As DC Water prepares for a virtual town hall Wednesday night with residents affected by raw sewage flooding their homes last week, the water authority’s chief operating officer said ongoing construction projects should prevent similar events in the future.

Residents in the Riggs Park and Edgewood communities in Northeast D.C. are still dealing with the aftermath from the Sept. 10 downpour, in which more than 2.2 inches of rain fell in 75 minutes.

Although not unprecedented, the heavy flooding overwhelmed the District’s sewer system, causing water and sewage to back up into basements as the water filled the sewer lines in the street.
