River Flow Reversed to Solve Sewega Problem for Chicago.

The article discusses the construction of the Chicago Sanitary and Ship Canal in the 19th century to address concerns about sewage contaminating the city's drinking water. The canal, which is 28 miles long, was built to reverse the flow of the Chicago River and divert sewage away from the lake. The project faced challenges, including disputes over the classification of materials and labor strikes. The canal was completed in 1900 and later led to the construction of treatment plants for the growing Chicago metro area. The operation of the canal was transferred to the U.S. Army Corps of Engineers in 1930. [Extracted from the article]
