What is a Commercial Grease Trap?
Definition
A commercial grease trap is a plumbing device designed to intercept most greases and solids before they enter a wastewater disposal system. Commonly used in commercial kitchens, a grease trap is essential for trapping fats, oils, and greases (FOG), collectively known as FOG, from cooking and cleaning processes.
Purpose
The primary purpose of a grease trap is to prevent FOG from entering and clogging municipal sewer systems. These substances can solidify and cause significant blockages in sewage pipes, leading to expensive repairs and environmental damage. By capturing these materials, grease traps play a crucial role in maintaining the efficiency of both onsite and public wastewater treatment facilities.
Historical Context
The concept of grease traps has been around since the Victorian era, originally developed to prevent animal fats from clogging sewer systems as cities grew and sanitation needs evolved. Modern grease traps, while more advanced, still function on the same basic principle: using a containment system to separate FOG from water by allowing the grease to float to the top due to its lower density compared to water.
This simple yet effective mechanism has made grease traps an indispensable part of restaurant and food service sanitation, helping facilities comply with local grease management regulations and avoid penalties associated with sewer blockages.
Understanding how does a commercial grease trap work is fundamental for any business involved in food service. Properly maintained grease traps not only support compliance with health and environmental regulations but also contribute to the operational efficiency and sustainability of the business.
How Does a Commercial Grease Trap Work?
Understanding how does a commercial grease trap work is crucial for maintaining an efficient kitchen and complying with environmental regulations. Let’s break down the functionality, the separation process, and how these systems manage fats, oils, and greases (FOG).
In this context, it’s important to compare automatic grease traps and manual grease traps. Automatic grease traps are praised for their efficiency, sustainability, and cost-effectiveness over a three-year period compared to manual grease traps. Manual grease traps, on the other hand, are traditional systems that are often used in smaller establishments due to their lower initial investment cost and the availability of various sizes.
Additionally, when discussing gravity grease traps, it’s essential to mention grease interceptors as a critical type of grease management system. Grease interceptors are designed to prevent fats, oils, and grease from entering the drainage system by providing technical considerations for sizing and functionality, highlighting their importance in commercial kitchens.
Functionality
A commercial grease trap is designed to intercept greases and solids before they enter the wastewater disposal system. This is vital because these substances can solidify and clog pipes, leading to expensive repairs and environmental damage.
Separation Process
When wastewater enters the grease trap, it goes through a cooling process that helps separate the grease from the water. Grease, being lighter than water, floats to the top. The trap contains this grease while allowing the cleaner water to flow out towards the sewage system.
FOG Management
Proper FOG management within a grease trap involves routine cleaning and maintenance to ensure that the accumulated grease doesn’t overflow or escape into the sewage system. This process is essential to prevent blockages and maintain the efficiency of the wastewater treatment.
Types of Commercial and Automatic Grease Traps
There are several types of grease traps that cater to different needs:
- Passive Grease Traps: These are compact and usually installed indoors, under sinks or near dishwashers. They use natural water flow to separate grease from water.
- Automatic Grease Removal Units (AGRU): These systems automatically separate and remove grease from the water on a set schedule, reducing manual cleaning requirements.
- Gravity Grease Traps: These are large, in-ground tanks that use gravity to separate grease from water. They are suitable for high-volume environments and require periodic pumping.
Components of a Grease Trap
To understand the inner workings, here are the key components of a grease trap:
- Flow rate controller: This part regulates the speed at which wastewater enters the trap, ensuring efficient separation.
- Inlet pipe: Wastewater from the kitchen flows into the grease trap through this pipe.
- Baffles: These are barriers within the trap that slow down the flow of wastewater, allowing grease to rise to the surface and solids to settle at the bottom.
- Water: The addition of water helps to cool down the wastewater, which assists in the separation process.
- Outlet pipe: After the grease is separated and contained, the cleaner water exits the grease trap through this pipe and moves on to the sewer system.
Each component plays a crucial role in ensuring that the grease trap functions properly and efficiently. Regular maintenance and understanding the operation of these components are essential for preventing clogs and ensuring that your kitchen runs smoothly.
We’ll look into the best practices for installing and maintaining these systems to maximize their efficiency and lifespan. This includes choosing the right location for installation and understanding the frequency and methods of cleaning required to keep your system in top condition.
Installation and Placement of Commercial Grease Traps
Choosing the right location for the installation of a commercial grease trap is critical for its efficiency and ease of maintenance. Here we’ll explore the best practices for placement, whether it’s under the sink, in-floor, or outdoors. It’s essential to ensure the grease trap is properly connected to the kitchen’s drain or waste pipe, as this connection is crucial for intercepting FOG (fats, oils, and greases) and containing food waste, thereby enhancing the functionality of the sewer system.
Location Guidelines
When deciding where to install a grease trap, consider accessibility for cleaning and maintenance, the proximity to kitchen waste sources, and compliance with local regulations. The installation spot should allow for easy access to the trap for regular inspections and pumping without disrupting kitchen operations.
Under Sink Installation
Under sink grease traps are common in smaller kitchens or where space is limited. These traps are compact and connect directly to the plumbing from sinks and dishwashers. When installing under the sink, ensure there is enough room to remove and service the trap. This placement is ideal for low to moderate grease volumes.
In-Floor Installation
For larger kitchens with higher volumes of grease, an in-floor installation might be more appropriate. These units are installed below the kitchen floor, offering larger capacity and less frequent cleaning cycles compared to under sink models. In-floor grease traps require careful planning to ensure they do not interfere with kitchen operations or pose a safety hazard.
Outdoor Placement
Outdoor installations are suitable for very large grease traps or interceptors. These are typically used by high-volume food establishments and are buried underground. The key advantage is their large capacity, which minimizes the frequency of cleanings. However, they must be protected against extreme weather conditions and should be easily accessible for maintenance vehicles.
Considerations for All Installations
Regardless of the installation type, there are several factors to keep in mind:
- Proximity to Food Waste Sources: The closer the grease trap is to the source of the grease, the more effective it will be.
- Compliance with Health and Safety Standards: Ensure that the installation complies with local health and safety regulations to avoid penalties.
- Ease of Access: Regular maintenance is crucial, so install the grease trap in a location where service personnel can easily access it.
By following these guidelines, you can ensure that your grease trap is not only effective at trapping fats, oils, and grease but also convenient to maintain and compliant with local regulations. Proper installation is the first step toward a hassle-free grease management system in any commercial kitchen.
Maintenance and Cleaning of Commercial Grease Traps
Maintaining and cleaning commercial grease traps, especially the restaurant grease trap, is essential to prevent clogs, odors, and potential backups that could affect your business operations.
The restaurant grease trap plays a pivotal role in preventing FOG (fats, oils, and grease), sugar, and other solids from entering the sewer system. Ensuring you have a functioning grease trap is crucial to prevent clogs and ensure efficiency in managing restaurant grease and complying with FOG regulations. Regular professional cleaning based on the grease trap’s size, flow, and use is important to maintain its efficiency and comply with city ordinances.
Here’s what you need to know to keep your grease trap functioning efficiently.
Additionally, it’s important to properly dispose of cooking oil to prevent damage to the grease trap and plumbing systems, which helps in preventing sanitary sewer overflows and managing restaurant grease effectively.

Frequently Asked Questions about Commercial Grease Traps
How often should a grease trap be cleaned?
The frequency of cleaning a commercial grease trap varies, but a good rule of thumb is every 1 to 3 months. This guideline helps prevent the buildup of fats, oils, and greases (FOG), which can lead to clogs and inefficiencies. Specifically, it’s recommended to clean the trap when it’s about 25% full of FOG to maintain optimal functionality.
What is the 25% rule for grease traps?
The 25% rule is a maintenance guideline suggesting that a grease trap should be cleaned when FOG and solid waste occupy approximately one-quarter of the grease trap’s capacity. This rule is crucial because once FOG exceeds this limit, the efficiency of the grease trap decreases, and the risk of fats, oils, and greases escaping into the sewer system increases. Regular monitoring and adherence to this rule can help avoid costly fines and plumbing issues.
Can a grease trap handle all kitchen waste?
No, a grease trap is not designed to handle all types of kitchen waste. Its primary function is to intercept and trap FOG before these substances enter the wastewater system. Solid food particles, debris, and non-biodegradable materials should not be sent down the drain as they can cause clogs and damage the grease trap.
