(A) Unauthorized connections. No authorized 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 district.
(B) Classes of permits; applications; fees.
(1) There shall be two classes of building sewer permits:
(a) For residential and commercial service; and
(b) For services 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 district. The application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the district. An application and an inspection fee for a sewer permit shall be paid to the district at the time the application is filed. The prevailing constructing charges for making a tap into the district’s sewer system shall be as determined from time to time by the Board of County Sanitation District. Any person, including industrial users, granted a sewer permit shall be authorized for so long as he or she shall comply with all conditions and requirements set forth in this subchapter. However, if any person, including industrial users, shall have their permit to discharge sewage revoked or terminated pursuant to § 52.41 of this subchapter, then such person shall be required to make application as set forth in this division (B) of this section for another permit and in addition to the requirements set forth in this division (B) of this section shall satisfy the district that all violations which resulted in the termination of its permit have been remedied.
(C) Costs and expenses borne by owner; indemnification of district. All costs and expenses incident to the installation and connection of the building sewer shall be borne by the owner. The owner shall indemnify the district from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.
(D) Separate sewers required. A separate and independent building sewer shall be provided for every building, unless 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, then the building sewer from the front building may be extended to the rear building and the whole considered as one building sewer. The district will not assume any obligation or responsibility for damage caused by or resulting from any such single connection mentioned above. A separate tap on fee will be assessed for each building served.
(E) Use of old building sewers. Old building sewers may be used in connection with new buildings only when they are found on examination and test by the district to meet all requirements of this subchapter.
(F) Pipe specifications. All new building sewers shall be PVC pipe, ASTM D-3034, latest revision, and shall meet requirements of the State Plumbing Code. Joints shall be as set out in division (I) of this section. Any part of the building sewer that is located within five feet of a water service pipe shall be constructed at least one foot deeper in the ground than the water service. The district may require ductile iron pipe in filled or unstable ground, and/or in areas where the cover over the building sewer is less than three feet.
(G) Laying of building sewer; depth. No building sewer shall be laid parallel to within three feet of any bearing wall which might thereby be weakened. The depth shall be sufficient to afford 24 inches of cover over pipe except where exposed to vehicular traffic. Portions of the building sewer subjected to vehicular traffic shall have a minimum cover of 36 inches or be encased in a six-inch envelope of concrete. The building sewer shall be laid at uniform grade and in straight alignment insofar as possible.
(H) Size and slope. The size and slope of the building sewer shall be subject to the approval of the district. In general, the building sewer shall not less than four inches in diameter if constructed for single user. The slope of the building sewer shall in no event be less than one-eighth inch per foot. 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.
(I) Joints and connections. All new joints and connections shall be made gastight and watertight and shall comply with the State Plumbing Code.
(J) Connection to public sewer. The building sewer shall be connected into the public sewer at the curb or property line, if a service branch sewer or wye is available at a suitable location. Where no properly located service branch sewer or wye is available an authorized agent of the district will cut a neat hole into the main line of the public sewer and install a suitable wye or tee saddle and extend a service branch sewer at such a point of connection with a wye saddle shall be in the upper quadrant of the main line of the public sewer. A neat workmanlike connection not extending past the inner surface of the main public sewer will be made and the saddle made secure and watertight.
(K) Elevation. Whenever possible, the building sewer shall be brought to the building at an elevation below the 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 as required by the State Plumbing Code.
(L) Trenches. All excavations required for the installation of a building sewer shall be open trench work unless otherwise approved by the district; and all such trenches shall be kept open until the pipe has been inspected, tested and approved by the District or its agent. Except where bends are supplied, trenches shall be straight in direction and grade to accommodate prefabricated joints. Trenches shall be at least 20 inches wide. Building sanitary sewers laid in undisturbed ground must be laid on at least six inches of pea gravel, sand, #9 stone or other approved grillage to support the pipe. The trench shall be filled with the same approved grillage on each side of the pipe and six inches over the same.
(M) Connection of surface runoff or groundwater to building sewer. No person shall make connection of roof downspouts, exterior foundation drains, areaway drains, sump pumps or other sources of surface runoff or groundwater to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer.
(N) New connections from inflow sources. New connections to the sanitary sewer systems from inflow sources is prohibited, as defined and in satisfaction of the requirements of Regulation No. 35.927.4 promulgated under Title II of the Federal Water Pollution Control Act Amendments of 1972, or any amendment thereof.
(O) Barricading and lighting; restoring excavations. All excavations for building sewer installation shall be adequately guarded by barricades and lights so as to protect the public from hazards. Furthermore, all pertinent and applicable OSHA requirements shall be met. Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the district.
(P) Connection at property line or easement; wye or tee connections. The building sewer shall be connected into the public sewer at the easement or property line. Where no properly located service branch is available, an authorized agent of the district shall cut a neat hole into the main line of the public sewer and a suitable wye or tee saddle installed to receive the building sewer. The invert of the building sewer at such point of connection with a saddle shall be in the upper quadrant of the main line of the public sewer. A neat workmanlike connection not extending past the inner surface of the public sewer shall be made and the saddle made secure and watertight by specially prepared for this purpose. A wye and fitting shall be installed at the property line between the public sewer and the building sewer. This fitting shall serve the purpose of a cleanout and for applying the smoke test during inspection of the line. After the testing, a riser will be inserted in this fitting and brought flush with the ground surface. A stopper or plug, outfitted with a type joint applicable to the pipe used, shall seal this riser against the intrusion of groundwater or surface water.
(Q) Inspections; notification. The applicant for the building sewer permit, or his or her licensed plumber, shall notify the district or its agent when the building sewer is ready for inspection and connection to the public sewer. The inspection shall be made within a reasonable period of time after the receipt of notice. The connection shall be made under the supervision of the district or its agent.
(R) Testing. All building sewers shall be smoke or air tested through the wye and fitting at the public sewer connection, with the public sewer tightly plugged off, after connections at both ends are made and after all pipe is properly bedded and backfilled to the top of pipe. At time of test, any openings into the building drain inside the building shall be water trapped or plugged. Any leakage of smoke from building sewer or building drain and plumbing shall be located at test and repaired to stand repetition of smoke test without leakage. A suitable low-pressure air test may be considered to be equal to smoke testing. All trenches or other excavated areas shall be kept open until the pipe has been tested and approved by the district.
