You need to know how much water you are using, how much the pumps are running (in hours per month), what make/model the pumps are and what horsepower. Then we can give you some idea whether you have the right pumps.
Also, what kind of controls do you have on the pumps?
If you have deep well pumps designed for high pressure that are pumping water into tanks that are at atmospheric pressure, or if you are throttling pumps in any way to operate at high pressure when they don't need to be, then you are wasting energy.
I will come back with an analysis later tonight.
