Grease Traps

Durable, High Quality Grease Traps Approved for use in all States and Territories

CV Plastics manufacture grease traps (also known as Triple Interceptors, Baffle Pits, Grease Interceptors, GIT’s, Food Oil Interceptors or FOI’s) in a range of standard sizes, or custom built to your specification. Various designs include ‘Thin Skin’ models, and our unique Heavy Duty ‘Twinwall’ versions for faster installation and commissioning.

Grease traps are used in food service environments like commercial kitchens, cafe’s, restaurants and food manufacturing facilities to trap grease, oil and other contaminants before they cause damage and build up in the waste lines and water treatment facilities.

In the automotive industry including mechanical workshops and car washes grease traps prevent damage to the pipes and the environment. See petrol and oil interceptors.

CV Plastics stock above ground and below ground grease traps, and build semi below ground and custom grease traps to order. They come complete and ready to install.

General Questions

Yes, grease traps can be utilised in residential settings, especially in conjunction with septic systems on rural properties.

They play a vital role in maintaining the optimal condition of your septic tank by effectively capturing grease and preventing it from entering the system.

Installing a grease trap ensures the efficient operation of your septic system, promoting its longevity and minimizing the risk of clogs or backups caused by grease buildup.

To prolong the lifespan of your grease trap, regular maintenance is essential. Keep the trap clean and well-maintained, ensuring that the lids are well lubricated for smooth operation.

It’s crucial to engage a licensed waste removal service to perform periodic pumping out of the grease trap’s contents, however we don’t provide this service.

To get rid of the grease and waste from your grease trap, you need to hire a licensed waste removal expert. They have the skills and tools to handle the waste safely and legally, following environmental rules.

The build-up of fats and oils in your pipes can lead to obstructions and even significant damage.

This can result in costly repairs and potential disruption to your daily operations.

Therefore, it’s crucial to ensure your grease trap is always in good working order to avoid these issues.

Yes, there are often regulations surrounding the installation and maintenance of grease traps, which can vary by location.

To ensure compliance with these rules, we recommend having a qualified plumber handle the installation.

They will be familiar with the local regulations in your area and can ensure that the installation and subsequent maintenance of your grease trap adheres to these guidelines.

There are several advantages to choosing plastic grease traps over those made of other materials. Firstly, plastic grease traps are easier and more cost-effective to clean because grease and fat do not stick to the plastic walls as they do with concrete or fibreglass traps.

Secondly, plastic grease traps are lightweight, which typically eliminates the need for heavy lifting equipment during installation. This can make the installation process quicker and less disruptive.

Lastly, fabricated grease traps, which are often made from plastic, can be easily modified to meet specific customer needs. This means that a plastic grease trap can be customized to fit your particular requirements, offering greater flexibility than moulded grease traps.

Yes, there are special considerations when installing a grease trap in a high-volume kitchen.

One of the most important aspects is the size of the grease trap. The correct sizing should always be confirmed with your local water authority or other relevant governing bodies.

This ensures that the grease trap can handle the high volume of waste produced and comply with local regulations.
