An 8-ha cabbage farm in Germany was looking for ways to improve water surface drainage especially in the wet season where the area experiences heavy rains. The farmer was also looking for a solution that will move as little earth as possible.
The design calls for the field not to drain to the South and Southwest side of the field as there is always another crop planted there. An existing channel along the North boundary can be used as the exit point of drain water from the field. Water can also drain to the East where there's a ditch in front of the road.

A ridge subzone was used to prevent water from exiting in the South and Southeast area, the resulting earthworks was 188 m3/ha (laser level design results to 485 m3/ha). OptiSurface saved more than 60% earthworks compared to traditional laser level designs.
