Handy Middle School reopened to students on Monday after power was restored to the building over the weekend.
There was no school for staff and students on May 17 after a diving brick went through a viewing window in the pool the previous day.
Bay City Schools Superintendent Stephen Bigelow said the pool flooded the school’s tunnels with several feet of water and caused mechanical and IT issues.
Transformers are also housed in the tunnels, with electrical lines, so power to the building was knocked out, including the IT system for the entire district.
Bigelow said “obviously the brick didn’t magically float over to the window” so an investigation is underway to see how exactly the window was shattered.
Insurance adjusters are also trying to determine the extent of the damage.
Bigelow did say the last day of school is June 7th, and that is still the plan, although there may have to be some temporary alternatives for things like food services.
"Thank you to Mr. Pfundt and his crew and Clements Electric for their hard work this weekend," the school posted on its Facebook page Sunday night.
