§ 33.157 PRIVATE SEWER THROUGH BORE.

   (A)   Unless a casing is required by the Engineer, private sewer pipe that cannot be installed by open cut methods shall be bored.

   (B)   When a sewer pipe is to be installed in a bored hole, the hole shall be bored by use of a machine that will cut a true circular bore to the required line and grade. Bored tunnels shall be no more than two inches larger in diameter than the maximum outside diameter of the sewer pipe to be placed therein.

   (C)   When the bore has been completed and before the sewer is installed, the bore shall be inspected and approved by the Engineer. PVC pressure pipe (AWWA C-900, Class 150) shall then be joined and installed through the bore.

   (D)   After the sewer pipe is installed, it shall be given a preliminary air test in the presence of the Engineer (see §§ 33.220 through 33.224), and internally inspected by closed circuit television (see § 33.235).
