Project Spotlights

Portland, OR  |  Completed Winter 2024

The Columbia Boulevard Wastewater Treatment Plant treats an average of 450 million gallons per day during peak wet weather flows. The Secondary Treatment Expansion Program (STEP) — a City of Portland and Bureau of Environmental Services project — required replacement of existing facilities, a complete upgrade of the solids handling facility, and the relocation of critical medium-voltage switchgear, transformers, and motor control centers.

In partnership with Kiewit Infrastructure West, our team took on the fabrication and installation of all HVAC duct and foul-air, coated stainless exhaust in the reconstructed Blower Building, Effluent Pump House, RAS Pump House, and Solids Processing Building.
