Classes to resume at Bonsall High, Sullivan Middle after closure due to 'water issue.'

Classes are set to resume at Bonsall High School and Sullivan Middle School on Thursday after they were closed Wednesday due to an issue with plumbing on campus, the Bonsall Unified School District confirmed.

Officials became aware of the problem at the two schools — which share a campus — after middle school students had arrived for class at 7:45 a.m. but before the high school’s start time at 8:45 a.m., the district said.

High school students were turned away before classes began, and middle school students were sent home for the day.

The district could not confirm what the plumbing issue was, saying only that the Rainbow Municipal Water District was evaluating the problem. The issue was resolved by Wednesday afternoon, the district said.

3:30 p.m. Wednesday
