How deep can the AES and Enviro-Septic® Systems be buried?
Usually the limiting factor on how deep an AES or Enviro-Septic® System can be buried is the depth to the seasonal high water table or some other restrictive feature. If this is not something that poses a problem for you, then the system should not be buried more than 10 ft. deep. It is required that any system with more than 18″ of cover be vented.
