About 150 Caldwell County water customers are under a boil water advisory after a water line break near the town of Granite Falls. County water line customers that are affected live on Dudley Road at Moorelane Park Drive up to Grace Chapel Road and all on Wike Road. These customers are advised to boil water for consumption or use bottled water until testing can be done to determine if the water is clear. Updates will be sent as they occur, according to Caldwell County Public information.
