Enviro-Septic® is a patented, multi-stage effluent treatment system for residential and commercial use. It is a product designed, tested, manufactured, and distributed by Presby Environmental, Inc., of Whitefield, New Hampshire.
How it works
Here are the nine stages in the
effluent treatment process as diagramed above.
Warm effluent enters the pipe and is cooled to ground temperature.
Stage 2:
Suspended solids separate from the cooled liquid effluent.
Stage 3:
Skimmers further capture grease and suspended solids from the exiting effluent.
Stage 4:
Pipe ridges allow the effluent to flow uninterrupted around the circumference of the pipe and aid in cooling.
Stage 5:
A mat of random, coarse fibers separates more suspended solids from the effluent.
Stage 6:
Effluent passes into the geo-textile fabric and grows a protected bacterial surface.
Stage 7:
Sand wicks liquid from the geo-textile fabric and enables air to transfer to the
bacterial surface.
Stage 8:
The fabric and fibers provide a large bacterial surface to break down solids.
Stage 9:
An ample air supply and fluctuating liquid levels increase bacterial efficiency.
Pipe components
A corrugated, perforated, high-density plastic pipe with a series of unique ridges on the peak of each corrugation and skimmers protruding into the pipe's interior.
A mat of randomly oriented, coarse plastic fibers surrounding the pipe.
A special, non-woven, geo-textile plastic fabric surrounding a mat of fibers and stitched in place.
System components
Each unit of Enviro-Septic® pipe is 10 feet long, has an outside diameter of 12 inches, and is clearly marked with the product's name.
Snap-lock couplings, offset adapters, and end caps are used for the system assembly.
Readily available and easily worked gravelly coarse sand or an ASTM standard C-33 for concrete sand, is used to surround the pipe to a minimum distance of six inches.
