Best shots: the whole tank (helps me judge capacity), any visible damage, and the outlet so I can size the pipework.

Conventional or aerated? An honest guide

If you're building, replacing a failed system, or your old septic is at the end of its life, the first decision is the system type — and it's mostly decided by your site, your council, and your budget.

Conventional septic

The classic tank-and-absorption-trench setup. Fewer moving parts, no power required, minimal ongoing servicing. Needs enough land area and suitable soil for the trenches, and council sign-off on the design. Usually the cheaper option where your site allows it.

Aerated system (AWTS)

A powered system that treats wastewater to a higher standard — the treated water can typically be reused on gardens via irrigation. Suits smaller blocks and sites where trenches won't work. Requires power and regular servicing under NSW/Vic rules.

Not sure which your block needs? That's exactly what the consult is for — tell Marcus about your property and you'll get a straight recommendation, including whether your council has a preference.

How an install works

Site consult

We look at your block, soils, existing system (if replacing), and what your council requires — then recommend a system and give you a firm quote.

Approvals

Septic installs need council approval. We guide you through the application so it's done right the first time — the step most people find hardest.

Installation

Tank, trenches or irrigation, and all plumbing connections installed and plumbed by a licensed plumber to the approved design.

Sign-off

Final inspection, council sign-off, and a walkthrough of how to look after your system so it lasts.

Septic questions

Do I need council approval to install or replace a septic system?

Yes — in both NSW and Victoria, installing or replacing an on-site wastewater system requires council approval. It's the part of the process most owners find confusing, so we guide you through it as part of the job.

How much does a septic system cost?

It depends heavily on the system type, your site, and council requirements — so every job is quoted individually after a consult. Call Marcus to talk through your property.

How do I know if my old septic needs replacing?

Warning signs include sewage smells, slow drains across the whole house, soggy ground or unusually green grass over the trenches, and backups after rain. Some problems are repairable — replacement is the honest answer only when it's genuinely needed.

Can you replace just the tank or just the trenches?

Sometimes — it depends on the condition of each part and what council will approve. A site inspection gives you a straight answer.
