(a) No unauthorized person shall uncover, make any connection with or opening into, use, alter or disturb any Municipal sewer or appurtenance thereof without first obtaining a plumbing permit from the Building Department and a street opening permit, where applicable, from the Public Works Department.
(b) Any person desiring sewer service from the Municipal sewer system for premises not theretofore connected with the system shall apply to the Building Department for a plumbing permit. The plumbing permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the Building Commissioner.
(c) All costs and expenses incidental 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.
(d) A separate and independent building sewer shall be provided for every building; except under exceptional circumstances the Building Commissioner may waive the provisions of this subsection.
(e) Old building sewers may be used in connection with new buildings only when they are found, on examination and testing to meet all requirements of City codes and ordinances .
(f) The alignment and materials of construction of building sewers, 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.
(g) The size and slope of the building sewer shall be subject to the approval of the City Engineer but in no event shall the diameter be less than four inches. The slope of such four-inch pipe shall not be less than one-fourth inch per foot. It shall be required that the service stub or wye connection and the building drain shall be uncovered and the differential elevation be determined before construction is begun. Where practicable, the building connection shall be laid on a uniform grade between those two points.
(h) 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 and within three feet of any bearing wall, which might thereby be weakened. The depth shall be sufficient to afford protection from frost. The building sewer shall be laid at uniform grade and in straight alignment insofar as possible. Changes in direction shall be made only with properly curved pipe and fittings.
(i) In all buildings in which any building drain is too low to permit gravity flow to the Municipal sewer, wastewater carried by such drain shall be lifted by approved artificial means and discharged to the building sewer.
(j) 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.
(k) All building sewer connections shall be made to the wye or riser provided for that purpose. If wye or riser is not available, connection shall be made suitable to the City Engineer.
(l) The applicant for the building sewer permit shall notify the Building Commissioner when the building sewer is ready for inspection and connection to the Municipal sewer. The connection shall be made under the supervision of the Director of Public Works or his representative.
(m) All excavations for building sewer installations 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 by the person making the installation.
