Clean Water Services is responsible for sanitary sewer service and storm and surface water management throughout urban Washington County under the Oregon Revised Statutes Chapter 451. These responsibilities include reviewing and issuing permits for erosion control, construction, modification or connection to the public sanitary and surface water management systems, and issuance of water quality sensitive area permits.

The requirements of Clean Water Services' Design and Construction Standards apply to all development within the service area. Through intergovernmental agreements with the larger cities within the service area, Clean Water Services allows the large cities within its service area—Beaverton, Cornelius, Forest Grove, Hillsboro, Sherwood, Tigard, and Tualatin—to issue permits within their city limits.

Through a Memorandum of Agreement with the Oregon Department of Environmental Quality (DEQ), Clean Water Services and its member cities are also permitting agents for the DEQ 1200-C Erosion Control Permits.

Clean Water Services is also required under the Environmental Protection Agency (EPA) to regulate discharges of non-domestic wastewater into the public sanitary sewer system within its service area. All Industrial Waste Dischargers must obtain an Industrial Waste Permit from Clean Water Services prior to discharge. For more information call us at

Clean Water Services is the first in the nation to receive a Watershed-Based Waste Discharge Permit (PDF, 302KB). You can learn more (PDF, 65KB) with our Watershed-Based Waste Discharge Permit overview. Four individual permits for the operation of publicly owned sewage treatment works (POTWs), one municipal separate storm sewage system (MS4) permit and individual storm water permits for the Durham and Rock Creek Advanced Wastewater Treatment Facilities in the Tualatin River watershed have been integrated and consolidated into this document. This represents a change in the traditional approach to regulatory management of the watershed by integrating several program elements of the Clean Water Act into a single document along with water quality trading. This combination allows 1) greater coordination of watershed protection and enhancement programs, 2) greater coordination of watershed assessment and monitoring activities, and 3) greater public involvement.
