What Is Water Tank Cleaning?
Water tank cleaning is the process of draining a storage tank, removing the sludge and biofilm that build up inside it, scrubbing the walls and floor, disinfecting the surfaces and refilling with clean water. Done properly, it removes sediment, bacteria and algae at the source, so the water that reaches your taps is clean, clear and free from odour.
Every tank that stores water needs cleaning, whether it is a rooftop plastic tank, a GRP fiberglass tank in a plant room or an underground tank below a villa. As a guide, domestic and commercial tanks should be cleaned at least once or twice a year, and more often if the tank is in direct sun or the water is delivered by tanker. Tanks in the UAE heat are especially prone to algae and bacterial growth.
Khazzan's water tank cleaning service covers draining, sludge removal, scrubbing, disinfection and a final water check, and we issue a certificate after every job.

Why Regular Water Tank Cleaning Matters
UAE's climate creates the perfect conditions for bacteria, algae, and sediment buildup
Bacteria and Legionella
Stagnant water tanks breed Legionella, E.coli, and other pathogens. Regular cleaning eliminates these health risks.
Algae Growth
UAE's heat and sunlight cause rapid algae buildup inside tanks, affecting water colour, taste, and safety.
Sediment and Scale
Minerals in UAE water leave scale deposits on tank walls and fittings over time, reducing capacity and flow rate.
Municipality Compliance
Dubai and Abu Dhabi Municipality require cleaning every 6 months. Non-compliance carries fines and building inspection failures.
Health Protection
Contaminated water tanks are a leading cause of waterborne illness in UAE. Clean tanks protect your family and staff.
Tank Longevity
Regular cleaning prevents internal corrosion, fitting damage, and early tank failure, extending tank life significantly.

Frequently Asked Questions
How often should a water tank be cleaned in UAE?
Dubai Municipality and Abu Dhabi Municipality both require water tanks to be cleaned at least every 6 months. Commercial buildings, hospitals and schools may require quarterly cleaning. Khazzan can set up a recurring service schedule for you.
Is water tank cleaning mandatory in UAE?
Yes. Under Dubai Public Health Law No. 11 of 2003 and equivalent Abu Dhabi Municipality standards, all water storage tanks must be professionally cleaned and disinfected every 6 months. Non-compliance can result in fines during building inspections.
Do you provide a cleaning certificate after the service?
Yes. We issue a signed Municipality-compliant cleaning certificate after every job, recording the date, tank details, cleaning method, and technician information. This is required for building inspections and compliance records.
How long does water tank cleaning take?
A standard rooftop residential tank (500-1,000 USG) takes 2-3 hours including draining, washing, disinfection, refill, and testing. Larger commercial tanks may take 4-8 hours depending on size and condition.
What chemicals do you use to disinfect the tank?
We use approved sodium hypochlorite (chlorine) solution at concentrations recommended by UAE Municipality and WHO guidelines. All chemicals used are food-grade safe and fully neutralised before the tank is put back into service.
How is underground water tank cleaning different from rooftop tanks?
Underground water tank cleaning requires confined-space entry procedures, specialist ventilation and pumping equipment to remove sediment that settles at depth, and buoyancy-safe dewatering. Our technicians are trained specifically for underground and basement tank access.
How often does a commercial water tank need cleaning?
Commercial water tank cleaning is typically required every 3 months for hotels, hospitals and schools, and every 6 months for offices and labour camps, depending on occupancy and local Municipality requirements. We can set up a recurring commercial cleaning contract.
