A water main break on Georgia Tech’s campus on June 27 left large sections of Atlanta without service. A boil-water advisory was in effect for some customers with service while repairs continued, according to Mayor Keisha Lance Bottoms.

As of 9 p.m., the boil-water advisory no longer included Buckhead or Sandy Springs.

Under a boil-water advisory, anyone with water service is advised to boil tap water for 1 minute before using it for any drinking, cooking and tooth-brushing. Using bottled water is another option.

The break occurred at Hemphill Avenue and Ferst Drive, according to the Atlanta Department of Watershed Management. Bottoms declared the boil-water advisory around 1:30 p.m.

Initial communications about the break were chaotic, with the Watershed Management website crashing and many residents on social media saying the department’s phone number disconnected when called. Bottoms said on Twitter that a boil-water advisory was in effect, while the city and Watershed Management accounts only said that an advisory was forthcoming.

The exact areas of the boil-water advisory were the subject of limited and contradictory information, including two different boil-water advisory maps circulating.
