I guess it wasn't terrible, the usual Bill for this vacation spot is like 50$ a month. I wanna say I ran it on/off for a few days, and then like 5 straight days in a row. If I remember correctly the bill that month was like 150-ish. So it cost maybe $100 for the time I used the well to fill it. Was definitely worth it, but o.my because I think it's small. I can't imagine trying that on a larger 1 acre pond or something.
