Fibreglass Grease Trap (Arrestors) & Grease Interceptors – Custom Solutions Sydney
If you run a commercial kitchen, café, food manufacturing facility, or any business that processes food, a grease arrestor (also known as a grease interceptor) is one of the most important installations you'll need.
These units prevent fats, oils, grease (known as FOG), and food solids from entering the sewer system, protecting your pipes and the environment.
At Fiberglass Sydney, we design and manufacture high-performance fibreglass grease arrestors and grease interceptors, tailored to your business needs. Whether you need a compact under-sink unit or a large in-ground system, we can build it for you—custom sizes, custom fittings, and custom solutions.
What Is a Grease Arrestor (Grease Trap) or Grease Interceptor?
A grease arrestor (also called a grease interceptor) is a plumbing device designed to capture and separate fats, oils, and grease from wastewater before it flows into the sewer.
What’s the difference between a Grease Arrestor and a Grease Interceptor?
They are essentially the same product, with “interceptor” more commonly used in the USA and “arrestor” or “grease trap” in Australia. In Sydney and across NSW, “Grease Arrestor” is the preferred term used by Sydney Water and local councils.
These systems are legally required in all commercial kitchens and food outlets to prevent pollution, pipe blockages, and fines.
Why You Need a Grease Arrestor or Grease Interceptor
Wastewater from commercial kitchens carries a lot more than water—it’s loaded with:
Without a grease arrestor or interceptor, this material flows into the sewer and solidifies over time, leading to:

Types of Grease Arrestors & Grease Interceptors We Offer
At Fiberglass Sydney, we understand every kitchen or facility is different. That’s why we offer a wide variety of grease traps and arrestors:
How Do Grease Arrestors / Grease Interceptors Work?
Grease arrestors work using gravity separation. When wastewater enters the trap:
- Fats, oils, and grease float to the surface
- Solids sink to the bottom
- Clean water exits through an outlet at mid-level
The trap holds the grease until a waste contractor pumps it out—usually every 1–3 months depending on usage.
Our design includes baffles, access lids, and cleanout ports for maximum performance and easy servicing.
