Sanitary Sewer System Maps 

Maps of Johnson County Wastewater's sanitary sewer system can be viewed on the Johnson County AIMS Mapping System.

Johnson County Wastewater District Enlargement

All areas served by sanitary sewer mains under the jurisdiction of Johnson County Wastewater must be within the legally-created Consolidated Main Sewer District (CMSD). If the project area is not within the CMSD, the property owner will need to petition for enlargement into the CMSD. To identify whether a project area is within a Johnson County Wastewater CMSD area:

  • Use the AIMS mapping link directions above.
  • Select the “JCW Sewer Districts” box under the “Utility Layers” directory.
  • Then select “Redraw” to display. The Johnson County Wastewater CMSD areas are cross-hatched in yellow. If the project area is not within the Johnson County Wastewater CMSD, it may be an area that is currently in the department's planning or design/construction process.
  • To determine if the project area is in process, please select one of the Status of Proposed Districts and Study Areas Map.
