How to Make a Small Homemade Waterfall Project
- 1). Decide how high of a slope you would like for your waterfall and how large of a pool you want at the bottom.
- 2). Dig out the space for the lower pool. For a pool that measures 12 by 14 feet, the fall distance of your waterfall should be approximately 18 to 24 inches. Cover the base of the pool with either sand or a pond liner, and place a layer of small rocks down to improve the visual appeal of the bottom of the pond.
- 3). Use the dirt excavated from the pool to form a small hill. Slope the hill in the angle you desire for your waterfall.
- 4). Place the rocks--with the heaviest at the bottom--along the slope of the hill of dirt. Place them in whatever design appeals to you. Be sure to have some overhang of rocks over the pool, as this creates the fall for the water.
- 5). Connect the pump hose to the pump. Thread the hose up behind the rocks covering your stone cascade; it should reach the top. Use stones to cover the hose in any areas that it's visible, as this gives the waterfall a more natural look.
- 6). Place the pump in the lower pool. Don't allow it to touch the sides or bottom, so the water will flow properly. Connect it to the GFCI receptacle, and ensure it is working by testing it.
- 7). Add water to the pool, then turn the pump on to test the water flow. The pump hose should send water flowing down your homemade stone cascade into the pool.
- 8). Rearrange the rocks to create your desired effect. You can add bushes, plants, flowers or additional stones around your waterfall to beautify the pool edge, and to blend your new addition into the style of your backyard.
