  • Chicago begins flushing waste into Mississippi River system

    Beginning in the 1850s on an informal basis, and in 1871 on a formal basis, Chicago flushed its wastewater into the Mississippi River drainage system by reversing the flow of the Chicago River. With continued growth, sewage treatment works became necessary to conserve the lake water quality.

  • Rainstorm washes sewage in Chicago River far into lake

    During a tremendous storm in 1885, the rainfall washed refuse from the river far out into the lake (although reports of a 1885 cholera epidemic are untrue), spurring a panic that a future similar storm would cause a huge epidemic in Chicago.

  • Decision made to reverse the flow of the Chicago River

    By 1887, it was decided to reverse the flow of the Chicago River through civil engineering. Engineer Isham Oliver noted that a ridge about 12 miles from the lake shore divided the Mississippi River drainage system from the Great Lakes drainage system. A plan soon emerged to cut through that ridge and carry waste water away from the lake, through the Des Plaines and Illinois rivers, to the Mississippi River and the Gulf of Mexico.

  • Sanitary District of Chicago created

    Sanitary District of Chicago created
    The Sanitary District Enabling Act of May 29, 1889, established the District with the purpose of managing water supply and wastewater issues. Two important early projects included the reversal of the Chicago River, designed to carry waste water away from Lake Michigan, and the construction of the Chicago Sanitary and Ship Canal which aided in the flowage of water out of Lake Michigan.

  • Canal links the Chicago and Des Plaines rivers

    The canal, linking the south branch of the Chicago River to the Des Plaines River at Lockport, was completed in 1900. The rate of flow is controlled by the Lockport Powerhouse, sluice gates at Chicago Harbor and at the O'Brien Lock in the Calumet River, and also by pumps at Wilmette Harbor.

  • North Shore channel completed

    The North Shore Channel is a drainage canal built between 1907 and 1910 to flush the sewage-filled North Branch of the Chicago River down the Chicago Sanitary and Ship Canal. The canal drains out of Lake Michigan in Wilmette, near the Bahai House of Worship, and connects to the North Branch at the junction of several North Side community areas.

  • Chicago Flood fills downtown underground

    On April 13, 1992 the Chicago Flood occurred when a pile driven into the riverbed caused stress fractures in the wall of a long-abandoned tunnel of the Chicago Tunnel Company near Kinzie Street. Most of the 60-mile (97 km) network of underground freight railway, which encompasses much of downtown, was eventually flooded along with the lower levels of buildings it once serviced and attached underground shops and pedestrian ways.
