Just a few weeks past the one-year anniversary of a major flood at the C.H. Booth Library, a frozen pipe burst above the Children's Department cascading water and debris down into the Children's Department late Tuesday morning.

No one was injured, but the burst pipe tied to the library's fire suppression sprinkler system pooled inch-deep water across the floor, greeting staffers who sloshed around the area beginning to assess the damage when The Bee arrived on scene.

Fire Marshal William Halstead visited the scene and said a pipe connection to the sprinkler system split, causing the indoor deluge.

Hook & Ladder, along with Sandy Hook, volunteers initially responded to the call, with Hook & Ladder crews remaining on scene to assist with preliminary cleanup work.

The library is now closed and will remain closed until building officials complete their investigation, and clear the building for occupancy. Library Board President Robert Geckle arrived on scene shortly after firefighters.

Town Building Inpector John Poeltl said as long as he and the fire marshal determine the sprinkler system is operable, they will be allowed to open the rest of the facility while clean-up and restoration in the children's area continues.

Mr Poeltl said the latest damage was not as severe as what resulted from a 2014 leak, which also affected upper floors in the historic building.

The leak and ceiling collapse occurred about one year and six weeks after another major leak and flood when sprinkler pipes above the second floor froze and burst on Saturday, January 4. That incident causing the ceiling to collapse in the director’s office and tech services area of the second floor, as well as in the first floor Children’s Department.

The dedication of library staff, the Board of Trustees, and remediation specialists led to reconstruction, improved technology, a new traffic flow pattern, and the implementation of previously planned updates, all within two months.

The library reopened to the public as of March 8, and welcomed the public at a special Reopening Celebration, March 22. The local building official was optomistic that this incident would not affect library operations for very long.

"As long as they get the pipe repaired and restore fire protection, they could be reopened in a week or two," Mr Poeltl said. "The damage was mostly to rugs and the ceiling tiles."
