More than 100 million people are expected to watch the Super Bowl this Sunday.
Researchers at the University of Arizona say there is an urban legend about what would happen if all those people got up to go to the bathroom during halftime -- and flushed -- all at once.
The legend says there could be a major infrastructure failure. Jean McLain, the associate director at the Water Resources Research Center -- a unit of the University of Arizona's Cooperative Extension -- says this failure would never happen.
“We do so much water recycling here in Arizona, the wastewater treatment plants are designed to handle the super flush. The flush gets treated, and the water recycles back into the water supply,” McLain said.
McLain says she was touring a municipal wastewater plant and the highest flow of the year does happen during halftime at the Super Bowl.
