Concordia Sewer Repair Project

Button. Click to sign up for email updatesEnvironmental Services is designing a large-scale sewer project in the Concordia neighborhood in North Portland to replace or repair approximately 14,300 feet of public sewer pipes that are 80 to 100 years old and deteriorating due to age. The work will include some manhole and storm drain replacement and new public sewer connections for private properties where necessary. The sewer repairs will improve sewer and stormwater infrastructure, increase sewer capacity, and reduce the risks of street flooding and sewage releases to homes, businesses and streets.

Design will continue through 2017. Construction is anticipated to begin in early 2018.

What's Happening Now?Survey color markings

Over the next several months, crews will be locating utilities, surveying, inspecting sewer pipes and manholes with closed circuit TV, and drilling to take soil and pavement samples. These activities occur over time, rather than all at once, and will help engineers determine the appropriate construction method at each location.
