Updated September 19, 2017

Design is complete on an Environmental Services sewer replacement project in the Slabtown district in northwest Portland (see map below). The project will increase sewer system capacity, strengthen the overall system, and protect water quality and the environment.

Project Scope and Schedule

This project will replace and upsize the public sewers in streets, repair laterals that connect properties to the sewer system, replace stormwater inlets and inlet pipes, and repair several manholes throughout the project area. Construction is expected to begin as soon as November 2017.
