What Are Common Aerobic Septic System Problems And Their Solutions

Updated: Dec 16, 2024

Aerobic systems are popular for wastewater treatment in residential and commercial settings. They use oxygen to break down organic matter, making them efficient and environmentally friendly. 


However, as with any system, issues can arise over time.


In this article, we discuss some common problems that can occur in aerobic systems and their solutions.


What Is An Aerobic Septic System? 


What Is An Aerobic Septic System

Before we explore the problems and solutions, let's first understand what an aerobic septic system is. An aerobic system is a wastewater treatment system that uses oxygen to break down organic matter. 


It consists of a tank where the wastewater is initially collected, followed by a second tank where bacteria use oxygen to digest the waste. This process produces less sludge and has a higher treatment efficiency than traditional anaerobic systems.


Common Aerobic Septic System Problems & Solutions


Common Aerobic System Problems & Solutions

Clogging 


One of the most common problems with aerobic septic systems is clogging. This can occur due to a buildup of solid waste in the system or if the pump gets clogged with debris. 


Clogging can lead to backups and overflows, causing unpleasant smells and potential health hazards.


Solution: To prevent clogs, it's essential to have your system regularly inspected and pumped every 2-3 years. Also, avoid flushing non-biodegradable items like paper towels, wipes, or feminine hygiene products down the toilet.


Failure Of The Air Compressor


The air compressor is a crucial component of an aerobic system as it supplies oxygen to the bacteria for waste digestion. If it fails, the bacteria will die off, and the system will no longer function effectively.


Solution: Regular air compressor maintenance is necessary to ensure its proper functioning. If you notice any strange noises or decreased airflow, it's essential to have a professional inspect and repair the compressor immediately.


Tree Roots Growth 


Tree roots can grow into aerobic septic systems, causing damage to pipes and even clogging them completely. This issue is more common in older clay or cast iron pipe systems. 


Tree roots can cause damage to your septic system if they grow too close to your drain field or pipes, resulting in blockage or clogging.


Solution: Plant trees away from your septic system and regularly check for any root growth. If you notice roots getting too close, have them removed by a professional landscaper.


The Spray Head Malfunctions 


You might have noticed the aerobic septic system sprinklers are not coming on. It might be due to the system’s spray head not working. 


If the spray head on your septic system is not working correctly, it can lead to clogs and backups. It is also one of the common aerobic septic system problems. 


Solution: Check the spray head regularly for any clogs or debris and clean it if necessary. If the problem persists, contact a professional to repair or replace the spray head.


Submersible Pump Issues


If your septic system has a submersible pump, it is essential to monitor its performance. A malfunctioning pump can lead to backups and overflows. It is mainly caused due to bad wiring and bad float. 


Solution: Have the pump inspected regularly and replace it if necessary. A backup pump should also be installed in case of emergencies.


Power Outages 


Aerobic septic systems use electricity to pump and aerate waste within the tank. The system can back up during power outages, leading to potential backups and malfunctions.


Solution: Installing a backup generator can help prevent issues during power outages. Conserving water usage during these times is essential to avoid overloading the system.


Clogged Chlorinator 


The aerobic septic system is built to manage water wastage by systematically killing the bacteria and then moving the anaerobically treated water to the home sprinkler for reuse. 


Before it happens, the water is also chlorinated to make it clean and germ-free. This chlorinator works for a year or more but could clog due to debris buildup. An aerobic septic system alarm going off might indicate the clogged-up chlorinator.


Solution: Regularly check and clean the chlorinator to prevent clogs. If you notice any damage, contact a professional to repair or replace it. This will ensure that your septic system consistently provides safe and healthy wastewater treatment.


Aerobic System OverFlowing


Aerobic system overflowing is another issue with such systems. It happens if debris or sludge builds up, leading to blocked sewer pipelines or drainfields. It can also result in poor maintenance and excessive usage of water. 


Solution: Regularly monitor your water usage and avoid excessive use. Also, regularly maintain your aerobic system by scheduling regular inspections and pumping as needed. If the problem persists, contact a professional for further assistance.


How Does The Aerobic System Work?


How Does The Aerobic System Work

An aerobic septic system is a system for extending wastewater treatment through the use of oxygen-enthusiast bacteria in breaking massive underwater waste compared to other traditional septic systems.


It typically has three main components: All these systems include, but are not limited to, a trash tank, a treatment tank, and a disinfection unit. 


Wastewater must first pass through the trash tank, where the most significant drop of sediments settles. The treatment tank provides then air, where other aerobic bacteria would complete waste digestion.


When the water reaches the ground, it must first go through a disinfection chamber that removes all the bacteria. 


How Often Should An Aerobic Septic System Be Pumped?


How Often Should An Aerobic Septic System Be Pumped

An aerobic septic system should be pumped every 3-5 years, depending on your household size and usage.


However, if you notice any signs of a full tank or slow draining, it's best to have it pumped immediately. Regular septic tank pumping will help prevent clogs and maintain the efficiency of your system.


How Long Do Aerobic Septic Systems Last?


How Long Do Aerobic Septic Systems Last

Aerobic septic systems can last up to 20-30 years with proper maintenance and care. However, this lifespan can vary depending on the system's quality, usage habits, and environmental conditions.


Regularly scheduled maintenance is crucial for extending the life of your aerobic septic system. Inspecting and pumping the tank every few years will help prevent significant damage or costly repairs in the long run.


How Do You Reset An Aerobic Septic System?


How Do You Reset An Aerobic Septic System

If you are experiencing issues with your aerobic septic system, such as septic tank foul odors or backups, it may be necessary to reset the system.


Here are the steps to follow for resetting an aerobic septic system:


  • Turn off the power: The first step in resetting an aerobic septic system is to turn off the power supply to the aerator and other system components.


  • Access the control panel: Locate the control panel for your aerobic septic system. This is typically located near your house, above ground level.


  • Reset the alarm: If an alarm has been triggered on your control panel, press the reset button to silence it. This will allow you to reset the system.


  • Check the pump: It is essential to check the pump for any clogs or damage before resetting the system. Clean or replace the pump if necessary.


  • Reset the timer: The timer on your aerobic septic system controls when and how long the system operates, so it may need to reset if there has been a power outage or other issues. Follow the manufacturer's instructions for resetting the timer.


  • Turn on the power supply: Once all components have been checked and reset, turn on the power supply to your aerobic septic system.


  • Monitor for changes: After resetting your aerobic septic system, monitor its operation closely for any changes or irregularities. Contact a professional septic system maintenance service if you notice any issues.
