LO Wastewater Treatment Facility Neighborhood Meeting 2/3/22

This was a City of Lake Oswego neighborhood meeting held on February 3, 2022, focused on the proposed new wastewater treatment facility project. City officials and EPCOR representatives presented detailed information about the need to replace the aging Triion Creek wastewater treatment plant, the selection of the Aquinora technology, and the site plans involving acquisition of three adjacent properties. The project is currently at about 30% design completion, with plans to reach 60% design by spring and final design by fall 2022. The meeting covered the alternative procurement process approved by the city council, rate increases required to fund the project, and environmental considerations including floodplain compliance and contamination assessments. Attendees were briefed on the facility's design features, sustainability efforts such as solar panels, and operational capabilities including UV disinfection and seismic resilience. Questions from the public addressed topics such as environmental site assessments, decommissioning of the old plant, intergovernmental agreements with the City of Portland for solids processing, and public access to project documents. The project team emphasized ongoing public engagement and upcoming council decisions related to construction and remediation. No specific contract awards or vendor selections beyond the technology choice were discussed in this meeting.
