The City of Beaverton joins the Willamette Water Supply Program!
Willamette Water Supply Program (WWSP) staff and leadership have long worked with Beaverton staff to coordinate the dozens of elements of designing and building the Willamette Water Supply System (WWSS). The City of Beaverton’s involvement in the WWSP has been instrumental in successfully identifying pipeline corridors, coordinating communications, and planning the overall system.
As of July 1, 2019, the City of Beaverton will officially become a part owner of the WWSS, receiving up to five million gallons per day when it is operational in 2026.

City of Beaverton residents and businesses will benefit from this partnership due to:
- Resiliency – The Willamette Water Supply System will provide seismic resiliency and a separate source of drinking water with separate transmission pipeline and water storage facilities.
- Proximity – The pipeline will be constructed near logical City of Beaverton system connection points and high growth areas like South Cooper Mountain.
- Partnership – Washington County public agencies already coordinate and leverage joint opportunities. Joining the Willamette Water Supply Program is one more opportunity for agencies to collaborate better. Sharing four main water supply sources (Willamette River, Clackamas River, Bull Run Watershed, and Tualatin River) of high-quality drinking water is beneficial for the entire region.
- Timing – To successfully plan for water supply availability – agencies must look decades ahead and forecast future demands. The City of Beaverton anticipates that their current water supply will be sufficient through 2045 and ownership in the WWSS supports planned growth.
