Crews were out in force Sunday to repair the breaks. City officials say the water is safe to drink, although some blocks might be without water until repairs are complete.
The problem began Saturday morning. That's when an 84-inch water main began leaking, sending water into the pumping station. Officials shut down that water-treatment plant and relied on another plant to pick up the slack.
But that led to an increase of water pressure throughout the system, which caused at least 21 other water-main breaks.
The cause of the original leak hasn't been determined.
