Here’s how it works:
A Retaining Wall Waterfall works much like a pond-less waterfall. The Formal Falls molded Basin is placed on a suitable base with the pump protected inside the basin. Wall block or other suitable material is stacked all around the molded basin. The Formal Falls spillway rests inside the wall block and is covered. The pump inside the basin pumps the water via tubing to the Formal Falls where the water returns via a waterfall into the basin. An LED light strip, located inside the Formal Falls unit, illuminates the waterfall for a spectacular night display.
