City of Portland – Ash Creek (West of S.W. 57th Ave.) Sanitary Sewer Rehabilitation Project

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.
