Status of the Project

Lake Oswego, with Portland’s support, has been using a phased project approach to replace the aging Tryon Creek plant with an environmentally sustainable wastewater treatment facility, at a good value to the community.

The first phase of the project is now complete, which included developing facility designs, preliminary permitting, and proposed pricing for the Wastewater Treatment Facility Project.

This first phase successfully demonstrated the feasibility of building a new plant away from the riverfront. It also enabled the cities to make a fully-informed decision about the costs and benefits associated with the private-public partnership approach to constructing the project.

Upcoming Council Meeting 1/30

On Tuesday, January 30, 2024, at 4:30 p.m. Lake Oswego City Council will consider the next phase – whether to enter a 30-year agreement with EPCOR to design, build, finance, operate, and maintain a new wastewater treatment facility; or to explore other options, such as a competitive procurement method using public financing, to complete the design, construct the facility, and operate and maintain the facility under a long-term contract.

Here is a link to the council report and the agenda. You can view this meeting livestreamed on the City’s YouTube channel.

Website Changes
