Retrofitting Your Septic System With Aerobic Treatment Units (ATUs): The Process and Benefits for Property Owners

August 2, 2023

Alternative wastewater treatment solutions continue to gain traction as homeowners and commercial property owners become increasingly aware of the environmental implications of traditional septic systems.


Aerobic Treatment Units (ATUs) have emerged as a popular choice for those seeking a more efficient and environmentally friendly septic system. However, many property owners question whether it is possible to retrofit their existing conventional septic system with ATUs, and if so, what benefits they can expect.


Before delving into the specifics of the ATU retrofitting process, it is crucial to understand the advantages of upgrading to this advanced wastewater treatment technology. ATUs use aerobic (oxygen-rich) bacteria to more effectively break down waste, offering superior treatment capabilities compared to traditional septic systems, which rely on anaerobic bacteria. 


Consequently, ATUs reduce the likelihood of system failures, lower instances of groundwater contamination, and minimize nutrient pollution in water resources. Moreover, in some cases, ATUs may require smaller drain fields, providing the added benefit of increased usable land for property owners with limited space.


Retrofitting your traditional septic system with an ATU can enhance the performance of your septic system while significantly reducing its environmental footprint. This blog's objective is to guide you through the retrofitting process, discussing the reasons for considering such a project, the steps involved in retrofitting, cost factors, and the environmental and long-term financial benefits of upgrading to an ATU. 


Furthermore, we will provide valuable tips for maintaining and caring for your newly installed ATU system, empowering you to make informed decisions when seeking efficient and environmentally conscious wastewater treatment solutions.


Advantages of ATUs in Commercial Settings


In order to understand the benefits of using ATUs in commercial properties, it is essential to recognize the limitations of traditional septic systems. Conventional septic systems often struggle to break down waste effectively enough, which can result in increased maintenance needs, malodorous surroundings, and subpar wastewater treatment. 


Conversely, ATUs offer several advantages that make them a more viable choice for commercial properties:


1. Enhanced wastewater treatment: ATUs utilize aerobic (oxygen-rich) bacteria, providing a more efficient breakdown of waste compared to the anaerobic bacteria used in traditional systems.

2. Superior nutrient removal: Through more thorough wastewater treatment, ATUs can effectively eliminate a higher percentage of nitrogen and phosphorous, reducing nutrient pollution and protecting water resources.

3. High-strength wastewater compatibility: ATUs can process high-strength wastewater often produced in commercial settings, making them a practical choice for businesses such as restaurants, hotels, and large office complexes.

4. Space-saving design: ATUs typically demand smaller drain fields than traditional septic systems, which can save valuable real estate on commercial properties.


Adapting ATUs To Handle High-Strength Wastewater


Commercial properties often generate high-strength wastewater due to increased volumes and concentrations of waste compared to residential settings. ATUs can be adapted to handle the particular demands of commercial wastewater, offering more effective treatment than traditional septic systems. Here are some methods for adapting ATUs to handle high-strength wastewater in commercial applications:


1. Upgrading to a larger system: ATUs come in various sizes and capacities, and commercial properties may require a larger system to accommodate their specific wastewater needs. Consulting with a qualified professional will help you choose the appropriate sized ATU to effectively handle high-strength wastewater generated on your property.

2. Pre-treatment options: Implementing a pre-treatment stage within the ATU can help break down solids and minimize grease accumulation, providing more efficient primary treatment and ensuring compatibility with high-strength wastewater.

3. Incorporating supplemental treatment: In some cases, ATUs can be combined with additional treatment methods to address specific commercial wastewater challenges, such as nutrient reduction or disinfection.


Maintaining ATUs for Optimal Performance


Proper maintenance is critical for ensuring the efficient, long-lasting performance of your commercial ATU. By following these recommended maintenance practices, you can protect your investment and reduce the risk of system failure:


1. Regular maintenance checks: Schedule routine maintenance checks by a licensed professional to inspect and monitor the performance of your ATU and address any potential issues.

2. Pump-out frequency: Discuss with your septic professional the ideal frequency for pumping out your ATU system to prevent sludge and scum build-up, which could lead to system malfunctions or failures.

3. Adherence to best practices: Establish and enforce guidelines on waste disposal, including the proper disposal of grease and food waste to avoid overburdening the ATU.

4. Monitor system usage: Be aware of sudden changes in water usage and waste generation on your property, which can affect your ATU's performance. Address any unusual fluctuations promptly to prevent undue strain on the system.


Creating a Sustainable Environment for Future Generations


By integrating ATUs into commercial wastewater management, businesses can work toward creating a more sustainable and environmentally friendly future. Implementing this advanced treatment technology in commercial settings not only ensures adequate wastewater treatment and reduced pollution but also paves the way for proactive and sustainable business practices. By investing in ATUs, commercial property owners can demonstrate their commitment to preserving the environment for generations to come.
