Boil water advisory lifted for all of Farmington Hills

A week after a 47-inch water main break in Farmington Hills, officials on Monday morning cleared the city’s last neighborhoods from a boil water advisory.

The restriction was gradually lifted from a dozen affected communities starting late last week; however, a failed pressure regulating valve led to additional water testing for a portion of northwest Farmington Hills.

The Great Lakes Water Authority (GLWA) issued the boil water advisory on October 23 after a break in the main along 14 Mile Road, between Farmington and Drake Roads. Described by one official as “unprecedented,” the incident affected more than 300,000 metro Detroit residents and business owners.

GLWA expected to have everyone back online by Friday evening, but a leak discovered during tests on the new pipe pushed the target date into the weekend.

The advisory and related water pressure issue resulted in Farmington Hills school and business closures. The Farmington Community Library Main Library also shut down until water pressure was restored.

City of Farmington Hills engineers started evaluating 14 Mile Road damage on Wednesday. The road will remain closed; the city hasn’t yet determined when it will reopen.
