Two sixty inch diameter pressure sewer rehabilitation projects were completed in the historic downtown area of Milwaukee, Wisconsin in 2006 and 2007. The first project was 3,600 feet of 60-inch cast iron pressure sewer and the second project was 3,920 feet of 60-inch cast iron pressure sewer. The initial challenges were the trenchless structural reconstruction of a pressure sewer and the size of the pipe, five foot diameter. Additional elements of the reconstruction were the bypassing of the wastewater flows, major traffic control, and the construction of access shafts with the rerouting of the existing underground utilities, cutting into the cast iron pipe, cleaning of the 60” round pipes and 49” × 68” box sewer and the disposal of the removed debris. The required equipment and materials were bought to the site for the “over the hole” procedure. The structural cured in place pipe was installed and was hot water cured in place. The gravity box sewer was epoxy coated and the manholes were lined. Following the approvals, the pipeline was sealed, the shafts were closed and the site restored.
