French Drain Project.

Here's pics of my latest project. In order to cut off some of the water coming off the hill towards my house, I dug a trench 12" wide by aprox 150' or so. It ranges in depth from 20" to 40" obviuosly sloping toward the rear of the house. I used 1 4" perf. pipe wrapped in a sock that ran the length of the ditch in a bed of #57 river gravel about 3-4" deep. I covered the pipe with the #57 gravel to within 1-2 inches of the original grade. Here's some pictures hope it's not boring. The NH TC24DA and 756C hoe saved a lot of work!

A little "jog" to catch the spouting line. This was run through solid line separately in the same trench.

This is facing towards the rear of the house were the grade goe down hill.

Sorry there were no pics between the open trench and the finished project but mother nature was on the way. Here is just after being done. We ended up with 2 inches of rain in about 45 minutes. This usually would have been a river and had standing water, however this project ended all of that.

Another shot. This worked pretty good, in fact like a dumb a** I went out in the middle of a nasty T-storm to check the end of the pipe and it was flowing very well. The pipes sticking up every 20' will be for surface drains/grates after the grass returns and I get the top soil moved in and the swales made.

Great project, MegaMe, and thanks for including the pictures. I assume the sock is to filter fine sediment?

I hired a contractor to do install a couple culverts and a "grassed waterway" last year. The day after he installed it, we got about four inches of rain in 24 hours! I was like a mother hen, out there checking things out in all kinds of weather. I was routing water into the woods. I was very concerned about slope (even put a slight adverse grade in) because I didn't want to initiate any mass failures of the hillslope with the additional surface water. So far things have held up great, but I know that feeling of wondering how it's working.

I may still end up doing some trenching and french drain installation so I really appreciate your post. Stay dry!

Great looking job, Mega. Reminds me of my own project I did on my house in the burbs about 15 years ago. This house sat on a downhill slope several feet below street grade, and the old drainage system (sched. 40) had failed. I rented a trencher (before my tractor days), and put in the black flexible drainlines with about 10 catch basins. My neighbor, an engineer, came over when I was about 80% done and warned me that this system would never work. Forgot why. It worked well for the 9 years I owned that home.

Yes the sock according to the manufacturer is supposed to filter out the sediment.

Check out ADS-Pipe, I spent a lot of time there researching!

I bought the pipe at TSC.
