DC Water's newest tunnel boring machine (TBM) is here to carve out the final and longest tunnel segment for the Anacostia River. When this behemoth is lowered 100 feet into the ground and assembled fully, it will mine the Northeast Boundary Tunnel, joining the First Street Tunnel in Bloomingdale to the lower segment already conveying combined sewage to Blue Plains. 

In keeping with tradition, DC Water will name the TBM before it starts digging. Please join us as we take another step towards a cleaner Anacostia River.
