When the space is tight and you want to build it right, Savio's Compact Waterfall Well is the best solution. The new Compact Waterfall Well gives you even more options for your small and compact pond free features! The Compact Waterfall Well allows you to hold more water in a smaller basin than using rocks alone. Additionally, it provides easy access and protects your water pump. Patented design protects your pump from the crushing forces of rock and water with a structurally tough injection-molded housing. The snap fit enclosure is easy to assemble. Includes base and Savio's signature lid.
