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.
