    My property is on a gradual hillside. On the uphill side I placed a shallow diversion ditch, but still have very wet soft ground. I believe the water is coming through the ground below the depth of the ditch I have (~1 foot). Would it be worth the time/money to trench down to ~ 4 feet and use drain tile?

    :blob3: Yes, you could lay a drain tile, or you could install a french drain. Some people around here say they are the same thing, but heres what it is. Dig a trench across the hillside in 2 or 3 places depending on how far the yard goes up and down the hill, and make it a depth of about 8 inches on one end and about 14 on the other. Go to the hardware store and purchase 4 inch solid drain pipe, that black plastic stuff, and lay it in the trench. at 4 or so points along the pipe , cut it all the way through. Get a drain that fits the pipe, they have these at lowes, home depot, etc. and put it on the pipe. MAKE SURE YOU GET ONE FOR AN END AND THE REST WITH AN IN FLOW AND AN OUT FLOW (bassically a "t" connector) Then run the shallow end with the pipe coming out of the ground at the edge of your property and backfill the rest. this makes the side soggy only if it will be at all.

    Love your town. Grew up in Rochester and did some sales work in your area a couple times a year.

    May I ask you some ?s that might help us help you?

    What's your rough budget?

    What are the dimesions of the area?

    Is there bedrock underneath?

    Can we see a picture?

    Having grown up in Endicott, my bet is you will hit slate after you dig more than 2'. I did a job like what you are describing at a friends place years ago. No offense, but you might want to give one of the local LCOs a call if you have to deal with the bedrock. I can recommend Northern Scapes for starters. I used to work for them back in the day.

    Is the wet area below your diversion ditch or above? What we would do is trench out, place in corrugated 4" pipe and surround with crushed stone. Then cover top foot or so with topsoil if you want grass.

    Feel free to PM me if you have any questions.

    Sorry this took so long.......

    I am not sure if HTML works but I will try to put my picture here....<img src= http://zcases.homestead.com

    I have circled in red the real wet area. You are looking uphill at this area, and the hill continues gradually past the treeline. I am thinking I will put the ditch right along the treeline, to the left right past the swingset and about 250' to my other borderline, not visible in the picture. There is presently a shallow diversion there, only ~6 inches deep, and I think the groundwater is running right through the ground under it. Even though the ground is quite bony I dont expect to have any real problems digging, of course I will be using a backhoe of some type. Probably one of the small track jobs for rent. Maybe I can stick to a budget less than a grand. So I think I will go 3-4' down and use perforated pipe/filter fabric/stone. I hope this will dry out the ever present swamp around the swingset.

    Thanks again to all reply-ers.

    Appreciate the pic.

    That doesn't look like much of a slope! Am I the only one who sees what looks like a low spot?

    I fear that any water getting in that area will stay there for a while. Might want to install that drain directly under this low area. Or create a burm on the high side of the area to direct water away before it gets there.

    This is all based on what it looks like to me in the picture. I could be wrong. Anyone else think the same?
