Natural Systems Enhancement & Stewardship

About Natural Systems Enhancement & Stewardship

In 2020, the Watershed Management Department changed its name to Natural Systems Enhancement & Stewardship (NSES) to better reflect the work of the department. Natural systems refers to the connected, interdependent ecosystems in and out of the Tualatin Basin — upland, riparian, floodplain, wetland and instream. The new department name refers to our proactive and innovative role working across all the ecosystems to protect our watershed and keep it healthy and resilient. Stewardship refers to the community network needed to protect these assets for future generations. As before, NSES continues to build and strengthen innovative and resilient partnerships to enhance the benefits that natural resources provide to the community.

In 2005, Clean Water Services was given the opportunity to meet regulatory requirements through an innovative community streamside enhancement program called Tree for All (TFA). As the program grew, dozens of partners joined in to provide the resources needed to expand the scope and scale of the program. From the start the TFA program has helped catalyze and support a broad set of community values such as economic vitality, biodiversity, habitat connectivity, climate change resiliency, human health and recreation, and a one water philosophy.

NSES is able to leverage millions of dollars for streamside enhancement from voluntary incentive Farm Bill programs; conservation districts; local parks and open space providers; city, state and federal governments; and more than two dozen nonprofit partners. Together these collective resources produce landscape-scale results (140 river miles enhanced with more than 12 million native plants) while supporting rural and urban economies. By working at the landscape scale, NSES and TFA partners strive to create the watershed resilience needed to keep pace with rapid urban growth and mitigate stressors such as climate change.

Water Resource Recovery Operations & Services

About Water Resource Recovery Operations & Services

The Water Resource Recovery Operations & Services Department (WRRD) provides operation, maintenance and engineering for the District’s four water resource recovery facilities and 43 pump stations. Close to 66 million gallons of wastewater per day, on average, are pumped and treated to some of the highest standards in the nation. The water is then returned to the environment in the Tualatin River or reused for irrigation on golf courses, parks and sports fields. Solids removed from the wastewater are processed and used as soil amendments on farm land and nutrients are recovered and sold as a premium fertilizer. Digester gas produced in processing the solids is the fuel for cogeneration systems that offset approximately 45% of the electrical energy and 70% of the natural gas energy used by the facilities.

The department is organized in five operating programs that deliver on the core functions of conveying and treating wastewater: Durham; Rock Creek; Hillsboro/Forest Grove; Pump Stations; and Biosolids, Reuse and Fernhill. Three programs support the operating groups: Treatment Plant Services, Enterprise Asset and Technical Services, and Administration/Business Opportunities.


Durham is a tertiary wastewater treatment plant that treats an average annual flow of 21.4 mgd (million gallons per day). This program is responsible for day-to-day operation of the Durham Water Resource Recovery Facility, including process control; and mechanical, electrical and instrumentation maintenance.

Rock Creek

Rock Creek is a tertiary wastewater treatment plant that treats an average annual flow of 36.2 mgd. This program is responsible for day-to-day operation of the Rock Creek Water Resource Recovery Facility, including process control; and mechanical, electrical and instrumentation maintenance.

Hillsboro and Forest Grove

Hillsboro and Forest Grove are secondary treatment plants that treat an average of 4.4 mgd and 3.9 mgd, respectively. This program is responsible for day-to-day operation of the Hillsboro and Forest Grove water resource recovery facilities, including process control; and mechanical, electrical and instrumentation maintenance

Pump Stations

The majority of flow to the water resource recovery facilities is conveyed by gravity pipelines. However, due to topography or distance, pump stations are required to either lift the flow to gravity lines that can transport the flow to the water resource recovery facilities or to directly feed them via force mains. This program is responsible for the day-to-day operation of the pump stations, including process control; and mechanical, electrical and instrumentation maintenance.

Biosolids, Reuse and Fernhill

This program provides resource recovery of outputs from the treatment plants. Solids removed from the treatment plants are stabilized and converted to Class B biosolids, which are land applied as a beneficial agricultural soil amendment. During the summer, approximately 57 million gallons of effluent are utilized for urban irrigation. The Fernhill Natural Treatment System cools the effluent from the Forest Grove Water Resource Recovery Facility before discharge to the Tualatin River, while enhancing valuable wetland habitat in the process.

Enterprise Asset and Technical Services

This program provides technical services to the five operating programs to support their efficient and effective performance. The program has three groups: Technical Support (electrical, instrumentation and mechanical engineering), Control Systems and Asset Management. These groups have department-wide responsibilities for systems that benefit from standardized, central management.

Treatment Plant Services

This program provides engineering for project delivery and for technology development and research. Project delivery includes facility planning, project design and construction management. Technology development and research includes evaluating and
piloting new, innovative treatment processes, sensor technologies, and process control strategies to determine what should be
implemented full scale.
