Effective precast grease interceptor solutions for preventing blockages and maintaining sanitary public water systems.
Why should you incorporate precast grease interceptors in your next project?
Every restaurant, senior living center, daycare, or food production facility that uses grease must handle the problem of how to prevent it from entering the public water system. In fact, many municipalities require the use of some system to effectively eliminate fats, oils, and grease (FOG) from clogging public sewers and generating unsanitary wastewater backups.
Establishments should first trap as much of this FOG waste as possible in order to recycle or dispose of it through local licensed renderers or waste removal organizations. Any FOGs that are not caught in this process can be collected by large concrete grease interceptors, which are often located under the kitchen and separate the grease from the moving wastewater. The collected FOGs must periodically be removed from the grease interceptor in order to continue to function properly.
The advantage of using precast grease interceptors is that implementation is fairly simple. In contrast to poured in place structures, precast installation can be completed with simple machinery and a small group of professionals.
What to look for in a precast grease interceptor supplier.
A track record of implementing strong, corrosion-resistant material that outlasts exposure to FOGs.
Size and design variations that effectively handle volume and flow considerations while affording easy maintenance.
High-quality concrete options that measure up to traffic-rated loading if located under roadways.
Materials that are locally sourced and environmentally responsible.
Precast Grease Interceptor Designs
The Baffle System is a very basic design which dates back to the 1800s, and is still in use today due to its effectiveness. If the flow of water is slow enough, this design allows the FOG to naturally separate and rise to the top as sediment sinks to the bottom of the first and middle chambers. Another baffle then stops the FOG from traveling any further in the system as the water flows through the second chamber and exits the precast grease interceptor.
Stand Pipe System
The Stand Pipe System utilizes a crossover pipe to convey water from the first chamber into the second chamber. This design slows the flow, affording extra time for the FOG to separate from the water as it flows through the precast grease interceptor. The pipes are often removable, and are reachable from the access covers to facilitate regular cleaning.

This article highlights the importance of finding a fabrication that can withstand acidic pH levels, which are bound to occur in most grease interceptor applications. This article suggests that plastic is the answer; do you agree? We find the cons of plastic to outweigh the pros. Better to find a precast supplier with high standards of quality.
Nice article about precast concrete grease interceptors, by Building Safety Journal. “The U.S. Environmental Protection Agency (EPA) estimates that there are more than 40,000 sanitary sewer overflows each year, the majority caused by grease buildup. Maintaining these sewers is costly — more than $25 billion per year — a situation often exacerbated by attendant cleanup fines levied by the EPA or the authority having jurisdiction.”
