Several rooms in Cabot House's D entryway were evacuated around midnight tonight after a sprinkler flooded room D-41.

According to messages sent to email lists, the water headed downward to rooms D-31, D-21, and D-11, causing more than 10 students to evacuate to friends' rooms for the night. It is unclear what caused the sprinkler to burst.

A resident of D-41 reported that "gallons upon gallons of brown water flooded over the top of the pipes closet" in an email to the Cabot open list.

House personnel responded to the incident immediately by placing fans to dry out the affected rooms.
