About Us

Established in 1866, the Philadelphia District manages water resources of the Delaware River basin; builds facilities for the Army and Air Force; and provides engineering and environmental services for other agencies. We serve more than nine million people across portions of Delaware, Maryland, New Jersey, New York and Pennsylvania. But our reach extends around the world with our support to Overseas Contingency Operations.

Most of our approximately 500 employees work out of the home office in Philadelphia, with the rest at field locations throughout the District’s 15,000-square-mile geographic area.
