Wikipedia EN Chicago Sanitary and Ship Canal
The Chicago Sanitary and Ship Canal, historically known as the Chicago Drainage Canal, is a 32-mile-long (51 km) canal system that connects the Chicago River to the Des Plaines River in Northeast Illinois, US. 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. The related Calumet-Sag Channel does the same for the Calumet River, 10 miles to the south, joining the Chicago canal about halfway along its route to the Des Plaines River.
The canal was built to solve a public health problem. Prior to its opening in 1900, sewage from the city of Chicago was discharged into the Chicago River and flowed into Lake Michigan. The city's drinking water supply was (and remains) located offshore, and there were fears that the sewage could reach the intake and cause serious disease outbreaks. Since the sewer systems were already flowing into the river, the decision was made to reverse the flow of the river, thereby sending all the sewage inland diluted with lake water, allowing flowing water to assimilate the waste load as it flowed through the canal, Des Plaines River and Illinois River.
The building of the Chicago canal served as intensive and practical training for engineers who later built the Panama Canal. The canal is operated by the Metropolitan Water Reclamation District of Greater Chicago. In 1999, the system was named a Civil Engineering Monument of the Millennium by the American Society of Civil Engineers (ASCE). The Canal was listed on the National Register of Historic Places on December 20, 2011.
