Illinois regional water guide

Southern Illinois and the Ohio-Mississippi Confluence

Southern Illinois communities served by reservoirs, regional surface-water systems, municipal wells and river-influenced supplies, with important cross-border ties to western Kentucky.

Regional context

Use the regional hub, then verify the exact property

Southern Illinois communities served by reservoirs, regional surface-water systems, municipal wells and river-influenced supplies, with important cross-border ties to western Kentucky. 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.

Regional connection

Southern Illinois and western Kentucky share a regional footprint

Paducah, Metropolis, Cairo and surrounding communities are connected economically, but every property must be matched to its own state, utility and water report.

Treatment planning

Match system design to the verified water problem

Regional information organizes the search. Property-level testing, plumbing conditions, peak flow and the exact certified treatment claim determine the final system.
