AWTS Servicing — Why Regular Maintenance Matters

Keep Your Wastewater System Safe, Compliant & Working at Its Best

Aerated Wastewater Treatment Systems (AWTS) must be serviced regularly to keep them operating safely and efficiently. In NSW, NSW Health requires all AWTS units to be serviced every 3 months by a qualified technician. This ensures your system continues to treat wastewater correctly and protect your home, your land, and your family’s health.

Whether your system is brand-new or decades old, regular servicing is essential for long-term performance.

Why Do I Need to Service My AWTS?

1. To Keep Your System Compliant

Local councils and NSW Health require AWTS units to be serviced at least quarterly. Missing services can result in:

• Non-compliance notices

• Fines or restrictions

• Issues if selling or leasing your property

Regular servicing keeps you fully compliant.

2. To Protect Your Health & Property

An unserviced AWTS can:

• Produce poorly treated water

• Cause odours or wet, boggy areas

• Allow contaminants to enter your soil or waterways

Servicing ensures the bacteria inside your system are working effectively and that all chambers and pumps are functioning as designed.

3. To Prevent Breakdowns & Expensive Repairs

Small issues in an AWTS can escalate quickly if left unchecked. Routine servicing helps identify:

• Blockages

• Failing components

• Low chlorine levels

• Pump or blower problems

Catching problems early can save thousands in repairs and prevent system failure.

4. To Maintain Water Quality for Safe Irrigation

Your treated water must meet Australian standards before being released to your irrigation area. Regular servicing ensures:

• Clear, odourless water

• Balanced pH levels

• Correct chlorine dosage

• Safe conditions for irrigation areas, gardens & lawns
