Water Environment Services
Funding for RiverHealth Stewardship Grants comes from surface water revenue.
Clackamas Water Environment Services (WES) is awarding $330,000 in grants through its RiverHealth Stewardship Program to 13 organizations dedicated to the protection of local watersheds.
Clackamas Water Environment Services (WES) will hold three public hearings before the Clackamas County Board of Commissioners (acting as the governing body of WES) on Wednesday, June 18, 2025 at 10 a.m., to consider the following matters. Hearings will be held in person and via Zoom.
Opened in 1974, the Kellogg Creek Water Resource Recovery Facility (WRRF) plays an important role in serving the Clackamas Water Environment Services (WES) community. It treats wastewater from Happy Valley, Johnson City, Milwaukie, and unincorporated areas of Clackamas County. Each day, the facility cleans nearly 7 million gallons of wastewater before releasing it into the Willamette River.
After 50 years of service, it's time for much-needed updates to the facility's administration building to better serve current and future needs. The project will also move some staff facilities into the administration building, which will create space inside the main plant for future improvements to wastewater treatment.
Construction is scheduled to begin in the summer of 2026, with work expected to last about 12 months.
Planned upgrades include:
In recognition of its excellence in plant operations and permit compliance, the Kellogg Creek WRRF received the Peak Performance Awards from the National Association of Clean Water Agencies (NACWA) in 2021, 2022, and 2023.
Clackamas Water Environment Services (WES) owns and operates the sewer system that carries wastewater from homes and businesses in Happy Valley and nearby areas to our treatment facilities. To ensure we can continue providing safe and reliable sewer service in the future, we need to make improvements and upgrades to the Intertie 2 Pump Station.
The Intertie 2 Pump Station diverts wastewater from one treatment plant, the Kellogg Creek Water Resource Recovery Facility, to another, the Tri-City Water Resource Recovery Facility. The pump station was built to be expanded as the area grows. It is now almost at full capacity. This project will add a new pump and new pipes to connect to a new 30-inch force main.
Currently, the pump station moves wastewater using a 20-inch-diameter pipe. Building the new 30-inch force main will help pump more wastewater and increase the station’s capacity. Parts of the 30-inch pipe were built in 2012, and this project will finish the construction of the remaining sections.
From Nov. 17 through January 2026, Johnson Road will be closed to thru traffic between SE Lake Rd and SE Thiessen Rd to install a new sewer line. Homes and businesses will remain accessible during construction, however detours around the construction may be necessary.
Your patience and cooperation are greatly appreciated as we work to complete this important sewer improvement.
Dates: Monday, Nov. 17, 2025 to through January 2026
Work Hours: Monday – Friday, 7:00 a.m. to 5:00 p.m.
Local Access: Homes and businesses located inside the closure area will still be accessible. Please expect short delays and follow directions from construction crews.
Detour: All thru traffic must follow the marked detour using SE Lake Rd, SE Webster Rd, and SE Thiessen Rd.
Evenings & Weekends: The road will be OPEN to all traffic outside of work hours (after 5 PM on weekdays and all day Saturday and Sunday).
Pump stations are used to help transport fluids from one point to another. They play an integral role in sanitary sewer collection systems. Our sewer system relies on pump stations, or lift stations, to push wastewater from point A to point B, especially in cases where gravity can’t move flow from a low-lying area to higher ground.
How pump stations work
A force main is a pressurized sanitary sewer pipe. Force mains are used where gravity is insufficient to move wastewater through a sewer line.

The total cost of the project is estimated at $23,650,000.
The IT2 Pump Station Expansion and 30-inch Force Main project is part of WES’ Capital Improvement Plan. As such, it is a planned expense that has been included in budget discussions and rate studies. We are committed to keeping rates affordable while meeting the needs of growing communities and replacing old infrastructure.
There will be traffic impacts along SE Johnson Rd and SE McKinley Ave in Clackamas, SE Cason Rd and SE 82nd Drive in Gladstone, and Washington St. in Oregon City. We will share additional details of the construction impacts as more information becomes available.
