Description
The Centralia Wastewater Treatment Plant project is designed for an average annual flow of 2.7 million gallons per day, but is capable of processing a peak flow of 10 million gallons per day. The service population for the new plant is 17,158.
The new plant will replace an existing plant at another site. The project requires transferring equipment from the existing plant to the new location.
Work on the new plant includes construction of headworks, two aeration basins, a blower building, two secondary clarifiers, an ultraviolet disinfection system, electrical building, and both effluent and plant drain pump stations.
Additional components include a facility for handling solids, with a belt filter press, dewatering and lime stabilization of biosolids, a storage facility for biosolids, and a maintenance facility.
