Mortenson was recently selected by the City of Coos Bay, Oregon to provide CM/GC services to build the City’s new wastewater treatment plant, continuing our leadership in the State of Oregon's water/wastewater industry. The new WWTP will tie into the City's existing treatment plant across the street.

The new plant includes an influent pump station, headworks, sequence batch reactor system, equalization basin, UV disinfection system, an office/lab building and a shop/garage building.
