Education

Septic Tank vs AWTS — which is right for your block?

The right system depends on your land, soil, household size and council zoning. Here’s the honest, plain-English breakdown.

 

Traditional Septic Tank

Proven, low-maintenance gravity system. Ideal for larger blocks with suitable soil.

AWTS (Aerated System)

Modern aerobic treatment producing high-quality effluent safe for surface irrigation.

Not sure which one? That’s literally our job. Book a site assessment — we’ll tell you the right system for your land before you spend a cent.

 

AWTS specialists

Modern aerated systems — installed properly, serviced reliably.

AWTS units give you treated water you can safely irrigate above ground — perfect for smaller acreage, sloped sites, or council areas where a traditional trench field isn’t approved. We install, commission and quarterly-service all major brands.

“We had an issue with water not draining away from our property during heavy rainfall. Gave these guys a call and they were able to fit us in within 24 hours. Noah was thorough and addressed our concerns. They booked in our drainage rectification promptly and we are feeling a lot more confident for when the next deluge hits. Highly recommend.”

FAQ

Blocked drain questions — answered.

Do I need council approval for a new septic or AWTS?
Yes — any new install, replacement or major upgrade requires council approval. We prepare the application, arrange soil testing, lodge it on your behalf and manage every inspection through to final certification.
From approval, most installs are completed in 2–5 days on site. Total project time, including soil tests and council approval, is typically 4–8 weeks depending on your local council.
Standard septic tanks: every 3–5 years for an average household. AWTS units: serviced quarterly with pump-outs every 3–5 years depending on usage. We can set you up on a scheduled service plan.
A traditional septic uses gravity and a soil drain field. An AWTS aerates and treats the wastewater to a higher standard so it can be safely irrigated above ground. AWTS suits smaller, sloped or sensitive sites; septic suits larger blocks with good soil.
Wherever possible, yes. We inspect, diagnose and quote a repair first. A full replacement is only recommended when the tank or field has structurally failed or no longer meets council compliance.
Yes. Every septic and AWTS install is backed by our written Lifetime Workmanship Guarantee — issued on your invoice with no fine print.
Yes — fully QBCC licensed for drainage, on-site sewerage and wastewater, plus public liability insurance on every job. Licence numbers appear on every quote and certificate.
It depends on system type, site conditions, soil and access. We provide a fixed written quote after a proper on-site assessment — no estimates over the phone, no surprise variations later.
