Grease Traps

Mascot Engineering are Australia’s leading manufacturer of grease traps.

Mascot’s range of approved grease traps are made using Glass Reinforced Concrete (GRC) technology. GRC is incredibly strong due to the presence of reinforcement throughout the material. This type of reinforcement allows for optimal strength to be achieved in a smaller section, making GRC products not only strong and resilient, but much lighter in weight than traditional steel reinforced concrete solutions. Mascot’s manufacturing methods produce grease traps that exceed the required strength without being brittle, so they are not at risk of shattering during delivery or installation as is sometimes seen with polymer based or plastic grease traps.

GRC Grease Trap

What is a grease trap?

Grease Traps, Grease Interceptors, Grease Arrestors… regardless of what you call them, Grease trap devices are designed to remove Fats, Oil and Grease (FOG) from waste water prior to it being discharged to the main sewer system. All grease traps must be approved or authorised by the relevant water authorities to be eligible for installation. It is a requirement to install grease traps for any business that discharges water containing FOGs to the sewer line such as restaurants and take away food outlets.

Choosing the right tank

Generally a Hydraulic Engineer in association with the local water authority or council will assess your proposed use and recommend the appropriate pre-treatment device, or grease trap and the size required. Mascot Engineering have the largest range of authorised trade waste pre-treatment devices in Australia, so regardless of the product and size, we’re sure to have one to suit. Mascot Engineering can also provide custom units with PVC, Cast Iron or HDPE pipes in various sizes.

Installing a grease trap

The great benefit in choosing a Mascot grease trap is that they are easy to install, whilst remaining strong. Their light weight nature makes them simpler to work with on site, and more cost effective to deliver. GRC products have been tested to be of equal strength to a comparable traditional steel reinforced concrete product, but only around a fraction of the weight. For example, our GA100 (1000L) tank can fit through a standard doorway, and only weighs 324kg, in comparison to its concrete equivalent, which weighs over 2.5 tonne.  As Mascot’s grease traps are made from GRC, they do not require a support frame to be constructed during installation. Mascot GRC grease traps come complete with simple and thorough installation instructions and are strong enough to withstand the installation process without the risk of shattering or cracking.

Grease Trap installation


The simple, yet effective design of a grease trap enables FOGs to be separated from waste water and pushed to the top of the device. Grease traps are maintained by specialist cleaning companies who remove or “pump out” the waste, as well as clean the interior of the tank. The frequency of cleaning is determined by the size of your grease trap, the type of business, as well as the volume of water passing through the device. Mascot grease traps are supplied lined with an epoxy resin coating, protecting the grease trap from acid attack and enabling easier cleaning.
