Aerial view of Phase II of the McCook Reservoir under construction in 2023. The Tunnel and Reservoir Plan (abbreviated TARP and more commonly known as the Deep Tunnel Project or the Chicago Deep Tunnel) is a large civil engineering project that aims to reduce flooding in the metropolitan Chicago area, and to reduce the harmful effects of flushing raw sewage into Lake Michigan by diverting ...
These Wellhead Protection Programs must specify the duties of State agencies, local governmental entities, and public water supply systems to develop and implement wellhead protections. Identification of the area that needs wellhead protection must be based on the hydrologic and geologic information on groundwater flow, recharge, and discharge.
It serves as a channel between the Little Calumet River and the Chicago Sanitary and Ship Canal. It is 16 miles (26 km) long and was dug over an 11-year period, from 1911 until 1922. The Cal-Sag Channel serves barge traffic in what was an active zone of heavy industry in the far southern neighborhoods of the city of Chicago and
Groundwater banking is a water management mechanism designed to increase water supply reliability. [1] Groundwater can be created by using dewatered aquifer space to store water during the years when there is abundant rainfall .
Sustainable groundwater management: the management and use of groundwater that can be maintained without causing an undesirable result. Undesirable results include any of the following: Persistent lowering of groundwater levels; Significant and unreasonable reductions in groundwater storage; Significant and unreasonable saltwater intrusion
The State of Illinois created a drainage commission for the Chicago area in 1852 to deal with a potentially contaminated city water supply. [2] The commission made the master drainage plan in 1856. The master drainage plan was centered around raising the city by 3m and constructing new sewers that drained into the river and not the lake.
Use of groundwater, especially for irrigation, may also lower the water tables. Groundwater recharge is an important process for sustainable groundwater management, since the volume-rate abstracted from an aquifer in the long term should be less than or equal to the volume-rate that is recharged.
Groundwater is also used by farmers to irrigate crops and by industries to produce everyday goods. Most groundwater is clean, but groundwater can become polluted, or contaminated as a result of human activities or as a result of natural conditions. The many and diverse activities of humans produce innumerable waste materials and by-products ...
