Reversing the Current: The Engineering Triumph of the Chicago River


In the late nineteenth century, Chicago was expanding at an unprecedented rate, transforming from a modest trading post into a bustling metropolis of over one million residents. However, this explosive growth brought a severe public health crisis. The city’s sewage and industrial waste drained directly into the Chicago River, which naturally emptied into Lake Michigan. Because Lake Michigan was—and remains—the primary source of drinking water for Chicagoans, the contamination caused catastrophic outbreaks of waterborne diseases such as cholera and typhoid fever. City leaders faced a dire challenge: how could they protect their drinking supply when their river was constantly carrying toxins straight into the lake?
