Three Reasons Why Your Restaurant Needs a Grease Trap

Home Blog 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.
