A water main broke Tuesday morning between Buildings 260 and 300, causing some classroom damage and prompting several classes to relocate.

After the main broke between 10 and 11 a.m., water flooded the basement of Building 260, known as the language corner. About an inch and a half of standing water covered classroom floors in the basement, causing extensive damage to the carpet, said Julie Hardin-Stauter, associate director of zone management. All basement classrooms in the building are closed, and classes normally held in those rooms will be relocated for two to three weeks while damages are repaired.

Meanwhile, technicians worked Tuesday afternoon to repair the main between the buildings. The six-inch plastic line is about 10 years old and surrounds Building 300, according to Bob Park, the University water shop’s lead technician. He expected repairs would be finished by the end of the day, restoring water to Buildings 40, 50, 260 and 300, Memorial Church and a nearby men’s restroom.
