(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 Clerk-Treasurer.
(B) (1) There shall be two classes of building sewer permits:
(a) For residential and commercial service; and
(b) For service to establishments producing industrial waste.
(2) In either case, the owner or his or her agent shall make application on a special form furnished by the town. The permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the Inspector. A permit and inspection fee of $5 for a residential or commercial building sewer permit and $15 for an industrial building sewer permit shall be paid to the Clerk-Treasurer at the time the application is filed.
(C) All costs and expenses incident to the installation and connection of the building sewer shall be borne by the owner. The owner or the person installing the building sewer for the owner shall indemnify the town from any loss or damage that may directly or indirectly be occasioned by the installation.
(D) 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 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 tested by the Inspector to meet all requirements of this chapter.
(F) The building sewer shall be cast iron soil pipe, ASTM specification or equal; vitrified clay sewer pipe, ASTM specification or equal; or other suitable material approved by the Inspector. Joints shall be tight and water-proof. 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 pipes with leaded joints may be required by the Inspector 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 non-metallic material may be accepted if laid on a suitable concrete bed or cradle as approved by the Inspector.
(G) The size and slope of the building sewers shall be subject to the approval of the Inspector, but in no event shall the diameter be less than six inches. The slope of the six-inch pipe shall not be 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 a uniform grade and in straight alignment in so far as possible. Changes in direction shall be made only with proper curved pipes 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 the drains shall be lifted by approved artificial means and discharged to the building sewer. No water-operated sewage ejector shall be used.
(J) All excavations required for the installation of a building sewer shall be open trench work unless otherwise approved by the Inspector. Pipe laying and backfill shall be performed in accordance with ASTM specifications except that no backfill shall be placed until the work has been inspected by the Inspector or his or her representative.
(K) (1) All joints and connections shall be made gas tight and water tight. Cast iron pipe joints shall be firmly packed with oakum or hemp and filled with molten lead, Federal Specification QQ-L-156, not less than one inch deep. Lead shall be run in one pouring and called tight. No paint, varnish or other coatings shall be permitted on the jointing material until after the joint has been tested and approved.
(2) All joints in vitrified clay pipe or between pipe and metals shall be made with approved jointing material in accordance with the latest edition of Volume III, Plumbing Rules and Regulations of the Administrative Building Council of the state.
(3) Other jointing materials and methods may be used only by approval of the Inspector.
(L) The connection of the building sewer into the public sewer shall be made by the "Y" branch, if the branch is available at a suitable location. If the public sewer is 12 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 Inspector. Where the public sewer is greater than 12 inches in diameter, and no properly located "Y" branch is available, a neat hole may be cut in the public sewer to receive the building sewer, with entry in the downstream direction at an angle of about 45 degrees. A 45-degree ell may be used to make the 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 water tight by encasement in concrete. Special fittings may be used for the connection only when approved by the Inspector.
(M) The applicant for the building sewer permit shall notify the Inspector when the building sewer is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the Inspector or his or her representative.
(N) All excavations for building sewer installation shall be adequately guarded with barricades and light 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 town.
