Houston Airport Systems spokesperson Bill Begley said construction workers were working on the airfields when a waterline was hit.
The damage to the waterline caused low water pressure on terminals four and five.
Airport officials had to shut down several restrooms while workers manually flushed the toilets.
A few of the restaurants inside of the airport had to close during the incident as well.
Begley said they turned off the valves to stop the break and the water pressure slowly returned.
