(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 Superintendent of Wastewater Treatment.
(Ord. 70-18. Passed 4-7-70.)
(b) There shall be two classes of building sewer permits:
(1) For residential and commercial service; and
(2) For service to establishments producing industrial wastes.
In either case, the owner or his or her agent shall make application on a special form furnished by the Municipality. The permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the Superintendent. A permit and inspection fee as set forth in Chapter 206 of the Administration Code - the General Fee Schedule - shall be paid to the Treasurer at the time the application is filed. (Adopting Ordinance)
(c) All costs and expense incidental to the installation and connection of the building sewer shall be borne by the owner. The owner shall indemnify the Municipality 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 when 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.
(e) 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.
(f) The building sewer shall be cast iron soil pipe, ASTM specification A-74 or equal; vitrified clay sewer pipe, ASTM specification C-13 or equal; or other suitable material approved by the Superintendent. Joints shall be tight and waterproof. Any part of the building sewer that is located within ten feet of a water service pipe shall be constructed of cast iron soil pipe with leaded joints. Cast iron pipe with leaded joints may be required by the Superintendent where the building sewer is exposed to damage by tree roots. If installed in filled or unstable ground, the building sewer shall be of cast iron soil pipe, except that nonmetallic material may be accepted if laid on a suitable concrete bed or cradle as approved by the Superintendent.
(g) The size and slope of the building sewer shall be subject to the approval of the Superintendent, but in no event shall the diameter be less than six inches. The slope of such six- inch pipe shall be not less than one-eighth inch per foot.
(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 or 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 in so far 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 public sewer, sanitary sewage carried by such drain shall be lifted by approved artificial means and discharged to the building sewer.
(j) All excavations required for the installation of a building sewer shall be open trench work unless otherwise approved by the Superintendent. Pipe laying and backfill shall be performed in accordance with ASTM specification C-12 except that no backfill shall be placed until the work has been inspected.
(k) All joints and connections shall be made gastight and watertight.
(1) All joints in vitrified clay pipe or between such pipe and metals shall be made with approved hot-poured jointing material or other acceptable jointing material approved by the Superintendent.
(2) Material for hot-poured joints shall not soften sufficiently to destroy the effectiveness of the joint when subject to a temperature of 160 degrees Fahrenheit, nor be soluble in any of the wastes carried by the drainage system. The joint shall first be caulked tight with jute, hemp or similar approved material.
(l) 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 in diameter or less, and no properly located “Y” branch is available, the owner shall, at his or her expense, install a “Y” branch in the public sewer at the location specified by the Superintendent. Where the public sewer is greater than twelve inches 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. A forty-five degree 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 at 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 only when approved by the Superintendent.
(m) 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 or his or her representative.
(n) 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 Municipality.
