If the tank is properly sized for garbage disposal use and equipped with baffles, the AES or Enviro-Septic® System’s size does not need to be adjusted due to the use of a garbage disposal.
The use of a garbage disposal adds considerably more solids to a septic system than are usually present. This typically requires a larger septic tank (or a multiple tank design) and more frequent pumping. Please inform your system designer of your intention to install a garbage disposal for this reason.
Often, garbage disposals are installed at a later date after the System has been installed. If this is the case we recommend that the AES or Enviro-Septic® treatment bed size is increased by 10%.
