One crucial aspect of maintaining a clean and efficient kitchen is managing the grease trap. A properly maintained grease trap plays a significant role in preventing blockages, sewage backups, and potential fines. In this blog post, we will discuss what restaurant owners should know about their grease trap and how to maintain it effectively.

1. Understanding the Purpose of a Grease Trap

A grease trap, also known as a grease interceptor, is a plumbing device designed to trap FOG (fats, oils, and grease) from the wastewater generated in your restaurant’s kitchen. It prevents FOG from flowing into the public sewer system, where it can solidify and cause blockages. The grease trap functions by allowing wastewater to flow through while trapping the FOG, which rises to the surface and is held in the trap. The remaining wastewater, free from FOG, exits the trap and flows into the sewer system.

2. Sizing Your Grease Trap

It is important to ensure that your grease trap is properly sized for your restaurant’s needs. The size of the grease trap depends on factors such as the kitchen’s square footage, the number of sinks and appliances that produce FOG, and the average daily flow rate. Having an oversized or undersized trap can lead to inefficiencies and potential issues. Consult a professional plumber or grease trap specialist to determine the appropriate size for your establishment.

3. Regular Maintenance is Crucial

Maintaining a regular maintenance schedule for your grease trap is essential to prevent it from becoming overwhelmed with FOG and causing blockages or odors. Schedule regular pumping and cleaning of your grease trap. The frequency of maintenance will depend on the size of your establishment, the volume of FOG produced, and local regulations. Maintaining records of pump-outs and cleanings is important for demonstrating compliance with regulations.

4. Training Staff on Proper FOG Disposal

Educating your kitchen staff on the proper disposal of FOG is essential in preventing grease trap issues. Train your staff to avoid pouring FOG down drains and dispose of it in designated containers instead. Encourage the use of strainers and grease collection devices in sinks and drains to capture excess FOG. Regularly remind and reinforce the importance of proper FOG disposal with your staff.

5. Monitoring and Troubleshooting

Regularly monitor your grease trap for signs of problems. If you notice slow drainage in sinks, foul odors, or an increase in grease trap pump-outs, it may indicate an issue. Have a protocol in place to address such problems promptly. Contact a professional plumber or grease trap specialist to assess the situation and recommend appropriate actions.

6. Compliance with Local Regulations

Ensure that you are well-versed in local regulations regarding grease trap maintenance for restaurants. Different municipalities may have specific guidelines on grease trap sizing, maintenance schedules, and record-keeping requirements. Familiarize yourself with these regulations and stay updated on any changes to ensure compliance. Non-compliance can result in fines, penalties, and potential disruptions to your business.

7. Professional Assistance

While regular maintenance and monitoring can go a long way in ensuring a well-functioning grease trap, seeking professional assistance when necessary is crucial. Hire a professional grease trap service provider to perform regular pump-outs, cleanings, and inspections. They have the expertise and equipment to handle grease trap maintenance efficiently and effectively.


Understanding and properly maintaining your grease trap is essential for restaurant owners. It helps prevent blockages, sewage backups, and potential fines. By understanding the purpose of a grease trap, sizing it appropriately, implementing regular maintenance, training staff on proper FOG disposal, monitoring and troubleshooting, complying with local regulations, and seeking professional assistance, you can ensure that your restaurant operates smoothly and complies with health and safety requirements. Don’t overlook the importance of proper grease trap management – it’s an investment that pays off in the long run.
