DC Water's $2.6 billion program will reduce combined sewer overflows (CSOs) to the Potomac and Anacostia River. Facilities that control CSOs are typically much deeper than conventional infrastructure, requiring specialized structures and construction. This presentation describes the evaluation, design and construction coordination efforts to accommodate the new internal structures, mechanical equipment and piping, including 3000 HP pumps and a 13-foot diameter steel manifold, within the existing 135' diameter x 165' deep tunnel launching shaft.
