(a) No unauthorized person shall uncover, make any connection with or opening into, use, alter or disturb any public sewer or appurtenance thereto without first obtaining a permit therefor from the Director of Public Service.
(b) Construction, modification and extension of sanitary and combined sewers are prohibited, unless approved by the Director and the OEPA.
(c) Any connection to a sanitary or combined sewer within the jurisdiction of the Division of Water and Sanitary Sewage shall be subject to all regulations, charges, rates, fees and assessments which are, or may be, established by the City.
(1) All costs and expenses incident to the installation and connection of a building sewer shall be borne by the owner. The owner shall indemnify the City for any loss or damage that may directly or indirectly result from the installation of the building sewer. The owner of property served by a sewer shall be responsible for the operation, cleaning, maintenance, repair and reconstruction of the building sewer from the building to the point of connection with the public sewer.
(2) A separate, independent building sewer shall be provided for each building. However, where one building stands at the rear of another on an interior lot and no private sewer is available or can be constructed as an addition 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 may be considered one building sewer.
(3) Old building sewers may be used in connection with new buildings only when they comply with all of the provisions of this chapter.
(4) The building sewer shall be cast iron soil pipe, ASTM Specification (A74-72) or equal; extra-strength vitrified clay sewer pipe, ASTM Specification (C700-74) or equal; or PSM Polyvinyl Chloride Pipe, ASTM Specification (D3034-SDR35). Joints shall conform to ASTM (D3212) and installation shall conform to ASTM (D2321). 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 the material set forth in this paragraph or of other suitable material approved by the Director. If the building sewer is installed in filled or unstable ground, the building sewer shall be cast iron soil pipe. However, nonmetallic material may be used if it is laid on a suitable concrete bed or cradle approved by the Director. At the owner's expense, all material shall be inspected and tested according to the requirements of the Director.
(5) The size and slope of the building sewer shall be subject to the approval of the Director. A six-inch diameter pipe or larger shall be used from the property line to the connection with the public sewer. A four-inch diameter pipe may be used from the property line to the building. The slope of the six-inch pipe shall be not less than one-eighth of an inch per foot and the slope of the four-inch pipe shall be not less than one-fourth of an inch per foot.
(6) No building sewer shall be laid parallel to and within three feet of any bearing wall which might 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 so far as possible. Changes in direction shall be made only with properly curved pipe fittings. Pipe bends shall not exceed forty-five degrees.
(7) In all buildings in which any building drain is too low permit gravity flow to the public sewer, sanitary sewage carried by the drain shall be lifted by approved artificial means and discharged to the building sewer.
(8) All excavations required for the installation of the building sewer shall be open trench work, unless otherwise approved by the Director. Pipe laying and backfill shall be performed according to ASTM Specifications (C12-77). No backfill shall occur until the work has been inspected.
(9) All joints and connections shall be made gastight and watertight. In general, the joints shall meet the requirements of ASTM Designation C 425, Type III. The contact surfaces shall be smooth, dimensionally correct and provide a seal that meets the infiltration (exfiltration) requirements and that is of a type which prevents possible damage to the joints in handling. No precast or poured joints containing asphalt are permitted. All joints and pipes shall first be approved by the Director before installation.
(10) The connection between the building and the public sewer shall be made at the Y-branch, provided that the Y-branch is available at a suitable location. Where no properly located Y-branch is available, the owner shall, at his or her expense, make a saddle-type connection by cutting a neat hole into the public sewer to receive the building sewer. The invert of the building sewer at the point of connection shall be at or above the spring line of the public sewer. The joint shall be smooth and neat, and the connection shall be made secure and watertight by encasement in concrete. Special fittings may be used for the connection only when approved by the Director.
(11) The applicant for the building sewer permit shall notify the Director when the building sewer is ready for inspection and connection to the public sewer. The connection shall be made by the applicant, under the supervision of the Director or his or her representative.
(12) All excavations for building sewer installations shall be adequately guarded with barricades and lights to protect the public from hazard. A street, sidewalk, parkway or other public property that is disturbed in the course of the work shall be restored in a manner satisfactory to the City.
(13) No person constructing a sanitary sewer or building or house connection shall leave the excavation open, unsealed or incomplete in any fashion which would permit storm, surface or subsurface water to enter the sewer.
