A Pondless® Waterfall is simply a re-circulating waterfall or stream without the presence of a pond. Aquascape Pondless Waterfalls work by pumping water contained in a large, in-ground reservoir up through the Waterfall Spillway, allowing the water to flow back down into the reservoir. This simple recirculation system requires very little maintenance, is easy to install, and is ideal for families with young children or pets that love to play in the water. Selected waterfall kit components work well together to complement and enhance your existing landscape. In just one day you can enjoy the soothing sights and sounds that a waterfall adds to your yard.
