Dirks Dozing & Excavating is exited to inform that we have installed our first sub-irrigation system! We installed this twenty acre test plot this spring just in time to plant corn. The three inch laterals were installed on fifteen foot centers at two feet deep. We use HDPE pipe for the water supply line and use a butt fusion machine to make the connections. This fusion process makes a tee or any other fitting as strong or stronger than the pipe itself. Anyone interested can call or leave us a message on our website.
