enviro septic systemPresby Environmental Septic System

Enviro-Septic® is an innovative leaching system designed for residential and commercial septic system applications. Enviro-Septic® can be used in a variety of configurations and requires a smaller area in comparison to conventional septic systems.  

These systems are typically less expensive due to the decrease is space needed over a conventional system.  Enviro-Septic® is easily installed on slopes, eliminating the need for “septic mounds.”  The system consists of a series of uniquely designed, perforated corrugated plastic pipes, each surrounded by a layer of random plastic fibers in turn covered by a geo-textile fabric. 

The effluent disposal area is a bed of washed septic sand laid on top of a layer of bank run sand.
