Lake Oswego, with Portland’s support, has been using a phased project approach to replace the aging Tryon Creek plant with an environmentally sustainable wastewater treatment facility, at a good value to the community. The first phase of the project is now complete, which included developing facility designs, preliminary permitting, and proposed pricing for the Wastewater Treatment Facility Project.
For the second phase of the project, Lake Oswego will explore a competitive procurement method using public financing, to complete the design, construct the facility, and operate and maintain the facility under a long-term contract.
