Have you seen our employees lately? We're busy working on a variety of projects including stream enhancement, treatment facility upgrades, system improvements, maintenance and more.

Below are a few highlights of our work around the Tualatin River Watershed. Have a question about one of our projects? Check out the information below to learn more.

Tualatin Basin Joint Project

The residents and businesses in the Tualatin Basin need dependable, safe and secure fresh water to ensure the long-term economic health and livability of our region. Water needs are expected to double in the next 45 years which means an additional 50,000 acre feet of water per year.


Fernhill is part of more than 700 acres in Forest Grove owned by Clean Water Services for water resources management. Fernhill utilizes natural treatment systems, or wetlands, to improve water quality by removing nutrients, cooling, and naturalizing the water after conventional treatment. Fernhill is designated an Important Bird Area and is also home to beavers, frogs, coyote and other wildlife.

Tree for All

Tree for All is a community partnership of cities, nonprofits, farmers, volunteers and others who have joined hands (and shovels) to plant native trees and shrubs along the Tualatin River and its tributaries. Streams lined with native vegetation provide cleaner, cooler water, better flood management, and fish and wildlife habitat. It’s good for Mother Nature and our community!

Butternut Creek Enhancement

Decades ago, Butternut Creek (in English and en Español, PDF, 2MB) meandered through forests and farms, swelling in the rainy season and dwindling in the heat. Now, it’s a single-thread, heavily incised creek that is disconnected from the floodplain and lined with invasive reed canary grass.

South Bull Mountain Regional Stormwater and Sanitary System Studies 

As the region develops, careful planning is needed to ensure appropriate infrastructure is in place in each community to protect the environment and serve our growing population. To support this effort, Clean Water Services is performing regional stormwater and sanitary system studies.

Brookman Sewer & Cedar/Goose Creeks Assessment

Clean Water Services and the City of Sherwood are working together to support Sherwood's future. This project (PDF, 285KB) will bring necessary sewer services to Sherwood’s expanding community and natural resource enhancements.

A study has identified a sewer alignment that will provide service to the new Sherwood High School and upcoming development in the Brookman area. The alignment will place a new line in, or near, Goose Creek and Cedar Creek, as well as along sections of roadways and surrounding areas.

Some property owners will be directly impacted by the placement of the sewer pipe and subject to a temporary or permanent easement. This Easement Timeline (PDF, 240KB) provides impacted property owners with an idea of what to expect as Clean Water Services moves forward on this project. Property owners will also have opportunities for natural resource enhancements as part of this project.

Cedar Mill Creek

Infrastructure projects can present the opportunity to work in partnership and include additional improvements at an overall reduced cost. The need to replace an aging pipe in the Cedar Mill Creek watershed provided Clean Water Services with an opportunity to also richly invest in local environmental and wildlife habitat improvements.

Derry Dell Creek Enhancement

Good things happen when partners work together. By collaborating in 2014 on this $1.8 million project, the City of Tigard and Clean Water Services restored Derry Dell Creek to the vibrant ecosystem that is beginning to thrive.

North Bethany Enhancement

This collaboration began as an opportunity to maximize efficiency, coordinate infrastructure, and minimize potential conflicts between two distinct projects that overlap geographically. One project involves an extension of the North Bethany Trunk sewer and the other involves exploring and implementing stream restoration and natural treatment along the West Tributary to Abbey Creek to slow and filter stormwater runoff.

Routine Project Work


Clean Water Services and city crews maintain the storm and sewer system by cleaning catch basins, sweeping streets, keeping up water quality facilities and more. Have a question about these activities in your neighborhood? Contact the City or call our Field Operations team at 503.547.8100. 

Water Quality Facilities

If you have questions about a neighborhood swale, or other vegetated area, first check to see if there's a sign listing contact information. If no sign or contact information is available, please contact the City or call our Field Operations team at 503.547.8100.


For questions about a project in your neighborhood where you've seen Clean Water Services' signs, trucks or staff call 503.681.3600.
