All such connections shall be made gastight and watertight. Any deviation from the prescribed procedures and materials must be approved by the Plumbing Inspector before installation.
(3) The person making the connection shall make an opening in the main sewer a similar to the interior diameter of the “Y” branch and then properly cement and attach a saddle in place. The saddle shall have a suitable curvature to conform to the outside diameter of the public sewer.
(B) 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 building and plumbing code, or other applicable rules and regulations of the city. In the absence of code provisions or in amplification thereof, the materials and procedures set forth in appropriate specifications of the A.S.T.M. and W.P.C.F. Manual of Practice No. 9 and the latest edition of the Standard Specifications for Water and Sewer Main Construction in Illinois shall apply.
(C) 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 such building drain shall be lifted by an approved means and discharged to the building sewer.
(D) No person 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.
(E) The applicant for the building sewer permit shall notify the Plumbing Inspector when the building sewer is ready for inspection and connection to the public sewer. Each and every part of a sewer connection shall be inspected and approved by the Waterworks Superintendent or his representative before being concealed or backfilled.
(F) Any person filling in an excavation without having first received the written approval of the Superintendent or Building Inspector as provided in this subchapter, shall, in addition to suffering the fine herein imposed, expose the sewer for inspection by the Superintendent or Building Inspector at no cost to the city. In any case where the Inspector finds the work on any sewer not done in a satisfactory manner as herein provided, he shall serve written notice on the person to whom the permit is issued, stating wherein such work is deficient, and ordering said person to remedy such defect within 24 hours. In the event such person fails to comply therewith, the Inspector shall cause such defect to be corrected at the expense of the person to whom the permit was issued. The sum of $25 as herein provided shall be paid to the City Clerk as a fee for the performance of the Inspector, and it shall be the duty of the Inspector to inspect any sewer connection or sewer pipe within the city. It shall also be the duty of said Inspector to inform the approving authority of any violation of this section, and to assist in the prosecution of offenders.
(G) All excavations for building sewer installation shall comply with the provisions of this code relating to excavations in streets and 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.
