May 19, 1909: Municipal Journal and Engineerarticle. Disposal of Chicago’s Sewage. “The greatest sanitary undertaking the world has ever seen is the work being done by the Sanitary District of Chicago in securing a pure water supply and a disposal of the sewage from this mammoth city. Prior to the beginning of this project, all the sewage from the city was emptied into Lake Michigan, either directly or through the Chicago River. At the same time the water supply of the city came from the same lake and the intake cribs were only a few miles from the sewer outlet. Consequently, it was not surprising that the typhoid death rate was almost the highest in the country. While the· work is not yet completed, and there still remain a number of sewers emptying into the lake, conditions have been so improved that the City of Chicago had one of the lowest typhoid death rates, during the past year, of any city in the United States. Dr. Evans, Health Commissioner of Chicago, states that 16,299 lives have been saved during the past eight years by the improvement of the water supply due to the drainage canal.”

Commentary:The greatest in the world. Chicagoans have never been shy about using hyperbole to describe their public works. It is true that the typhoid fever rate was dramatically decreased due to the Drainage Canal. But, it would take the installation of chlorine 1911-1917 to break the Sewer Pipe, Water Pipe Death Spiral.
