Warren County High School students got an unexpected surprise Friday when school was canceled due to sewer problems outside the school.Director of Schools Bobby Cox said a problem was found Thursday afternoon with the sewer outside the cafeteria. “The sewer right by the cafeteria outside the building was found to be broken and over time rock had filled in the pipe causing it to clog up. It was found Thursday and was being monitored but it was decided to close the school to students today because they couldn’t cook in the cafeteria and the bathrooms located near the cafeteria drain into that line.”Warren County Schools maintenance workers Paul Young and David Bates worked most of the night Thursday night along with Fred Hall and crew from Hall’s Backhoe and Dozer service to remedy the problem.
