If you have a lift station or control structure, you can keep a lot of that excess moisture in the ground for your roots to use later. Can you give us a range on cost for drain tile projects? A fair range is $600.00 - $1,000.00 an acre. The variance depends on the slope of your land (grade), spacing, whether you need a lift station or can have a gravity outlet, and distance to your out- let. Does drain tile work on all types of soil? Yes, however pipe type and spacing will vary depending on if you are in a tighter clay soil or in a sandy gravel type sub- soil. When is the best time of the season to install drain tile? Summer is the ideal time, when you have drier conditions to work in. It’s also cheaper to have a con- tractor tile early harvested crops or PP ground. Roger Ellingson (right) with his son, Derrik “Spike” Ellingson in 2016.
