Students at Dallas Elementary in Dallas Township race to school buses for an early dismissal on Monday after the school district buildings started to experience water pressure problems. All four schools at the Dallas School District campus were dismissed early when pressure dropped rapidly in the morning. District workers initially thought a pump that brings water in from a nearby tower had stopped working, but the problem turned out to be related to a water main line break over the weekend somewhere beyond the campus that had caused the tank to drain, Superintendent Frank Galicki said. The water company ‘didn’t think it would affect the water tank, but it did,’ he said. The pressure was later restored.
