(A) The applicant for the building sewer permit shall notify the WWTP Superintendent when the building sewer is ready for connection to the public sewer. The connection shall be made under the supervision of the WWTP Superintendent, or his or her representative. The connections shall be made gas-tight and water-tight and verified by proper testing.
(B) All building sewers shall be air tested through the wye branch at the public sewer connection, with public sewer tightly plugged off, after connections at both ends are made and after all pipe is properly bedded and backfilled at least to top of pipe and if backfill is completed, within two weeks after completion of backfill. CCTV shall also be conducted in order to determine the presence of leaks. At time of test, any openings into the building drain inside the building shall be water trapped or plugged. Any leakage from building sewer or building drain and plumbing shall be located at test by CCTV and repaired to stand repetition of air testing without leakage. Tests shall be performed at the expense of the property owner in the presence of an independent inspector provided by the owner or developer. When testing is completed, the temporary flow line plug shall be removed and a permanent water-tight plug shall be placed in branch of test wye-branch and carefully backfilled by hand and tamped to at least six inches above the top of the branch. All results of air testing and CCTV shall be submitted to the city prior to completion of sewer connection.
