The line from the power source would have to be underground as there is a field (often tilled) in between. Thus, I would rent a trencher. So picture barn at top of hill (A) as power source. Line goes down steep hill, crosses a creek, goes up and over another hill (B) and down again toward pond that is prob smaller than 1/2 acre and less than 3 feet deep. 1/4 of a mile distance separation is a total guess. Tubing is easy to figure costwise if distance is figured. What is the cost of the pump and does it just plug in? Is freeze guard necessary? How do I figure the correct diffuser and how much am I looking at cost wise there? Never knew this could be so complicated, but what isn't I guess?!
