Adding a waterfall to your outdoor pond will create a new dimension and building a waterfall is easier than you think.
The overall design of the waterfall should compliment the excisting pond:
As with any garden project, when adding a waterfall to your garden pond
, you must first consider the overall design of the pond and create a plan. It is important to make sure that the scale of your construction fits in with the surrounding features and does not spoil the balance of your overall garden design. The biggest mistake that people make when planning a pond waterfall is to create one too large. For a pond measuring 12 ft x 14 ft you should think in terms of a fall of 18-24 inches. The width of the waterfall should be in proportion to the size of your pond.
Choose the right type of construction:
There are two basic types of construction. A rubber liner
with rocks formed into the shape of the fall or a purchased fiberglass unit
In addition you will need a pump to transport the water from the pond to the top of the falls. The size of pump that you will need depends on the height and width of the waterfall and also the length of pipe from the pump to the top of the fall. Your local building supply center will assist in making the right choice.
Maintain a healthy pond environment usually involves installing a biological filter. Again your dealer will be able to advise you as to the correct type and size. The filter should be placed at the top of the waterfall so that the water is cleaned before running out on to the waterfallfall.
It is helpful if you observe a natural waterfall to give you some ideas as to how the rocks can be placed for the best effect.
If your site is level and the soil from excavation of your pond is nearby this can be used as the mound on which to place the waterfall. If you are using a liner you first dig out the channel and then fit the liner. Next place the rocks so that the water can flow over them. Once you are satisfied with the arrangement, use black waterfall foam to seal the rocks to ensure that the water flows over and around them and not underneath.
If you have chosen to use a fibreglass preformed model, you will avoid the problem of placing the rocks and will just have to dig out sufficient soil to allow you to fit the unit.
To complete the installation fit the pump, filter and hose and connect to the electricity supply. Providing all is working to your satisfaction, now is the time to relax and enjoy your handiwork.
