Crews have determined the cause of the flooding that turned the foyer at Millard North High School into a miniature lake on Tuesday.
A cap that had been placed on an abandoned storm drain line failed, said Rebecca Kleeman, a spokeswoman for the Millard Public Schools. That allowed water from Tuesday's heavy rains to rush in from the roof.
The cap was meant to be temporary, Kleeman said. It was installed in 2015 when work started on the school's $9.75 million project to build a new entrance and second-floor connector.
The contractor, Lund-Ross, "meant to come back with a better, more permanent plug," Kleeman said. "It was an oversight on a huge project."
The water broke through a tile and flooded an area near the school's Hall of Fame wall. Maintenance workers quickly cleaned up the mess, Kleeman said, and little damage was done.
The permanent plug should correct the issue. Kleeman said Lund-Ross has been very helpful and the work is covered under warranty.
Millard North is at 144th and Pacific Streets.
