LO Wastewater Treatment Facility Info Session 1 10/13/2021

This was an informational session held by the City of Lake Oswego on October 13, 2021, regarding the wastewater treatment facility project. The meeting focused on the need to upgrade or replace the aging Triion Creek wastewater treatment plant, which is jointly owned and operated by Lake Oswego and the City of Portland. The discussion highlighted the exploration of building a new, state-of-the-art facility using a public-private partnership (P3) with EPCOR Foothills Water Partners to design, build, finance, operate, and maintain the plant. Key procurement-related topics included the progressive P3 approach, preliminary service agreement valued at approximately $7 million (mostly financed by EPCOR), and the selection of advanced treatment technology (aerobic granular sludge by Aquinorita). The project aims to maintain or reduce current wastewater rates while delivering improved environmental and operational benefits. The meeting also covered risk allocation, contract performance incentives, schedule milestones, and community engagement plans. City officials emphasized the importance of affordability, resiliency, and environmental stewardship, with a projected total capital and operating cost around $300 million. No formal votes were taken during this session, but the meeting served to inform the public and gather feedback ahead of future council decisions on contract awards and project advancement.
