A properly designed and constructed septic system is the most efficient method for disposing of household sewage. A typical septic system consists of a septic tank and a leaching field. Generally, the septic tank is a two chamber concrete, 800 - 1,000 gallon airtight tank. The leaching bed is comprised of rows of perforated 3 inch pipe set 5 ft. apart on a 6 inch stone layer. The bottom of the trench must be at least 1.5 ft. above the groundwater table and 3 ft. above bedrock or impermeable soil.

In septic tanks, waste matter is decomposed through bacterial action. Inside the septic tank, you would find three layers. The top layer is the "Scum” layer, where organic material floats to the surface. Bacteria in the septic tank biologically converts this material to a liquid. The middle layer is the “Effluent” layer where mostly clear water will be found. This clear water is the only layer that should enter your absorption area. The bottom layer is the “Sludge” layer. This layer is where the inorganic or inert solid materials and the by-products of bacterial digestion accumulate.

In a properly functioning septic tank, household waste is broken down, liquefied, and deodorized through a natural (biological) process. Overuse of disinfectants, bleaches, detergents, and extreme hot or cold conditions can upset this process (reduce microbial populations) and cause the system to become inoperative.


Using ESTT is simple... Just drop a convenient water soluble pouch into your toilet bowl and flush. ESTT is safe to use as directed. It is completely natural, contains no corrosive chemicals and is hazard free. It will not damage metal, ceramic, or the plastic parts of the drainage system.
