Regular grease trap maintenance in Dubai and across the UAE isn’t optional — it’s a legal requirement enforced by Dubai Municipality, ADAFSA, and every emirate’s food safety authority. Neglected traps overflow, block sewer lines, attract fines up to AED 100,000, and can shut your kitchen down overnight.
GTC provides scheduled maintenance plans starting from AED 199/month with DM-compliant documentation, certified technicians, and coverage across all seven emirates. Call +971 58 570 7110 for a free maintenance assessment.
Why Grease Trap Maintenance Cannot Be Skipped
A grease trap without regular maintenance is a ticking liability:
- DM fines from AED 2,000 to AED 100,000 — Dubai Municipality enforces strict cleaning frequency requirements. A single failed inspection can trigger immediate penalties.
- Kitchen closure orders — inspectors have authority to shut down food establishments that fail grease trap compliance checks, effective immediately.
- Sewer line blockages — accumulated FOG (fats, oils, and grease) hardens in drain pipes, causing backups that flood kitchen floors and contaminate food preparation areas.
- Insurance exclusions — most commercial kitchen policies exclude water damage caused by unmaintained grease management systems.
- Trade licence delays — DM compliance certificates are required for licence renewals. A failed grease trap inspection delays your entire renewal process.
- Pest infestations — overflowing traps create breeding grounds for cockroaches and drain flies, triggering additional food safety violations.
DM Cleaning Frequency Requirements
Dubai Municipality mandates cleaning schedules based on trap size and kitchen output. These are minimum frequencies — high-volume kitchens may need more frequent service.
| Trap Size | Capacity | DM Minimum Frequency | Recommended for High-Volume |
|---|---|---|---|
| Small (AG1–AG2) | 15–25 USG | 4 times per month | Weekly |
| Medium (AG3–AG4) | 40–100 USG | 2 times per month | Weekly |
| Large (AG5) | 135 USG | 2 times per month | Bi-weekly |
| Underground (B/C Type) | 500–5,000L | Monthly | Bi-weekly |
Critical rule: DM guidelines state that traps must be cleaned when the grease layer reaches 25% of the total trap depth. For small traps in busy kitchens, this can happen in under a week.
What Professional Maintenance Includes
Our maintenance service goes far beyond simply pumping out grease. Each visit includes a complete 7-point service:
- FOG layer measurement — we measure grease accumulation depth before cleaning to track your kitchen’s waste pattern and optimise future scheduling
- Complete pump-out — industrial vacuum extraction of all grease, solids, and wastewater from the trap
- Wall and baffle scraping — manual removal of hardened grease deposits that vacuuming cannot reach, including baffle plates and inlet/outlet pipes
- High-pressure jetting — hydro-jetting of inlet and outlet pipes to clear accumulated buildup in connecting drain lines
- Bacterial dosing — application of biological enzyme treatment to break down residual FOG between cleaning visits
- Structural inspection — checking seals, gaskets, baffles, and the trap body for cracks, corrosion, or damage that could cause leaks or compliance failures
- Documentation — digital service report with before/after photos, measurements, and DM-compliant cleaning certificate
AMC Plans (Annual Maintenance Contracts)
A maintenance contract guarantees fixed pricing, scheduled visits, and priority response — no surprise costs, no missed cleanings, no compliance gaps.
AMC maintenance plans start from AED 199/mo — including scheduled cleaning visits, pump-out and scraping, bacterial dosing, DM compliance certificates, digital service reports, and certified waste disposal. Frequency and scope are customised to your kitchen’s output and trap size. Contact us for a tailored AMC quote.
All plans include certified waste disposal with documented chain-of-custody — required by DM for audit compliance.
Maintenance Between Professional Visits
These steps extend the time between professional cleanings and keep your trap running efficiently:
Daily Tasks (Kitchen Staff)
- Scrape all plates and pans into waste bins before washing — this alone reduces FOG entering the trap by up to 40%
- Wipe down fryers, grills, and cooking surfaces with dry towels before washing
- Never pour cooking oil down any drain — use a designated waste oil container
Weekly Tasks (Kitchen Manager)
- Check the trap’s inspection port — if you can see a thick grease layer, call for service
- Run hot water (not boiling) through the trap for 2 minutes to keep fats moving
- Clean sink strainers to prevent food solids from entering the trap
Monthly Tasks
- Add enzyme-based biological treatment to break down residual FOG
- Check for unusual odours — persistent sewer smell indicates the trap needs immediate cleaning
- Verify the trap’s water seal is intact (water should be visible in the inspection port)
7 Warning Signs Your Trap Needs Immediate Service
- Slow draining sinks — water takes more than 30 seconds to drain, indicating the trap is full
- Sewage odour in the kitchen — grease buildup breaks the water seal, allowing sewer gases to escape
- Grease visible in the inspection port — when the grease layer reaches 25% of trap depth, cleaning is overdue
- Water backing up into sinks or floor drains — the trap is at capacity and can no longer accept flow
- Gurgling sounds from drains — air trapped in blocked pipes creates distinctive gurgling noises
- Grease residue around the trap exterior — overflow from the trap body indicates seal failure or overfilling
- Failed DM inspection notice — if you’ve received a warning, call us immediately for same-day emergency service
What DM Inspectors Check
Being prepared for a Dubai Municipality inspection means having these items ready:
- Cleaning log — documented dates and details of every cleaning visit for the past 12 months
- DM compliance certificates — issued by your approved cleaning contractor after each service
- Waste disposal receipts — proof that extracted grease was disposed of at an approved facility
- Maintenance contract — a current AMC with a licensed cleaning company (Activity Code 900017)
- Trap sizing documentation — proof that the installed trap meets the capacity requirement for your kitchen’s output
Our AMC plans include all documentation in digital format, accessible anytime. Download the full compliance checklist.

Frequently Asked Questions
How often should I clean my grease trap in Dubai?
DM requires small traps (AG1–AG2) to be cleaned 4 times per month and larger traps at least twice per month. High-volume kitchens should increase frequency. The rule of thumb: clean when the grease layer reaches 25% of the trap depth. Read our full guide on DM cleaning frequency requirements.
What is included in a grease trap AMC?
An Annual Maintenance Contract includes scheduled cleaning visits, pump-out and scraping, bacterial dosing, structural inspection, DM compliance certificates, digital service reports with photos, and priority emergency response (Standard and Premium plans).
How much does grease trap maintenance cost?
AMC maintenance plans start from AED 199/month, customised to your kitchen’s output and cleaning frequency requirements. Multi-location discounts are available. See our full cost guide.
Can I clean the grease trap myself?
Basic daily maintenance (scraping, strainer cleaning) should be done by kitchen staff. However, professional pump-out and disposal must be performed by an Activity Code 900017 licensed contractor. Self-disposal of grease waste is illegal in all UAE emirates.
What happens if I miss a scheduled cleaning?
A missed cleaning means the trap continues accumulating FOG. If an inspector visits during this period, you face fines and possible closure. Our AMC plans include automated scheduling reminders and backup dates to prevent missed visits.
Do you provide DM certificates after each cleaning?
Yes. Every cleaning visit generates a DM-compliant service certificate with date, technician details, waste volume extracted, disposal documentation, and before/after condition report.
What’s the difference between cleaning and maintenance?
Cleaning is pump-out and waste removal. Maintenance includes cleaning plus inspection, jetting, bacterial dosing, gasket checks, and documentation. Our maintenance service is a complete 7-point process — not just a pump-and-go operation.
Do you maintain grease traps outside Dubai?
Yes. We provide full maintenance services across all seven UAE emirates with dedicated teams in each region. Contact us for AMC pricing in your area.
