The number of water mains bursting in Montgomery and Prince George’s counties due to plunging temperatures continued to grow Wednesday, as utility crews worked to repair 48 broken mains, a jump from the 38 pipes that required repairs Tuesday.

Crews for the Washington Suburban Sanitary Commission (WSSC) are working 16-hour shifts around the clock to keep up with the spike, officials said. However, repairs that usually take four to six hours are taking longer because workers must rotate into and out of their vehicles to get relief from the bitter cold, WSSC officials said.

Crews have repaired 16 broken mains since Tuesday morning, officials said.

On a typical January day, the WSSC has about eight broken mains, officials said.
