LARGO, Md. (CBSDC) — A water main break is putting a damper on Thanksgiving plans for nearly 600 homes in Prince George’s County.

The Washington Suburban Sanitary Commission says a 16-inch water main broke in the 10300 block of New Orchard Drive in Largo.

The break, which occurred in a pipe installed in 1974, was first reported around 4:30 a.m. Thursday

WSSC has set up a water station at the corner of New Orchard Drive and Butterworth Lane where affected customers can receive six-gallon cases of water.

Officials say it is unclear when the break will be repaired.
