    yes I know the ground does not perc very well out there and that's what they required for a 4 bedroom out.

    I will be using rock and gravel

    400' of line for the innovated system.

    my last question is when you are doing the 125' long line and the land slopes down how do you adjust for that.

    EX: it says 30" in the ground and say over 125' the land falls 2'. so do I keep it level so that the end is only 8" under the ground or do I step the line down?

    That soil looked nasty for sure. You have too find the contour grades of the land. For example if you look at a map with topo lines then the lines will be what you will dig your trenches too. If you have multiple lines it does not matter if each line is at a different elevation. The dbox will take care of that. You have to find level grade for each trench and then dig it too depth. The trench ha stoo maintain 30 inch depth.

    You dig your lines along the contour, not down the hill.
    If your not familiar with d boxes they have pre formed cut outs on all four sides.
    At that depth you will also need to buy risers for them.
    The 4" pvc sch 40 pipe coming out of your tank needs to run at a min. of 1% down hill to your first d box.
    Cut out the bottom hole in the d box to the leach line.
    Cut the hole in the d box from the tank, 4" above the top of your gravel in the leach field.
    Cut the hole, going out to the next line so the bottom of the hole is level with the top of your gravel.
    You want the line to fill with water then break over into the next line, the line from the tank wants to be 4" higher so it free falls into the d box. The boxes are tight with three pipe in them and you need to be able to put a cap on the line going to the fields on each line so that it can be capped off and rest if need be.
    Then run down hill to the next line. We have min. c/c distances so the next run would be say 8' c/c.
    Take your rod and paint out a level line across the contour for your distance. You should also take some 4" pvc with a clean out cap and place in the end of the trench vertically with some 1/2" holes drilled into the sides to be able to monitor the depth of water in the lines. This will let you know if that line needs to be capped off and let rest.

    so update on the septic system,

    I got the tank set in the ground and I've decided to go with the 400' of easy lay pipe.

    Im not a fan of it but I think its going to be the best and quickest for me knowing that it will all be in the back yard and only a riding mower will go over it.

    plus its going to be cheaper since I was going to have 2k just in rock!

    Do you mean EZ Flow pipe? Which one you using? How much they charge you for it? It averages about 5.50 a foot here for the 1303 and 4.60 a ft for the 1203.

    With you owning your own dump truck the gravel should be 10 a ton or less and you only need about 15 tons per 100 ft.

    nope that's the material cost. its ridiculous with 5 quarrys around they all are a monopoly. I could go 50 miles away and get it for 13 a ton but its not worth the time and fuel burnt to get it

    closest quarry to the farm is 20 miles
