Pond-Less Cascading Waterfalls
The Extra Large Elite Pondless Waterfall Kit by Blue Thumb let's you experience the beauty of a waterfall without the maintenance of a traditional pond. The maximum stream size with this kit is 18 feet.
A "pondless" or Cascading Waterfall works much like a regular pond. The hole is lined with a flexible liner, then basin matrix boxes are added to create a reservoir. They’re covered with rock and gravel before being filled with water. This helps make it look like a waterfall without a pond, when in fact, the “pond” is there but not visible.

The water circulates via the pump at the bottom of the matrix boxes, inside a Pump Canyon, which pushes water up to a Cascade Waterfall box and into an overflowing waterfall, where it falls back into the reservoir.
Other Pondless Waterfall Kits:
- Elite Medium Falls (15 feet maximum stream)
- Elite Large Cascading Falls (17 feet maximum stream)
Complete Kit Includes: Cascade Spillway Box, Submersible Pump, Pump Canyon® (Vault), Pump Discharge Assembly, Water Matrix, Black PVC Flex Pipe, Installation Kit, Fish-Friendly Rubber Liner, Protective Underliner, Pond Cleaner & Muck Buster Tablets
Build Your Own Garden Retreat
The strong ambient sounds of the Extra Large Cascading Falls Pond-Less Waterfall promote relaxation and help mask unwanted noise. Ideal for both residential and commercial use.
The Design & Engineer Team has compiled an abundance of user-friendly manuals and videos to help with your installation process. See "Resources & Manuals" further below the description for the complete library.
Rocks & Gravel
While not included with this kit, they are necessary to protect your liner from harmful UV rays and animal damage. Plus, they provide surface area for beneficial bacteria to colonize on while creating a beautifully natural look.
