How to Build Outdoor Waterfalls Inexpensively Using Rocks
Introduction
Building an outdoor waterfall can add a touch of tranquility and beauty to your backyard. While traditional waterfalls can be expensive and complex to construct, there is an easy and affordable way to create a stunning waterfall using natural rocks. This guide will provide step-by-step instructions on how to build an inexpensive outdoor rock waterfall.
Materials
- Rocks of various sizes and shapes
- Submersible pump
- Tubing to connect pump to waterfall
- Large plastic flower pot or similar container
- Rigid pond liner
- Sand
- 1 black plastic liner, 4 x 3 feet
Tools
- Carpenter’s level
- Shovel
- Garden hose
Step 1: Dig the Pond
- Determine the desired size and shape of your waterfall pond.
- Excavate a hole in the ground to fit the pond liner.
- Place the pond liner in the hole and adjust it until it is level.
- Fill the bottom of the hole with sand to create a stable base for the liner.
Step 2: Build the Waterfall Structure
- Select flat rocks with sharp edges to act as spillway rocks.
- Lay the spillway rocks on top of each other, creating a cascading effect.
- Use smaller rocks to fill in the gaps between the spillway rocks.
- Elevate the back of the spillway rocks using shims to create a steeper water flow.
Step 3: Install the Tubing and Flower Pot
- Invert the flower pot and thread the tubing through the hole in its bottom.
- Place the flower pot in the center of the waterfall structure, about 8 inches back from the edge of the pond.
- Lay rocks around the flower pot to create four mini-rock walls.
- Lay a long, flat rock across the front of the rock walls to form an overhang for the spillway rocks.
Step 4: Position the Spillway Rocks
- Place the first spillway rock on the overhang, jutting it out over the pond.
- Elevate the back of the rock using shims.
- Position the second spillway rock on top of the first, overlapping it like shingles on a roof.
- Adjust the tubing to form a spout at the end of the second spillway rock.
Step 5: Fill the Pond
- Fill the pond with water and plug in the pump.
- Adjust the position of the waterfall and tubing as needed to minimize water loss from splashing.
Tips for Creating a Realistic Waterfall
- Use rocks of varying sizes and textures to add visual interest.
- Elevate the spillway rocks at different levels to create multiple waterfalls.
- Hide the tubing and flower pot with capstones or surrounding rocks.
- Experiment with different rock arrangements to find the most visually appealing design.
Considerations for Water Conservation
- Position the waterfall so that the water falls as close to the middle of the pond as possible.
- Use a plastic liner or black plastic to cover the area behind the waterfall, preventing water from splashing out.
- Turn off the pump when not in use to conserve electricity and reduce water loss.
Safety Precautions
- Always follow home safety tips when working with electricity and water.
- Ensure that the waterfall is stable and secure before using it.
- Keep children and pets away from the waterfall area when the pump is running.
Conclusion
Building an outdoor rock waterfall can be a rewarding and cost-effective way to enhance your backyard. By following these step-by-step instructions, you can create a stunning waterfall that will provide years of enjoyment and relaxation.
