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.
