Willamette Water Supply System Cornelius Pass Road Pipeline Project: Meet the Contractor/Orenco Woods Nature Park Wildlife Management Plan Stakeholder Event
The meeting will be recorded and available for viewing here.
Background
While the upper-Tualatin River will continue to be Hillsboro’s primary water source, the City of Hillsboro is partnering with the Tualatin Valley Water District (TVWD) and City of Beaverton to develop the Willamette River as an additional water supply by 2026. The two water sources will help meet the water needs of customers in the future.
Construction of the new Willamette Water Supply System (WWSS) is underway, and includes:
- A modified water intake on the Willamette River at Wilsonville.
- A state-of-the-art water treatment plant in Sherwood.
- Water storage tanks in Beaverton.
- More than 30 miles of large-diameter transmission water pipeline from Wilsonville to Hillsboro and Beaverton.
As part of the Cornelius Pass Road Pipeline project, about 900 feet of this pipeline will be constructed in the City of Hillsboro beneath the eastern edge of Orenco Woods Nature Park (OWNP). The need to route the pipeline through a small portion the park was anticipated during park development in 2015. Construction is expected to begin in early 2023 and be completed in fall 2024.
