Maintaining a clean water tank is essential for your health and comfort in Dubai’s hot climate. Over time, tanks collect dust, algae, and debris, from rooftop dust to sediment from municipal supplies. Without regular cleaning, your drinking and bathing water could be contaminated.
This guide covers everything you need to know about water tank cleaning in Dubai: ideal schedules, step-by-step cleaning, signs it’s time, and when to call the experts.
Why Keeping Your Water Tank Clean Matters
Even though the water might look clear, hidden contaminants can pose serious health risks:
- Sediment and rust can accumulate and clog filters or outlets
- Algae growth thrives in warm climates like Dubai’s
- Mosquito breeding in neglected tanks increases disease risks
- Microbial contamination from biofilm builds up and compromises water quality
Regular tank cleaning ensures your water is safe, clear, and free from particles and pathogens.
Cleaning Frequency Guidelines for Dubai
How often you clean depends on tank type, usage, and location:
| Tank Type | Recommended Cleaning Frequency |
| Underground tanks | Every 6 to 12 months |
| Elevated or rooftop tanks | Every 3 to 6 months |
| Open or partially covered | Every 3 months |
| After renovation/flood | Immediately |
Tanks closer to the rooftop or food-prep areas need cleaning more often due to dust and environmental exposure.
Signs It’s Time to Clean
Watch out for these clear warning signs:
- Strange tastes or odors (musty, metallic)
- Discolored or cloudy water
- Unusual sediment in taps
- Green or slimy buildup around edges
- Increased algae or insect presence
These indicate tank conditions are unsafe and require immediate cleaning.
Step-by-Step Water Tank Cleaning Process
1. Preparation
- Turn off the water inlet and disconnect the mains supply
- Drain the tank completely
- Put on gloves, a mask, and protective gear
2. Removing Debris
- Manually scoop out sludge and sediment
- Use a sturdy brush to scrub the walls and floor
3. Disinfecting
- Rinse thoroughly
- Apply a solution of warm water and bleach (1 part bleach to 100 parts water)
- Scrub again to remove biofilm
4. Rinsing
- Rinse multiple times until no bleach smell remains
- Allow full drainage
5. Refilling & Final Steps
- Reconnect the water supply
- Flush taps until clean, odor-free water runs
- Record the cleaning date and schedule reminders
DIY vs Professional Water Tank Cleaning
| Task | DIY Cleaning | Professional Cleaning |
| Basic sediment removal | Yes | Yes |
| Handling bleach solutions | Yes, with care | Yes, trained approach |
| Inspecting cracks & leaks | Limited | Thorough inspection |
| Disinfecting & flushing | Basic | Certified procedures |
| Safety & compliance | Riskier | Guaranteed |
If your tank is large, hard to access, or shows contamination signs, professional cleaning is safer and more effective.
Best Tank Materials and Maintenance in Dubai
Common tank materials include plastic (polyethylene), stainless steel, and concrete. Here’s how to care for each:
- Plastic Tanks – Scrub gently with soft brushes to avoid scratches
- Stainless Steel Tanks – Use non-abrasive cleaners and protect against rust
- Concrete Tanks – Inspect for cracks; apply food-grade liner if needed
Always repair damage promptly to prevent contaminants from entering.
Enhancing Tank Hygiene

- Install mesh screens on vents to block pests
- Fit first flush diverters to capture rooftop runoff debris
- Use a UV sterilizer or filter for added purification
- Monitor tank water regularly to detect early issues
Cost of Professional Cleaning in Dubai
- Small rooftop tank (< 500 L): AED 500- 1000
- Medium tank (1,000 – 2,000 L) : AED 1000 – 2000
- Large/Underground (> 5,000 L): AED 1600+

- Water shows persistent discoloration or odor
