The purpose of National Backflow Prevention Day is to acknowledge the importance of backflow prevention, educate the public on how this life-saving technology is used, and to recognize the water quality professionals responsible for installing and maintaining backflow preventers.

National Backflow Prevention Day day commemorates the tragic backflow incident on the same day which occurred in Chicago in 1933. That summer, visitors traveled from points near and far to attend the World’s Fair. A water supply was shared by two major hotels that were filled to capacity with tourists. Unaware of the dangerous cross connections in their plumbing system, the two hotels unknowingly allowed amoebic dysentery to spread prolifically throughout their rooms, contaminating the water consumed by their guests.
