A more energy efficient, but difficult to execute on option would be to adapt the process so first some space is created you could then fill with water, turning the entire thing into a two-step process. Of course, if your only goal is to have a way to dump water somewhere it won't bother you, sending it to some other plane that is not full of water, like the elemental plane of fire, might be easier.
edit: it should be noted that if you sync up your taking and returning rings to operate at the same time from the same spot that would work, but the end result is no water created, and you'd pretty quickly start getting the same bit of water cycling between the two rings. Still, there might be something you could do with that process.
