Grease trap cleaning: If you are opening (or of course already operate) a cafe, restaurant or business handling a lot of food and cooking, you will almost certainly need to arrange cleaning of your grease trap. A grease trap (also known as a grease interceptor, a grease converter or a grease recovery device) prevents large amounts of grease or solids from entering the wastewater disposal system. A really good overview can be found on Wikipedia.

Grease Trap Cleaning Intro


We previously published an introduction article to get your grease trap service cleaned cheaply and reliably by Waster. In this part of the section or blog, we seek to answer some common questions we hear from customers as there are many common misconceptions. After all, a grease trap is not something any of us want to spend much time thinking about!


How often do I need to have grease trap cleaning done?

Depending on your business type – you may need to have your grease trap serviced between 6 and 2 times a year. The relevant water authorities in your region mandate the frequency. See the info page at Sydney Water (covering metro Sydney) for coverage of this.



The schedule is decided by these authorities so you do not need to shop around for varying info.


If you have a 1500 or say 3000-litre trap, that amount will be collected when the trap is cleaned (i.e., a service will not clean a proportion of the grease trap). The water will be turned off and all the liquid in the trap will be pumped. The bottom and sides will then be scraped down and the water let refill the trap.

With our commercial grease trap cleaning services, when a small customer signs up for regularly scheduled cleaning, we follow the process as below.


  • We will check with the local water authority as to the required cleaning schedule.
  • We will check on access conditions for the grease trap. Grease trap locations can be in a number of commonplaces. The most common location is outside at the back of the business location. However – grease traps can also be located inside buildings – such as in underground car-parks and even in some instances – in the kitchen area.
  • We will then check if keys or padlocks etc are required for access and provide these to the truck driver.
  • On the scheduled service day – the driver will go to the site and perform the commercial grease trap cleaning services. This service will involve opening the grease trap and pumping out all the liquid and grease in the pit. The technician will then scrape down the sides and bottom of the trap – and remove any excess grease.
  • If appropriate, the driver will then scan the barcode or update the relevant water authority that the service has been performed as scheduled.


How is our grease trap price displayed in the online Waste Management shop?

Pricing of the grease trap service is given as a comprehensive collection and disposal price per litre collected (pricing is provided in cents per litre format). Darwin, Northern Territory is the only exception to this with pricing provided on an hourly rate plus cost per litre basis.



For example, current grease trap price per litre as at 19 February 2020 in Sydney metro is $0.20 per litre – all-inclusive rate.


We have a minimum trap size of 1000 litres (i.e., the basic charge is for 1000 litres) to cover the time for stopping etc.


For larger trap sizes (i.e., for 3000 litres and above) we can generally provide better pricing. Please contact us in this regard to discuss your requirements.


Any terms and conditions or small print to this pricing?

The pricing as provided is on a cent per litre basis. Of course, minimum volumes will apply (1000 litres as above). This will only occur if the volumes you require are very small and it would not be commercially viable for a truck to travel to your location.


We will confirm these details with you at time of booking.

Australia grease trap cleaning – how do grease traps actually work?

A grease trap is a simple plumbing device to prevent the city drain lines from becoming blocked up.


As per WikipediaGrease traps have been used since the Victorian days, although Nathaniel Whiting obtained the first patent for a modern-day grease trap in the late 1800s.


They are used to reduce the number of fats, oils and greases (FOGs) that enter the main sewers. Effectively they are boxes within the drain run that flows between the sinks in a kitchen to the sewer system.


They only have kitchen waste water flowing through them and are not served by any other drainage system such as toilets.”


“In the United States, sewers back up annually “an estimated 400,000 times, and municipal sewer overflows on 40,000 occasions”.


As a result…


The EPA has determined that sewer pipe blockages are the leading cause of sewer overflows, and grease is the primary cause of sewer blockages.”


“When the outflow from the kitchen sink enters the grease trap, the solid food particles sink to the bottom while the lighter grease and oil floats to the top.


The relatively grease-free water is then fed into the normal septic system. The food solids at the bottom and floating oil and grease must be periodically removed in a similar manner as with septic tank pumping.”


“Waste from passive grease traps and gravity interceptors is referred to as brown grease. Brown grease is rotted food solids in combination with fats, oils, and grease (FOG).


Brown grease is pumped out of the traps and interceptors by grease pumping trucks. Unlike the collected yellow grease, the majority of brown grease ends up in landfill sites.”


Australia Grease trap cleaning involves having a trusted contractor with a large liquid holding truck come to your facility. The truck pumps the complete contents of the grease trap back into the truck’s tank (i.e., all liquid in the trap or all grease and water).

Emergency Grease Trap Cleaning


Emergency grease trap cleaning: what do you do if your business has an overflowing grease trap or one that smells really bad and you need it pumped out immediately. Even worse, what do you do if it is a Saturday afternoon and your usual service company is not picking up their telephone or replying to your emails?



We were contacted on a Saturday morning recently by a business owner (of a hotel) that was hosting a wedding that afternoon and was in an absolute panic. Their grease trap required an urgent pump out and the first three suppliers they had contacted did not answer their phone or told them the earliest the trap could be cleaned would be later in the week. I am glad to say that Waster was able to help the customer out and organise an emergency grease trap cleaning that afternoon.


What you should know about emergency grease trap cleaning in Australia

  • Emergency grease trap cleaning is much more expensive than a regular grease trap service. This is because trucks have to be rerouted. In some cases, regularly scheduled customers get bumped to the next day as the trucks can not serve everyone.
  • The price differential can be significant. For example, in 2020 in Sydney, a schedule grease trap service could be c.$210+GST for a 1000 litre trap. For emergency service, this could be up to $2000+GST – 10 times the cost.
  • It is best to have your contracted supplier do the service. If you have a valid agreement with a grease trap service company – you should have them do the job. At the end of the day – it is their responsibility – and they should do it for free or at the normal call out charge.
  • There can be extra costs – i.e. if the trap has not been cleaned in a long time and is “rock solid” with grease. This job will take much longer than usual and will cost more.
  • If you can wait a few days – i.e. if it is not impacting your business too much – you can save significant costs.
  • It should be noted that having an overflowing trap could lead to larger issues – such as damage to piping systems etc – both in your business and in the city municipal piping system.
  • If the trap has not been maintained – or is seen to be overflowing by a water authority or EPA agent – you could be liable for fines.
  • Prior to booking in an emergency grease trap cleaning – we are required to take a hold on a credit card (Mastercard or Visa) of $2000.00.
  • If the cost is lower than this – it will be reimbursed etc after service.


Moral of the story – how to avoid an emergency grease trap cleaning

There is a common saying in the medical community that prevention is much better than cure – and we certainly agree with this.

Customers have a huge number of options to choose from covering both take away and dine-in options. When you are running a restaurant, you need to focus on customer service and your menu. The last thing you need to be worrying about is restaurant grease trap cleaning services.

What you need to know in 2o20!

We cover below the things to know when arranging restaurant grease trap cleaning services:


Register your trip with the local water authority: depending on which city you live in – there will be requirements with the local water authority such as Sydney Water, Icon Water etc.


You should contact them and register your trip. They will then set a cleaning frequency based on your business size and the trap size – i.e. how many litres it is such as 1000 litres, 2000 litres etc. You can see a blog here on how often you should have the trap cleaned.


Engage a grease trap cleaning company such as Waster: you can then appoint a grease trap cleaning company to provide the service in line with the frequency set above.


This company will perform a site inspection to see where the grease trap is and then start regular cleaning services.


picture of a restaurant


Keep records of the cleaning: you will be required to keep evidence of the cleaning of the trap – as per the set schedule.


Additionally, in Sydney, the cleaning company will need to scan a barcode every time they perform restaurant grease trap cleaning services. In other states, you will need to keep a copy of the confirmation or invoice.


This section’s conclusion

Arranging services for your restaurant can be pretty straight forward; choose a reputable supplier and acquire services performed inline with the required schedule.


You can then focus on what is important: providing a great customer experience!



Grease Trap Companies


Grease trap companies: whenever we take a booking for a grease trap service from a new customer or enquiry, one of the first questions we usually hear is “how soon can you pump it out?”


People either want to hear nothing about grease trap cleaning company services or have it serviced immediately!


In most states and metro regions, the local water authority will regulate your business and grease trap to stipulate a frequency for pump outs and then monitor that they have occurred in line with this timetable.


Grease trap companies services – what is a scheduled service?

A scheduled grease trap cleaning or pump out service is on a set time scale. The relevant water authority sets it, reflecting the size of the grease trap and also the type of business operated.  Furthermore, most businesses will have a set schedule or quarterly, six-monthly, etc. But, it can also be as frequent as every month. This really depends on the size of the trap and the type of business you operate.


Generally, the larger the trap and the quieter the business (hence producing less food and grease), the less need for grease trap cleaning companies.



best price


Waster offers grease trap company services on a simple pricing model servicing is on a cent per litre basis.


For example, in Sydney, servicing (as at April 2019) is performed at $0.21 per litre plus GST. Minimum volumes of 1000 litres apply for this pricing (contact us if your grease trap volume is smaller than this). There are no additional charges.


If two service personnel are required from the grease trap company (i.e. if the trap is in an underground carpark, etc.), higher prices may apply.


Thus if your business has a 3000-litre grease trap, the total price for a grease trap cleaning service would be $630.00 plus GST i.e. 3000 times $0.21 plus GST. You will find no additional costs involved. If your business is scheduled to have collections 4 times a year (every 13 weeks) the annual cost would thus be $2,520.00 plus GST.


Grease trap companies near me – why do short notice or emergency services cost significantly more?

Emergency grease trap cleaning is significantly more expensive as other customers need to be rescheduled slightly to make room in a busy schedule to perform your service.


If shopping around in an emergency situation for grease trap cleaning services near me  (i.e. if your trap is already overflowing), keep in mind that a company will need to prioritise your site. As a result, they will potentially bump other sites to another day.


Most grease trap companies or contractors run pretty full timetables and schedules for existing customers.



Most grease trap trucks will be fully booked for days or weeks in advance and an emergency pump out particularly if the trap is overflowing etc could take valuable hours from a trucks schedule.


Our advice is to always try to avoid an emergency grease traps service by ensuring your trap is serviced in line with requirements as this will safe you significant money in the long run. Check out our blog on document disposal and how to protect your business.


Always avoid pouring oil or fat down the sink; save money by arranging a cooking oil recycling service for your business.



Conclusion in this part of the section

Avoid a lot of pain and stress. Simply adhere to the set pump out schedule. Most reputable grease trap companies will do a good job. They will ensure you avoid the multiple issues of an overflowing trap.


Better safe than sorry!


Grease Trap Interceptor Sizing


Grease Trap Interceptor Sizing: many restaurants or any other equivalent businesses can certainly find pumping out trash from their traps quite annoying. Thankfully, Sydney Water has introduced some improvements in their processes; it should hopefully speed up the process and remove stress from business owners.


Grease trap interceptor sizing for your business

Grease trap interceptor sizing is also an important decision prior to opening your foodservice business such as a cafe or restaurant.


Too small a grease trap will mean you need to get in cleaned or pumped out very frequently. This can and will interrupt your business. Furthermore, it can cost you a hefty amount!


Waster also charges a minimum call-out fee (i.e., to cover the driver time, etc.). We have serviced traps as small as 60 litres, which is way too small for any commercial kitchen.


Remember that grease traps can smell quite bad in the cleaning process. So, you really do not want to arrange cleaning too frequently.


If the trap is too large for the business requirements, you will absorb additional costs.


In Sydney, standard grease trap interceptor sizing for a cafe restaurant is between 1000 and 2000 litres. This will usually see your trap being cleaned every three or so months.


Waster provides high quality and low-cost grease trap pump-out services across all major metro regions in Australia. This includes Sydney, Melbourne, Brisbane, Perth, Canberra, Adelaide, Newcastle, Gold Coast, Hobart, Darwin, Wollongong and the Central Coast in New South Wales.


Recent improvements in Sydney Grease Traps And Interceptors service process

To arrange Sydney grease interceptor trap service in line with relevant legislation, previously business owners had to file a Change of Transport form with Sydney Water. Due to improvements in Sydney Waters systems, you can now simply contact a provider; they will file your paperwork for you in an online system that is expected to significantly speed up processes.


Under the Wastesafe programme, grease trap services can only be performed by registered companies. In the words of Sydney Water:


“Wastesafe is an electronic tracking system we use to monitor the generation, collection, transport and disposal of grease trap waste”.


“If you have a grease trap, you must select a Wastesafe transporter to clean it (pump it out) at the frequency we set

Your nominated transporter will notify us when you have arranged a service.

Wastesafe authorised transporters adheres to an Industry Code of Practice which was developed in consultation with WCRAThis external link will open in a new window.”

Grease Trap Waste

Let’s face it – why would you know much about grease trap waste when you do not have to? It is for this reason that we have produced an easy to read and free guide to grease trap cleaning for business owners in Australia.


Waster offers a real alternative to small and medium Australian businesses. We provide low cost and reliable waste and recycling services on flexible 30-day agreements. You never need to worry about lock-in contracts or rollover clauses again with our flexible agreements.


Download your guide to grease trap waste and organising your required services

Arranging regular grease interceptor services is one of those necessary evils in life like paying taxes. You need to be in line with your local water authority guidance (such as Sydney Water). We wrote our guide to provide free advice to business owners. This is also for managers who probably have not had much to do with grease trap waste in the past. They might want to avoid making costly mistakes as much as anything else, hence searching for this.


We state here an extract from the document on 4 common grease trap rip-offs:



To some degree, all of us are attracted by low price because we want to work within a budget. But, some grease trap companies use price as the bait for their false and misleading advertising. They offer a cheap price and then steadily increase prices over time. This can hurt you especially if you have signed a multi-year contract.



Most grease trap cleaning is on a per litre basis. However, be careful that there are no additional fees such as transport costs, disposal costs or staff hours.



This should not be too big an issue. In many areas, the service schedule is set by the local water authority. However, if you are required to keep records of servicing, you should confirm with the water authority what the schedule is; the servicing can happen from with 3 months or 6 months, so you have to confirm.



If a grease trap has, say, 1000 litres, the company you engage should pump out 1000 litres (this will be a mixture of water and grease). If the company has been sticking to the schedule, there should be no need for extra litres. Note: if the trap has not been cleaned for a long time, extra litres may be needed when the cleaner needs to add extra water to clean excessive grease.
