L. S. Caldwell & Associates, Inc. (LSC) was responsible for the development, implementation, and monitoring of the Fair Share Objective initiatives for the District of Columbia Water and Sewer Authority’s (DC Water) Clean Rivers Project. This $2.6 billion program was the result of a Consent Decree signed by the District of Columbia, the Environmental Protection Agency, and the Department of Justice. DC Water was required to clean up the Anacostia and Potomac Rivers by 2025. Five discrete portions of the work, called Divisions, totaling approximately $404,000,000. Twelve Divisions were anticipated.
Division A
The Blue Plains Tunnel (BPT) consisted of two aligned shafts that drop down 140 feet to a 23-foot inside diameter tunnel located at the northwest corner of the Blue Plains Advanced Wastewater Treatment Plant. It resulted in the construction of 24,000 linear feet of tunnel and 5 new shafts. The tunnel extended from the Blue Plains site, northwest into the Potomac River, running parallel to the Naval Research Laboratory complex, before turning back to the shoreline near Joint Base Anacostia Bolling (JBAB), formerly known as Bolling Air Force Base and the Anacostia Naval Annex. The tunnel continued along the shoreline past JBAB, and bore east to the Poplar Point Junction Shaft, located south of the existing DC Water Poplar Point Pumping Station. Turning north, the tunnel went beneath Poplar Point and the Anacostia River to terminate at the Main Pumping Station Drop Shaft on the north side of DC Water’s Main Pumping Station.
