build a pond

Definition: A waterfall pondless or "childproof" waterfall is a waterfall that falls into an underground drainage basin or tank instead of a pond. The collected water is returned to the top of the waterfall through a pumping system.

Why Pondless?

In 1984 I built what I called a "child proof" waterfall in reinforced concrete, because building codes state that due to the factor of responsibility, ponds can only be 18 "deep or if they are required to comply with all codes in the same building, and the requirements of a swimming pool (6 foot perimeter fence, special doors, door alarms, etc.). "From this waterfall is in the front yard, could not be more than 18" and if it was, there was no room sufficient for a pond large enough to prevent squeezed by the time the water returns to the lagoon through the waterfall. So I installed a system level electronic water collection basin to ensure water is automatically replenished as needed. My term for this type of water feature is "a test in children ", and makes it safe for children and eliminates the factor of responsibility and passing building codes. Since the advent of the use rubber coating for building waterfalls and ponds in the nineties, this type of cataract has been called a cascade "pondless."

Rubber line ponds and waterfalls are ideal for short term use, however, are susceptible to attack by rats, mice, squirrels, gophers, squirrels, roots of trees, sharp objects, ranging from boulders, heavy etc go into detail about critical defects of the construction of a pond liner article entitled Pondless Waterfalls: Concrete vs. Liners Ezinearticles. This article contains documentation leaves no doubt that the falls are pondless cheaper to build with concrete and steel instead of using an online kit pondless waterfall. Not to mention that it is cheaper to operate and maintain.

The key to making of natural looking waterfall is sure eliminate a lot of dirt, to stop the fall of water in the soil. Many make the mistake of building above the natural level the degree of the original note. The rocks are not natural to stick on the surface of the earth. This is especially if the rocks are the only waterfall visible in the bank, hill or grade where the waterfall. The rocks of the waterfall must give the impression that over the years have washed down the hill or a bank, eroding surface distance original soil and exposure of rocks hidden beneath.


The next step is to apply the 3 / 8 "bars 8-10 inches on center, which cross each other, and hold them together in a network using a cable tie to hold together. Small 2 "x 2" blocks called Dobies are subjected to the network to maintain above the dirt. When the concrete is applied, it should completely surround all reinforcement bars. There can be reinforcing bars touching the ground or rust. And the rust, such as cancer will spread and follow the rebar in the concrete structure. As the rod swells oxidizes, much like you would when it gets moisture in it. The hydrologically swollen rebar causes concrete to crack.


Use flexible PVC pipe, not a rigid pipe, because it is easy to handle in the corners and on uneven ground. But above all, through the use of flex eliminate the need for accessories such as elbows and joints underground, thus eliminating possible future sources of leaks.

You can install the flex in the reinforcing bar or next to it, of course, the waterfall. One of the main failures pondless waterfalls lining is constructed using suction pumps that suck the energy (60% more than the centrifugal pumps). Then fill the tank with gravel pump, reducing the water space available. Consequently, when the waterfall is running, most of the catch basin or tank is emptied of water before that previously pumped water can return to the basin. This makes it necessary to add water to regulate the pump basin or dry and burn.

Construction concrete

In concrete construction, anti-vortex suction drains (like what is used in swimming pools) can be installed in bottom of the basin. galvanized grid can be distributed throughout the basin and the rock placed on top of the screen to hide it.

Now with the empty Cuba and free of gravel to allow enough room for water storage. An out of the lagoon, high performance centrifugal pump can be used to circulate the water. A Unlike the sump pumps that are used in the construction of the line, a centrifugal pump uses 60% less energy, is easy to maintain, has three times the warranty, has four to five times the life expectancy, and there is increasing need for access to the basin or eliminate smelly, dirty gravel to reach the pump.

Concrete Implementation

Most fire engines know how to apply concrete rebar concrete waterfall, and only charge a couple hundred dollars. Llana is easy, anyone can do it because it has to be soft. Just down the rough edges and smooth with a sponge.

The concrete itself only costs $ 100 – $ 125 yards with more pondless waterfalls that requires only 2-3 meters. As for the cost of a single line kit (Not working)! and search the Internet under "vs. concrete pond liners."

Do not waste your money on a temporary solution. Reinforced concrete reality cost less and will last for decades.
