Columbia Boulevard Project

The Columbia Boulevard Wastewater Treatment Plant – Secondary Treatment Expansion Program (CBWTP STEP) is a City of Portland – Bureau of Environmental Services Project. The CBWTP treats a daily average of 450 million gallons per day during peak wet weather flows. The project includes the addition of two (2) new 150-foot diameter clarifiers which requires demolishing and replacing existing facilities, a complete upgrade of the solids handling facility and the relocation of critical medium voltage switchgear, transformers, and motor control centers.
