Aerial image of the Salmon Creek Treatment Plant
The Salmon Creek Treatment Plant is the last part of the wastewater conveyance system. All sewer pipes and pump stations are designed with one purpose: to reliably carry wastewater from homes and businesses to the treatment plant. Wastewater is then treated to regulatory standards and released back into the environment.
The plant is an essential part of our public infrastructure. It serves over 50,000 homes and businesses in our service area. Our highest priority is keeping the plant operating to industry standards, while meeting all environmental regulations. The plant has 19 full-time staff, including managers, maintenance technicians, certified operators, and a laboratory coordinator.
To ensure the plant operates in a safe, reliable and cost-effective way, all plant operations are monitored 24 hours a day, 7 days a week through a modern, automated computerized control system. Backup generators ensure operations run consistently at all times, even in the event of a power outage. The entire perimeter of the site is fenced for safety.
In 2022, Clark Regional Wastewater District took over operations of the plant. Responsibilities include:
Construction timeline
Construction relating to the Columbia River Outfall and Effluent Pipeline project and the Secondary Treatment Process Improvements projects will require increased truck traffic carrying materials, equipment and workers to the construction sites. This increased traffic will impact area neighborhoods. Expect increased truck traffic on the roads highlighted during the periods of construction. Any landscape disturbances made during construction will be fully restored and we will work to minimize disruptions to commercial and recreational interests.
Construction will occur (for the most part) between 7 am – 7 pm, Monday – Friday.

Odor Control Facilities Map
New equipment was installed in 2021 and now captures and treats odor that is generated as a result of regular treatment operations. However, some odor generating events may still occur from time to time, such as when treatment processes are taken off-line for cleaning and repair.
Construction on the new outfall and shoreline work began in 2021 and is nearing completion. Construction on the new pipeline is scheduled to begin later this year and continue through 2025. Use the interactive map in the “Construction Schedule and Impacts” tab above to learn more about the potential impacts related to construction and truck traffic.
Kayak trail impacts: Trucks carrying construction equipment and materials will use the kayak trail through 2023. During this time, trail access will be restricted. Any impact to the trail will be restored.

Construction is slated to begin later this year and be completed by the end of 2025. Project design and permitting are complete and the competitive bid process is underway to select a construction contractor.
Materials may be stored at a nearby property owned by the school district on NW McCann Road between NW 47th Ave and NW 44th Ave. Use the interactive map in the “Construction Schedule and Impacts” tab above to learn more about the potential impacts related to construction and truck traffic.
A new perimeter fence will be installed around the treatment plant when construction occurs. The new fence is intended to create a safer, more secure environment for the treatment plant and will be constructed of black vinyl coated fence material with three strand barbed wire across the top. The fence will be 8 feet high, including the barbed wire.
