NW Portland Sewer Extension Project

Updated January 31, 2020sign up for email updates

Environmental Services - the city’s sewer and stormwater utility, is launching a project to add 1,080 linear feet of sewer pipe in NW Portland. This will allow direct access to the sewer system for properties that currently can only receive service through a neighboring property. This is most commonly referred to as a party sewer connection. This project will help protect public health, water quality and our environment.


Construction is anticipated to begin in the summer of 2020 and will be completed in spring of 2021.

NW Portland Sewer Extension Project

What’s Happening Now?

Over the next few months, crews will be in the neighborhood locating utilities, surveying, and drilling to take soil and pavement samples. This information will help engineers decide which locations need repair and what construction methods are best for each location. These information-gathering activities typically occur over time, rather than all at once. For details, visit

Private Improvements in the Right-of-Way

City and contractor work crews will need to access and work in the public right-of-way – specifically between the curb and the edge of the sidewalk up to your property line – in order to construct the new sewer pipes.

Anything belonging to you that is located in the right-of-way may be disturbed by construction, including irrigation systems, hard landscaping (stone, brick, pavers, garden boxes, retaining walls, or other construction materials), soft landscaping (trees, plants, shrubs, flowers, grass, bark, etc.), and other amenities. Please remove any items you wish to keep before crews get there. If the city finds items in the right-of-way that conflict with construction, crews will remove and dispose of the items.

If construction disturbs these kinds of items, the city cannot restore or replace them. However, once construction is complete, they will repair or replace sidewalks and curbs as needed. The city will also replace topsoil and grass seed in the planting strip, and any street trees that were removed.
