Grease Trap Servicing Before an Inspection: What to Have Ready When the Inspector Walks In

This guide is for owners and managers of commercial kitchens in Australia who know an inspection is coming, or suspect one is, and have not checked the trap in a while. By the end you will know when to book the service, what to put in the folder, and whether a clean the day before helps you or hurts you.

Why the inspection date should set your booking date

Most operators only think about the trap when it smells, backs up, or a council or Sydney Water inspection is due. The first two arrive without warning and cost you a bad night. The third is the only one you can see coming, so it is the best one to plan around.

An inspection does not test whether the trap is clean on one afternoon. It checks whether you run the trap the way your approvals say you should. The paperwork, the service history and the condition of the device all count. A spotless trap with no records raises more questions than a trap a few weeks into its cycle with a tidy log.

If you want the legal background first, read Grease Trap Regulations in Australia: What You Need to Know. This article sticks to the practical side: what to do in the weeks before someone knocks on the door.

What an inspector looks for

Inspections differ by council, water authority and state, so treat this as a working list and not a promise. Your own approval documents and your local authority decide what applies to you. In Sydney, the water authority publishes trade wastewater information for businesses on the Sydney Water website. Your state environment regulator, such as the NSW EPA, explains the wider waste rules.

The paperwork

Expect a request for some or all of these:

• Your trade waste agreement or approval, including the service frequency it sets.
• Service dockets from your licensed cleaner, with dates, trap location and volumes removed.
• Proof that the waste went to a licensed facility.
• Any notes on faults, repairs or access problems since the last visit.

Your trade waste agreement with the water authority sets the pump-out frequency for your kitchen. Many operators do not know theirs. If that is you, find the agreement before you do anything else. Every other decision in this article depends on it.

The trap itself

Expect the inspector to lift the lid, so the lid has to lift. Heavy stock crates, a walk-in compressor or a locked cupboard over the access point will be noted. The inspector checks whether the trap matches the type your paperwork names, whether the baffles and lids are intact, and whether the contents look like normal build-up or neglect.

The question nobody answers: should you clean it the day before?

Most kitchens panic and book a clean for the day before the visit. It feels safe, but it has two problems.

First, a trap emptied yesterday shows nothing about how you run it. If your records show a six-month gap between cleans and your agreement asks for more often, a fresh trap does not erase that gap. The dockets still tell the story.

Second, a last-minute booking costs more and gives you less choice of cleaner. The page on booking cold explains why. The same logic applies when the deadline is an inspector and not a smell.

The better rule is simple. Book the service so the docket lands inside the interval your agreement sets, with enough time before the inspection to fix anything the cleaner finds. A clean three weeks out leaves you room. A clean the night before leaves you none.

Work backwards from the inspection date

Your options depend on how much notice you have. Here is how each timeframe plays out.

• Four or more weeks out. You have time to find your agreement, compare quotes and book a regular slot. This is the cheapest and calmest path, and it puts a fresh docket in the folder well before the visit.
• One to three weeks out. You still have choice, but book now. Ask for the earliest slot that falls on a quiet trading day. Ask the cleaner to flag any damaged lids or baffles so you can repair them before the visit.
• Under a week out. Expect fewer slots and urgency pricing. Prioritise a service if you are overdue under your agreement, and spend the remaining days on access and paperwork.
• Notice-free inspections. Some visits arrive with no warning. Keep the folder up to date as a permanent habit, and book to your agreement's interval, not to a date.

Cleaners quote on trap size, service frequency, access to the trap and disposal fees. Two kitchens with the same trap can get quite different prices. You control two of those factors: clear access and a known schedule. Both lower the quote.

A worked example

Take a pub with a bistro. It has one underfloor trap and an agreement that sets pump-out at a regular interval. On a Monday, the manager learns an inspection is due in about a fortnight. The last docket in the folder is dated near the end of that interval, so the pub is close to overdue.

The manager has three choices.

1. Wait and clean the day before. The trap looks fine, but the new docket lands almost a full interval after the last one. An inspector reads that as a late service. 2. Book this week. The docket lands early in the fortnight. The cleaner reports a cracked lid seal, and the manager has days to repair it. 3. Do nothing and hope. The trap is near full, the service is overdue and the folder has a gap.

Option two wins. The cost is a visit that lands slightly earlier than the schedule needs. The gain is a clean record, a fixed lid and a trap that handles the weekend trade before the inspector arrives.

The decision rule: if you are in the back half of your interval, book now. If you have just been serviced, spend the time fixing access and records instead.

Build the folder the week before

Once you know where everything is, a good folder takes under an hour to put together. Keep these in one place, on paper or in a shared drive:

1. Your trade waste agreement or approval. 2. Every service docket since you took over or opened. 3. The cleaner's contact details and licence information. 4. A site note with the trap location, type and access instructions. 5. A repair note for anything the cleaner has flagged.

If you took over a site and the history is missing, say so plainly. Record the date you found the gap, book a service, and start the log from there. An honest, recent record beats a guessed one. If you are unsure what approvals you hold, Business.gov.au is a good place to find the ones that apply to your business type.

Prepare the floor, not just the folder

On the morning of the service, clear the way to the trap. Move crates, mats and bins. Tell the cleaner about slippery or cramped access so they bring the right gear. If the trap sits in a shared area, let the landlord or the neighbouring tenant know a truck is coming.

Book the visit outside your busiest service. Cleaners struggle to work around a hot kitchen, and you do not want a hose line across the pass at 7pm on a Friday.

After the inspection

Whatever the outcome, update the folder the same day. Note what the inspector asked for, what they flagged and what you promised to fix. If they set a deadline, put it in the calendar and book the cleaner or plumber straight away.

Then reset your schedule. Passing an inspection does not change the service interval your agreement sets. If your menu, covers or opening hours have grown since you set the schedule, ask your cleaner whether the trap is filling faster than the interval allows.

Get three quotes before the date arrives

The simplest way to take the pressure off is to compare prices early. Grease Trap Quotes sends you three quotes from licensed cleaners by SMS, usually within about a minute of your request. The service covers Sydney today and is expanding to other Australian cities. Requests come from commercial kitchens such as restaurants, cafes, pubs, clubs, takeaways and food courts.
