Safety...Because there is no pool of water, an Aquascape Pondless® Waterfall is a great option if you are concerned about safety issues associated with a traditional pond.
Cost...Cost can be a big factor when considering the type of water garden you want to build. In most cases, the price of an Aquascape Pondless® Waterfall will be less than a pond, because there is less labor involved, as well as less rock and materials. Operating costs are also less. Because you are not dealing with an established ecosystem, it is not necessary to run the pump 24/7.
Space...The small size of the Aquascape Pondless® Waterfall means you can build and enjoy a beautiful waterfall anywhere in you yard.
