Getting your mechanical, electrical and plumbing systems right before fabrication begins saves thousands of dirhams and months of re-work. Whether you are learning how to start a food truck business in the UAE or comparing numbers after reading about food truck manufacturing cost in the UAE, this guide gives you the engineering detail to size every MEP system correctly and pass Civil Defence and municipality inspections the first time.
Why MEP Planning Matters Before You Build
MEP planning determines whether a food truck passes inspection, operates safely in UAE summer heat, and runs profitably from day one. Retrofitting undersized electrical or plumbing systems after fabrication is expensive and sometimes structurally impossible, making upfront engineering the highest-return investment in any build.
In the UAE, a food truck faces overlapping authority approvals: the relevant municipality for food safety, the Roads and Transport Authority for vehicle compliance, UAE Civil Defence for fire and gas safety, and the local electricity authority for electrical connections. Errors at any layer lead to licence refusal or forced operational shutdown. Our food truck manufacturing service integrates MEP design from day one so structural routing, ventilation penetrations, and tank mounting positions are resolved before a single panel goes on the frame.
Electrical Power: Generator Sizing, Batteries and Shore Power
Electrical load calculation starts by summing the running watts of all equipment, adding the highest single surge wattage, and applying a 20 percent safety margin. Undersizing the generator is the most common and most costly food truck kitchen MEP setup mistake.
Generator Sizing by Truck Type
The table below lists verified running and surge wattages for common food truck equipment. Use these figures to build your load schedule before specifying a generator.

A small coffee truck needs 3,500 to 5,000 W. A burger or grill truck adding a griddle and freezer needs 6,000 to 7,500 W. A full-service truck with multiple cooking appliances and refrigeration needs 10,000 W or more. Always apply the 20 percent safety margin after totalling running watts plus the highest single surge load.
UAE mains voltage is 230 V single-phase and 400 V three-phase at 50 Hz. All electrical installations must comply with IEC 60364. The relevant authority is DEWA in Dubai, ADDC in Abu Dhabi, and SEWA in Sharjah.
Battery, Inverter and Shore Power Options
Shore power at a commissary or event site provides a 16 A single-phase supply at 230 V, giving 3,680 W continuous. A 30 mA residual current device is mandatory on any shore power connection, and the vehicle inlet must be a blue CEE 16 A socket conforming to IEC 60309.
A 3,000 W inverter running for five continuous hours requires 15,000 Wh of stored energy. Lithium iron phosphate deep-cycle batteries with a battery management system are the correct specification: they tolerate UAE summer temperatures, deliver consistent voltage to the inverter, and charge efficiently from the generator. Lead-acid batteries are not recommended given their temperature sensitivity and weight penalty.
Most UAE food trucks use a diesel generator as the primary source, a shore power inlet for commissary use, and a lithium battery bank for pre-cooling refrigeration before service begins. This combination provides redundancy and allows the generator to shut down during quiet service periods.
Gas Supply: LPG Cylinders, Regulators and UAE Safety Rules
UAE Civil Defence regulations permit a maximum of two LPG cylinders per food truck, each not exceeding 20 kg, stored in an external ventilated compartment at the rear of the vehicle with no internal access from the kitchen area. Civil Defence inspectors check this first.
The cylinder compartment must have external access only, be well ventilated to prevent gas accumulation, be protected from direct sunlight, and sit a minimum of one metre from generators and cooking appliances. Cylinders must be firmly secured against movement during transit.
Gas leak sensors are mandatory inside the kitchen and adjacent to the cylinder compartment. A triggered sensor must shut off the gas supply automatically or provide an audible and visual alarm. This is a Civil Defence requirement.
Pipe material inside the vehicle must be copper. Rubber hose is not permitted because it is susceptible to abrasion and heat degradation. Regulators must deliver 30 mbar outlet pressure and comply with EN 12864. Cylinders require testing every five years and have a maximum service life of fifteen years under ESMA standards. UAE LPG supply is available through Emirates Gas, ADNOC Distribution, and Al Saqr Gas.
Water and Plumbing: Fresh Tank, Grey Water and Sinks
Dubai Municipality requires hot and cold running water, a potable water system, and proper waste management on every food truck. Meeting this requirement involves correctly sizing the fresh water tank, installing a compliant grey water system, and fitting the correct sink configuration with adequate water heating capacity.
Tank Sizing
The fresh water tank minimum is 30 gallons, with 40 to 80 gallons recommended for a full service shift. Tanks must be FDA-approved NSF-certified polyethylene. The grey water tank must be at least 15 percent larger than the fresh water supply; a 30-gallon fresh tank therefore requires a minimum 35-gallon grey water tank. This ratio ensures grey water capacity is never exhausted before fresh water runs out.
Grey water must be disposed of at an approved grease interceptor at the commissary kitchen. Discharge to stormwater drains or open ground is prohibited.
Sink and Water Heater Requirements
A three-compartment sink is required on every food truck. The wash compartment needs water at a minimum of 110 degrees Fahrenheit with detergent. The sanitise compartment requires either water at 171 degrees Fahrenheit held for 30 seconds or a correctly dosed chemical sanitiser. A separate dedicated handwash basin is also required; it cannot form part of the three-compartment sink and must supply both hot and cold running water independently.
A propane tankless water heater is the most space-efficient option and the most popular choice on UAE food trucks. An electric tankless heater rated at 19.2 kW delivers approximately two gallons per minute. The heater must recover three to six gallons within thirty minutes to support continuous sink operations during peak service.
Exhaust Hood and Ventilation for a Mobile Kitchen
A Type I grease-rated exhaust hood is required for all cooking equipment that produces grease-laden vapour, in accordance with NFPA 96. The correct airflow is 150 CFM per linear foot of hood length, giving typical food truck systems a range of 900 to 1,500 CFM. Our kitchen exhaust and ventilation service handles this calculation and the complete hood installation.
The exhaust fan must activate automatically when any cooking appliance is switched on. When the fire suppression system activates, makeup air supply must shut off automatically to prevent the agent from dispersing before it suppresses the fire. Access panels are required every twelve feet and at every direction change in the ductwork. Hood and duct cleaning must be carried out monthly by a professional contractor, with an annual deep clean. Cleaning records are inspected during Civil Defence and municipality audits.
Makeup air design matters particularly in the UAE. Unconditioned outdoor air at 45 degrees Celsius in summer creates significant heat stress for kitchen staff. A short-cycle makeup air arrangement that introduces supply air across the hood face rather than directly into the kitchen reduces heat load while satisfying the NFPA 96 negative pressure balance requirement.
Fire Suppression: UAE Civil Defence Requirements
A UL 300-listed wet chemical fire suppression system is mandatory on every food truck operating grease-producing cooking equipment. The system uses potassium acetate agent, which creates a saponification foam blanket over burning grease. The Ansul R-102 is the accepted standard in the UAE market.
On activation, the system deploys within 3 to 10 seconds at approximately 180 to 220 degrees Celsius, simultaneously shutting down the gas supply and triggering the automatic exhaust fan interlock. Coverage must include all grease-producing appliances, the plenum inside the hood, and the duct entry point.
Installation costs run from AED 11,000 to AED 22,000 fully installed. UAE Civil Defence approval is required before installation begins, and the contractor must hold a current Civil Defence approval. Engaging an unapproved contractor results in rejection at inspection regardless of technical quality.
A certified technician must inspect the system every six months. An annual full inspection with pressure testing is required to maintain the Civil Defence certificate, which is renewed annually. A minimum of two ABC-rated portable fire extinguishers must be mounted in accessible positions on the vehicle. Insurance underwriters offer up to 25 percent discounts on vehicles equipped with approved suppression systems.
UAE Compliance: Civil Defence and Municipality Approvals
The UAE approval process runs across multiple authorities, and the sequence matters because some approvals are prerequisites for others. Submitting to the wrong authority before the vehicle fit-out is certified leads to delays of several additional weeks.
The approval pathway for Dubai follows these steps.
- Complete the vehicle fit-out and all MEP installations to the standards described in this guide before applying for any inspection.
- Register on the Dubai FoodWatch platform and submit the food permit application to Dubai Municipality Food Safety Department. The permit fee is AED 160.
- Book a Dubai Civil Defence inspection covering fire suppression, extinguisher placement, LPG safety, ventilation, and emergency exits. The inspection fee is AED 1,500 to AED 2,500.
- Submit to RTA for vehicle safety assessment covering structural modification and load distribution.
- Engage DEWA for electrical connection approval if shore power is to be used at a fixed location.
- Allow three to six weeks for the full approval cycle after fit-out is complete.
In Abu Dhabi, applications go through the TAMM portal to ADDED, ADAFSA, DMT, and Abu Dhabi Civil Defence. A monthly event permit is AED 500 and an annual permit is AED 3,000. Abu Dhabi Civil Defence also mandates diesel fuel rather than petrol, which must be accounted for during vehicle specification. In Sharjah, the annual permit costs AED 3,000 and is currently available to UAE citizens only.
Across all emirates, staff food handler certificates are required and renewed every two years. The vehicle Civil Defence certificate is renewed annually. Our restaurant MEP engineering team prepares the technical documentation packages for Civil Defence and municipality submissions, reducing approval time compared to self-prepared drawings.
