I assume I'm stupid and that there's actually a good reason for it, because on the surface it seems like a dumb idea to use pipe like that with ridges that beg for sticks to jam up and start a clog vs. smooth pipe.
So, why are so many drainage pipes out there corrugated rather than smooth?
I got water issues and usually just redig a trench to let it run off. I'm considering burying a pipe and hoping I won't have to dig it up in a year or two to unclog it. Considering another alternative with pouring a concrete ditch of sorts as well. Not a long run, but can't go too deep either.
