Its a tile drain. Dig hole insert pipe, Plan out your drainage right the first time to get the best bang for your buck. I prefer the socked ones. Most pipes(especially older ones) collapse either from weight, being compromised ect.... If you buy it, see if they recommend gravel. You could do a true french drain and just dig trench, pour in gravel and cover with a few inches of dirt. I would put some sock material(filtration paper) under dirt. And make sure you seal any joints in the pipe connections.
