Hastings Septic Co arranges septic tank pump-outs and AWTS servicing for the growing unsewered fringe around Thrumster, where new-estate blocks on Port Macquarie’s western growth corridor commonly rely on an aerated wastewater treatment system (AWTS) rather than town sewer. If you’ve just settled into a newly built home out here, working out what’s actually buried in the yard and what it needs matters more than anything else on this page.

Why is Thrumster different from the rest of Port Macquarie?
Thrumster is one of the fastest-growing pockets of the Port Macquarie-Hastings LGA: new estates, new roads and new subdivisions on what used to be rural land west of the CBD. That growth matters for septic because it’s the opposite pattern to most of established Port Macquarie, where town sewer has covered the older, built-up parts of the city for decades. Out on the Thrumster fringe, plenty of blocks simply aren’t connected to sewer, and new dwelling approvals there commonly come with an onsite sewage management system as a condition of development consent, either a conventional septic tank or, more often on these newer estates, an AWTS.
That distinction matters if you’re a first-time owner. Buyers moving from a sewered suburb into a Thrumster estate often assume “new house” means “connected to everything,” and are surprised to find a control panel or an inspection lid in the yard instead. This page is written specifically for that situation: a recently built or recently purchased unsewered property, rather than the older, more established pattern covered on our general Port Macquarie services page.
Does my new Thrumster property have a septic tank or an AWTS?
On new estate land like Thrumster, an AWTS is the more common installation, because many of these subdivided blocks were specifically approved with an aerated system where lot size or soil conditions ruled out traditional trench-based disposal. That’s not a rule though, some Thrumster properties on larger or older-titled parcels still run a conventional septic tank, so it pays to check rather than assume.
The quickest way to tell the two apart without digging anything up: a plain lid with no power connection is a conventional tank; a powered control box with a light or buzzer, plus sprinkler heads or drip lines across a defined patch of lawn, is an AWTS. Our guide to telling a septic tank from an AWTS covers the visible clues in more depth, including what a faint mechanical hum near the tank usually means. If you genuinely can’t tell after checking, send us a description or a photo of whatever’s visible and we’ll usually confirm the system type before you book anything.
What does owning a septic system for the first time actually involve?
If you’ve only ever lived on town sewer, an onsite system asks a bit more of you as the owner. A conventional tank works away passively by gravity and settling until it needs a pump-out, roughly every 3-5 years for most households, while an AWTS is a small powered treatment plant that needs regular scheduled servicing, commonly quarterly in NSW, on top of its own periodic desludge. Our guide to how a septic system works walks through what actually happens between the inlet pipe and the trenches or irrigation area, which is worth reading once so you know what you’re maintaining.
The other thing new owners on unsewered land need to know: in NSW, onsite sewage management systems generally require council approval to operate under section 68 of the Local Government Act 1993, and that approval is usually tied to keeping the system properly maintained, whether that’s pump-out records for a conventional tank or service reports for an AWTS. Port Macquarie-Hastings Council holds the approval details for individual properties, so if your settlement paperwork didn’t make the system type or its conditions clear, a call to council is the way to confirm it.
How much do septic and AWTS services cost around Thrumster?
Costs on the Thrumster fringe sit within the same indicative ranges we quote across Port Macquarie-Hastings, since it’s a similar travel distance from town as the rest of the western fringe. The table below sets out the two maintenance paths side by side.
| System type | Typical maintenance | Indicative cost | How often |
|---|---|---|---|
| Conventional septic tank | Pump-out by vacuum tanker | $350-$550 for a standard tank up to ~3,000 L with good access | Every 3-5 years |
| AWTS (aerated wastewater treatment system) | Scheduled service visit | $180-$330 per visit, or $650-$1,200 for an annual agreement of around four visits | Commonly quarterly in NSW |
| AWTS primary chamber | Periodic sludge pump-out | $400-$750 | Multi-year cycle, checked at each service |
These are indicative guide ranges only, not quotes; the exact price depends on your tank or system size, access, and condition, and is always confirmed before work starts. A septic tank pump-out or an AWTS service booking both start the same way: tell us your address and what’s visible in the yard, and get a free quote.
What should a new Thrumster homeowner do in the first year?
A handful of simple checks in the first year on a new unsewered block save trouble later.
- Find your approval paperwork. Your section 68 approval or the builder’s handover documents should state the system type and its servicing conditions. If you can’t locate it, Port Macquarie-Hastings Council can confirm what’s registered for your address.
- Locate the lid or control box, and note the brand. For an AWTS, the system brand is usually printed on or inside the control box lid, and it’s worth knowing before you ever need to call for a service.
- Check whether servicing has actually started. Some new builds come with an initial service period arranged by the builder or developer that lapses without anyone noticing. If you’re not sure whether your AWTS is on an active schedule, treat it as unconfirmed until you check.
- Don’t wait for the alarm to go off. An AWTS alarm usually means a pump, blower or float switch has already failed. Getting a service booked before that happens is cheaper and less stressful than reacting to a flashing light.
- Keep records from day one. A documented service history protects you at resale and satisfies council if your system is ever inspected.

Thrumster septic & AWTS FAQs
Is Thrumster on town sewer or is it all septic and AWTS?
It varies by street and by when a particular stage of the estate was developed; some newer sections are progressively connected to sewer infrastructure as it extends, while others remain on an onsite system. Your rates notice will show a sewer charge if you’re connected; if it doesn’t, you’re most likely on a septic tank or AWTS. Port Macquarie-Hastings Council can confirm the sewer status for a specific address if you’re unsure.
My new home has an AWTS. Who is responsible for servicing it?
As the property owner, you are responsible for keeping the system maintained and within its council approval conditions, regardless of whether the builder or a previous owner arranged the first service or two. That’s true even if nobody has explicitly told you a schedule exists. If you don’t have a service history, treat it as due for a check.
The builder said the AWTS servicing was “included.” How do I know if that’s still active?
Builder-arranged servicing periods are often time-limited and don’t always continue automatically. The safest approach is to ask for the last service date and provider directly, and if you can’t get a clear answer, book a check-up visit so you have a confirmed baseline rather than an assumption.
Can you take over AWTS servicing from a builder’s service company?
Yes. We can pick up servicing on a system regardless of who serviced it before, and a first visit establishes the system’s current condition even without old records, so a gap in the paperwork isn’t a barrier to getting back on schedule.
Do I need a pump-out if my new Thrumster home has an AWTS, not a conventional tank?
Yes, eventually. An AWTS still accumulates sludge in its primary chamber and needs a periodic pump-out on a multi-year cycle, in addition to its regular scheduled servicing. Sludge levels are checked at each service visit so this doesn’t come as a surprise.
What if I’m not sure whether my Thrumster block even has an onsite system?
Check your rates notice for a sewer charge, and look in the yard for either a plain inspection lid or a powered control box with sprinklers nearby. If both checks leave you unsure, send us your address and we can help confirm the system type as part of arranging a quote.
