SE Ivon Street Sewer Extension

Sewer and Stormwater
Active
Environmental Services is designing a project to extend the public sewer 180 feet into SE Ivon Street between SE 12th and SE 14th avenues. This will resolve nonconforming sewer connections and provide properties independent connections to the public sewer.
Construction is anticipated to begin in March of 2024 and take up to five months to complete.

This work is part of the City of Portland’s effort to extend the sewer system to properties without direct access to the public sewer and bring them into compliance with City plumbing codes. The project will help protect public health, property, and the environment by increasing the capacity of the public sewer system, reducing the risk of basement sewer backups, and reducing the likelihood of emergency maintenance work in the future.

What’s Happening Now 

Environmental Services’ Nonconforming Sewer Program staff will be contacting property owners whose nonconforming sewer connections will be addressed by this project. The construction of new sewer service lateral pipes will provide those properties a direct connection to the public sewer extension. Learn more about nonconforming sewer connections.

Over the next few months, you may see crews in the project area conducting field investigations. The information they gather will help engineers design the public sewer extension and new service laterals. Activities may include inspecting sewer pipes and maintenance holes, locating underground utilities and marking them with paint or small flags, surveying the land and taking measurements, and drilling holes in the street to collect soil and pavement samples.

You may also see survey crews standing on the sidewalk and street in front of properties in the project area to measure the elevations of the first floors of houses and see if they have basements. They may need to step onto your property briefly. This is necessary to obtain measurements of private sewer depths and will help engineers design sewer improvements to maximize gravity service. 

Construction Methods 

The contractor will use open trench excavation to construct the public sewer extension and service laterals. Open trench excavation is the traditional method of sewer construction and the most common method for installing a new sewer pipe. It consists of digging down to the required depth, installing a new pipe, and then backfilling the trench. 

What to Expect During Construction

It is too soon to know exactly what traffic controls will be necessary to set up a safe work zone and construct the sewer improvements. The contractor will aim to keep SE Ivon Street open for local access. Learn more about what to expect during construction.
