SimpleSepticSimple-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.
