About Us: Johnson County Wastewater Treatment Plant Tours

The water’s fine — once we’re finished with it!

Come on – admit it. Aren’t you the least bit curious what happens when you flush? You might be surprised to learn the science behind cleaning the water before we return it to our streams.

Johnson County Wastewater (JCW) is big business.

  • Above ground, there are more than 5,500 assets at six treatment plants and 30 pump stations
  • Underground assets are even bigger, including more than 2,200 miles of pipe, and 55,000 manholes with an estimated replacement value of $1.7 billion.
  • The wastewater treatment processes use a complex mix of chemical, mechanical, and microbiological processes.

Intrigued? Come hear from our experts and tour a wastewater treatment plant. Employees who operate and manage the plants will show you step by step how we clean used water.

To request a tour, please complete our online form.

Note:

  • Tours are free and generally last 60 to 90 minutes.
  • We prefer groups of five or more. Groups of more than 20 may be split into two groups.
  • There’s no minimum age for participants, but groups with several young children will need more adults to help supervise them.
  • Participants should wear appropriate footwear, closed-toe shoes with flat heels.

Please provide us with as much advanced notice as possible.

Plants are located throughout the county, and we’ll work with you to choose a location for your tour.
