      I assumed it was like an infinity pool were any water that goes over the edge is caught and drained. In this case, using a pump to either put it back in the water part, or in some kind of holding tank to handle heavy rains and stuff.

        Congratulations on being the smartest person in this thread so far, no one else has apparently ever heard of a pump before
