Hillsboro has multiple water providers: Joint Water Commission and Hillsboro Water. This page provides information about Hillsboro Water.

The City of Hillsboro Water, a public community water system under the local government, supplies water to about 88,243 residents living in Hillsboro, which is the county seat of Washington County and the fifth-largest city in the U.S. state of Oregon. Founded in 1876, the City of Hillsboro Water System currently obtains its supply from various sources: purchased surface water from the Joint Water Commission (JWC) Water Treatment Plant located in Forest Grove. During winter, the only source is the Upper Tualatin River, a river that stretches almost 80 miles from the Tillamook State Forest in Washington County to the Willamette River near West Linn. During summer, these two reservoirs supplement the supply: Barney Reservoir, located in the Trask River Watershed, and Scoggins Reservoir, also known as Hagg Lake, located near Gaston.
