What is the Chicago Sanitary and Ship Canal?
The Chicago Sanitary and Ship Canal is an artificial connection between the Great Lakes and Mississippi basins. During the late 1800s Chicago suffered severe water quality problems, and a consequently regular public health emergencies when sewage waste was drained into Lake Michigan. The sewage outflows were near to the drinking water intakes. To overcome the health problems, the flow of the Chicago river was reversed, and a canal built to connect the river to the Mississippi basin.
