What Size Grease Trap is Recommended for a 50-Seat Commercial Kitchen?

Whether you are running a big restaurant or a 50-seat commercial kitchen, it is important to choose the right grease trap size.

Choosing the right grease trap size for a 50-seat commercial kitchen is not just a plumbing decision – it directly impacts compliance, hygiene, kitchen efficiency and long-term operating costs.

What is a Grease Trap or Separator?

A Grease Trap is a plumbing device that captures fats, oils and grease (FOG) from wastewater before it enters the drainage system. It helps prevent pipe blockages, foul odours, and sewer overflows, especially in kitchens and food courts.

Why Does Grease Interceptor Size Matter for a Small Commercial Kitchen?

A grease trap or grease interceptor is a plumbing device that captures fats, oils and grease (FOG) from wastewater before it enters the drainage system. If the unit is undersized-

1. FOG overflows into the sewer lines
2. Foul odours develop in the kitchen
3. Drain blockages become frequent
4. Health inspections may fail
5. Municipal fines or shutdowns can occur

An oversized trap, on the other hand, wastes money, space and cleaning resources. Correct sizing ensures smooth operations and regulatory compliance. 

What is the recommended Grease Trap Size for a 50 Seat Restaurant?

For a commercial kitchen with approximately 50 seats, the most commonly recommended grease trap size falls within –

• 40 to 75 GPM (Gallons Per Minute)
• 750 to 1000 Gallons Capacity (for large external interceptors)

The exact size depends on kitchen layout, equipment and service style. Smaller kitchens with limited cooking may operate efficiently with a 40-50 GPM grease trap, while high-volume or grease-heavy menus often require 60-75 GPM units.

How to Calculate Grease Trap Size for a Restaurant?

Professional plumbers and inspectors use standardized formulas to determine grease trap size. 

• Fixed-Based Calculation Method: It considers the number of sinks, sink dimensions, drainage load and flow rate. 
• Seating Capacity Method: It is a quick estimate. For instance, for a 50-seat commercial kitchen, inspectors usually approve a minimum of 40 GPM, though 50-60 GPM is safer for long-term use. 

What are the factors that influence the grease trap capacity for a 50-seat restaurant?

Not all small commercial kitchens operate the same way. Here are significant factors that affect the sizing. 

• Type of food served – If your restaurant serves greasy-heavy menus like fried foods, burgers, pizzas, then it requires larger traps. 
• Kitchen Equipment- If the commercial kitchen is using more equipment, then there is a higher wastewater flow, requiring larger grease separators.
• Hours of Operation: If your kitchen has long hours of operation, like full-day service and a late-night kitchen, the grease load is increased. 
• Local Plumbing and Health Codes: Many cities mandate minimum grease trap sizes regardless of calculations. Always verify with local authorities.

• If you have installed the grease trap below the recommended size for a 50-seat kitchen, it can result in fines or failed inspections.
