If concerned about the noise and considering the distance to the pond. I would suggest (based on the noise of my two Kasco pumps) I would run some elec to a new small built shed or something like a well house (away from the bedroom window) where I would put the pump and then run rolled tubing to the pond. Cost for a real small well house I think would still be cheaper than elec line run to the pond. Or at least something to look at for comparing cost.
