Hundreds of students in Daly City stayed home from school Tuesday due to a campus plumbing problem.
Classes at Westlake Elementary School were canceled due to the emergency plumbing issue, which affected all school bathroom facilities.
"We couldn't have student and staff come to school and not have any facilities for them to use," Jefferson Elementary School District Superintendent Bernie Vidales said.
Vidales said he decided to cancel classes and after school programs on Tuesday after sewage started to back up and flood the bathrooms.
"Anytime we need to cancel school it's a big inconvenience, not just for our staff, but our students," Vidales said. "It's a day lost for learning and the routine. We took it very seriously."
All students and parents received a call from school officials in the morning to notify them classes were canceled.
Plumbing crews spent the day unclogging the backed up sewer system and also disinfected the bathrooms.
If for some reason pipes back up again this week, Vidales said the district will bring porta potties and continue classes.
