(Washington, DC) – DC Water CEO and General Manager David L. Gadis today joined U.S. EPA Deputy Assistant Administrator Mae Wu, Congresswoman Eleanor Holmes Norton, and other District and Federal officials to celebrate the commissioning of the Northeast Boundary Tunnel (NEBT). The five-mile-long tunnel is the final component of the Anacostia River Tunnel System which will reduce combined sewer overflows to the Anacostia River by 98 percent in an average year, significantly improving water quality in the river. The NEBT will also mitigate flooding in many District neighborhoods where flooding has been a chronic issue during intense rainstorms.
