Aerobic Septic SystemThere are many reasons to consider an aerobic septic system. These systems can exist as new installations or as retrofits to an existing system.

An aerobic septic system or aerobic treatment system works by creating conditions more favorable to aerobic bacteria. These bacteria are usually faster and more effective at breaking down waste than the anaerobic bacteria common to most septic systems. Because of this, an aerobic septic system will produce an effluent that is generally of higher quality and contains fewer dangerous bacteria or particulate solids. The effluent can be disposed of in a safer manner and generally requires fewer setbacks or less distance to obstacles or rock layers. This effluent can sometimes be retrofitted into an existing system with a compromised or biomat-growing drain field. Doing so can restore better function to a drain field compromised by bacterial and biomat overgrowth.

There are two main types of aerobic septic systems. The first uses a porous medium to provide a growth support for the biomat. The second uses an air pump to continuously move and aerate the wastewater, increasing the oxygen diffused in the wastewater and relying on bacteria already present to ramp up their digestion of the waste involved. While the precise designs may vary from installation to installation, the general principles work on a new system or on the retrofit of an old or even failing anaerobic septic systems.
