PROJECT DESCRIPTION
The Willamette Water Supply System will be jointly implemented by the Tualatin Valley Water
District and the City of Hillsboro to provide both areas additional resilient water supply
capacity. Phase 1 will include intake facilities, over 30 miles of pipes, a water treatment plant,
and two storage reservoirs to serve 400,000 residents and businesses in Washington County.
The $1.3 billion system is being built to the highest seismic safety standard to recover quickly
after a major earthquake. The investments in the system will provide reliable, quality drinking
water for generations to come, and during construction the program is providing fuel for the
local economy.
PROJECT BENEFITS
	Accommodates current and future populations' needs in both areas. TVWD will initially
receive 40 MGD of water and ultimately 59.1 MGD of water and COH will initially
receive 15 million gallons per day (MGD) of water and ultimately 36.2 MGD of water.
	Provides a reliable, diverse water supply that is resilient against natural threats from
earthquakes.
	Uses state-of-the-art treatment processes to protect public health from emerging water
quality issues.
	Saves TVWD's ratepayers $138.4 million and COH's ratepayers $125.5 million from
financing the joint project with WIFIA loans compared to a bond issuances.
