SIGNIFICANCE OF PROJECT: The Willamette Water Supply System Commission’s goal is to provide a stable and seismically resilient water supply for ratepayers in Washington County. The cities of Hillsboro and Beaverton, along with the Tualatin Valley Water District, have come together to build more than 30 miles of large-diameter pipelines, expand the existing raw water facility, and modify an intake on the Willamette River near Wilsonville, a new raw water filtration facility near Sherwood and water reservoirs on Cooper Mountain.

James W. Fowler Co., serving as the trenchless subcontractor for general contractor Kiewit, is constructing a 270-foot pipe ram of 84-inch-diameter steel pipe underneath Arrowhead Creek, the 55-foot-diameter by 54-foot-deep secant pile launch shaft and 25-foot-diameter by 45-foot-deep secant pile reception shaft, 500 feet of 66-inch welded steel pipe, approximately 1,000 feet of underground utilities, tie-in to the existing pipeline, cleaning and pressure-testing of the pipelines, and other miscellaneous items to complete the pipeline installation. The pipe ram was completed below the water table in cobble- and boulder-laden ground using specialized equipment.

Construction and then operations were expected to create more than 4,000 jobs.

The Tualatin Valley Water District on Nov. 19 will host an outreach event for vendors, subcontractors and suppliers interested in possibly working on the Willamette Water Supply System Raw Water Facilities project.

The existing raw water pump station and intake infrastructure at the Willamette River Water Treatment Plant in Wilsonville will be modified. Work is part of a larger plan to expand the treatment plant in order to supply water to much of the west side of the Portland-metro area.

The event is set for 10 a.m. at Tualatin Valley Water District offices at 1850 S.W. 170th Ave. in Beaverton.

Design consultant Black & Veatch is expected to finish project design in early 2020.

Kiewit Infrastructure West Co., the construction manager/general contractor for the project, is working with Black & Veatch to finalize a procurement plan for a guaranteed maximum price. This will include various work packages containing opportunities for qualified businesses to bid competitively. Kiewit intends to begin advertising upcoming bid opportunities in early 2020 in line with design completion.

Currently, the project team is reaching out to vendors, subcontractors and suppliers about timing and scope for the upcoming Raw Water Facilities project.
