Orenco Systems, Inc.

Zabel Environmental Productshttp

The most serious problem with septic systems is a failed drainfield: when solids migrate from the tank into the drainfield, with resultant clogging. Two companies, Zabel and Orenco, make plastic filters that intercept solids at the outlet tee where the effluent flows into the drainfield. The filters need to be cleaned every two to three years, but are said to be somewhat self-cleaning if used properly. (The screens provide a surface area for microorganisms to grow, which in turn degrade the harmful particles into basic elements and compounds.) Both types of filters can be retrofitted into an existing septic tank and are especially valuable anywhere (residential or commercial) that wastewater has a high suspended solids content.

G. T. Water Products

This is a brilliant invention for unclogging plugged drains without using caustic chemicals such as Drano or calling a plumber. It comes in various sizes for different size pipes and consists of a rubber bellows-type device that you connect to a garden hose. You insert it into the drain, turn on the hose, and the bellows expands, sealing off the pipe while emitting powerful, drain-clearing pulses of water.


It’s inspiring that ecological awareness in the ’60s and ’70s caused toilets to be redesigned so that the typical 5 to 6 gallon flush was replaced by the 1.6 gallon flush. Trouble is, however admirable in water conservation, many of the early models didn’t really get the job done, either requiring a plunger, or leaving what Robert Kourik refers to as “skid marks.” Now, there is a new generation of low-flush toilets and some work better than others. One that works extremely well is the Toto 1.60 Gpf/6.0Lpf. In an independent ANSI test of 31 low-flush toilets, Toto scored highest for best performance — higher than more expensive models. Toto, in Morrow, GA, is the world’s largest supplier of toilets.

Septic Protector

Lint from washing machines is the leading source of solids that clog drainfields. Adding to the problem are fibers from synthetic clothing, which get into the drainfield, clog the pores of the soil, and do not break down as do natural fibers like cotton. This is a stainless steel filter for washing machines that keeps lint out of the soil; it’s an excellent idea and a good product. It attaches to the outflow hose of the washing machine. It has a reusable 160-micron filter that you empty every few weeks. It comes with a 90-day, money-back guarantee.


W. F. McCollough

This is a unique, flexible, waterproof 5 inch by 7 inch plastic card with nylon lanyard that contains miscellaneous data on charicteristics of different soils. On one side are samples of six different types of common soil colors; on the other side are pasted-on actual sand grains, from coarse to silt. The sand grains and color chips are permanently fused to the plastic. Although this book does not go into soil analysis, this card can tell you what type of soil you have, and gives you field tests for determining clay consistency and type of sand in the soil.
