Iowa Bioreactors

Iowa | Agriculture


ISG worked with a number of Iowa clients to design and construct bioreactors.


A number of sites across Iowa were ideal for innovative drainage solutions, particularly through the implementation of bioreactors. Below is a small snapshot of such projects.


Reutter Bioreactor – Boone County
Treating 36 acres, this bioreactor outlets directly to Drainage District 194 Main Tile. A field day open to the public was held to showcase the construction process and present the practice to landowners.

Van Ersvelde Bioreactor – Poweshiek County
This bioreactor was installed near an existing fence line and outlets directly to Little Bear Creek. Grinnell College is actively monitoring nitrate concentration, dissolved organic carbon, and water levels through the bioreactor. Treating 50 acres, the site hosted an August 2018 field day.

Campbell Bioreactor – Keokuk County

The largest bioreactor from the fall 2017 installations, the Campbell bioreactor treats 64 acres and is positioned parallel to an existing grass waterway. The landowner assisted the contractor with a successful installation.
