In the late 1840s, Chicago was growing rapidly and was plagued with health issues: the majority of the city sat at water level, which meant water was unable to drain out of the city. The problem was fully realized in the summer of 1849, when a cholera epidemic struck Chicago. In response, the public held meetings and demanded that the City Council rid the city of filth. The legislature of
Illinois created the Board of Sewerage Commissioners on February 14, 1855, leading to the appointment of Assistant health officers to aid the cleanup, and by August the Council resolved to build a sewage system. Chesbrough was appointed engineer of the Board of Sewerage Commissioners because of his work on Boston’s water distribution system. From an engineering standpoint, the main problems were moving waste water out of the city and keeping it from polluting the city's drinking water supply, drawn from
Lake Michigan. His plan was twofold: first, to build the sewer system above ground, and then raise all of the city buildings (see
Raising of Chicago) as much as ten feet using an elaborate system of jacks. The new sewer system featured innovations such as
manhole covers, which eased access to and cleaning of the sewers. However, sewage still flowed into the lake and polluted the city's drinking water. In 1863, work began on a two-mile
Chicago lake tunnel, sixty feet under the lake, out to a new
intake crib. that would draw cleaner water farther from the city. Eventually, however, sewage water seeped all the way to the crib, giving Chesbrough a third chance. Plans were made to reverse the flow of the Chicago River, leading water away from Lake Michigan and carrying Chicago's sewage into the
Mississippi River. In the late 1860s, the
Illinois and Michigan Canal was dredged and deepened to expand its ability to handle the city's sewage and move it away from the lake, but continued population growth quickly outstripped the canal's waste management capacity. The project of reversing the river was completed after Chesbrough's death by the Sanitary District of Chicago (now
The Metropolitan Water Reclamation District), created in 1889, which undertook the construction of the
Chicago Sanitary and Ship Canal. Chesbrough died in Chicago on August 18, 1886, and was buried at
Graceland Cemetery. == References ==
