Illinois regional water guide

Bloomington, Decatur and Springfield

Central Illinois markets spanning reservoir-fed systems, groundwater systems and large municipal utilities, with source and treatment practices that differ sharply by community.

Regional context

Use the regional hub, then verify the exact property

Central Illinois markets spanning reservoir-fed systems, groundwater systems and large municipal utilities, with source and treatment practices that differ sharply by community. The city pages below identify provider and source-water research starting points, but the current bill and PWSID remain the decisive identifiers.

Do not treat the metro as one water system. Communities within the same labor market can use Lake Michigan water, groundwater, river water, reservoirs or purchased supply from different wholesalers.
