Temperatures are recovering from this week’s severe cold snap, but the Maryland suburbs’ water pipes are still suffering.

Water mains in Montgomery and Prince George’s counties are continuing to burst even as air temperatures rise because unusually cold water from the Potomac and Patuxent rivers, which supply the area’s drinking water, is just now making its way through the water distribution system, said a spokeswoman for the Washington Suburban Sanitary Commission (WSSC).

Since Tuesday morning, 88 pipes have broken in the two counties, said WSSC spokeswoman Lyn Riggins. Of those, 43 have been fixed and an additional 45 are undergoing repairs or are on the list to be repaired, she said. The number of breaks is expected to continue to grow, she said.

Residents with broken water pipes inside their homes should call a plumber, Riggins said. WSSC is responsible only for water mains in the street and the connections to homes and businesses, she said.
