.
   C.   Use Of Old Building Sewers: Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the Superintendent, to meet all requirements of this chapter.
   D.   Installation And Connection Requirements:
      1.   The building sewer shall be extra strength vitrified clay pipe and fittings conforming to ASTM specification C700 with compression type joints conforming to ASTM specification C425, or extra heavy cast iron soil pipe and fittings conforming to CISPI specification HS-67 with compression type rubber gasket joints conforming to ASTM specification C564, or other suitable materials approved by the Superintendent.
      2.   The building sewer shall not be less than six inch (6") diameter size pipe, installed at a minimum invert slope of one- eighth inch (1/8") per foot, or not less than four inch (4") diameter size pipe in length of not less than ten feet (10'), installed at a minimum invert slope of one-fourth inch (1/4") per foot. Building sewers shall be constructed in accordance with the requirements of the Superintendent as to trench excavation and backfilling, installation of pipe and fittings and testing.
      3.   The connection of the building sewer into the public sewer shall be made at the Y branch, if such branch is available at a suitable location. If the public sewer is twelve inches (12") in diameter or less and no properly located Y branch is available, the owner shall, at his expense, install a Y branch in the public sewer at the location specified and installation approved by the Superintendent. Where the public sewer is greater than twelve inches (12") in diameter and no properly located Y branch is available, a neat hole may be cut into the public sewer to receive the building sewer, with entry in the downstream direction at an angle of about forty five degrees (45°). A forty five degree (45°) ell may be used to make such connection, with the spigot end cut so as not to extend past the inner surface of the public sewer. The invert of the building sewer at the point of connection shall be at the same or a higher elevation than the invert of the public sewer. A smooth, neat joint shall be made and the connection made secure and watertight by encasement in concrete. Special fittings may be used for the connection when approved by the superintendent.
      4.   The building sewer pipe shall be bedded on a layer of gravel or crushed stone conforming to ASTM no. 67 specifications and shall have a minimum thickness of four inches (4") under the pipe barrel and two inches (2") under the bells. It shall be carefully placed and compacted around the pipe to provide uniform support to the bottom quadrant.
      5.   Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. No building sewer shall be laid parallel to or within three feet (3') of any bearing wall which might thereby be weakened. The depth shall be sufficient to afford protection from frost. In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sewage carried by such drains shall be lifted by approved pumping devices and discharged to the building sewer.
      6.   In structures with crawl spaces or on slabs, a cleanout Y (wye) at the outside wall is required to be installed.
      7.   All excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazards. Streets, sidewalks, parkways, and other property disturbed in the course of the work shall be restored in a manner satisfactory to the city. Prior to any excavation, the plumber or sewer contractor shall notify all public and private utility companies.
   E.   Prohibited Discharges:
      1.   No person shall make connection of roof downspouts, exterior foundation drains, areaway drains, or other sources of surface runoff or ground water to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer.
      2.   It shall be unlawful to discharge wastewater to any public sanitary sewer except those wastewaters in compliance with standards promulgated pursuant to the federal act, or the state environmental protection act, or any rules, regulations ordinances or standards of the city and/or the district.
   F.   Inspections: The applicant for the building sewer permit shall notify the superintendent when the building sewer is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the superintendent.
   G.   Liability For Costs And Expenses; Bond And Insurance Required:
      1.   All costs and expenses incident to the installation and connection of the building sewer shall be borne by the owner.
      2.   The person installing the building sewer for said owner shall be a plumber or sewer contractor, and he shall indemnify the village from any loss or damage that may directly or indirectly be occasioned by said installation.
      3.   Before a building sewer permit is issued, the plumber or sewer contractor shall file with the city clerk an indemnity bond in the amount of ten thousand dollars ($10,000.00), with corporate surety licensed to do business in the state of Illinois, on bond form supplied by the city. In addition thereto, the plumber or sewer contractor shall file with the city clerk a certificate of insurance covering public liability in the amount of one hundred thousand dollars/three hundred thousand dollars ($100,000.00/$300,000.00) for bodily injury and fifty thousand dollars ($50,000.00) covering property damage.
