Oregon Water Treatment Plant Includes New Seismic Upgrades
Oregon's Willamette Water Supply System Commission has awarded Tempe, Ariz.-based Sundt Construction a construction manager at-risk contract for its $405-million new water treatment plant in Sherwood that will include major seismic upgrades and is part of an estimated $1.6-billion program to augment regional water supply.
The partnership between the Tualatin Valley Water District and the Cities of Hillsboro and Beaverton says construction on the plant, set to initially treat 60 million gallons of water per day with future potential for twice that capacity, began last month. The facility is slated to begin delivering water to customers in 2026.
A critical factor in the design of the plant involved seismic resilience. The 30-acre project site is near the Cascadia subduction zone, an active fault line off the Pacific coast shoreline between northern California and British Columbia.
