Request for Proposals for Designing, Building, Operating and Maintaining New Facility
The City of Lake Oswego has issued a Request for Proposals (RFP) to provide integrated design, construction, and long-term operations and maintenance services for the new wastewater treatment facility and associated infrastructure to replace the current Tryon Creek plant.
WIFIA Loan Authorization
On August 5th, the Lake Oswego City Council authorized a loan through the Environmental Protection Agency’s Water Infrastructure Finance & Innovation Act (WIFIA) program. A link to the Council Report is here. This loan provides flexibility to the project’s funding portfolio which also includes utility revenue, cost share payments from the City of Portland, System Development Charges (SDCs), and traditional municipal bonds. The WIFIA loan provides benefits that enable utility rate stability, which has been a point of emphasis for this project.

Next Steps
Once a proposal is selected later this year, the project team plans to hold a meeting to share the final designs with the community and continue land use permitting. Demolition and preliminary construction are expected to start in 2026.
