I think what he means is what are the casing size, depth and GPM produced from typical wells in your area near the pond.

For instance here, a typical house well has a 4" casing, and will produce anywhere from 10-30 gpm from a well that is between 90-110 feet deep. Agricultural wells (center pivot) can be up to a 16" casing, and can supply over 2,000 gpm. Well depth is still in the 90'-110' range.

As for electricity, I'm assuming you have 220v-240v single phase available. You need to measure the actual voltage to determine where you stand. For instance, here I have 243 volts.

If you have 3-phase, consider yourself lucky. You can save a bunch on electric costs!
