Project Overview

Environmental Services has completed design work and will begin construction in summer 2017 for an inner southeast Portland repair of a deep interceptor sewer line that is deteriorating due to age. The repairs will extend the life of the sewer and protect public health, water quality and the environment. The city built the large-diameter Southeast Interceptor in 1954. It runs parallel to the Willamette River under inner southeast neighborhoods and is between 5 to 6 feet wide and 25 to 54 feet below the surface.

Schedule

Construction is currently anticipated to begin as early as June or July 2017 and continue for up to a year.

For traffic safety and to minimize traffic congestion, the city will do night work at all but one of the project work zones. See map for details.

Portland noise code allows construction from 7 a.m. to 6 p.m. Monday through Saturday. Work after 6 p.m. and before 7 a.m. and all hours on Sundays requires a noise variance from the Portland Noise Office. Because construction crews will work past 6 p.m. and on weekends, Environmental Services applied for and was granted a Noise Variance.
