Hillsboro Wastewater Treatment Facility

The Hillsboro Facility, located at 770 S. First Avenue in Hillsboro, Oregon, provides wastewater treatment for the western region of the City of Hillsboro, the community of North Plains, and the community of Banks. Also serviced are the southeastern portion of the City of Cornelius, and the northwestern portion of the City of Forest Grove. The Hillsboro, Forest Grove, and Rock Creek facilities are connected by pipeline and are operated as three integrated units.
