More than 150 tenants were displaced after a small fire led to water damage at The Manor at Northgate Terrace, a senior living apartment building, Saturday night.

The Knoxville Fire Department responded to 4301 Whittle Springs Road at approximately 7:40 p.m. to the report of a fire in apartment 802 in the building. Officials said a sprinkler head activated before their arrival and extinguished the fire but continued to discharge water.

Water filtered through the ceilings to the apartments below and eventually made its way to the lobby and ground floor. KFD said firefighters tried to stop the water flow before the ultimate decision was made to disengage the sprinkler system.

Due to the condition of the electrical corridors of the building, the tenants were evacuated for their safety, officials said.
