NOTICE - August 2023:

  • Parking Lot Paving for the new Construction Trailer complex adjacent to 49th Street will begin in mid-late September.  Construction Staff will move into the new Trailer Complex following completion of paving

  • Following the project, the plan for the area is to restore it as green space with a landscaped berm, closer to where the original fencing was located. 

If you detect odors we would like to know so we can address them.  You can fill out an odor complaint form by clicking on the “Odor Complaint Form” button. This form notifies Operations & Maintenance staff and top leadership directly. 

Nelson Wastewater Treatment Facility Improvements Project

Nelson Complex Wastewater Treatment Facility (WWTF) is Johnson County’s oldest treatment facility, and its service area is comprised of two main tributary basins - Turkey Creek (SMTC) and Mission Main (MTM1).


The service area, located in northeast Johnson County, is approximately bounded by 47th Street to the north, 95th Street to the south, Pflumm Road to the west, and State Line Road to the east. Metcalf Avenue roughly divides the two basins, with Turkey Creek to the west and Mission Main to the east.

The improvements project will upgrade the treatment facility in order to address aged and deteriorating infrastructure and to comply with new regulatory requirements.  

Information pertaining to the project, including schedules and activities, will be available on this site and updated as the project progresses.
