I've got a place on a hillside that was never leveled properly; quite the opposite, when it rains water pools up around the foundation of the buildings, instead of flowing away. I hoping that rather than regrading the entire hillside property, I can lay this perforated pipe (in the lowest area), just below the surface with some stone around it solve my problem. I won't really know until I get the pipe laid and I get a heavy rain (it could be months, as I live in Arizona, and it's only a problem during the monsoon season, 6 months away). I was initially going to lay this in 12' sections, but after talking to a Home Depot rep, he advised that long solid sections were easier to deal with as you didnt have to keep the joins connected. He also thought that the continuous pipe would drain fast accumulating water better than jointed sections. I took his advice, and you can see what a 100' section looks like below. It really is not that heavy, a 100' probably about 25 lbs. I started by laying it out, and I probably have 20' extra. I'll be digging a 1'x1' trench, putting 1" base gravel at the base then laying the drain pipe and covering it with 1.25-1.5" of pebbles. In the end I want it to look like a river. But I have some work ahead to get that done. I'll update this once I get a big soaking rain, but I'm pretty confident this is a proper solution.
I found that the pipe did not straighten quite as easily as I hoped, but it straightens out better once it was exposed warmer sunlight. The pipe is pretty dense and is not easily crushed, I don't see any way that the buried pipe could be damaged. The corrugation of the pipe helps to strengthen it.
