MAGNA, Utah - Officials with the Granite School District have closed Matheson Junior High after a pipe burst and flooded the school overnight.
Benjamin Horsley with the Granite School Distirct said the worst damage is in the school’s computer lab.
The first call came in right around 5 a.m. when Unified Fire crews responded to an alarm at the Magna school. 
When they arrived, firefighters realized it was a flood and not a fire that triggered the alarm and called school officials.
Authorities determined a sprinkler pipe was exposed to the elements overnight thanks to an open damper on the roof right above the computer lab.
At some point early Tuesday morning, that pipe froze and burst.
Water flowed for nearly half an hour, spilling thousands of gallons onto the second floor which then flowed down onto the main floor of the school.
At about 7:30 a.m. Granite District officials made the call to cancel classes for the day.
Despite all of this damage and the extensive cleanup, district officials say the school should be ready for classes again Wednesday.
The school said it will make up this day Tuesday, March 29.
