§ 51.17  BUILDING SEWERS AND CONNECTIONS.
   (A)   No unauthorized person(s) 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 town.
      (1)   There shall be two classes of building sewer permits:
         (a)    For residential and commercial service; or
         (b)   For service to establishments producing industrial wastes.
      (2)   In either case, the owner(s) 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 judgement of the Mayor.
   (B)   All costs and expenses incidental to the installation and connection of the building sewer shall be borne by the owner(s). The owner(s) shall indemnify the town from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.
   (C)   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, in which case the front building’s sewer may be extended to the rear building’s sewer and the whole considered as one building sewer. The town does not and will not assume any obligation or responsibility for damage caused by or resulting from any such single connection aforementioned.
   (D)   Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the town, to meet all requirements of this chapter.
   (E)   The size, slope, alignment, materials of construction of a building sewer and the methods to be used in excavating, placing of 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 town. In the absence of code provisions or in amplification thereof, the materials and procedures set forth in appropriate specifications of the ASTM and WPCFManual of Practice No. 9 shall apply.
   (F)   Whenever possible, the building sewer should 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 at the user’s expense.
   (G)   No person(s) shall make connection to roof downspouts, foundation drains, areaway drains or other sources of surface runoff or groundwater to a building drain which in turn is connected directly or indirectly to a public sanitary sewer.
   (H)   The connection of the building sewer to the public sewer shall conform to the requirements of the Building and Plumbing Code or other applicable rules and regulations of the town or the procedures set forth in appropriate specifications of the ASTM and the WPCF Manual of Practice No. 9. All such connections shall be made gastight and watertight and be verified by proper testing. Any deviation from the prescribed procedures and materials must be approved by the May or before installation.
   (I)   The applicant for the building sewer permit shall notify the Mayor when the building sewer is ready for inspection and connection to the public sewer. The connection and testing shall be made under the supervision of the Mayor or his or her representative.
   (J)   All excavation 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 manner satisfactory to the town.
   (K)   The town shall charge the applicant a sewer tap fee for which the town will provide the building sewer from the town right-of-way line to the sanitary sewer main. The owner(s) shall be responsible for installation of the building sewer on the owner(s) property to the town’s right-of-way including the connection to the tap provided by the town. Charges for sewer taps shall be determined from time to time by the Board of Commissioners and shall be kept on file for public inspection in the office of the Town Clerk. The connection of the building sewer to the town tap shall be inspected and approved by the Town Building Inspector prior to the owner covering the connections.
