D.C. Breaks Ground on Largest Construction Project Since Metro

On Oct. 12, the District of Columbia Water and Sewer Authority broke ground on its $2.6 billion — the largest construction project since the building of the city’s Metrorail. The first phase of the project, a 594,000-m (157-million-gal) storage/conveyance tunnel, is designed to eliminate 90% of combined sewer overflows to the Anacostia River. Future projects will focus on reducing overflows reaching the Potomac River and Rock Creek.
