Previously: A water transmission line break Monday evening prompted officials to issue a boil water advisory for eight communities in Oakland County.

The Great Lakes Water Authority issued the mandatory advisory for Commerce Township, Farmington Hills, Novi (the area bounded by 14 Mile on the north, Eight Mile on the south, Napier on the west and Haggerty on the east), Oakland Township (specifically the subdivisions The Hills of Oakland and Kings Pointe), Rochester Hills (north of Hamlin and west of Livernois), Walled Lake, West Bloomfield Township and Wixom.

Residents should not consume any water without boiling it first for at least one minute and then letting it cool before using.

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

The transmission main break occurred at about 5:45 p.m. Monday on 14 Mile Road between Farmington and Drake, causing a loss of water pressure in the water distribution system, officials said.

A loss of pressure can lead to bacterial contamination in the water system. Boiling water before using it will kill bacteria and other organisms that may be in it.

The Great Lakes Water Authority is investigating what caused the line to break.

General guidelines on ways to lessen the risk of infection by microbes are available by calling the Environmental Protection Agency Safe Drinking Water Hotline at (800) 426-4791.
