The permit application shall be supplemented by any plans, specifications or other information considered pertinent to the Superintendent’s judgment. The initial hookup to the sewer system shall not require an inspection fee. Those permits applied for after the initial system hookups must be accompanied by a fee set by resolution, which shall be paid to the City Recorder. No permit shall be issued until the connection charge specified in § 51.03 has been paid.
(C) 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 city from any loss or damage that may directly or indirectly be occasioned by the installation.
(D) Old building sewers may be used in connection with new buildings or new building sewers only when they are found, on examination and testing by the Superintendent, to meet all requirements of this chapter and the State Plumbing Code.
(E) The building sewer shall be of cast iron soil pipe conforming to Federal Specification WW-P-401, Class B, rubber ring joints, cement pipe with rubber ring joints conforming to Federal Specification SS-P-331a or no-hub cast iron with neoprene seal at joints. Plastic pipe conforming to state specifications adopted in June, 1969 may be utilized.
(F) Building sewer connections shall be made on the house side of the septic tank to the existing pipe.

Connection of the building sewer to the city sewer at the property line shall be with the approved adapter.
(G) The first fitting at the connection with the public sewer and the building sewer shall be an A.C. cast iron or PVC tee. The tee branch shall extend vertically to within six inches of finished ground surface and shall include a sewer clean out box and the lid shall be used for inserting a test plug for water testing the building sewer and as an auxiliary cleanout. Backfilling around the riser shall be done in such a manner so as not to damage the pipe.
(H) The size and slope of the building sewer shall be subject to the approval of the Superintendent, but in no event shall the diameter be less than three inches. The slope of such three-inch pipe shall not be less than one-quarter inch per foot, unless approved by the Superintendent. In no case shall slope of four-inch pipe be less than one-eighth inch per foot.
(I) Building sewers serving buildings with basements shall, whenever possible, be brought to the building at an elevation below the basement floor.
(J) The building sewer shall be laid at uniform grade and in straight alignment insofar as is possible. Changes in direction shall be made only with curved pipe no greater than 45-degree long radius bends. No 90-degree radius elbows shall be used. All pipe shall be laid on a four-inch granular base of three-fourths minus rock, pea gravel, sand or combination thereof.
(K) In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such drain shall be lifted by approved artificial means and discharged to the building sewer.
(L) All excavations required for the installation of a building sewer shall be open trench work, unless otherwise approved by the Superintendent. Pipelaying and backfill shall be performed in accordance with regulations of the State Department of Environmental Quality.

(M) All joints and connections shall be made gastight and watertight.
(N) The applicant for building sewer permit shall notify the Superintendent when the building sewer is ready for inspection and connection to the public sewer. After final approval and testing of the building sewer by the Superintendent, the owner shall make the final connection to the building drain, as defined in § 51.01, unless otherwise authorized by the Superintendent. A 30-minute internal hydrostatic test will be required on all building sewers before connection is made to the building drain. All water, plugs and other facilities for making the test shall be furnished by the applicant. Minimum head over the top of the pipe shall be two feet, and maximum allowable leakage shall be four gallons per hour per 100 feet.
(O) No plumbing contractors shall be allowed to make connection of private sewers to the sewage works of the city on behalf of any owners of property therein without first posting with the city a bond in the sum of $5,000, indemnifying the city and the inhabitants thereof against any loss or damage which the city or the inhabitants thereof might suffer by reasons of the actions of said contractors in making said connections.
