Grease Trap Cleaning & Waste Disposal

Restaurants, large kitchens and other businesses in the food industry produce a lot of grease and food solids waste. A grease trap, also known as a grease interceptor, is a plumbing fixture that is specifically designed to capture grease and prohibit it from passing into the sewage system. 

It’s an essential piece of equipment in restaurants and schools and is required by health inspectors for large establishments. 

In Western Australia, the Water Corporation has regulatory oversight of grease trap installation and maintenance. In order to comply with local regulations and ensure optimal functionality, the Water Corporation requires all businesses that have a grease trap installed on-site have it serviced on a regular basis. 

As one of Perth's most reliable liquid waste disposal specialists, Tunnel Vision conducts a safe, efficient, discreet and environmentally friendly grease trap cleaning service.

What is a Grease Trap? 

A grease trap is a water-containing concrete, steel or fibreglass box with an inlet pipe and a raised outlet.

As wastewater passes into the grease trap, the flow rate is slowed. This allows food particles to sink to the bottom of the trap, while oil and grease rise to the surface. Baffles set inside the box allow water to flow underneath, but provide one or more solid walls as an additional barrier to FOG waste.  

Many modern grease traps also feature additional filters or strainers to trap larger pieces of food waste or solid fats before they even enter the trap. Tunnel Vision includes a grease trap filter cleaning and assessment as part of our service. 


How Does a Grease Trap Work? 

Grease traps are small reservoirs built into wastewater piping close to grease producing sources.

The reservoir retains the wastewater long enough for the grease to solidify on the surface. Once the oils and greases are separated from the wastewater, they can then be removed and disposed of properly by a liquid waste disposal specialist. 

When greasy water goes down a drain, it is fed through a pipe into the grease trap. First, the grease trap works by cooling down the greasy water.

The grease trap has the ability to use water to separate the different layers of fats, oils and grease (FOG) waste within. The greasy water is given the chance to settle, allowing fat, oil and grease to float to the surface of the grease trap and become trapped.

The water then flows into another compartment where it settles for a second time to further separate grease and food particles. The somewhat cleaner wastewater then flows directly into the sewer system. 

The oil and grease collected by grease traps must be removed regularly to ensure optimal performance and safety. It is recommended that a grease trap should be emptied when the sludge level reaches ¼ of the level of the tank. Irregular grease trap disposal maintenance and cleaning can cause fat deposits to accumulate, either settling along the inside of the pipe wall or coming loose and causing blockages and corrosion further down the line.  

For small grease traps (e.g. those installed under individual sinks), the grease trap waste can be removed manually by scooping it into watertight containers and disposed of with other household garbage.  For large grease traps, such as those used in commercial kitchens and food processing factories, contract a grease trap cleaning and pumping company such as Tunnel Vision on a regular basis or the local water authorities will intervene.

Tunnel Vision’s grease trap servicing prevents wastewater system blockages and saves you from unnecessary plumbing costs. 

We can provide a single or regular grease trap service where we will contact you to arrange an appointment according to your selected maintenance schedule. We do this via an automated system that keeps track of your grease trap cleaning and maintenance program. 

The process for our grease trap cleaning service requires a vacuum liquid waste truck. Our professional drivers will remove your grease trap’s cover and using a hose will pump all the liquid waste into the truck. 

Once the grease trap is cleaned and washed with a low-pressure washer the cover is replaced and the site left neat and tidy.

Finally, your liquid waste disposal expert will complete all WA Water Corporation and EPA required documentation. All FOG (fat, oil and grease) waste is then recycled.

What Are Western Australia's Grease Trap Regulations? 

There are local and international regulations that control both above-ground and below-ground grease traps. 

In order to determine how often you are required to clean your grease trap, you should refer to WA’s Water Corporation's guidance for trade waste

Based upon the size of your grease trap, you are required to clean it quarterly or monthly. With that being said, your grease trap may require cleaning earlier than this if it is showing signs that it needs cleaning.

Contracting and establishing a maintenance schedule with your commercial plumber will help keep your drainage systems in good shape.

Frequently Asked Questions

What Are the Signs That a Grease Trap Needs to Be Cleaned?

To begin, if you notice that you have smelly drains, that is a big indicator that your grease trap needs to be cleaned.

Secondly, if you turn off the faucet and your drain gurgles or growls as it drains, this is another indicator.

Lastly, if your sink is draining very slowly and has a hard time keeping up, your grease trap may be full. 

How Often Does a Grease Trap Need to Be Cleaned?

How regularly a grease trap is maintained depends on the business type, waste levels, waste sorting techniques, and the size, type and age of the grease trap. 

A grease trap should be cleaned when it gets to 25% capacity. When levels exceed this amount, the trap becomes less effective and higher levels of FOG enter the main wastewater plumbing system.

Leaving your grease trap above 25% capacity for prolonged periods has the potential to result in emergency plumbing repairs. If you find that the grease trap fills up within 30 days, it may be time to look to install a larger grease trap to fulfil your needs.  

How to Maintain a Grease Trap?

In between cleaning, kitchen employees must follow best practices in order to provide preventative maintenance for their grease traps.

The first thing they must do is to be sure to scrape all plates and dishes with a rubber spatula into the rubbish bin before washing them in a sink. This helps to prevent an excess of fats, oils and grease from going down the drain.

Secondly, it is important to install screens under the pre-rinse sink and the three-compartment sink. These will filter any food or grease leftover on the plates which will help keep the pipes protected.

If grease is spilled on the flow, it must not be mopped into the floor drains. Instead, grease or greasy foods should be cleaned up with towels and thrown into the bin, instead of dumping grease into an under-sink grease trap. 

Who Needs Grease Trap Disposal Services?

Major industries that generate large quantities of grease are food packagers, commercial kitchen, restaurants, cafeterias, and hospitals, as well as individual homes or strata buildings.  

Domestic grease traps might not have the scope of commercial and industrial businesses, but residential grease interceptors also require maintenance.  

Household FOG (fat, oil and grease) waste is the number one cause of residential drain blockages.

Large office complexes and strata apartment blocks are also particularly susceptible to grease trap overflow into shared wastewater networks, where a Tunnel Vision automated grease trap service can provide the perfect solution and complete peace of mind. 

What Are the Benefits of Grease Traps?

From an environmental perspective, the benefits of using grease traps to collect and recycle grease are two-fold.  

First, the liquid waste that is cleaned out of the grease traps doesn’t end up in our ocean. Grease traps and grease trap pumping reduces the amount of nutrient-rich runoff into our oceans and water catchment areas.  

Secondly, when it is brought to a specialised treatment plant to be decomposed and converted into mulch, it is servicing an extremely important role in the agricultural industry.

Agriculture is extremely demanding on the soil since growing food requires plants to take nutrients out of the soil in order to produce what we eat. Unless we replace these nutrients in the form of mulch or fertilisers, plants won’t be able to grow effectively.

There are several key economic and environmental benefits to using grease traps.

The main economic benefit is that sewers will require fewer maintenance and repairs when grease traps are used.

Since warm grease will cool once inside the sewer system, it can build up, create blocked drains, and cause sewage backups and flooding to businesses, surrounding areas and local rivers. Therefore, it’s extremely economically beneficial to use a grease trap and to service it properly and regularly. 

What is the Process of Recycling Grease Waste?

Once the grease waste has been pumped into the truck it is then brought to a processing and treatment plant.

We at Tunnel Vision have partnered with various specialists to treat the liquid waste that was removed from grease traps in Perth and surrounding areas.  

The liquid waste is placed in large concrete pits where any remaining water may evaporate. Sawdust is added and mixed into the greasy rubbish, followed by wood chips and peat moss. The mixture is given time for micro-organisms to break down the grease and food particles.

Once this process of decomposition is complete, the remaining product is garden mulch which is subsequently used to help grow more food, bringing the cycle full circle.
