Proposed New Wastewater Treatment Facility - Online Open House

Wednesday, November 9, 2022 - 9:00am to Sunday, December 11, 2022 - 5:00pm

Lake Oswego, with Portland's support, is proposing to build a new, state-of-the-art wastewater treatment facility to replace the aging Tryon Creek Wastewater Treatment Plant. 

Our online open house sharing the 60% design concepts and renderings is now live through December 9! The open house features videos, renderings, a virtual tour, graphics, and frequently asked questions about the proposed new wastewater treatment facility. Check out some of the highlights and share your thoughts from November 9 through December 11.
