Sprinkler leak at the North Middle School Saturday caused minor damage.

Sprinkler leak at the North Middle School Saturday caused minor damage.

Sub-zero temperatures Friday and Saturday froze, then burst, a fire suppression sprinkler supply line at the North Middle School Saturday afternoon, soaking one second floor classroom and damaging the first floor classroom below it.

The Groton Fire Department responded to an alarm triggered by the sprinkler system activation around 2 p.m. Deputy Chief Clarence Jefferson said later, “Basically, they had a sprinkler line freeze up on the second floor of the Middle School and when it thawed out, it let loose. We just shut it off, put some salvage covers down, and recharged the parts of the system that we could recharge, leaving out that zone. They had some people coming in to help them, and we just assisted where we could.”

On Sunday, Groton-Dunstable Regional School Committee chairman John Giger said administrators told him that two science rooms had been damaged and would require new ceilings that would probably be installed during February vacation.

The school will be open for classes on Monday.
