In planning to build outdoor waterfalls, you need to concentrate on two structures: the pool into which the water falls and the cascading structure for the waterfall itself. The latter is often the more difficult to build, but in this article, I show you how to build it in a way that is not only simple but cheap. It involves using rock, which many homeowners have right in their own backyard.
Once these two structures are in place, you’ll use a pump in the pond to keep water recirculating from the pond to the top of your waterfall, whence it can plunge back down to the pond. Outdoor waterfalls come in all shapes and sizes and make for emphatic focal points. When mulling over your design options, the main consideration is how to achieve the necessary height for the waterfall.
Often, a landscape designer exploits a slope on the property, or else (if the whole property is level ground) erects a berm to create such an area behind the pond.
