Site work for a civil project in Ames, Iowa. Completed plans call for site work for a water / sewer project.

This project will construct Edge of Field practices in Story County, consisting of saturated buffers and bioreactors that will treat existing agricultural tile outlets. A saturated buffer is an area of perennial vegetation between agricultural fields and waterways where tile outlets drain. Tile lines connect to a control structure, which distributes water laterally along the buffer. As water drains into the buffer, the living roots of perennial vegetation absorb water and nutrients, like nitrogen. A bioreactor is a buried trench on the edge of a farm field that is traditionally filled with woodchips. Drainage tiles outlet into the woodchips where bacteria convert nitrogen in tile water into nitrogen gas.
