EPA Announces $123 Million WIFIA Loan to Lake Oswego for the Project
On September 9, 2025, the City of Lake Oswego closed (executed) a $123 million loan from the US Environmental Protection Agency for the Wastewater Treatment Facility project through the Water Infrastructure Finance & Innovation Act (WIFIA) program.
EPA’s announcement shared: “This project will help the city modernize its wastewater infrastructure by constructing a new wastewater treatment facility to replace its existing 60-year-old plant. The new facility will be compliant with current structural code, mitigating impacts from seismic activity. Overall, this project improves the city’s wastewater services and reduces the risk of untreated wastewater spilling into the Willamette River.”
“Deferring principal payments for five years allows the City of Lake Oswego to more slowly and uniformly raise customer sewer rates, compared to a larger and more immediate rate increase of approximately 20 percent without WIFIA financing.”
