A reversal flow of the Chicago River into Lake Michigan would have a negative impact on navigation and on the quality of Lake Michigan water, which is the source of drinking water. [5] Chicago's raw sewage in the river is normally carried upstream toward the Mississippi River which flows south towards the Gulf of Mexico.
The Chicago Sanitary and Ship Canal, historically known as the Chicago Drainage Canal, is a 28-mile-long (45 km) canal system that connects the Chicago River to the Des Plaines River. It reverses the direction of the Main Stem and the South Branch of the Chicago River, which now flows out of Lake Michigan rather than into it.

In 1892, the direction of part of the Chicago River was reversed by the Army Corps of Engineers with the result that the river and much of Chicago's sewage flowed into the canal instead of into Lake Michigan. The complete reversal of the river's flow was accomplished when the Sanitary and Ship Canal was opened in 1900.
Two important early projects included the reversal of the Chicago River, designed to carry wastewater away from Lake Michigan, and the construction of the Chicago Sanitary and Ship Canal in 1900 which aided in the flow of water away from Lake Michigan, the source of the region's drinking water.
Plans were made to reverse the flow of the Chicago River, leading water away from Lake Michigan and carrying Chicago's sewage into the Mississippi River. In the late 1860s, the Illinois and Michigan Canal was dredged and deepened to expand its ability to handle the city's sewage and move it away from the lake, but continued population growth ...
