GRP, MountainBiker is right that we do not know were your water table is. Where I live in Florida it is 10 feet deep. It’s almost all coral rock. I owned a house five years ago in the gulf in Florida and the water table was 8 feet all sand, very easy do make a well but needed a well pump because the water is in the sand so you need to power of the pump to pull the water out. He is right if your well is not to deep add a hand well pump. They do make the hand well pumps for deep wells but they are not cheap.
