No filter is needed in a pondless waterfall? That is correct - a properly designed pondless waterfall needs no filter. It also does not need a centipede module, snorkel vault, or pump housing. The liner industry added all of these unnecessary contraptions to their kits to drive up their profit margins.

I have built hundreds of pondless waterfalls over the years, starting with my first one in 1984 in Fallbrook, California. So, regarding this subject, "A man with experience is not at the mercy of a man with an argument."

1. Value: Pondless waterfalls constructed with a liner cannot be warranted against holes caused by mice, rats, ground squirrels, gophers, chipmunks, tree roots, sharp objects, etc. However, pondless waterfalls that are constructed with concrete and rebar can be warranted for life. Because of this fact, a professionally constructed pondless waterfall will actually add equity to a home. We have compared the cost of materials and labor (hiring a concrete contractor and rebar fabricator) of both methods of construction and discovered that concrete and rebar pondless waterfalls cost the same or less than liner kits cost, uninstalled still in the box)!

2. Filter: Advocates of pondless waterfalls require you to install a "bio-falls" at the top of the falls for a filter. This is a waste of the customer's money because it is not needed. Note: this plastic molded box is cheap to produce and returns exorbitant profits, plus it tacks on additional maintenance costs to the client, requiring periodic cleaning.

3. Pump: For several years the promoters of pondless waterfall liners recommended placing a sump pump in the bottom of the collection basin, and then fill it with gravel. I talked to a woman recently who said, when she turned on the sump pump, before the pumped water would return to the basin, the pump was sucking air (the basin was empty). She did not know where the pump was and the installer would not return her calls. A friend of hers found the pump at the bottom of the basin buried in gravel. And, the pump was all plugged up with debris. There is no telling how many thousands of pondless waterfall customers have this very same problem.

4. Needless extras: The pondless waterfall liner guys came up with the brilliant idea of producing a pump chamber with holes in the bottom, or a centipede or snorkel vault. These are all fancy terms for worthless devices for which they can charge more money. All these contraptions do is keep the gravel away from the pump.

5. Correcting two major design flaws: Our pondless waterfalls are designed with a catch basin. It not only does not contain any gravel at all, but it does not utilize an inefficient, high-maintenance, energy-sucking sump pump that only has a one or two-year warranty. Our pondless waterfall basins (constructed of concrete) contain two 8" anti-vortex suction drains, which feed an above-ground, high-efficiency centrifugal pump which is warranted for three years. The pump uses up to 60 percent less energy, is easy to hide, silent and maintenance free. It utilizes a leaf basket with a "twist and lift" cover for removing debris.

The basin is covered with five or six galvanized grates that are covered with rocks to hide it. The grating holes only allow debris small enough to be drawn through openings in the suction drains where it can be collected in the pump basket for easy removal, thus keeping the basin free from collecting debris. There is no need to ever get into the basin. There is a fail-safe Aquafill water leveler to keep the basin full so you never need to worry about it running dry and burning up the pump. Not to mention that the total volume of the basin is available for water, unlike the liner pondless waterfall that wastes 80 percent of its capacity with gravel. Over several months the gravel plugs up with rotting debris, creating a putrid, slimy, filthy job for the pondless waterfall owner.

6. Last, but by no means least: The reason concrete pondless waterfalls do not need filters is because, unlike the water that slowly moves through the gravel in the basin of a liner pondless waterfall (where the water becomes stagnant from its inability to move freely), concrete pondless waterfalls have an open chamber in the basin, allowing the rapid and free flow of water. This rapid circulation assures that mosquito larvae cannot survive. Nor can algae survive since the basin is covered. This keeps out the sunlight, cools off the water and keeps it clear.

Since a pondless waterfall does not have a pond, you are not dealing with fish food, fish waste, and large quantities of decaying debris. Consequently, there is no need for a filter in a properly designed concrete pondless waterfall. Hundreds of pondless waterfalls since 1984 will attest to that fact.

An ounce of prevention is worth a pond cure. DH

Concrete Desert $9.99 Having recently lost his job as a history professor, David Mapstone returns to his boyhood home of Phoenix, Arizona, to find the city dramatically changed. It's now a haven for wealthy retirees and a seasonal retreat for West Coast ''sophisticates.'' But pockets of his earlier life - some welcome, some not - remain. Mapstone eagerly accepts a temporary job from his old friend and Maricopa County Chief Deputy Mike Peralta: Look into still-open cases and see if he can close any. He is beginning to settle into his new job when his college sweetheart appears at his door one evening. True to his memory of her, she is there because she wants something. Her sister is missing and she wants Mapstone to look for her. Mapstone's search for the missing woman is quickly resolved when her body is discovered in the desert, but he is stunned to find the dead sister in circumstances identical to a sensational 40-year-old unsolved murder. Mapstone's dogged investigation of both murders bridges the chasm of clashing cultures, meshing his own long-ago memories with the tangled doings of newcomers and their acolytes, young women eager to share the lifestyle of tainted wealth, drugs, and careless violence. Jon Talton is a fourth-generation Arizonan who grew up in the same Phoenix neighborhood David Mapstone calls home. Concrete Desert is first in the Mapstone series, followed by Camelback Falls, Dry Heat, Arizona Dreams and Cactus Heart. www.jontalton.com

Production Methods and Workability of Concrete $330 Practical production of ordinary and special, high performance concretes and their behaviour and properties when fresh are the main themes of this book. It derives from the International RILEM Conference held in Paisley, Scotland in June 1996, and represents the culmination of the work of two RILEM Technical Committees (145 WSM Workability of Special Mixes, and 150 ECM Efficiency of Concrete Mixers). Very significant advances have been made recently in the development of concrete with outstanding properties. Such advances in research must be matched by progress in the technology of concrete production. This book focuses on production methods and on workability and handling, two fundamental and closely linked stages of the concrete construction process. It has a strongly practical emphasis, with many contributions showing how to build effectively using the many high performance concretes which have progressed from research into construction in recent years. The main themes covered are: production mixers and mixing processes; production methods; sprayed and very dry precasting mixes; fibre reinforced concrete; flowing and superfluid mixes; rheology; test methods; mix design and models; special cements and concretes

Waste Materials Used in Concrete Manufacturing $180 The environmental aspects involved in the production and use of cement, concrete and other building materials are of growing importance. CO2 emissions are 0.8-1.3 ton/ton of cement production in dry process. SO2 emission is also very high, but is dependent upon the type of fuel used. Energy consumption is also very high at 100-150 KWT/ton of cement produced. It is costly to erect new cement plants. Substitution of waste materials will conserve dwindling resources, and will avoid the environmental and ecological damages caused by quarrying and exploitation of the raw materials for making cement. To some extent, it will help to solve the problem otherwise encountered in disposing of the wastes. Partial replacement of clinker or portland cement by slag, fly ash, silica fume and natural rock minerals illustrates these aspects. Partial replacement by natural materials that require little or no processing, such as pozzolans, calcined clays, etc., saves energy and decreases emission of gases. The output of waste materials suitable as cement replacement (slags, fly ashes, silica fumes, rice husk ash, etc.) is more than double that of cement production. These waste materials can partly be used, or processed, to produce materials suitable as aggregates or fillers in concrete. These can also be used as clinker raw materials, or processed into cementing systems. New grinding and mixing technology will make the use of these secondary materials simpler. Developments in chemical admixtures: superplasticizers, air entraining agents, etc., help in controlling production techniques and, in achieving the desired properties in concrete. Use of waste products is not only a partial solution to environmental and ecological problems; it significantly improves the microstructure, and consequently the durability properties of concrete, which are difficult to achieve by the use of pure portland cement. The aim is not only to make the cements and concrete less expensive, but to provide a blend of tailored properties of waste materials and portland cements suitable for specified purpose. This requires a better understanding of chemistry, and materials science. There is an increasing demand for better understanding of material properties, as well as better control of the microstructure developing in the construction material, to increase durability. The combination of different binders and modifiers to produce cheaper and more durable building materials will solve to some extent the ecological and environmental problems.
