The century-old combined sewer system in the District of Columbia is not equipped to handle the population growth experienced during the last 100 years. The sewer system is undersized and has caused chronic flooding in the Bloomingdale and LeDroit Park neighborhoods, at the Rhode Island Metro Station area, and on Mount Olivet Road NE for decades.
To address the problem, DC Water has designed the Northeast Boundary Tunnel (NEBT) to connect with the existing sewer system, significantly mitigating sewer flooding while improving the water quality of the Anacostia River. The NEBT is the largest component of the Clean Rivers Project and will start just south of RFK Stadium and extend north to Rhode Island Avenue and west to R Street NW.
