Johnson County Wastewater (JCW) is responsible for the safe collection, transportation and treatment of wastewater generated by our community. Wastewater is simply drinking water that has been used in businesses and residences.

There is no creation of water. We collect the water, treat it and release it back into nature where it can be collected, treated and used again. Our work ensures that our lakes, rivers, and streams remain free from disease-causing pathogens and pollutants that are harmful to public health and the environment.
