A farm stay or glamping site looks nothing like a house on paper, but it still needs somewhere for the wastewater to go, and that’s the part landowners across regional NSW most often underestimate when converting a paddock or bush block into paid accommodation. A cluster of bell tents or safari cabins, a shared amenities block, maybe a communal kitchen or breakfast hamper service, all add up to a wastewater load a standard household septic tank was never sized for, and council approval will reflect that reality rather than the fact that each “dwelling” is technically just canvas and a timber platform.
This guide sets out how wastewater is generally handled for farm stay and glamping accommodation in NSW: what makes the load different from a house, the system types that tend to suit this kind of site, what council approval typically involves, and how servicing needs to be scheduled around a business that runs on bookings rather than a steady household routine.
Why glamping and farm stay wastewater doesn’t behave like a house
A single house has a reasonably predictable occupancy and a fairly even daily use pattern. A glamping or farm stay site breaks that model in a few specific ways:
Multiple accommodation units on one wastewater system. Whether it’s four bell tents or a dozen safari cabins, most sites run all their accommodation off one shared system rather than a septic tank per tent. That means the system has to be sized for the site’s total guest capacity at full occupancy, not for a single “household,” and getting that sizing wrong at the design stage is a very common problem on rural tourism conversions.
Sharp occupancy swings. A farm stay that sleeps four people most weeknights and twenty over a long weekend or school holiday period puts a genuinely uneven load on the system. Design and servicing both need to account for the peak, not the average, because a system that copes fine on a quiet Tuesday can be pushed hard on a fully booked Saturday.
Outdoor and shared ablution facilities. Many glamping setups centre on a shared amenities block, composting or flush toilets, hot showers, sometimes an outdoor kitchen, rather than individual ensuites in every tent. That concentrates flow into fewer points at predictable times of day (morning showers, evening use after dinner) which is a different hydraulic pattern to a scattered household load.
A commercial kitchen component, if you’re feeding guests. Breakfast hampers prepared on-site, a communal camp kitchen, or a licensed restaurant component all generate fats, oils and grease that need to be intercepted the same way any commercial kitchen’s would be, on top of whatever the accommodation itself contributes. If food is being prepared for guests rather than guests self-catering entirely, a grease trap is very likely part of what your approval requires; our grease trap cleaning page covers how that side of things is typically serviced.
What system types tend to suit a farm stay or glamping site?
There’s no single answer, it depends on guest numbers, site topography, water availability and what your council’s onsite sewage management (OSSM) framework requires, but a few approaches come up repeatedly on rural tourism conversions:
- A single AWTS, sized for peak occupancy. Where a site can support the irrigation area an AWTS needs, this is common because it treats wastewater to a higher standard before dispersal, suiting sites where land for a large conventional trench field isn’t available or the ground doesn’t drain reliably.
- A package or commercial-scale treatment plant. Larger sites with double-digit guest capacity sometimes need something closer to what a small caravan park runs, a commercial-grade system designed and certified for the site’s actual peak load, rather than a scaled-up residential unit.
- Composting toilets paired with a separate greywater system. Some off-grid and lower-impact operators remove blackwater from the equation entirely this way, with a simpler greywater system handling showers and hand-washing. It can suit remote or sensitive sites well, but it’s a decision to make with your designer and council early, not after the tents are up.
- Staged systems for a business that’s growing. Starting with four tents but planning to expand to twelve? It’s worth designing and getting approval for the eventual scale from the outset, even if you build it in stages, rather than hitting a wall later.
What does council approval actually require?
Any accommodation business generating wastewater beyond a single residential dwelling needs its onsite sewage management system approved on that basis, sized for the site’s actual guest capacity and use pattern, not assessed as if it were a house. In practice that generally means:
- Development consent covering the accommodation use itself, typically specifying or referencing the wastewater infrastructure required.
- An OSSM approval-to-operate from your local council, sized for peak occupancy across all accommodation units combined, plus any camp kitchen or dining facility.
- A grease trap sized for your kitchen’s actual output, if you’re preparing food for guests on-site. Requirements generally mirror what applies to any other food business; our grease traps for food businesses guide covers the detail, worth reading even if your operation is small.
- Ongoing servicing conditions, which for an AWTS commonly mean quarterly servicing by an accredited provider, the same requirement as a residential aerated system, just against a larger unit designed for higher throughput.
Requirements differ between council areas across NSW, and an approval for a farm stay in one LGA won’t automatically transfer to a different council, so this is genuinely a “check with your specific council” situation rather than one where a general rule of thumb is safe to rely on.
Servicing a glamping or farm stay system
Because the load swings so hard between quiet periods and fully booked peaks, a fixed, calendar-based servicing schedule is often the wrong tool on its own. What tends to work better in practice:
- Servicing timed ahead of known peak periods (long weekends, school holidays, wedding season if that’s part of your offering) rather than waiting for a fixed quarterly date that might land mid-peak.
- Sludge and grease trap checks calibrated to actual bookings, not just the calendar, since a site quiet for two months and then hosting three back-to-back fully booked weekends needs a different rhythm to one running steady moderate occupancy year-round.
- One coordinated schedule covering the wastewater system and any grease trap together, since both are driven by the same occupancy pattern and are simpler to manage as one relationship rather than two.
Indicative costs
| Job type | Indicative range | Notes |
|---|---|---|
| AWTS scheduled service (per visit) | $150-$300 | Scales up for larger, higher-capacity commercial-style units |
| AWTS primary chamber desludge | $400-$700+ | Periodic, on a multi-year cycle, more often on heavily used sites |
| Grease trap pump-out (small commercial) | $250-$600+ | For camp kitchens and breakfast preparation areas |
| Septic / pre-purchase or design-stage inspection | $250-$500 | Useful before committing to a system size or expansion plan |
These are indicative guide ranges only, not quotes, and a commercial-scale or multi-unit system will generally sit above these residential-scale figures once its actual capacity is factored in. Every job is quoted for the specific site once guest numbers, system type and access are known.
Farm stay & glamping wastewater FAQs
Can we just install a bigger version of a normal household septic tank?
Not on its own, in most cases. A larger tank alone doesn’t necessarily give you the treatment standard or properly sized dispersal area a multi-unit accommodation business needs approved. Your system needs to be designed and approved around your actual peak guest capacity, a job for a qualified designer working with your council’s OSSM requirements, not a simple size-up of a residential unit.
Do we need a grease trap if guests only get a continental breakfast hamper?
Very likely, yes, if any food preparation happens on-site rather than hampers arriving fully assembled. Even modest on-site food prep generates fats and oils that need intercepting the same way a small café’s would. Check the specifics against your kitchen setup with your council or ask us when you enquire.
We’re starting with four tents but plan to expand. Should we design for that now?
Worth discussing with your system designer before you commit to a size. Approving and building for your eventual scale, even in stages, is usually more straightforward than hitting a capacity wall later and rebuilding a system that’s already serving guests.
How does servicing frequency work for a site with wildly uneven bookings?
The practical approach is timing services around known peaks rather than a fixed calendar date, and calibrating sludge and grease checks to actual recent occupancy. Tell us your booking pattern when you enquire so a schedule can be set that fits how the site is actually used.
Does this apply outside the Port Macquarie-Hastings region?
The general principles (sizing for peak occupancy, grease trap obligations for on-site food prep, council approval based on actual use) apply broadly across NSW, though the specific approval process varies by council. If your site is elsewhere in NSW, your local council is the authority to confirm requirements with.
