Newberg Wastewater Treatment Plant Expansion

Mortenson completed the Newberg Wastewater Treatment Plant Expansion as part of a $35 million, five-phased heavy civil GC/CM program delivered over several years. The project included construction of a new wet well structure, emergency backup generator, sanitary sewer piping, secondary clarifier, administration building, and a new headworks facility. Delivered through a collaborative CM/GC approach, the improvements enhanced system capacity, reliability, and long-term operational performance for the City of Newberg’s wastewater infrastructure.
