DC Water Biosolids Management Project

DC Water's 370 mgd Blue Plains wastewater treatment plant is one of the largest in the United States. The agency undertook a major project for the replacement of the plant's lime stabilization treatment system with new biosolids management facilities designed to produce a class A sludge product and reduce sludge volumes by 50%.  Hawkins represented DC Water as owner's lead counsel in the review of possible alternative project delivery methods and served as special counsel in the procurement and negotiation of the new $200 million main process train on a design-build basis.   The project, which uses the Cambi THP process and was implemented in conjunction with a digester gas combined heat and power project, is in successful operation, with annual residuals disposal cost savings to DC Water exceeding $15 Million.
