I saw this stuff at the construction supply place we go to a couple of weeks ago and thought it was a good idea.
I thought when i saw it that it would be perfect for a diy type project.
It looked like this stuff.

You can also line the trench to keep silt out of the stone and get a longer life. I always use crushed washed stone. That sounds like a really wide trench, any reason to make it so wide? I usually do 1' x3' which is good because my bh bucket is 1 foot and i have less stone to buy and dirt to move.
I used 1 1/4 crushed rock, the same rock used for septic system leach fields. works great.
A lot of good opinions here. My two cents, I would go with 3/4"-1" crushed stone as if my memory is right, that size stone holds the most water per cu. ft. Bed the pipe in 3", put a foot or so on top, and then cover before backfill with filter fabric, or 15# felt (tar paper) or as someone suggested, an old time solution-good layer of cut hay. This plus a buck eighty will get you a medium coffee at dunkin donuts or for you Mainers, this plus 99 cents will get you the same coffee at Cumbies!
My mistake, I figured I had to be missing something.Quote:

I think you need to get your bifocals adjusted. His post #1 says 12 inches wide not twelve feet.Quote:

Thought he said 3' see that it's 1' it now... 12' would be one heck of a french drain!Quote:

This was dug about 45 or so feet long leading away from the barn corners started out about 24 ~ 30" deep and ended about 5' deep out at the ends.
I had a bunch of broken or chipped cement blocks that I laid out into the bottom of the trench out in the deep area. I have creek that has a lot of sand stone shale type crushed type run in it. it is seasonal and dry much of the year so I used the larger flat rock to lay out on top of several courses of the block tossed in haphazardly.
I then dropped in a layer of the inexpensive landscape fabric and more crushed smaller stream crusher run sandstone with the pipe sleeved on into the trench and tossed in a cover of the creek run and added a 2nd layer of the fabric and stone & sand mix up with a last layer of fabric and dirt/ seeded grass and has worked like a champ for 5 ~8 or so years now.
cost was mostly fuel w a bit for the fabric so time was a weekend work give or take.
The cement blocks have a lot of dead open space to fill w water so it can absorb a LOT rather quickly. 4'down at my place is a very permeable layer of glacial rock about 6" deep so that helps and keeps it draining quick.
