Why Your AWTS Is Different from Traditional Septic Systems
Unlike conventional septic tanks, your AWTS represents advanced technology that transforms wastewater through a sophisticated multi-stage process:
Your system works tirelessly to convert household waste into reusable water through a remarkable four-stage journey:
Primary Treatment where solids separate and begin breaking down, flowing into the Aeration Chamber where beneficial bacteria energised by carefully calibrated oxygen levels, transform waste into safer compounds. This flows to the Clarification Chamber where remaining particles settle before the final Disinfection Stage produces water clean enough for garden irrigation and other approved uses.
This advanced process removes more solid matter than traditional systems, preventing clogs while producing environmentally safer water you can actually reuse, but only when properly maintained.
Systems in poor condition can not only pose a serious health risk to your family and the environment but often become significantly more costly in the long term than following a regular servicing schedule. The best way for your system to operate effectively and reliably is through our professional Quarterly Maintenance Program, as required by NSW Health and local councils.

Frequently Asked Questions About AWTS Quarterly Inspections
Are quarterly inspections for AWTS systems now mandatory in NSW?
Yes. Recent NSW regulations require all Aerated Wastewater Treatment Systems to undergo professional inspection every three months. This new requirement aims to ensure environmental protection, public health safety, and compliance with updated wastewater management standards. Failure to maintain these regular inspections can result in council penalties and potential restrictions on system use.
How are AWTS different from traditional septic tanks?
Traditional septic tanks rely primarily on anaerobic (without oxygen) bacterial processes and simple settlement of solids. AWTS systems incorporate mechanical aeration to promote aerobic (oxygen-using) bacteria that break down waste more efficiently. This results in higher quality effluent, fewer odors, reduced environmental impact, and the ability to reuse treated water for irrigation. However, this advanced technology requires more regular professional maintenance than conventional septic systems.
What happens during an AWTS quarterly inspection?
Our comprehensive AWTS inspection includes checking all mechanical components (pumps, blowers, aerators), measuring sludge levels, inspecting filters and cleaning as needed, verifying disinfection system function, testing alarm systems, assessing bacterial activity, and sampling effluent quality. We provide complete documentation for council compliance and recommendations for optimal system operation.
What are signs my AWTS system needs immediate attention between quarterly services?
Don't wait for your scheduled inspection if you notice: unusual odors around your system or drain field, gurgling sounds in plumbing, slow drains throughout your home, soggy areas or lush growth near your system, alarm activation, or visible wastewater backing up. These symptoms indicate potential problems requiring immediate professional attention to prevent system failure or environmental contamination.
Can I perform basic septic maintenance myself between professional inspections?
While quarterly professional inspections are mandatory, homeowners can help maintain system performance by: being mindful of what enters your system (avoiding harsh chemicals, grease, non-biodegradable items), conserving water to prevent system overload, keeping surface water away from your drain field, and monitoring for warning signs of problems. However, never attempt to open or service technical components of your AWTS system.
How does proper AWTS maintenance protect my property value?
A well-maintained wastewater system is crucial for property value in areas without municipal sewage connections. Potential buyers increasingly request documentation of regular professional maintenance, especially with new NSW quarterly inspection requirements. Properties with maintenance compliance history and properly functioning systems typically command higher resale values and faster sales than those with neglected systems requiring expensive repairs.
What happens if my AWTS fails inspection or requires repairs?
If we identify issues during your quarterly inspection, we'll provide detailed recommendations for necessary repairs. Minor adjustments can often be made during the inspection visit. For more significant repairs, we'll provide a comprehensive assessment and quote. We work with you to schedule repairs promptly to restore system function and maintain compliance with council requirements. Our goal is to address small issues before they become costly emergencies.
How do seasonal changes affect my septic system maintenance needs?
AWTS performance can vary with seasonal changes. Heavy rainfall can saturate drain fields and affect system efficiency. Holiday periods often mean increased household occupancy and system load. Cold weather can temporarily reduce bacterial activity. Our quarterly inspection schedule ensures your system receives professional attention through all seasonal variations, with technicians adjusting settings and treatments to optimize performance year-round
