| Yes, all those things occur. The main tile (its a mutual tile, not a county tile) rises about half a diameter so the next place north doesn't drain the tile dry. Its already down to about 20 feet by hand, put in clay tile in 1907, 103 years old.
The tile companies know how to apply tile properly, plastic probably won't live as long as the clay tile already has.
And in Iowa there are companies that clean tile when needed.
Besides silting in, tree roots, and critters can make a mess, so its best to avoid trees and to try to limit critter access to the tile, though it's hard to keep out mice and voles.
I think its safe to say that without tile and drainage ditches, most of the north half of Iowa and all the level parts of southern Iowa would still be swamp, not farmable most years. With just 40 inches average rainfall, it would look like Belize. Black dirt on top of an impervious clay layer. On my farm, on a knoll, where I wanted to build a house, I hit water at 3 feet, held up by that impervious white clay layer. I put in tile before digging the basement excavation that would otherwise have been a swimming pool.

Would drainage tile work in Alberta?
