I've done the tree watering system for several years now, mine's always been a siphon solution. A good friend created a system that was managed via an electric pump, and sadly he came home to a very wet carpet one day. So if you pursue that, make sure your system handles errors well.
As for a sensor: A two or 3 point continuity circuit is definitely the easiest - I highly recommend it.
