PGSS has been closed for the rest of today and tomorrow due to a broken water main.
With no water available for drinking, toilets and fire protection, students were sent home after Tuesday's first period and those students who usually get to and from the school by bus were transported home by bus.
"It became apparent there was water on the surface this morning as school was opening," Marilyn Marquis-Forster, School District 57 superintendent, said. "There was further investigation from maintenance."
When it became apparent it was a big problem, excavators were called in and discovered the water main was broken, Marquis-Forster added.
"That's when it became apparent we would have to close the school," she said.
The water main will be repaired and it looks like the school will be opened Thursday but that will be confirmed Wednesday.
More information will be posted on the school district's website and will be sent through a messaging system to parents.
