A septic non-compliance notice from council in NSW is a formal statement that your onsite sewage management system isn’t meeting its approval conditions, and it typically comes with a required response, ranging from a straightforward pump-out and inspection through to a full system upgrade, on a stated timeframe. The letter can look alarming, but the practical path through it is usually simpler than the wording suggests: understand exactly what was found, get it properly assessed, and respond to council with a plan rather than silence. This guide walks through what these notices generally cover, realistic timeframes, and how a sensible response typically plays out. It’s general information, not legal advice, and every council’s process and wording differs, so treat the specifics of your own notice as the authority, not this page.
What is a septic non-compliance notice?
Under section 68 of the Local Government Act 1993, onsite sewage management systems in NSW generally need council approval to operate, and that approval comes with conditions: servicing intervals, maintenance standards, and sometimes physical requirements around setbacks or effluent quality. A non-compliance notice, sometimes called a notice to comply, an order, or a rectification notice depending on the council and the legislation it’s issued under, is council formally telling you that an inspection, complaint, or records review has found your system isn’t meeting one or more of those conditions.
Notices typically arise from one of a handful of situations:
- A routine or complaint-triggered inspection finds a failing trench, surfacing effluent, a structural tank problem, or a system that’s clearly overloaded for the property’s occupancy.
- A servicing gap on an AWTS, where required quarterly (or otherwise scheduled) reports haven’t been lodged, or a service contract has lapsed.
- An unregistered or unapproved system, discovered through a property sale, a renovation application, or a records audit, where no valid approval exists at all.
- A neighbour or environmental complaint, most seriously where effluent is suspected of reaching a waterway, a drain, or a neighbouring property.
Our NSW septic rules guide covers the underlying approval framework these notices sit within if you want the fuller picture of how approvals to install and operate work.
What does a typical notice ask you to do?
The specifics vary by council and by what was actually found, but most notices set out three things: the finding, what’s required to fix it, and a deadline. Common requirements include:
- Arrange an overdue pump-out or full tank clean, often the fastest and cheapest item on the list, and sometimes the whole of what’s required.
- Book a professional inspection to assess the system’s actual condition and report back to council.
- Bring AWTS servicing current and provide evidence of an active service contract and up-to-date reports.
- Undertake repairs, a failed baffle, a collapsed lid, damaged pipework, generally by a licensed plumber.
- Commission a site assessment for an upgrade or replacement, the most involved response, required where the existing system genuinely can’t be brought into compliance as it stands, for example where absorption trenches have failed outright or a property’s occupancy has outgrown its approved system capacity.
Timeframes range from a matter of weeks for something like an overdue pump-out, to several months for a full system upgrade requiring design and installation. If a stated deadline genuinely isn’t achievable, most councils will engage constructively with a property owner who’s clearly acting in good faith and asks for an extension early, rather than one who goes quiet until the deadline passes.
How should you actually respond?
- Read the notice properly before doing anything. Work out exactly what was found, what’s required, and by when. If any of it is unclear, ring the council’s environmental health or development team and ask them to explain it in plain terms, this is a normal call for them to field.
- Don’t assume the fix is bigger than it is. A notice citing “system not operating satisfactorily” can mean anything from an overdue pump-out to a failed trench needing full replacement. Get the system properly assessed before assuming the worst, or spending money on the wrong fix.
- Book a septic inspection or the specific work requested. If the notice asks for an inspection, book one that produces a written report you can hand to council. If it asks for a pump-out, book that; a tank that’s simply overdue is often the entire issue.
- Get quotes and a realistic timeline before you reply. Council generally wants to see that you’re taking genuine, resourced action, not just a promise. Having an inspection booked, or a quote in hand for the required repair, gives your response substance.
- Reply in writing, even if you’ve also spoken by phone. Set out what you’ve already arranged, what the realistic timeline is, and ask for confirmation that it’s acceptable. A paper trail protects you if anything is disputed later.
- Keep every record. Inspection reports, pump-out dockets, service reports, invoices, and copies of all correspondence with council. If the matter is ever escalated, or the property is sold, this is exactly the documentation that answers questions before they’re asked.
- Follow through on the timeline you’ve committed to. Councils are generally far more tolerant of a property owner working steadily through an agreed plan than one who’s stopped responding.
What happens if you ignore a notice?
We won’t quote specific penalty figures, they vary and change, and every council administers enforcement differently. In general terms, ignoring a valid notice can escalate to formal orders, fines, and in serious or repeated cases, council-directed rectification carried out at the owner’s cost. A system that’s genuinely polluting a waterway can also draw attention from the NSW EPA, separately from anything council does. The practical reality for most owners is that engaging early, even just to ask a clarifying question or request a realistic extension, keeps a notice a manageable administrative matter rather than something that escalates.
Does a non-compliance notice affect selling the property?
Yes, potentially significantly. An unresolved council order against a property is the kind of material fact that must be disclosed to a purchaser, and a purchaser’s solicitor will typically uncover an open order through a Section 10.7 certificate search or a direct records check with council. Our Section 10.7 disclosure guide covers how that certificate and a records search interact, and what a vendor is expected to disclose. Resolving a notice before listing, or at minimum having a clear, documented plan and cost estimate in hand, generally makes for a far smoother sale than leaving it as an open question for a buyer’s solicitor to raise mid-contract.
What if the notice relates to a system you’ve just inherited through a purchase?
It happens more often than you’d think: a notice was issued to the previous owner, wasn’t fully disclosed or resolved before settlement, and now sits with your name on the title. Councils generally treat the current owner as the responsible party regardless of when the underlying issue began, so the practical path is the same as for any other notice, get it assessed, respond with a plan, and keep records. If you believe the issue was concealed during the sale, that’s a conveyancing and legal question separate from the compliance response itself, and worth raising with your solicitor. Our PMHC on-site sewage management approval guide is a useful starting point for understanding what approval should have existed for the property in the first place.
Septic non-compliance FAQs
What’s the difference between a notice to comply and a formal order?
Terminology varies by council, but broadly, an initial notice is often a request to rectify within a stated timeframe, while a formal order carries stronger legal weight. Read your specific document carefully, or ask council directly.
How quickly do I need to respond?
Notices generally state a deadline for the required action, which can range from a few weeks for something like an overdue pump-out to several months for a system upgrade. If you can’t meet the stated timeframe, contact council before the deadline passes and ask about an extension, most councils respond far better to that than to silence.
Can I fix the problem myself to save money?
Pump-outs must be carried out by appropriately licensed liquid-waste operators, and any plumbing or drainage repair must be done by a licensed plumber. DIY work on either front risks making the compliance position worse, not better.
Does a non-compliance notice mean my system needs full replacement?
Not necessarily, and often not at all. Plenty of notices are resolved with an overdue pump-out, a repair, or bringing AWTS servicing current. Full replacement is generally reserved for systems that have genuinely failed structurally or are undersized for the property’s occupancy, which an assessment will confirm one way or the other.
Who do I actually talk to at council about a notice?
The letter should include a contact, typically someone in the environmental health or development and environment team. If not, the council’s general switchboard can direct you, and can explain the finding in plain terms if the wording is unclear.
