    French drains are not standardized they can be installed in several different ways using different kinds of methods and materials. The most common way is to price it out by totaling all expenses + your profit percentage. The problem hear is you never done it before so you will not know your accurate labor cost your best guess could be way off. In this situation you can ball park the cost and bill for time and materials then the next drain or similar job will be easier to cost out.

    i do it pretty much just like that pic, but i add landscapers matting down in the trench before the stone and perf pipe, pitch the pipe at least a inch every 4 ft

    wrap the pipe in it, then line the trench with it install the stone then cover the stone .this way their is no dirt contact with the pipe and stone. you do not want dirt migrateing into the stone.

    Do you usually dig the trench yourself??
    If you use a machine which one?
    We're in michigan how deep and wide should the trench be
    because Imagine she wants to use it in the winter....

    Thankkkksss

    Sounds like you are not looking for a french drain. You are looking more for a dry well to catch the pump output. Size would depend on how much water you might be talking about.

    Um.. thanks :rolleyes:

    Yeah well kinda.....
    The pipe right now goes all the way to the street i think its like 12in. below ground.
    So im going to cut the pipe and just dig a 20' by 6'' trench then fill it with rock...
    then plant (as i quote her words) "Plants durable in all/most conditions"

    So its not as bad as i thought it would be...

    HOW MUCH WATER WILL SHE BE PUMPING TO IT, I PUT ONE IN AT MY HOUSE TO KEEP MY BASEMENT DRIER,(had a dampness problem) RAN ALL MY GUTTERS TO IT OFF THE BACK OF THE HOUSE, AT THE HIGH END I HAVE ABOUT A FT OF STONE ON TOP OF MY PERF PIPE, AT THE DEEP END IM DOWN AT LEAST 5 FT, ALTHOUGH IT SOUNDS LIKE YOU DONT NEED ANYTHING TO THAT EXTREME.

    I USED A KUBOTA BX22 TO DO IT WITH A 8" BUCKET ON THE HOE.
