Humboldt Sewer Repair

Sign up for email construction updatesUpdated February 10, 2017

Environmental Services has designed three large-scale sewer projects in north and northeast Portland neighborhoods to replace or repair about 73,000 feet of public sewer pipes that are on average 90 years old and deteriorating due to age. That's almost 14 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.

In the Humboldt neighborhood, the work includes repairing over 17,000 feet of public 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 began December 27th, 2016, and will continue for about a year.
