If you’re a homeowner with a septic tank or Aerated Wastewater Treatment System (AWTS), regular servicing is not just recommended — it’s critical. Proper maintenance ensures your system functions efficiently, avoids costly repairs, and protects your property and the environment. In this blog, we’ll break down how often you should service your AWTS or septic tank, common signs of trouble, servicing procedures, environmental impacts, and what to do when problems arise.
How Often Should You Service a Septic Tank or AWTS?
AWTS Servicing Frequency
AWTS systems are more complex than traditional septic tanks. They rely on a combination of aeration chambers, pumps, filters, and bacteria to break down waste. To keep everything running properly, these systems must be serviced every three months by a qualified technician — and in most Australian states, this is a legal requirement.
Routine servicing ensures:
- Proper oxygen levels in the aeration tank
- The chlorinator is functioning and stocked
- Pumps and alarms are operating correctly
- Effluent is being safely treated and dispersed
Septic Tank Maintenance Schedule
– Conventional septic tanks don’t have mechanical components, but they still need regular pumping to prevent solids from overflowing into the absorption trench. Typically:
– Every 3–5 years: Full pump-out of sludge and scum
– Every 12–24 months: Inspection of levels, tank condition, and drainage fields
Regular inspections can identify early issues such as root infiltration, broken baffles, or blocked drain lines — all of which are much cheaper to fix when caught early.
What Happens During a Professional Service?
A typical septic or AWTS service includes:
- Checking and cleaning filters
- Measuring scum and sludge levels
- Testing aerators and pumps
- Replacing chlorine tablets or UV bulbs (AWTS only)
- Checking the control panel and alarms
- Inspecting the disposal area for pooling or overflow
- Recording the service for council compliance
By keeping up with these services, you’re not just ticking a box — you’re extending the life of your system and protecting your investment.
The Environmental Benefits of Proper Maintenance
- Beyond protecting your home and wallet, regular septic and AWTS servicing helps safeguard the environment. Failing systems can:
- Contaminate local waterways with untreated effluent
- Spread bacteria, viruses, and nutrients that fuel algae blooms
- Harm wildlife and soil ecosystems
- Pollute drinking water supplies
A well-functioning system filters and treats wastewater naturally, safely returning it to the ground or dispersing it through irrigation without harm.
Is Servicing Legally Required?
Yes — especially for AWTS systems. In New South Wales, Queensland, and other parts of Australia, homeowners are required by law to have their AWTS systems serviced quarterly by an accredited technician. Most local councils will request proof of servicing, and failing to comply can lead to fines or compliance notices.
