A Better Grease Trap

Traditional concrete grease interceptors may be the first choice that comes to mind when you think of grease traps, but they are not the best choice. They corrode after just a few years, are not very efficient and don’t provide much installation flexibility.

Trapzilla systems solve these problems, providing as much grease trap capacity as you need with flexible installation configurations and a longer operational life. 


Traditional grease traps are constructed of concrete and metal. While these may seem durable materials, fats, oil and grease take a toll on them over time. Traditional traps will corrode and often begin to fail after five to eight years. The only solution is to replace them.

Trapzilla Compact Supercapacity Grease Interceptors are constructed of durable, molded polyethylene, which is much more resistant to corrosion. This allows them to operate efficiently for many years without requiring expensive replacements.


Traditional concrete traps must be emptied once they reach about 25 percent of their volume. Beyond 25 percent they lose significant efficiency. That means that excess oils and fat will end up the sanitary sewer system — putting your facility out of compliance, raising the risk of costly blockages and creating the potential for fines.

It also means they must be built significantly larger than the volume of grease they actually handle.

Trapzilla interceptors, though, retain the same high level of efficiency as they fill with waste grease. Depending on the size, they can accumulate more than 90 percent of their volume in waste grease.

The TZ-600, the largest Trapzilla, can accumulate more than 600 pounds of waste grease before it must be emptied. And because most of that volume is grease, when you pay a pump truck to empty it you’re paying mostly for actual grease disposal, rather than grease and a lot of water.

Installation flexibility

Trapzilla units come with a wide variety of installation options. They can be installed:

  • Buried outside in the ground.
  • On the floor of a basement or other suitable space.
  • Between floors in space used for utility and mechanical systems.

Individual Trapzillas can handle from 35 gallons per minute (4.73 l/s) to 150 gallons per minute (9.46 l/s), depending on the size of unit needed. But multiple Trapzillas can also be plumbed in parallel to handle extremely high flows from very large food service establishments.

Whether you want a small unit for a single modest kitchen or need a system that can serve a large hotel or resort, Trapzilla has options that provide the capacity and flexibility you need.

Solids separation capabilities

In addition to trapping grease, Trapzilla Solids Separators are also available that will trap solids, such as rice, coleslaw and other food waste, keeping it out of the sewer system and keeping your kitchen in compliance.

Trapzilla Solids Separators are engineered with the same durability and installation flexibility as the grease traps.
