For several years, the City of Portland worked to stop sewer overflows to South Ash Creek during wet weather. In 2006, the City installed a temporary bypass pipe on the surface near the creek to prevent overflows. Beginning in October, 2013 crews from Emery & Sons repaired portions of the sewer, removed the temporary pipe and installed a permanent sewer line to improve sewer system reliability and stop wet weather overflows to the creek. The work on this project involved the installation of cured-in-place-pipe lining in approximately 1,321 feet of existing 8-inch pipe, 331 feet of 10-inch pipe and 382 feet of 12-inch pipe. Other work included the installation of 359 feet of 15-inch PVC pipe, installation of three new manholes, rehabilitation existing manholes by use of a spray-on liner, and removal of 710 feet of existing bypass pipes.
