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.
