Midwestern Placer Sewer Regionalization Project

City of Lincoln

Construction Cost: $42 million

This $42 million project that involved three separate construction contracts that converted the Placer County wastewater treatment plant north of Auburn, CA to a pump station, constructed a 22-mile long, 24-inch diameter HDPE pipeline from the wastewater plant in Auburn to a connection point in Lincoln, CA., and expanded the City of Lincoln’s wastewater treatment plant to process the additional flows into the plant.  The services included managing three separate contracts managed by three CM teams and coordinating work between the City of Lincoln and Placer County to minimize disruptions to their respective operations. 

The construction work at the Placer County facility involved a new deep concrete pump station excavated in bedrock using drilling and hammering methods, construction of a new electrical power and controls facility, and complete demolition of the existing wastewater treatment plant followed by the construction of two earthen embankment detention basins to use in the event of a power loss to the pump station.  The pipeline work involved construction of the pipeline below existing roadways which often involved rock excavations that used hammering, drilling, and blasting.   The work crossed through environmentally sensitive areas and private property.  The work at the City of Lincoln’s WTRF included construction of a new oxidation ditch, secondary clarifier and expansion to the tertiary filtration system.
