Grease Trap Cleaning Frequency: What Dubai Municipality Requires
One of the most common questions we get from restaurant owners and kitchen managers in Dubai is: “How often should I clean my grease trap?” The answer depends on your trap size, kitchen volume, and local municipality requirements.
Dubai Municipality Requirements
Dubai Municipality (DM) mandates that all commercial food establishments maintain their grease traps according to these guidelines:
- Small traps (AG1, AG1.5): Every 2-4 weeks for high-volume kitchens, monthly for low-volume
- Medium traps (AG2, AG3): Every 1-2 months depending on FOG (Fats, Oils, and Grease) output
- Large traps (AG4, AG5, B-Type): Every 2-3 months with regular monitoring
- Underground traps (C-Type): Every 3-6 months with quarterly inspections
The 25% Rule
The industry-standard 25% rule states: clean your grease trap when FOG and solids reach 25% of the trap’s total capacity. Beyond this threshold, the trap loses efficiency and grease can pass through to the sewer system, causing blockages and municipality violations.
Signs Your Grease Trap Needs Immediate Cleaning
- Foul odors coming from drains or the trap area
- Slow draining sinks in the kitchen
- Grease overflow visible around the trap lid
- Gurgling sounds from the drainage system
- Failed municipality inspection or warning notice
Cleaning Frequency by Business Type
| Business Type | Recommended Frequency | Why |
|---|---|---|
| Fast food restaurants | Every 2-4 weeks | High frying volume, heavy FOG output |
| Fine dining restaurants | Every 4-6 weeks | Moderate FOG, diverse cooking methods |
| Cafes and bakeries | Every 6-8 weeks | Lower FOG output, less frying |
| Hotels (multiple kitchens) | Every 2-4 weeks per kitchen | High volume, multiple outlets |
| Cloud kitchens | Every 2-3 weeks | Compact traps, intense cooking cycles |
| Catering companies | After major events + monthly | Variable volume, event-driven peaks |
Penalties for Non-Compliance in Dubai
Dubai Municipality takes grease trap compliance seriously. Penalties include:
- First violation: Warning notice with 7-day compliance deadline
- Second violation: Fine of AED 500-5,000
- Repeated violations: Fines up to AED 50,000 and potential business closure
- Sewer contamination: Additional fines from drainage authority
How to Maintain a Cleaning Schedule
The best approach is a preventive maintenance contract with a licensed grease trap cleaning company. At GTC, we provide:
- Scheduled cleaning visits at your required frequency
- Compliance certificates after each service
- Before/after photo documentation
- Maintenance logs for municipality inspections
- 24/7 emergency service if issues arise between scheduled visits
Tips to Extend Time Between Cleanings
- Scrape plates before washing — reduces solid waste entering the trap
- Use strainers on all kitchen sink drains
- Never pour oil directly down the drain — use a waste oil container
- Install a biological dosing system — enzymes break down FOG between cleanings
- Train kitchen staff on proper waste disposal practices
