Your clean water utility
Clean Water Services (PDF, 201KB) is a water resources management utility in the Tualatin River Watershed. More than 551,000 customers enjoy clean water and healthy rivers and streams through innovative wastewater and stormwater services, flood management projects, water quality and stream enhancement projects, fish habitat protection, and more. Our services are crucial to the region's public health, environmental protection, and economic vitality. Clean Water Services operates four wastewater treatment plants and 40 pump stations. We also work with our 12 member cities to build and maintain the public sanitary sewer and surface water management system. In 1970, Clean Water Services was formed as the Unified Sewerage Agency of Washington County by a 2-to-1 vote of the people to address serious health and pollution problems in the Tualatin River and its tributaries. We met that challenge by unifying 26 inefficient wastewater treatment plants into one coordinated system.
In 2001, Clean Water Services changed its name from the Unified Sewerage Agency to reflect our broader role in managing water resources. Today we work to improve water quality in our local streams, manage flooding, protect fish habitat, manage flow in the Tualatin River, and operate four award-winning wastewater treatment facilities. Our nationally recognized work in water resource management is an investment in clean and thriving waterways.
Although Clean Water Services maintains a close working relationship with Washington County government, we are a special service district that serves as a separately managed and financed public utility. Our Board of Directors is comprised of the individuals who are elected as Washington County Commissioners:
- Andy Duyck Chairman (at large)
- Dick Schouten (District 1)
- Greg Malinowski (District 2)
- Roy Rogers (District 3)
- Bob Terry (District 4)
Our internal leadership team:
- Bill Gaffi, General Manager
- Diane Taniguchi-Dennis, Deputy General Manager
- Mark Poling, Business Services Department Director
- Nora Curtis, Conveyance Systems Department Director
- Nate Cullen, Wastewater Treatment Department Director
- Ken Williamson, Regulatory Affairs Department Director
- Bruce Roll, Watershed Management Department Director
- Jerry Linder, Chief Legal Counsel
- Mark Jockers, Government and Public Affairs Manager
- Mat Stickler, Information Technology Division Manager
- Kathy Leader, Finance Manager
The purpose of the Clean Water Advisory Commission (CWAC) is to review and discuss major policy issues and programs related to the management of water resources in the Tualatin River Watershed and make recommendations to Clean Water Services' Board of Directors.

Clean water and healthy rivers and streams are a source of community pride. Working in partnership with our 12 member cities (PDF, 298KB)—Beaverton, Tigard, Tualatin, Hillsboro, King City, Forest Grove, Sherwood, Cornelius, Banks, Gaston, Durham, and North Plains—we protect these resources by serving as your wastewater and stormwater utility. Although Clean Water Services maintains a close working relationship with Washington County government, we are a special service district that serves as a separately managed and financed public utility.
Through our wastewater utility, we clean more than 64 million gallons of wastewater a day to among the highest standards in the nation before returning the water to the Tualatin River.
Our Surface Water Management (SWM) utility manages flooding and pollution, and protects fish habitat. We maintain storm drain pipelines and ditches, sweep streets, and construct flood management and water quality projects.
The District also operates the Clean Water Institute, a non-profit which provides the District with the ability to consider new national and international business opportunities, influence ecological restoration on a larger scale, and provide value to our ratepayers.
Protecting public health and the Tualatin River is at the heart of our work. The 80-mile-long Tualatin River is unlike most rivers in the Northwest. It meanders slowly through relatively flat terrain, draining more than 700 square-miles of forested, agricultural and urban areas before joining the Willamette River. The Tualatin is Washington County's only river and an important resource to the region. The river is used for regional drinking water supply and agricultural irrigation. In addition, canoeing, fishing, and wildlife viewing draw thousands of outdoor enthusiasts each year.
