You will likely need three 200 foot deep boreholes for this to work appropriately. Drilling bore holes is NOT cheap! Here in Oklahoma it is about $1500 per bore hole.
You are drilling a water well when you drill a bore hole . . .
If you have the land, drilling a well may be a LOT cheaper than you think.
