Designing a subsurface drainage system

Improved surface and subsurface drainage is necessary for some Minnesota soils to optimize the crop environment and reduce production risks.

To assure an effective and profitable system, it's important to couple a good design process with the thorough evaluation of such on-site factors as soil type, topography, outlet placement and existing wetlands. This, and a quality installation will ensure a drainage system that will effectively perform for many years to come.
