Aerobic Treatment Unit (ATU)

What is an ATU Septic System?

An Aerobic Treatment Unit (ATU) is a type of onsite wastewater treatment system designed to treat and dispose of domestic wastewater. Unlike traditional septic systems that rely on anaerobic bacteria (which operate in the absence of oxygen), ATUs use aerobic bacteria, which require oxygen to function. In an ATU system, oxygen is injected into the treatment tank to stimulate the growth of aerobic bacteria, which break down organic matter and pathogens in the wastewater more efficiently. This enhanced bacterial activity results in more thorough treatment of the wastewater before it is discharged into the environment. ATUs are commonly used in areas where soil conditions are unsuitable for traditional septic systems, or where advanced treatment is necessary to protect sensitive water bodies or public health. They may also be installed in homes with smaller lots or high groundwater tables. Overall, ATUs offer a more effective and environmentally friendly alternative to traditional septic systems, providing higher levels of treatment for wastewater before it is released back into the environment.

Key differences between an ATU system and a conventional septic system

  • System Components: ATUs include additional components compared to conventional septic systems. In addition to the septic tank, ATUs typically incorporate aeration equipment such as air blowers or pumps to inject oxygen into the treatment tank, creating aerobic conditions for the bacteria to thrive. They may also include additional treatment
  • Electrical Requirements: ATUs often require electrical power to operate the aeration equipment and other mechanical components. This means that electrical wiring must be installed to power the system, which may require coordination with an electrician and additional considerations during installation.
  • Treatment Process: The treatment process in an ATU is aerobic, meaning it relies on aerobic bacteria that require oxygen to break down organic matter and pathogens in the wastewater. In contrast, conventional septic systems rely on anaerobic bacteria that operate in the absence of oxygen. The aerobic treatment process in ATUs typically results in more thorough treatment of the wastewater before it is discharged into the environment.
  • Site Considerations: The installation of an ATU may require additional site considerations compared to a conventional septic system. This includes factors such as space requirements for the aeration equipment, proximity to electrical power sources, and potential noise or odor concerns associated with the operation of the system.
  • Regulatory Requirements: ATUs may be subject to different regulatory requirements compared to conventional septic systems, particularly in areas with stringent wastewater treatment regulations. This may include specific permitting, inspection, and maintenance requirements to ensure compliance with environmental and public health standards.

ATU Inspections

Aerobic Treatment Units (ATUs) typically require more maintenance compared to traditional septic systems because ATUs involve additional mechanical components, such as air blowers or pumps, to inject oxygen into the treatment tank and maintain aerobic conditions for the bacteria. The frequency of maintenance and inspection for ATUs can vary depending on factors such as system size, usage, manufacturer recommendations, and local regulations. However, in general, ATUs should be inspected and serviced more frequently than conventional septic systems to ensure optimal performance and prevent issues. Proper maintenance and regular inspections are critical for maximizing the lifespan and efficiency of ATUs and ensuring compliance with regulatory requirements. Homeowners should work closely with qualified professionals familiar with ATU systems to develop a maintenance schedule tailored to their specific system and usage needs.

ATU Installations

The installation of an Aerobic Treatment Unit (ATU) is more expensive compared to a conventional septic system installation because of its added complexity which stems from the additional components, electrical requirements, and treatment process involved. Homeowners considering the installation of an ATU should work closely with qualified professionals familiar with these systems to ensure proper design, installation, and compliance with regulatory requirements.
