About the Project
Blue Plains, in Southwest Washington, is DC Water's wastewater treatment plant, which DC Water calls the largest treatment plant of its kind in the world. The upgrades replace the filters' block-type underdrains and dual media with nozzle-type underdrains and mono-media, and repair concrete in the filter walls, floors and channels. DC Water is delivering the work through a construction-manager-at-risk (CMAR) portfolio for the plant's filtration and disinfection facilities.
