Illinois Drought


System Information

System Description

Water from the Kaskaskia River is pumped to the South (Old) Reservoir at up to 450 gpm. This water then is conveyed to a 1 mgd treatment plant below the South Reservoir dam via gravity flow. The Sparta NW Strip Pit is also available as a 900 gpm emergency source.

Developments since 1989:

The Sparta NW Strip Pit was connected to the system in 1989 to replace the North (New) Res., which has been used only once (in 2002) since 1994. The river intake now has two alternating pumps. A new 1.8 mgd treatment plant will be built upstream of the dam as the current one is situated in a floodplain right below it.
