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

Aren’t you curious about what happens after you flush? You may be surprised to learn the science behind cleaning the water before we return it to our streams. 

Johnson County Wastewater is a vital community asset for Johnson County and the environment. We operate and maintain: 

• More than 5,500 above ground assets at six wastewater treatment facilities and 30 pump stations.
• Underground assets that cover a lot of territory with more than 2,200 miles of pipe and 55,000 manholes with an estimated replacement value of $1.7 billion.

The wastewater treatment processes that use a complex mix of microbiological, chemical and mechanical processes.
