Illinois Drought

Blandinsville

System Information

System Description

Blandinsville obtains its water supply from La Harpe Creek and uses two off-channel reservoirs, North Res. and South Res., for storage. Water is withdrawn from an intake adjacent to North Reservoir using a pump that is typically operated at 300 gpm. This pump may also be used to transfer water to South Reservoir, which is adjacent to the treatment plant.

Developments since 1989:

A new off-channel reservoir for additional storage was constructed in 1992. The community did not implement any mandatory conservation measures during the 2005 drought, but it often could pump only 7-8 hours per day during this period.
