The Aquascape Waterfall Spillway is a cost-effective way to create the starting point of a beautiful waterfall or stream by providing smooth, consistent, leak –free water flow. The Waterfall Spillway is a versatile tool that can be used in a wide variety of water feature applications. As the incoming water rushes in, the water is diffused by strategically positioned internal barriers, creating smooth flow of water. Able to handle flow rates up to 7,500 gallons per hour, the wide 22-inch spillway provides an ideal solution for Pondless Waterfall systems where more expensive biological filters are not necessary. The Aquascape Waterfall Spillway can also be installed as an additional waterfall or stream onto a new or existing pond.
