Five Differences Between Aerobic and Anaerobic Systems

If you are looking into septic tank installation in Canyon Lake, TX, it is good to know your options. New property owners, especially those who are accustomed to living on the grid, often believe any septic system will do. However, there are traits unique to aerobic septic systems that may make this a better choice for your property. Here are five differences between aerobic and anaerobic septic systems:

  • Presence of oxygen: The primary difference between the two systems is how they use (or do not use) oxygen. Anaerobic systems operate underground with either low or no levels of oxygen, and any bacteria colonies must have the capability of surviving without it. Aerobic tanks are also kept underground, but an aerator ensures a constant supply of oxygen. This allows bacteria that require oxygen to survive and thrive in these systems.
  • Bacteria types: As mentioned above, some bacteria strains can survive without oxygen, while others cannot. However, those that thrive on oxygen work better in septic systems. Aerobic bacteria are less vulnerable to household chemicals and break down human waste more efficiently than anaerobic bacteria. But you have to be careful with what you flush if you choose an aerobic septic system. Aerobic bacteria have less ability to break down inorganic solids, and that can lead to clogs. If you believe that will be an issue, choose an anaerobic system knowing there will be some efficiency costs.
  • Drain field size: The drain field is a significant part of any septic system. It receives partially-treated water for further treatment and distribution through the soil. Aerobic bacteria breaks down more organic waste, so aerobic septic systems do not require a large drain field. This can be important if your property is smaller or is not optimal for a drain field.
  • Expense: Aerobic systems are more expensive to maintain than anaerobic systems. They require additional mechanical parts, and this means more repairs and maintenance. You will notice your electricity bills increase to run that equipment. There are benefits, like a cleaner, more efficient septic system.
  • Alarm: Aerobic systems contain an alarm to alert homeowners to any issues. This will allow you to address the problem that caused the system to enter into an alarm. Undetected septic problems escalate quickly, and an alarm is often considered vital. Anaerobic systems do not contain an alarm, so you will not know anything is wrong until it is bad (and the results of your septic tank rise to the surface). Since this allows you to address problems early and avoid massive repair or replacement costs, many customers consider the maintenance costs of aerobic systems well worth it.
