Combined Sewer System. The change in the river's water flow was estimated to provide enough treatment-by-dilution for up to a population of three million. [1] However, in 1908, it became clear to the Chicago Sanitary District that the city’s population was continuing to grow and that the population would soon exceed the treatment capacity that the canal offered.
These seven plants range in capacity from 1.44 billion gallons per day at the Stickney Plant to 4 million gallons per day at the Lemont Plant. A water reclamation facility usually contains two treatment plants. One is for processing the wastewater while the other is for treating the solids captured during the first process.
The plant was constructed in the 1960s and began functioning in 1968. [1] The plant was renamed after James W. Jardine (1908-1977), a 42-year city employee, who served as water commissioner from 1953 until his retirement in 1973. Shortly thereafter the Ohio Street Beach was formed in the bay created by the
The term is used extensively in U.S. water pollution law (i.e. the Clean Water Act), regulations and programs. [1] [2] Many POTWs were established or expanded with grants or low-interest loans from the U.S. Environmental Protection Agency (EPA). [3] There are over 16,000 POTWs in the U.S., serving 75 percent of the total population. [4]
The plant was under construction for many years, slowed by the Great Depression. Its construction was approved in 1930 and the plant began operation in 1947. [2] Water is drawn from a crib in Lake Michigan that has an intake about 20–30 feet below the surface of the lake and is then drawn through a tunnel below the lake bed to the treatment plant, and then put through several steps to filter ...

Point source water pollution comes from discrete conveyances and alters the chemical, biological, and physical characteristics of water. In the United States, it is largely regulated by the Clean Water Act (CWA). [1]

The rapid filling caused seepage. By 1844 the Metropolitan Buildings act simply required new buildings to be connected to street sewers. [9] The tidal nature of the Thames did not help the matter. A similar situation was occurring in the US. Water consumption was increasing, for example in Chicago the per capita water consumption was 33 gallons ...
