****UPDATE: The advisory was lifted on Friday afternoon.****

A portion of Chatham County is under a boil-water advisory after a contractor struck a water main on Wednesday evening.

County officials say the ruptured water main is affecting a portion of the county’s North Water System in northeast Chatham County.

“We are issuing the boil water notice as a precaution due to the pressure drop in the system,” assistant county manager Dan LaMontagne said in a release. “We do not expect this to last more than one day.”

Officials said in a release that the leak had been isolated and was being repaired as of Wednesday night, but the advisory was still in effect on Thursday morning.

The areas impacted by the advisory are Manns Chapel Road east of Great Ridge Parkway, businesses within Cole Park Plaza and all customers north of the Manns Chapel Road intersection along Highway 15-501 – including Old Lystra Road and the Wal-Mart shopping center.

County officials will notify residents once the advisory has been lifted.
