How a Grease Trap Keeps You Out of Trouble?

Have you ever wondered what grease traps are for? They are an essential piece of equipment in the food services industry, but many people do not understand why they are used or how they operate. Here is an introduction to grease traps, explaining how they can save you trouble when you opt for regular grease trap cleaning services.

Stop Clogs

Fats, oils, and grease (known as FOG) do not mix with water. When FOG makes its way down the drain, it does not effectively move through the sewer system. Instead, it congeals, forming a layer on the inside of the piping.

FOG tends to stick together, allowing the layer of grease to grow into a blockage. Once this occurs, the water flow will be stopped, which can cause sinks and drains to back up. This is a massive problem in the food services industry, potentially forcing owners to close their kitchens while the blockage is addressed.

While it is possible to hire grease trap cleaning services to remove a clog after it has formed, this is typically more expensive and more challenging than avoiding the blockage in the first place.

How do Grease Traps Work?

Want to avoid grease clogs? Grease traps and grease interceptors are a must. All drains connected to the kitchen must pass through a grease trap before connecting to the sewer.

Grease traps work by first slowing down the flow of water. Rather than allowing water to pass through the pipe in a few seconds, water takes at least 20 minutes to pass through a grease trap. This allows FOG to congeal in the trap and any grit to settle to the bottom of the tank.

Fats, oils, and grease are lighter than water, meaning FOG will accumulate on top of the water in the grease trap. Baffles in the grease trap are used to capture the grease, allowing the water to pass through while the FOG and grit stay inside.

Over time, FOG and grit will build up within the grease traps. If it is allowed to overfill, it can lead to a blockage. Traps must be regularly emptied by grease trap cleaning services to maintain proper function and comply with regulations.

Conform to Local Laws and Regulation

Food services businesses are often mandated to use grease trap cleaning services by regulatory bodies such as public utilities. FOG build-up doesn’t just happen within your piping. It also occurs in the wastewater system. Failing to adhere to these rules could lead to fines and other restrictions on your business.

It is essential to understand that these regulations may apply to your restaurant, even if you do not serve deep-fried food. It is a popular misconception that FOG build-up only occurs in fast food establishments. This is not the case. Almost all cooking involves some amount of fat and oil, so you need to manage FOG responsibly.

Three Reasons Why Your Restaurant Needs a Grease Trap


Restaurants have been using grease traps for a hundred years. This device is essential to operating a restaurant, and the concept is simple. It operates on the basis that animal fat is ten to fifteen percent less dense than water and wont mix. With this concept, the fat will rise on top of the water. When the water and fat enter the trap, it slows the flow of water and the grease is trapped in a system of baffles. Sediments sink to the bottom into a separate trap and the water is then pumped out into the water waste system. You need to have your restaurant grease trap cleaning completed on a regular basis.

Reason one for having your Restaurant grease trap cleaning completed.

To work within city regulations, a restaurant grease trap needs to be cleaned a minimum of every three months. Some busier restaurants should be cleaned more often. These regulations are enforced for compliance and to ensure the safety and health of employees and customers. Failing to have your restaurant grease trap cleaning completed could result in hefty fines.

Reason two for restaurant grease trap cleaning: what is that smell?

Fats, grease, and oil (FOG) separate from the wastewater; however, there are some particles that will remain in the FOG or on the bottom of the trap. Often, these particles are broken down by micro-organisms. During this activity, hydrogen sulphide, and sulphuric gases are emitted. Most commonly, these gases are creating the foul smell. Poor ventilation is another cause of profane smells. If FOG clogs the ventilation and there is no air flow, then the build-up can create a smell. Without proper ventilation, this smell will begin to seep back into the restaurant. The best solution for preventing odors or removing odors is ensuring your restaurant grease trap cleaning is completed on a regular basis, a minimum of once every three months.

Restaurant grease trap cleaning can prevent damage and costly repairs.

There are many ways that a trap can be damaged. One way is when sulphuric acid is emitted from the break-down of particles. This acid can interact with the trap itself and begin to create small holes, preventing the trap from working. Alternatively, some people do not clean their traps properly and instead opt to pour chemicals, such as odor removers, into the tank. These chemicals can corrode the trap, rendering it useless after a period of time.


Restaurant grease trap cleaning needs to be done on a regular basis. Preventing overflow, smells, damage to the grease trap, and hefty fines are just some of the reasons you need to routinely schedule a cleaning. For more information about Restaurant grease trap cleaning, click here.
