Water well electric source
Assuming you're in the US, what you'll need to do is the following (an electrician might be a good idea for some of this)


Mount a pole near to where the pump is. A pressure treated 4x4 would work for this
Mount a meter box. If you're doing this yourself, you can sometimes find these with the mast pre-attached and utility ready
Attach a breaker box to the meter. There's a lot of these with only a few breaker slots (think a 100 amp panel)
A GFCI breaker for however many amps the pump draws. My bet is a 20 amp would do
Thick enough UF wire and conduit to reach to the pump. 12-2 would be sufficient if 20 amps was for the previous step


Once this is all set, have the utility come out and connect to the box and install a meter. And that's it.
