Waterfall spillway boxes are intended to create a continuous sheet of flowing water that you can direct into your constructed waterfall or stream. These units are designed to be compact, heavy duty and easy to install and disguise. These units are not designed to provide a significant source of biological filtration. Thus, these systems are intended for installation in pond-less systems or as an additional waterfall or stream on a pond with an accompanying biological filter.
We carry spillway boxes from Atlantic™ and PondBuilder™. Sizes range from 10" up to 48" waterfall width.
