Presby Environmental Inc. (PEI) products

The Advanced Enviro-Septic (AES) Treatment System has been proven to remove up to 99% of wastewater contaminants without using any electricity or replacement media. Advanced Enviro-Septic is patented and patent-pending. AES is the revolutionary wastewater treatment system that combines treatment and dispersal in the same small footprint and for considerably less money.

This revolutionary onsite treatment system removes up to 98% of wastewater contaminants, recycling clean water into the environment and recharging natural water supplies. Enviro-Septic is patented and patent-pending.

Simple-Septic (SS) contains many of the proprietary features of Enviro-Septic (ES) and Advanced Enviro-Septic (AES), giving it superior performance and longevity compared to other single-layered fabric products. Without the added surface area and void space provided by the green fibers, single-layered products cannot develop the self-sustaining ecosystem of ES or AES. SS provides the most economical solution for leach field applications.

The septic tank insert that pre-treats wastewater!. Reduces treatment field size. Lowers the cost of installation. Increases the life span of the treatment field.

OrnaVent™ is our new vent disguise with the purpose of decorating the high or low vent on Advanced Enviro-Septic®, Enviro-Septic®, Simple Septic®, and EnviroFin™ Septic Systems. For more information on the importance of venting on Presby Septic Systems visit the Venting page.

Spec-Check (patent pending), developed by and available exclusively from Presby Environmental, is a portable, hand-operated device used for sorting/grading a sample of aggregate, sand or other particulate material in order to determine whether a sample meets a specification for an intended use. Unlike a lab analysis, the Spec-Check does not need the sample to be oven-dried to remove all its moisture content. The device is small and easy to operate, making onsite examination of materials a quick and cost-effective alternative to expensive and time-consuming sieve analyses by a laboratory.
