Aerobic Septic SystemMost septic systems are conventional gravity-fed systems that rely on anaerobic bacteria to break down solid wastes. Sometimes, there are very good reasons to install an aerobic septic system instead. Like all things, there are distinct advantages and disadvantages to having an aerobic septic system. Often, aerobic septic systems are installed because a traditional septic system has failed. An aerobic septic system may also be used if there isn’t enough room to install a traditional septic system.

Aerobic septic systems are different because they introduce oxygen throughout the sewage waste that enters the system. The introduction of oxygen encourages the growth of a totally different type of bacteria than you will find in a conventional system. Unlike anaerobic bacteria, aerobic bacteria need oxygen to thrive.

Here are some of the advantages of having an aerobic septic system:

  • Aerobic bacteria break down waste solids faster than their anaerobic counterparts.
  • The treated water that flows out of an aerobic septic system is cleaner, making an aerobic system a good choice if your property has a higher water table or other environmental challenges.
  • You can build a smaller drain field for this type of system, reducing the total amount of space required for a successful system.

You may be thinking that those are some good advantages and wondering why aerobic septic systems are so rare. There are disadvantages to this type of system as well:

  • Aerobic septic systems are not allowed in all areas, so you will need to ask us if you can install one where you live.
  • These systems are more expensive for several reasons. The initial installation cost is higher. Because the system uses an electric pump to introduce oxygen to the system, there will be ongoing electrical costs. Maintenance costs also tend to be higher because of the increased complication of the system.
