A member of the D.C. fire department donned water rescue gear Wednesday to search a basement in Southeast inundated after a water main break, officials said.

No one was found in the basement, and no one was injured, although fire personnel saw water “cascading” into the basement of a rowhouse that “almost completely filled” it, according to Vito Maggiolo, spokesman for the D.C. fire department.

Fire personnel responded to the 600 block of East Capitol Street SE about 1 p.m. after neighbors reported people might be trapped inside the flooded basement, Maggiolo said, and searched the basement after the D.C. Water and Sewer Authority cut off service.

The water main break was not on the street, but on the property of the home most affected, according to Maggiolo. A small sinkhole developed on the front walk where the water came up.
