Humboldt Sewer Repair

Environmental Services is designing three large-scale sewer projects in north and northeast Portland neighborhoods to replace or repair about 91,000 feet of public sewer pipes that are on average 90 years old and deteriorating due to age. That's more than 17 miles of sewer pipes. The three adjacent project areas will include construction in the Piedmont, Humboldt, Woodlawn and King neighborhoods plus a few blocks in Overlook and Arbor Lodge.

Humboldt project at a glanceIn the Humboldt neighborhood, the work will include repairing over 17,000 feet of sewer pipes. The project will improve sewer and stormwater infrastructure, increase sewer capacity, and reduce the risks of street flooding and sewage releases to homes, businesses and streets.

Construction in Humboldt, plus a few blocks in Overlook and Arbor Lodge, will begin in fall 2016 and continue for a year.
