Wall fountains work by combining a water pump and a water reservoir. The pump circulates water from the reservoir to the fountainhead, releasing it and cascading it down the wall. The water then flows back into the reservoir, allowing the cycle to start again. Rather, wall fountains are quite compact, electricity-powered contraptions that fit right into the decor of a home or office. Unlike fountains that shoot or spray water, a wall fountain sends water in a cascade down a flat front surface.
