Washington, DC's Biosolids Management Program

The District of Columbia Water and Sewer Authority has embarked on a $460 million biosolids management program (BMP) at its Blue Plains Advanced Wastewater Treatment Plant. The program will transform DC Water’s current Class B lime-stabilization processing system into the largest Class A system in the world.

The Main Process Train (MPT), which had a cost estimate of about $225 million and included large-scale sludge screening, pre-dewatering centrifuges, thermal hydrolysis process (THP), and digestion processes, was delivered using the design-build model.
