Repairs on a pipe rupture that has sent sewage flowing into the Potomac River northwest of Washington, D.C., will take weeks more to repair because of an unexpected blockage, according to the local water authority.
In a release posted on its website Thursday, DC Water, which operates the sewer system, said a video inspection of the pipeline revealed the blockage inside the collapsed sewer line “is far more significant” than originally thought. It said it discovered a large rock dam about 30 feet (9 meters) from the breach in the sewage line, which requires treatment before the current spill can be addressed.
