One of my projects before planting grass in the spring is to bury all of our downspout extensions. Something I always intended to do at our old house but never got 'round tuit [img]/forums/images/icons/frown.gif[/img]

Our land is essentially flat although there is a nice pitch away from the house in all directions. No trees, thus no leaves to worry about in the gutters (at least for a very long time).

I've seen black flex-pipe in solid and perforated. Rigid pipe in both. Many questions... Which pipe? How deep? Terminate in drywells or come back up to the surface? If surface, what kind of cover?

As I am just starting to plan this project please share all of your experiences both good and bad. Thanks [img]/forums/images/icons/smile.gif[/img]
