A leaky water pipe flooded eight classrooms on the campus of Fallbrook High School, according to a school district official.
The flooding came after another water pipe problem, forcing the district to close all of its schools late Thursday. Classes were up and running as normal Friday, but that evening was when the flooding occurred.
The overflow of water, discovered about 6 p.m. Monday night, not only affected seven classrooms and a science lab, but left local residences with low water pressure or without water completely, according to an official at the Fallbrook Power Utility District.
This district serves about 9,000 customers.
The culprit was a weak welded joint on a 16-inch-diameter line running under Stage Coach Road. It failed after its bolts rusted out said Jack Bebee, an Engineer and Planning Manager for the water district.
Officials have not yet finished assessing the damage, and they are uncertain when classrooms will reopen. As a result, dozens of students will get their science lessons in backup classrooms.
Dale Mitchell, a superintendent of the Fallbrook Union High School District, said Friday’s leaks led to the most serious flooding at the school since the 1970s.
