Willamette Water Monthly

New Funding Option Makes for a Happier Holiday

Tualatin Valley Water District (TVWD) and City of Hillsboro were selected to apply for a low-cost, long-term federal loan to help finance the Willamette Water Supply System (WWSS) which will lead to millions of dollars of savings for TVWD and City of Hillsboro rate payers. The WWSS is under construction and set to deliver water to customers in 2026.

The new WWSS includes an expanded intake, more than 30 miles of pipelines, water treatment plant, and two water storage tanks. The WWSS will serve 400,000 residents and businesses in Washington County. The $1.2 billion system is being built to the highest seismic safety standard to recover quickly after a major earthquake. To date, 96 percent of all Willamette Water Supply expenditures – over $80 million – have been spent on local employees, goods and services.
