Water boil advisory issued by Great Lakes Water Authority for 935,000 people after water main break - CBS News

About 935,000 people in southeastern Michigan were advised to boil their drinking water Saturday after a break was reported in a critical pipe.

GLWA is working to isolate a break on a 120-inch water transmission main that distributes finished drinking water from our Lake Huron Water Treatment Facility to communities in the northern part of GLWA’s drinking water service area.

Crews identified the location of the leak, which is approximately one mile west of the authority's Lake Huron Water Treatment Facility.

Clair County, called a water main, carries treated water from Lake Huron and is the largest in the system, the agency said.

Boiling water before using it will kill bacteria and other organisms that may be in the water," the GLWA said.

"Boiled, bottled or disinfected water should be used for drinking, making ice, washing dishes, brushing teeth, and preparing food until further notice," the agency said.
