The city says the red water is the result of a 16-inch water main break off FM 518 near City Hall, but the water is safe to drink.
The water main break happened around 9am after construction workers dug too deep and hit the main.
It took workers more than seven hours to flush out the line and complete the repairs.
The city says the majority of residents who were affected live in the Shady Crest neighborhood. However, Eyewitness News also received reports from residents in Oak Brook Estates off Dixie Farm Road.
