The City of Hillsboro owns and operates a municipal water system
that serves nearly 79,900 customers in Washington County, Oregon. The
City's service territory is divided into two main areas - one serving
the City's own municipal territory and another serving more than 600 rural
connections in Washington County, along with wholesale service to the
cities of Gaston and Cornelius and the LA Water Cooperative.
As one of four members of the Joint Water Commission (JWC), the City has partial
ownership in various JWC facilities. These include treatment capacity in the water
treatment plant located south of the City of Forest Grove, and transmission capacity
in the various transmission lines that service not only Hillsboro but the cities
of Forest Grove and Beaverton and the Tualatin Valley Water District, fellow JWC
Raw water, the water collected from rainfall and snow-pack runoff, that feeds
the City's water system is stored in both the Scoggins and Barney Reservoirs. Built
and operated by the Bureau of Reclamation, Scoggins Reservoir can store up to 67,900
acre feet of raw water. A contract with the Bureau provides the City with up to
5,000 acre feet of stored raw water. The J.W. Barney Reservoir can store up to
20,000 acre feet of raw water and is owned and operated by a five member commission.
The Barney Reservoir Joint Ownership Commission (BRJOC) includes the four JWC members
in addition to Clean Water Services. The City of Hillsboro owns 31% or 6,200 acre
feet of raw water in the Barney Reservoir. An acre foot is a unit of measure commonly
used by water providers. One (1) acre foot equates to 325,828 gallons of water.
In addition to their ownership share in the JWC and BRJOC facilities, the City
owns its own slow sand filter plant located along the Tualatin River near Cherry
Grove (and Haines Falls). The water from the slow sand filter plant serves the
City's wholesale customers of Gaston, Cornelius and the LA Water Cooperative, and
provides retail service to more than 600 residents in rural Washington County,
in and around the unincorporated areas known as Dilley, Cherry Grove, and Laurelwood.
The Utilities Commission governs the City's water system as established
Charter. The Commission is comprised of three residents of the City
of Hillsboro and meets on the second Tuesday of each month, at 12:45 p.m.,
