One of the biggest Super Bowl myths is that the sewage systems of major cities are on the verge of collapsing due to millions of toilets being flushed at half-time. On average, the amount of water being flushed during half-time is equivalent to seven minutes of water flowing over Niagara falls -- or 90 million toilets being flushed. While that is a hefty amount of water flowing at once, municipal sewage systems are equipped to handle this kind of usage.
COULD IT HAPPEN?
During the 1984 Super Bowl XVIII in Salt Lake City, a water main ruptured in the city causing quite a stir. People were quick to relate this incident to the big flush myth, but public officials stated this was not an unusual occurrence for their old plumbing system. No other major sewer system incidents have been recorded on Super Bowl Sunday.
So flush away with no fear and GO HAWKS!!!!
