  • Permitted to be smaller and closer to restrictive features than conventional systems
  • Require no reserve area in most cases
  • Can be installed in soils which are not appropriate for other onsite systems

AES and Enviro-Septic® have an extremely low failure rate, and the unique ability to be “rejuvenated” if the System is abused. It has become the “system of choice” in our home state of New Hampshire–accounting for 90-95% of system installations statewide in recent years. It has been in use in New England since 1995.

AES and Enviro-Septic® pipe is a proprietary device covered by numerous US Patents and manufactured exclusively by Presby Environmental/Presby Plastics.
