The affected areas include, but are not limited to: Cabbagetown, Edgewood, Old Fourth Ward, West End, Peoplestown, Reynoldstown, Mechanicsville, Summerhill, Avon Avenue and South Fulton County.
Areas east to Moreland Avenue and west of downtown may also experience a loss of water pressure.
Atlanta Watershed Management said residents in these areas should boil water before using it to cook, drink, or brush teeth. Water should be brought to a rolling boil for at least one minute.
Infants, the elderly and those with immune deficiencies especially heed this warning.
