Safe Water Tank Cleaning Services in Abu Dhabi
When did you last look inside your water tank? Most people never do. ADDC delivers clean water to your meter, but from there the tank and the water at your taps are your responsibility. Water tank cleaning is the draining, scrubbing and disinfection of a storage tank to remove sediment, algae and bacteria. Quality Care UAE cleans rooftop and underground tanks across Abu Dhabi for villas, towers, hotels and offices, and gives you a certificate and test results after every job.

Why Water Tank Cleaning in Abu Dhabi Is Essential
Abu Dhabi summers pass 45°C. Rooftop tanks heat up in the sun, and water that sits still at that temperature lets bacteria and algae grow fast. Fine desert dust enters through vents and loose lids and settles as sludge on the tank floor. Underground tanks in villas and compounds collect even more sediment over time.
The Abu Dhabi water code, issued by the Regulation and Supervision Bureau and now under the Department of Energy, sets minimum cleaning intervals for every tank. Underground and ground-level concrete or GRP tanks need cleaning every 6 months. Rooftop, plastic, fibreglass and galvanised tanks need it at least once a year. If a water test fails, the tank must be cleaned again within 48 hours. Read the full Abu Dhabi water tank cleaning rules.
Warning Signs Your Water Tank Needs Immediate Cleaning
Ignoring these signs lets bacteria, algae and sediment build up in the water you use every day.
01 Foul Smell or Strange Taste
A musty, earthy or rotten-egg smell, or an odd taste, means bacteria or algae are growing in the tank.
02 Cloudy or Discoloured Water
Yellow, brown or murky water points to rust, sediment or sludge stirred up from the tank floor and reaching your taps.
03 Visible Sludge or Algae
Green or black growth on the tank walls means the tank has gone too long without cleaning and disinfection.
04 Sudden Drop in Water Pressure
Sludge and debris slowly block the tank outlet and the connected pipes, so pressure falls at several taps at once.
05 Unexplained Stomach Illness
If family members keep getting stomach upsets with no clear cause, stored water can be the source and should be tested.
06 Past Your Cleaning Due Date
Even when the water looks fine, a tank past its code interval of 6 or 12 months is due for cleaning.

How We Clean Your Water Tank, Step by Step
The same process every time, with no shortcuts and no half-drained tanks.
Step 1: We Check the Tank First
We inspect the tank inside and out for cracks, rust, damaged lids and open vents, then shut the inlet valve so no fresh water enters during cleaning.
Step 2: We Drain It Completely
The tank is pumped out fully, including the stagnant water at the bottom, so every surface can be cleaned.
Step 3: We Remove All the Sludge
Sediment and sludge are removed from the tank floor by hand and by pump, so nothing is left to stir up when the tank is refilled.
Step 4: We Wash It With High Pressure
Walls, floor, ceiling and fittings are scrubbed, then pressure-washed to clear biofilm and algae.
Step 5: We Disinfect the Tank
We apply food-grade sodium or calcium hypochlorite, the disinfectants the Abu Dhabi code allows, at the permitted concentration.
Step 6: Rinse, Test and Certify
We rinse and refill the tank, check that residual chlorine is within the 0.2 to 1.0 mg/l range, and hand you the certificate and report.

Types of Water Tanks We Clean in Abu Dhabi
Each tank material and location has its own cleaning interval under the Abu Dhabi code, and its own cleaning method.
Underground Water Tanks
Common in villas and compounds. They collect the most sediment, so underground concrete tanks need cleaning every 6 months.
Overhead Water Tanks
Rooftop tanks on apartments and offices face direct sun, which warms the water and speeds up algae growth.
Glass-Reinforced Plastic (GRP) Tanks
Strong and widely used in large buildings and hotels. Ground-level GRP tanks need cleaning every 6 months, rooftop ones yearly.
Polyethylene and FRP Tanks
Plastic and fibreglass tanks in villas and smaller buildings need gentle products, and the code sets a minimum of once a year.
Concrete Tanks
Found mostly in older buildings. The walls can crack over time, so we check for damage on every visit.
Metal and Stainless Steel Tanks
Common in commercial and industrial sites. We check for rust and corrosion and clean with suitable products.
Not sure what type of tank you have? You do not need to know. Our technician identifies the tank type and its cleaning interval during the inspection and explains it to you.

Frequently Asked Questions (FAQs)
How often should I clean my water tank in Abu Dhabi?
It depends on the tank. Underground and ground-level concrete or GRP tanks need cleaning every 6 months. Rooftop, plastic, fibreglass and galvanised tanks need it at least once a year. Clean again within 48 hours if a water test fails.
What happens if I don't clean my water tank?
Bacteria such as E. coli and Legionella can grow in warm, still water, and sediment builds up. A failed inspection or water test also means notifying residents and re-cleaning within 48 hours.
Is your cleaning process safe for drinking water?
Yes. We only use food-grade sodium or calcium hypochlorite, the disinfectants the Abu Dhabi code allows, and rinse until residual chlorine is in the safe range.
Do you clean underground and overhead tanks?
Yes. We clean underground, ground-level and rooftop tanks made of concrete, GRP, polyethylene, fibreglass and steel.
How long does water tank cleaning take?
A villa rooftop tank takes 2 to 4 hours and an apartment building tank 4 to 8 hours. Large commercial or underground tanks can take a full day, sometimes 2 days.
