    In Georgia wells usually run at $1000 for 1000 FT. You usually hit water at 3000-4000 FT (mine is about 4000), but I've heard of some going to 5000-6000. Just as a general idea for pricing.

    I have pretty good flow straight off my well at 22 GPM.

    If you have low flow a lot of people tie cisterns into the well(1500 Gallons from what I've seen out here) and run a pump station off of that.

    Wells r just not common here... I called today a drilling company. Not even one in my town... but they told me to look on our states water conservation website and I can type.in my property legal description and it will shoe me all Wells around my area and the depth.... I've herd a dollar a ft figure as well... not sure if that's went up or not... I'm always afarid though of spending that kind of money on a well Ans it not have good supply... wouldn't make me happy! Lol

And they were not there...... they use 2 metal rods though.... maybe I could get lucky and hit warranty at just a few hundred feet...lol I've got a creek behind me on the land...lol

    I don't have many issues dowsing. I spent a lot of time working on it this year and it has paid off.

    There is a reason that somethings work while others don't. One of the main reasons people have problems with their voodoo sticks is that they don't use them enough.

    I have posted the 7 Ps before, 2 Ps are different in locating.

    Glad Im not a well driller in GA. Round here they get $8 a ft plus around $7 a ft for casing when needed.

    1. Determine available flow/static pressure
    2. Identify the most taxed head, calculate pressure losses, and make sure you meet minimum head pressure.
    3. Don't exceed 5fps on pvc.

    The reasons to oversize pipe:

    1. Minimize pressure loss to achieve minimum head pressure.

    2. Prevent water hammer on long runs of straight pipe.

    If you do not have those two problems, your wasting plastic.

    You mean dynamic pressure.

    Start upstream of your meter and calculate the deductions from there.

    Meter deducts X amount of psi
    WYE Strainer deducts X
    Backflow deducts X
    Master Valve deducts X
    150' class 200 PVC deducts X
    Zone valve deducts X
    Lateral Piping....etc.
