Nearly two floors of a state office building have become uninhabitable because of serious flooding.
The flooding started Sunday morning on the ninth floor of the Andrew Jackson Building.
The floor is a secure area and is supposed to be patrolled on a regular basis by a security guard, but state officials said no one noticed the flooding until around midnight Sunday.
By that time, there was an inch of water on the ninth floor, and water had severely damaged parts of the eighth floor and flowed to sections of the seventh floor.
The work space of nearly 100 state employees was impacted. Some have been put on administrative leave until the clean up is finished.
Four state agencies had offices affected including the Department of Revenue, Tennessee Health Services and Development Agency, the Tennessee Commission on Children and Youth and the Tennessee Commission on Aging and Disability.
State officials with Department of General Services do not know how much the damage will cost the state.
Samples of the water have been sent off to a lab for testing.
The leak happened during a planned power outage on Sunday.
A flush valve in a toilet on the ninth floor failed to close and water continued to run.
State officials estimate clean-up will take until March 7.
The Walden Security guard who was on duty Sunday night is no longer assigned to the state.
