In this article, we will explore the most common ATU issues, ranging from reduced aeration and system imbalances to mechanical malfunctions, providing insights into their root causes, as well as the best practices for troubleshooting and maintenance. Along with this, we will emphasize the importance of partnering with an expert service provider like Alternative Septic Management, Inc. to maintain and repair ATUs effectively.


Common ATU Issue #1: Reduced Aeration


Aeration is the key component of aerobic treatment units' wastewater treatment process. Aerobic bacteria rely on an adequate oxygen supply to break down waste materials effectively. Reduced aeration can lead to various problems, including increased odors, decreased wastewater treatment efficiency, and imbalances in the bacterial population. Some common causes of reduced aeration in ATUs include:


- Clogged or Damaged Air Diffusers: Over time, the air diffusers in the aeration chamber can become clogged with debris or suffer wear and tear. Regularly inspecting and cleaning the diffusers will help maintain optimal aeration.


- Malfunctioning Air Pump or Blower: The air pump or blower is responsible for supplying oxygen to the aerobic bacteria. If this component fails or operates inefficiently, it can lead to reduced aeration. Schedule regular checks and maintenance of the air pump or blower to ensure its proper functioning.


- Leaks or Blockages in Aeration Tubing: If the tubing that carries air to the diffusers becomes damaged, kinked, or blocked, it can impede the flow of oxygen. Inspect the tubing regularly and replace or repair it as needed.


Common ATU Issue #2: System Imbalances


ATUs rely on balanced bacterial populations to effectively treat wastewater. When the balance is disrupted, the treatment process's overall efficiency may decline, leading to poor effluent quality and increased odors. Some factors that may contribute to system imbalances include:


- Overuse of Harsh Chemicals: While cleaning agents and other household chemicals may be necessary for daily activities, excessive use of these products can disrupt the balance of bacteria in your ATU. To minimize disturbance to the bacterial populations, consider using septic-safe cleaning products.


- Fluctuations in Wastewater Flow: Abrupt changes in the volume of wastewater entering the system can negatively impact the bacterial balance. Strive to maintain consistent wastewater flows by avoiding the simultaneous use of multiple water-intensive appliances.


- Inadequate Aeration: As mentioned earlier, sufficient aeration is crucial for the health and effectiveness of aerobic bacteria. Ensuring that the aeration system is functioning correctly can help maintain proper bacterial balance.


Common ATU Issue #3: Mechanical Malfunctions


Various mechanical components of ATUs, such as pumps, blowers, and control panels, play crucial roles in the system's overall operation. Malfunctions in these components can lead to ATU issues, system failures, and the need for costly repairs. To prevent mechanical malfunctions, be sure to:


- Regularly Inspect and Maintain Pumps: Pumps are vital for moving wastewater through the different treatment stages. Assess the pumps' performance regularly and replace or repair them as needed.


- Monitor the Control Panel: The control panel serves as the "brain" of the entire system, managing the various components and ensuring proper operation. Regularly check for any warning lights or error messages and consult with a professional technician to address any issues that arise.


- Clean and Maintain Air Blowers: Air blowers are essential for supplying the necessary oxygen to aerobic bacteria in the treatment process. Regular cleaning and maintenance of the blowers can help prevent malfunctions and maintain optimal aeration levels.


Common ATU Issue #4: Sludge and Scum Accumulation


Regular build-up of sludge and scum in the pre-treatment chamber of an ATU is natural but, if left unchecked, can lead to problems such as clogs, backups, and reduced system efficiency. To manage sludge and scum accumulation, consider the following steps:


- Schedule Periodic Pumping: Regular pumping of the sludge and scum from the pre-treatment chamber is essential to prevent system overload and maintain efficient treatment processes.


- Avoid Disposing of Grease and Oil into the System: Grease, oil, and fats can contribute to scum accumulation in the pre-treatment chamber. Prevent pouring these substances down the drain to minimize scum build-up.


- Implement Water Conservation Measures: Reducing the volume of wastewater entering your ATU eases the burden on the treatment processes and helps minimize the accumulation of sludge and scum.

Hydro‑Action Systems for Cleaner Wastewater Treatment

August 6, 2025
Why Environmentally Responsible Systems Matter in Georgia Water Resource Protection In Georgia, protecting natural water resources is critical. Our state depends on groundwater, lakes, rivers, and wetlands for drinking water, recreation, and agriculture. Improperly managed wastewater from septic systems can introduce contaminants such as nitrates, phosphates, and harmful bacteria into the soil and water supply. This not only threatens human health but can also degrade entire ecosystems. At Alternative Septic Management, we believe that responsible wastewater treatment begins with choosing systems that support long-term water quality. Growing Local Regulations Georgia counties are increasingly tightening their environmental standards regarding septic systems. Many areas now require more advanced wastewater treatment solutions, particularly in locations near wetlands, flood zones, or community wells. These changes are driven by the need to control pollution and minimize health risks. Hydro‑Action systems meet or exceed these regulatory expectations. As specialists in advanced septic technologies, we help Georgia homeowners stay compliant by installing systems that align with state and local standards. How Hydro‑Action Systems Support Long-Term Sustainability Aerobic Treatment Reduces Contamination Hydro‑Action systems use aerobic treatment processes that infuse oxygen into wastewater to support aerobic bacteria, which are more efficient than anaerobic organisms in breaking down organic waste. This technology produces effluent that is significantly cleaner than that from traditional septic tanks. The result is wastewater that poses less risk to the surrounding environment and water supply. Cleaner Effluent Helps Preserve Ecosystems When effluent enters the soil at a higher quality, it requires less natural filtration and is less likely to pollute water sources. This is particularly important in Georgia, where many homes are located near lakes, streams, and protected land. Advanced treatment systems help preserve these ecosystems by reducing nutrient loads and limiting bacterial contamination that can harm wildlife and aquatic environments. Smart Habits for Efficient and Safe Septic System Operation Use Septic-Safe Cleaning Products Many household cleaners contain harsh chemicals that can damage the delicate bacterial balance inside your septic system. These include bleach, ammonia, and chemical drain cleaners. When introduced into a Hydro‑Action aerobic system, these substances can kill off the beneficial bacteria that are critical to waste breakdown. We advise using biodegradable and septic-safe products to help maintain bacterial health and prevent system malfunctions. Avoid Flushing or Draining Harmful Materials Proper septic care also means being mindful of what goes down your drains. Items like grease, oils, disposable wipes, feminine hygiene products, coffee grounds, and prescription medications can create clogs, kill bacteria, or damage mechanical components. Even in advanced systems like Hydro‑Action systems, introducing the wrong materials can lead to costly repairs and premature system failure. Maintain Bacterial Balance Through Scheduled Maintenance Routine service is not optional for aerobic treatment systems; it’s essential. Hydro‑Action systems rely on an optimal environment within the treatment chamber to keep bacteria levels healthy and effective. Regular maintenance includes checking the aerator, cleaning filters, and making sure the system isn’t overloaded. At Alternative Septic Management, we offer recurring service plans that help homeowners stay on schedule and avoid performance issues.

How Routine Hydro‑Action Maintenance Prevents Costly Repairs

July 20, 2025
At Alternative Septic Management, we specialize in maintaining Hydro‑Action aerobic treatment systems for homeowners throughout Georgia. These advanced septic systems provide excellent wastewater treatment, but only when they’re properly maintained. Ignoring scheduled maintenance can lead to serious and expensive issues. In this blog post, we’ll walk through how routine care protects your investment and helps prevent costly repairs. The Role of Hydro‑Action Systems in Georgia Homes Hydro‑Action systems are aerobic treatment units (ATUs), which treat wastewater using oxygen and beneficial bacteria. Why Aerobic Systems Need Regular Maintenance Unlike conventional anaerobic systems, Hydro‑Action units rely on a delicate balance of mechanical components and microbial processes. Oxygen is pumped into the system to support aerobic bacteria, which break down waste more effectively than anaerobic bacteria. For the system to function properly, airflow, component cleanliness, and bacterial health must all be monitored and maintained consistently. What Happens Without Regular Maintenance Even a well-designed system like Hydro‑Action can develop serious problems if regular care is neglected. Bacteria Imbalance When the aerobic bacteria inside your system are not supported with enough oxygen or become overrun by anaerobic organisms, treatment efficiency drops. You may notice unpleasant odors or a decline in effluent quality. This imbalance increases the risk of environmental contamination and system failure. Filter and Diffuser Blockages Over time, filters and diffusers collect debris and biological buildup. When these components clog, airflow is restricted, starving the aerobic bacteria of oxygen. This reduces treatment efficiency and may activate your system's alarm. Clogged filters are one of the most common causes of minor failures that become major if ignored. Motor or Aerator Failure The aerator is a crucial component that delivers oxygen into the treatment chamber. If it fails, the system essentially reverts to an anaerobic state. These motors can burn out from overuse or become damaged due to exposure or clogging. Replacing a motor is far more expensive than regular service visits to inspect and clean the system. Key Maintenance Tasks for Peak Performance At Alternative Septic Management, we follow a detailed maintenance protocol specifically for Hydro‑Action systems. Inspections Our technicians perform a thorough system inspection every service visit. We check aerator operation, effluent levels, system alarms, and the condition of each treatment chamber. These routine checks help us spot wear on components and early signs of trouble before they become costly repairs or replacements. Cleaning Diffusers and Filters Clean filters and diffusers ensure consistent oxygen flow to aerobic bacteria. If these components become clogged, the entire treatment process slows down or stops. During maintenance, we remove, clean, and if needed, replace filters and diffusers to keep the system running efficiently. Testing Air Output We use professional equipment to test the air pressure produced by your aerator. If the air output falls below specifications, we investigate further to ensure that the motor, tubing, and diffusers are all working correctly. Low airflow is often the first sign of mechanical failure, so regular pressure checks are essential. Signs Your Hydro‑Action System Is Due for Service Routine maintenance is ideal, but certain warning signs may indicate that your system needs immediate attention. Alarm Activation Most Hydro‑Action systems are equipped with an alarm that alerts you to operational problems such as electrical failure, motor issues, or abnormal water levels. If your alarm sounds, do not ignore it. Checking and taking care of any issue quickly may prevent a serious backup or failure. Odors Around the System Foul or persistent odors near your septic system are a strong indication that the system is not processing waste properly. This could be due to a clogged filter, bacterial imbalance, or a failed aerator. Sluggish Drains or Backups If drains in your home begin to slow down or you experience minor backups, the issue may be connected to septic system performance. Early intervention through inspection and maintenance can often resolve the issue without expensive repairs.

Top 5 Warning Signs You Need Pump Repair on Your Aerobic Septic System

July 7, 2025
At Alternative Septic Management, we specialize in supporting Georgia homeowners with aerobic treatment units (ATUs) . One of the most critical components of an ATU is the pump. It plays a key role in transporting treated effluent to the drain field. When the pump starts to fail, system-wide problems can follow. Recognizing the warning signs early helps prevent serious damage, system backups, and costly repairs. 1. Slow Drains and Backups in the Home What It Looks Like One of the earliest signs of septic pump trouble is slow drainage in your sinks, tubs, or toilets. You might also notice wastewater backing up into household fixtures. These problems typically indicate that the pump is no longer moving effluent efficiently out of the tank. Why It Happens When the pump isn’t functioning properly, effluent builds up in the tank and has nowhere to go. This can cause pressure to build in the pipes and slow or reverse drainage. Ignoring this issue can lead to backups and unsanitary conditions. 2. Alarm Activation or Warning Lights Understanding Your System’s Alerts Most aerobic systems come equipped with alarms or indicator lights designed to alert homeowners to system malfunctions. If your alarm sounds or a warning light appears on the control panel, it’s your system telling you something is wrong, often with the pump. What It Could Mean High water levels in the tank Electrical problems preventing the pump from running Mechanical failure of the pump motor Even if everything else seems to be working, always take alarm signals seriously. A quick inspection can save you from a system failure later. 3. Unpleasant Odors Around the Tank or Drain Field Why Odors Matter Foul smells near your septic tank or drain field often signal trouble. In an aerobic system, odors suggest that wastewater isn’t being treated or moved out of the system correctly. When the Pump Is To Blame If the pump fails, partially treated effluent can accumulate in the tank. This creates an anaerobic environment, leading to odors similar to rotten eggs (hydrogen sulfide). These odors are not just unpleasant—they indicate incomplete treatment and potential health risks. 4. Standing Water or Wet Spots in the Drain Field Spotting the Problem During dry weather, your drain field should not have pooling water or overly wet soil. If it does, this may indicate that the pump isn’t properly dosing the drain field, allowing too much effluent to accumulate in one area. Possible Pump-Related Causes Uneven or infrequent dispersal of effluent Total pump failure causing overflow High-volume discharge overwhelming the field Standing water poses environmental concerns and can lead to long-term damage to your drain field infrastructure. 5. High Water Levels in the Septic Tank How To Check the Water Level Many aerobic systems are built with risers that allow visual inspection of the tank’s water level. If you observe water near the top or spilling into components it shouldn't reach, this is a sign the pump isn’t moving effluent as designed. Why It Happens When the pump stops working or is not operating on schedule, effluent builds up in the treatment tank. Continued water use in the home causes the tank to overfill, which may eventually trigger the high-water alarm or backflow into the house. What Causes Aerobic Pump Failure? Common Mechanical and Environmental Factors Understanding the source of pump failure can help prevent future problems. Here are some of the most frequent causes: Age and general wear over time Clogs caused by debris or a lack of filter maintenance Electrical issues, such as damaged wiring or failed float switches Overuse or increased water demand Poor system design or installation Routine inspections help identify these issues before they escalate into emergencies.
