N Commercial and N Shaver Sewer Repair Project

Project Overview

City of Portland Environmental Services – your sewer and stormwater utility - is designing a project to replace and construct nearly 750 feet of sewer pipe in your neighborhood. Heavy tree roots have grown into and are clogging and damaging the 102-year-old pipe. This sewer repair project will protect public health and the environment by reducing the possibility of costly breaks, sink holes and sewage releases to homes, businesses and streets. 

N Commercial / N Shaver Sewer Repair Project

Design Changes

In addition to repairing nearly 400 feet of sewer pipe that runs through Unthank Park, an additional 250 feet of new diversion pipe will be constructed on N Mason St between N Kerby and N Commercial Ave to divert stormwater flow.

Schedule

Environmental Services has completed the design of the project and is currently in the bidding process to select a contractor for construction. Construction is anticipated to start this summer.

Construction Methods

Environmental Services has selected both trenchless and open trench excavation methods for this project. Learn more about these methods at www.portlandoregon.gov/bes/methods.
