ABOUT THE WILLAMETTE WATER SUPPLY SYSTEM

TVWD and the Cities of Hillsboro and Beaverton are partnering to develop the mid-Willamette River at Wilsonville as an additional water supply source.

The new Willamette Water Supply System, when operational in 2026, will provide a reliable water supply for the region by helping water system operators balance supply during times of drought or other supply interruptions, as well as recover more quickly after a large natural disaster. Planning and construction of this important water project is underway and includes a new water filtration plant, more than 30 miles of water pipelines, and water storage tanks - all built to modern seismic standards.
