City officials said repairs and testing will continue through Monday.
FLINT, Mich. --Flint announced a citywide boil water advisory after a water main broke Friday morning, causing the pressure of the entire city's system to drop below safe levels.
Flint officials have not identified the cause of Friday's main break. The notice mentioned that the reservoir and pump station at fault was scheduled for renovation later this year. The federal Safe Water Drinking Act's public notification rule includes requirements to notify the public about the loss of water pressure in drinking water systems. Michigan's Drinking Water and Environmental Health Division notes that a low-pressure event can allow contaminants to enter a water supply; however, the declaration of a boil water advisory during a low-pressure event can be made on a case-by-case basis.
Meanwhile, city officials recommend that residents use bottled water or filtered and boiled water for consumption and cleaning purposes. State guidance recommends that residents boil cold filtered water for one minute to kill bacteria and microorganisms.
