GREENBACK, Tenn (WVLT) -- A sewage problem will close Greenback School in Loudon County for the rest of the week.

School administrators at Greenback School say the school experienced a sewage backup problem today.

They tried to fix the problem, but were unable to do so.

Workers will need Thursday and Friday to accomplish that task.

Students stayed in school during the attempted repairs today, but school leaders say they were sent to another part of the school to use the bathroom.

Greenback School has students in K-12th grade.
