(a) No unauthorized person shall uncover, make connections with or open into, use, alter or disturb any public sewer or appurtenance thereof without first obtaining a written permit therefor from the Service Director.
(b) All costs and expenses incident to the installation and connection of a building sewer shall be borne by the owner of the building. The owner shall indemnify the Authority for 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 each residence or building, except that 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, provided a recorded easement for use and maintenance of this sewer is stated on the application, and the method of installation meets the approval of the Service Director.
(d) Old or existing building sewers may be used in connection with new construction only when they are found, on examination and upon testing by the Service Director, to meet all requirements of this chapter. (Ord. 21-94. Passed 6-28-94.)
(e) The building sewer shall be cast iron soil pipe, ASTM Specification A74-42 or equal, PVC ASTM D3034 or F679 or equal, or other suitable material approved by the Service Director. 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 soil pipe with leaded joints. Cast iron pipe with leaded joints may be required by the Service Director where the building sewer is exposed to damage by tree roots. If the installation is in fill or in unstable ground, the building material may be accepted if laid on a suitable concrete bed or cradle, as approved by the Service Director. (Ord. 16-21. Passed 4-27-21.)
(f) The size and slope of the building sewer shall be subject to the approval of the Service Director, 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-eighth inch per foot.
(g) 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 insofar as possible. Changes in direction shall be made only with properly curved pipe and fittings.
(h) In all buildings in which any building drain is too low to permit gravity flow to the public sewer, wastewater carried by such drain shall be lifted by approved artificial means and discharged to the building sewer.
(i) All excavations required for the installation of a building sewer shall be open trench work unless otherwise approved by the Service Director. Pipe laying and backfill shall be performed in accordance with ASTM Specification C-12-19, except that no backfill shall be placed until the work has been inspected.
(j) All joints and connections shall be made gastight and watertight.
(l) All joints in vitrified clay pipe or between such pipe and metals shall be made with an approved watertight O-ring-type joint.
(2) Cement joints shall be made by packing a closely twisted jute or oakum gasket of suitable size to partly fill the annular space between pipes. The remaining space shall be filled and firmly compacted with mortar composed of one part portland cement and three parts sand. The material shall be mixed dry; only water sufficient to make the mixture workable shall be added. Mortar which has begun to set shall not be used or retempered. Lime, putty or hydrated lime may be substituted to the extent of not more than twenty-five percent of the volume of the Portland cement that may be added.
(3) Only jointing materials and methods that are approved by the Service Director may be used.
(k) The connection of the building sewer into the public sewer shall be made at the wye 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 wye branch is available in the public sewer, the owner shall, at his or her expense, install a wye branch in the public sewer at the location specified by the Service Director. Where the public sewer is greater than twelve inches in diameter and no properly located wye 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 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 Service Director.
(l) An applicant for a building sewer permit shall notify the Service Director when the building sewer is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the Service Director or his or her representative.
(m) All excavations for a building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, driveways, sewers, utilities and other public or private property disturbed in the course of work shall be restored in a manner satisfactory to the Authority.
(n) All sewer mains shall be laid in accordance with the grade established by the Service Director.
(o) All main sewers shall be provided with manholes, which manholes shall not be more than 375 feet apart. All manhole covers shall be provided with proper holes for ventilation of gases or fumes.
(p) The entrance of the sewer to all manholes shall be at the bottom thereof and no sewer shall be cut into any manhole, whether now established or hereafter constructed, except as above provided.
(q) Foundation drains, roof downspouts, area drains or other sources of surface runoff shall not be connected, either directly or indirectly, to building sewer or public sewer. If any drains are installed carrying surface or subsurface water, they shall be constructed to carry said water to a street or to a natural watercourse.
