Slayden partnered with the City of Lebanon to replace its aging water treatment plant with a modern, reliable facility built to support the community for generations. Nestled along the South Santiam River, the new system includes a thoughtfully designed river intake, raw water pump station, and full treatment plant all connected by upgraded raw water, sewer, and stormwater pipelines. The plant now delivers 4.5 MGD of clean drinking water, with room to expand to 8 MGD as the community continues to grow.
At the heart of the project is a 14,000 SF pre engineered metal building that houses a state of the art membrane filtration system, chemical treatment processes, feed and finished water pumps, electrical systems, and welcoming administrative spaces. The site also features a new concrete settling basin and two glass fused to steel storage tanks, providing 25,000 gallons of raw water capacity and more than 430,000 gallons of finished water storage. The completed facility reflects the City’s forward thinking approach to water resources and Slayden’s commitment to building dependable, long lasting infrastructure for Pacific Northwest communities.
Slayden earned First Place in the 2025 AGC Construction Safety Excellence Awards (CSEA) in the Utility Infrastructure Category — Under 500,000 Work Hours.
