Jim Kirchherr takes a tour of an empty water tank and learns about the present and history of water treatment in the St. Louis area. The water in the area has always been drawn from local rivers and has a history of being murky and cloudy. This was not a health concern, but when the 1904 World’s Fair approached city leaders in St. Louis wanted to be sure that the water for both drinking and display was crystal clear. The system they put in place back then is still the basic system used today, although the process has been improved and modernized to fit the needs of the area.
