Tile drainage has been practiced on may soil textures. Sandier soils can be drained with deeper, widely spaced tile, but tend to need sock filters to prevent soil particles from entering the tile. Soils with a higher clay content can also be drained but require tile to be placed shallower and closer together. A typical design for a Fargo clay or Clearwater clay loam soil might be a depth of 4 feet with a spacing of 25 feet, whereas tile spacing for a Ulen fine sandy loam would be closer to 100 feet. Soils where shrinking/swelling clays or peat predominate may need special consideration with regard to tile drainage.
