Charleston
System Information
System Description
Water is typically pumped from Lake Charleston, a low channel dam impoundment in the Embarras River, to the Charleston Side Channel Reservoir (CSCR), an off-channel reservoir, at 4,000 gpm before being relayed to the community's new 4.5 mgd treatment plant at up to 3,125 gpm. If necessary, two pumps can fill the off-channel reservoir at 7,500 gpm.

Developments since 1989:
A new treatment plant eliminated a chronic taste and odor problem in 2005. Several CSCR locations have received shoreline erosion treatment since 1991, and a sedimentation basin was built in its northwest cove. Eastern Illinois University implemented a conservation program 2006. There are plans to build an emergency connection with Mattoon.
Note: *Poor meter locations in old treatment plant may have overestimated production by 0.3 mgd prior to April 2005.
