Choosing the wrong grease trap size is one of the most common compliance mistakes in UAE commercial kitchens. An undersized trap leads to FOG (fats, oils, and grease) overflows, failed municipality inspections, and fines up to AED 50,000. Use our calculator below — based on the official Dubai Municipality GTT (Grease Trap Tester) formula — to find the exact model your kitchen needs.

How the Dubai Municipality GTT Sizing Formula Works
The Dubai Municipality (DM) requires all commercial kitchens to install grease traps sized according to a specific Grease Trap Tester (GTT) methodology. This ensures adequate FOG capture and prevents sewer blockages across the emirate.
• Kitchen Type — Restaurant, hotel, cafeteria, bakery, etc. (determines grease output factor)
• Hours of Operation — 8-hour shifts to 24-hour operations
• Meals Served Per Day — Under 200 to 2,000+
• Faucet Configuration — Number and size of faucets connected to the trap
• Drainage Pipe Size — 2 inches to 7+ inches
Our calculator applies the full DM GTT methodology with two modes: Planning/Construction (8-step detailed analysis for new kitchens) and Built/Operational (3-step quick recommendation for existing kitchens). Both modes provide a specific product recommendation from our DM-approved range.

Why Correct Sizing Matters
- Undersized traps overflow during peak hours, causing FOG to enter the municipal sewer. Dubai Municipality fines range from AED 10,000 to AED 50,000.
- Failed inspections can delay or block your food trade license renewal.
- Sewer blockages can result in cleanup liability exceeding AED 100,000.
