Dick, if you can put a breaker box at the pond to split off your 110 service, you can simply rewire the current supply line to 220. It's a very easy job and would probably cost under $200 even if you had to hire a pro. If you do it yourself, be sure to reduce the 220 breaker to 1/2 of the current one.
