"After significant rainfall, I flew up in my plane and got some pictures. As far as you can see, ponds are gleaming in everybody's field. I looked into my field which I have just completed and there wasn't one pond standing on that field."

Problem

The client is in Northwest Illinois and operate about 3000 acres, most of them tiled but still experience ponding issues.

The Existing Topography shows the low lying areas can clearly be seen  and the mini furrows (about 2 inches) created by machinery traffic exacerbates the ponding issue as confirmed by the Drainage Analysis below.

The field is separated by a road so they were designed independently, one on the north and the other on the south.

An OptiSurface 2Way was used to design the field.  This surface type lets water drain in along the direction of the furrows then draining at the ends or a defined cross drain.

Ridge subzone were added to define the high points in the field and valley subzones for the drains. The natural topography of the field was considered in placing these special subzones which resulted in low earthworks.

Conclusion

The design shows how to design with OptiSurface 2Way using ridges and valleys. This allowed water to exit to one point and eliminated all existing pipe inlets in the field. Total earthworks ended up at 95 yd³/ac (180 m³/ha).

Jeff was very happy saying:

Everything I have OptiSurfaced, I haven't had to replant anything (due to drown outs). That's pretty cool!

I've also got rid of dozens of surface drains (inlet pipes).
