What To Do When Your ATU Alarm Sounds
An aerobic treatment unit (ATU) is a critical component of modern septic systems, especially in environmentally sensitive or high water table areas. At Alternative Septic Management, we understand how alarming it can be when your ATU system sets off an alert. Understanding what your ATU alarm means and how to respond promptly can protect your home, your system, and your environment.
Why ATU Alarms Are Important
ATU alarms are designed to be your first line of defense when something isn't functioning as it should. These systems are equipped with control panels that monitor key operational metrics to ensure efficient treatment of wastewater.
Purpose of the Alarm System
The primary role of the alarm system is to alert the homeowner or property manager to irregular conditions that could compromise the function or safety of the system.
What It Monitors
- Air pressure – Ensures the aerator or blower is functioning properly to sustain aerobic bacteria.
- Pump function – Detects if pumps that move effluent are working or have failed.
- Effluent levels – Monitors for high water levels that can indicate a backup or drainage issue.
If any of these components fall outside of normal operating parameters, the alarm will sound or flash to prompt immediate attention.
Common Causes for an ATU Alarm
Knowing the possible causes of an alarm can help you assess the situation more calmly and accurately.
Power Interruptions
Power outages or tripped breakers can disable the aerator or pumps. Without power, the system can’t operate, and alarms are triggered to reflect the lack of aeration or pumping.
Equipment Malfunction
Mechanical issues are common, particularly with older systems. This includes:
- Faulty air compressors or blowers
- Malfunctioning submersible pumps
- Timer or float switch failure
Excess Water From Heavy Rainfall
Georgia’s rainy season can overwhelm septic systems. Infiltration of stormwater can flood the tank, elevate effluent levels, and trigger alarms.
Clogged or Frozen Lines
Debris or roots in the pipes can obstruct flow. In colder months, shallow or exposed lines may freeze, halting proper function.
Immediate Steps To Take When the Alarm Sounds
It’s natural to panic when a system alarm goes off, but taking the right steps quickly can prevent further damage.
Stay Calm and Follow These Steps:
- Silence the alarm if possible.
Most control panels have a button to silence the audio portion of the alarm. This doesn’t stop the alarm condition—it simply quiets the alert. - Check for power to the system.
Inspect your electrical panel for tripped breakers. Restore power if safe to do so. - Avoid using additional water.
Stop running appliances and minimize water usage until the problem is resolved. This prevents further strain on the system. - Visually inspect the control panel.
If accessible, look for indicator lights or codes that can help identify which component is malfunctioning.
When To Call a Septic Professional
While some alarm causes are temporary or resolvable at home, others require professional service. Contact Alternative Septic Management if:
- The alarm persists for more than 24 hours.
- You notice water backing up into your sinks, toilets, or tubs.
- There are signs of surface pooling or soggy areas near the drain field.
These signs suggest a serious issue, such as a pump failure or a saturated drain field, and need expert evaluation.

Preventing Future Alarm Activations

Regular Inspections and Maintenance
Scheduling biannual or quarterly inspections ensures early detection of wear and tear, clogged components, or bacterial imbalances.
Upgrading Aging System Components
If your system is more than 10-15 years old, consider replacing outdated pumps or blowers with modern, energy-efficient units that are less prone to failure.
Managing Household Water Usage During Storms
Spread out laundry and dishwasher use during and after heavy rain. Ensure downspouts and gutters direct water away from the septic area.
