Chambers Creek Regional WWTP

Harbor Pacific built the new Solids Thickening Building, Utilidors, Digester Control Building, and Digesters 4 and 5 as part of a major expansion at the Chambers Creek Wastewater Treatment Plant for Pierce County, WA that will double the treatment capacity of the plant. The project required the placement of over 14,000 cubic yards of cast-in-place concrete, including two 1,100 cubic yard monolithic pours for the digester lids.
