Factors Determining Water Rate Amounts

Three main factors determine Hillsboro’s drinking water rate amounts:

Protecting Public Health

Before reaching customers’ taps, water is thoroughly filtered and treated to remove particles, viruses, bacteria, organisms, and viruses including COVID-19.

Additional Water Supply

Hillsboro is partnering with the Tualatin Valley Water District and City of Beaverton to develop the Willamette River at Wilsonville as an additional water source for customers by 2026. Learn more at OurReliableWater.org.

Maintaining Essential Infrastructure

Hillsboro Water strategically upgrades, repairs, and in some cases replaces aging parts of the water system to deliver safe, reliable drinking water to customers.
