The Detroit Water and Sewerage Department said plans to fix a 30-inch water main today will impact service within an eight-block area.
The initial break happened on Farmer Street near Bates Street.
DWSD will be making the fix beginning around 12 p.m. It should be fixed by Tuesday morning.
The outage affects buildings near Woodward Avenue and East Congress.
The sewerage department said that some businesses could have low water pressure or no water service at all as a result.
