Restaurant FOG Compliance Requirements: What Australian Operators Actually Need to Do

The health inspector arrives at 10 am on a Tuesday. Your kitchen has been running flat out since six. The trap was last serviced eight months ago and you're not sure when the next one is due. The inspector asks for your pump-out records. You don't have them.

That scenario plays out across Australian commercial kitchens more often than most operators expect. FOG compliance, the rules around fats, oils, and grease entering the sewer system, covers more than just scheduling a clean. It includes the type of equipment you have, how it's maintained, what records you keep, and what your trade waste agreement with your water authority actually requires.

This article walks through the practical requirements so you know what you're dealing with before the next inspection.

What FOG Compliance Actually Covers

FOG stands for fats, oils, and grease. When these enter the sewer in significant quantities, they cool, solidify, and cause blockages. Water authorities across Australia regulate this through trade waste agreements, which are contracts between your business and the local water utility that govern what you're allowed to discharge.

Compliance with those agreements typically involves four things:

• Having the right grease arrestor or interceptor installed and sized correctly for your kitchen output
• Cleaning and pumping that device at the frequency your agreement specifies
• Keeping records of every service, including contractor details and waste disposal manifests
• Reporting to your water authority if you upgrade your kitchen, change your menu, or alter your discharge significantly

Failing any one of these can result in a penalty notice, a requirement to upgrade your equipment at your cost, or suspension of your trade waste agreement, which means you can't legally operate.

The Role of Your Trade Waste Agreement

Every commercial food premises in Australia that connects to a reticulated sewer system needs a trade waste agreement with the local water authority. These agreements are not one-size-fits-all. Sydney Water, Melbourne Water's licenced retailers, SA Water, and Queensland Urban Utilities all publish their own trade waste guidelines, and the specific requirements, pump-out frequency, grease arrestor capacity, approved contractor standards, vary between them.

If you're unsure what your agreement says, the first step is to find and read it. Your water authority's website will have the relevant guidelines. Sydney Water's trade waste requirements are published at sydney.water/trade-waste and Melbourne Water's licensed retailers each publish their own. The Australian Water Association maintains resources on trade waste frameworks across jurisdictions.

Pump-Out Frequency: What the Rules Say

Most trade waste agreements specify a minimum pump-out frequency based on your kitchen type and grease arrestor size. A small cafe might be required to pump every three months. A high-volume restaurant or commercial caterer might need monthly service.

The standard measure used by most Australian water authorities is the one-quarter rule: the accumulated grease and solids in your trap should not exceed 25 percent of the trap's wet volume between services. If your kitchen output means the trap fills faster, your required frequency goes up, and it's your responsibility to know that, not the water authority's job to tell you.

A licensed trade waste contractor will assess this when they service your trap. If they tell you the trap is consistently at or above capacity between visits, that's a sign your current schedule is too infrequent, either because your kitchen volume has grown or because the original frequency was set without adequate site assessment.

What Counts as an Approved Service

Not every contractor is approved to carry out trade waste work. Most water authorities require contractors to hold a specific accreditation or licence, and they must use approved waste transport vehicles and disposal facilities. The waste itself is classified as liquid trade waste, and its disposal is regulated separately from general waste.

When you book a service, ask the contractor for their trade waste contractor number and confirm they will provide a pump-out record and a waste disposal receipt. These documents are what you show an inspector. A verbal assurance that the job was done is not sufficient evidence.

Record-Keeping: The Part Most Operators Get Wrong

FOG compliance is partly a paperwork problem. Your water authority can require you to produce service records going back two to three years. If you can't, you're non-compliant, even if your trap is physically clean.

A compliant record for each service should include:

• Date of service
• Name and licence number of the contractor
• Volume of waste removed
• Disposal facility used and the relevant waste transport certificate
• Any observations about the condition of the trap (damage, unusual solids, signs of misuse)

The simplest system is a physical folder near the trap, updated after every service. Digital records work equally well. What matters is that they exist and that you can find them when you need them.

Australia's Environment Protection Authority in New South Wales and equivalent bodies in other states publish guidance on what constitutes adequate documentation for trade waste compliance.

Notifying Your Authority When Things Change

If you renovate your kitchen, add cooking equipment, or significantly increase your trading volume, your existing trade waste agreement may no longer be valid for the new discharge load. Most agreements include a clause requiring you to notify your water authority before making changes that affect your discharge.

This is not a technicality. Water authorities audit trade waste agreements, and a kitchen operating under-sized equipment relative to its actual output is a common finding. The cost of upgrading a grease arrestor or interceptor at short notice, particularly during a compliance notice, is significantly higher than planning it as part of a renovation.

Penalties for Non-Compliance

The consequences of FOG non-compliance range from penalty notices to prosecution under state environmental legislation. Under New South Wales's *Protection of the Environment Operations Act 1997*, discharging trade waste in breach of an agreement can attract substantial fines. Similar provisions exist under Queensland's *Environmental Protection Act 1994* and Victoria's *Environment Protection Act 2017*.

Beyond fines, water authorities can require you to upgrade your equipment, increase your pump-out frequency at your cost, or in serious cases, disconnect your trade waste approval, which means your kitchen cannot legally operate.

The EPA Victoria publishes guidance on trade waste enforcement in that state. Industry bodies including the Restaurant and Catering Industry Association also publish member guidance on compliance obligations, though the specific requirements always come down to your individual trade waste agreement.

How to Check Whether Your Kitchen Is Currently Compliant

Start with three questions:

1. Do you have a current trade waste agreement with your water authority, and do you know what it requires? 2. Are you servicing your grease trap at the frequency specified in that agreement, using an accredited contractor? 3. Do you have records for every service going back at least two years?

If the answer to any of these is no or you're not sure, that's where to start. Contact your water authority to request a copy of your agreement if you don't have one. Book a service with a licensed contractor if you're overdue. Set up a record-keeping system before the next service so you have the paperwork from that point forward.
