If your are far from bedrock then you will be ok. But if the rock is close then you are screwed and would have to drill through the rock. If you have a large deep dirt/clay base then keep driving that thing as far as you can. A friend put one in and his works great for a hand pump but the well points are not enough for electric pumps as they go dry and cant keep up with a high volume pump. You should be fine just don't have bad luck and put it right over a big rock!!!
