A precautionary boil water notice was issued for 13 communities after a water main break caused a loss of pressure Saturday morning.

The advisory was lifted for the following communities: Clinton Township, Flint, Flint Township, Rochester Hills, Pontiac, Auburn Hills, Orion Township, Utica, Troy, Sterling Heights and Lapeer.

Officials say that crews have identified the location of a leak on a 120-inch water transmission main that distributes finished drinking water from a Lake Huron water treatment facility. According to Great Lakes Water Authority, an estimated 935,000 people were impacted as of Saturday morning. Officials are investigating the cause of the water main break.

Residents are urged not to drink the water without boiling it first. GLWA states that crews will open emergency connections to other mains once the leak is isolated to restore flow to those impacted.
