Waterfalls in ponds are attractive to us and the birds, plus you can enjoy the relaxing flow of the water.
To construct a waterfall, it is necessary to make a raised area from which the waterfall can flow downwards. To get a base, you can use the soil previously excavated to create the hole for the pond. It is also necessary to fit a pump, and these come in various sizes. A good retailer will advise on the size of the pump needed for your pond, and an electrician is required to undertake the electrical work safely.
There are pre formed water fall kits which make construction easier. There are all different types and shapes designed to represent different construction materials. The image left is a slate and is a preformed waterfall, which comprised three separate pieces placed together to form the waterfall. Preformed waterfalls are quite heavy, and the key is to ensure the waterfall is bedded in and level. The best way to get the waterfall level is by using sand to pack the sides and underneath, which allows fine adjustments and a spirit level to check. It takes time to level of the sides of the waterfall to make the pre formed kit sit comfortably. Pre formed are good in that they create an instant water fall all in one go, however they may look less natural than a waterfall formed out of original materials.
Alternatively, you can dig out the waterfall shape as part of the overall pond construction and build it yourself using Butyl liner, rocks and slabs, as in the image right. This way you can make a waterfall out of stone local to your area so it looks natural and to the size and shape you design. In both instances, place the pipe leading to the pump first and build the water fall around it.
