Lake Oswego/Tigard Water

Lake Oswego/Tigard Water Partnership Water Treatment Plant
The new treatment plant will produce high-quality drinking water using ozone technology to assure a reliable and consistent supply of water for thousands of customers in Lake Oswego and Tigard. The treatment plant design incorporates energy efficiency, renewable energy components, and sustainable operational practices. The new plant will be better able to withstand large seismic events, and a tie-in with the City of West Linn’s system will allow the new treatment plant to serve as a back-up water source for West Linn.
