I pay $5 a horse for 4 horses a month on 5 acres. There is water if I need it but it opens into my pasture so I haven't had to make use of it. It's on its own meter with neighbor's 3 other pastures so bill would be divided and averaged then added to our cost. She charges $100 per 5acres for each of the other three with water included and a 3 sided shelter. No more than 2 per pasture. If she feeds she adds another $50 per month.
