Building a waterfall garden pond can add beauty to your outdoor space and give it more curb appeal, adding to the value of your home. It's a challenging project but if you take it one step at a time, soon you can have a beautiful addition to your backyard or garden.
Step 1 - Plan Your Pond
Where you put a waterfall garden pond depends mostly on how you want your yard to look and whether or not the ground is level enough or can be leveled enough for a pond. Choose the size and shape of the pond liner you want and dig the hole for the liner. With many home improvement projects, starting small is a good idea but with a garden pond that you make with a pre-formed liner, you can't expand it to a larger pond later. Choose the size you want now—a larger pond is no more difficult to install than a small one, it only requires more digging. Dig a section outside of the actual pond-form area to leave room for your waterfall.
Step 2 - Install the Pond Liner
If you're using a shaped, pre-formed pond liner then just smooth the bottom of the hole and install. If you're using a soft liner, spread sand in the bottom and smooth it out, then install the liner, flattening it out as much as you can. Secure the edge of the liner with rocks, pavers or treated lumber. Put the pond filter in the bottom and attach the tube between it and the pump, then attach the water tube to the pump. Arrange decorative rocks to camouflage the pump while leaving it easy to get to.
Step 3 - Install the Waterfall Form
If you've purchased a pre-formed fiberglass waterfall form, which is an easy way to get a great looking waterfall, then make sure the area you dug out next to the pond is large enough, then put the form in place. Run the hose from the pump to the top or side of the form, disguising it with plants or landscaping rocks. If you want to make the waterfall yourself, then you'll need to spread some sand over the area and use another flexible liner. Arrange flat rocks the way you want, so that you can run water from the top and it will cascade down in your waterfall garden pond.
Step 4 - Fill the Pond
Put any pond plants or decorations into the pond now while it's empty, placing them on rocks or risers so that they'll be above the water level when the pond is full. Run a hose from an outside spigot and fill your pond. When you run the pump, it will suck water from the pond and send it over the cascading waterfall you've built back into the pond. Place plants away from the waterfall to keep them from being damaged.
Step 5 - Start the Pump
Start the pump and adjust it to the pumping speed and volume you want so that you have a cascading waterfall garden pond.
