Professional cleaning, disinfection, and bacteriological testing for all tank types across all 7 UAE emirates. Municipality-compliant certificate issued after every service.
UAE's climate creates the perfect conditions for bacteria, algae, and sediment buildup
Warm stagnant water in a UAE tank is a growth environment for Legionella pneumophila, E. coli, and other waterborne pathogens. Six-monthly cleaning breaks the cycle before contamination can reach a level that affects occupant health.
UAE summer temperatures combined with any light penetration through older or degraded tank walls accelerate algae colonisation. Left unchecked, algae imparts colour, taste, and odour to the water and creates organic matter for bacteria to feed on.
UAE mains water carries dissolved calcium and magnesium salts that deposit on tank walls over time. Scale reduces effective tank capacity, reduces flow through outlet fittings, and provides a surface for biofilm to attach to.
Dubai Municipality, Abu Dhabi Municipality, and all other UAE emirates mandate minimum six-monthly tank cleaning. Failure to produce a valid cleaning certificate during a building inspection results in fines and a non-compliance notice.
Property owners and building managers carry a duty of care over the quality of water supplied to occupants. Regular professionally documented cleaning is the primary defence against waterborne illness claims.
Scale and microbial fouling accelerate degradation of tank fittings, float valves, and the inner liner itself. Regular cleaning removes the agents of this degradation and extends the operational life of the tank and its components.
A fully documented 5-step process meeting UAE Municipality standards
We isolate the tank from the supply, drain it completely, and remove the old water from site. Scheduling is coordinated around your property's peak-demand periods to minimise disruption.
High-pressure water jets remove loose sediment, scale, and biofilm from every interior surface. Technicians then manually scrub the walls, floor, inlet screen, and all accessible fittings to remove any remaining residue.
An approved chlorine-based disinfectant is applied across all internal surfaces at UAE Municipality-specified concentrations. Full contact time is observed before the solution is flushed.
The tank is refilled from the mains supply and a multi-parameter test is carried out on-site: free chlorine residual, pH level, and turbidity are measured and recorded. We do not leave until the water meets safe limits.
KHAZAAN issues a signed Municipality-compliant cleaning certificate immediately after each service. The document records the date, tank details, disinfectant used, test results, and technician identification. Store it with your building's compliance file.
We clean all types and sizes of water storage tanks across UAE
Water tank cleaning is not optional in UAE. It is a legal requirement.
Public Health Law No. 11 of 2003 requires all water storage tanks to be cleaned and disinfected every 6 months minimum.
Abu Dhabi Health Authority standards mandate biannual tank cleaning with documented records kept on-site.
Building regulations require regular water tank cleaning with a certified technician and written completion record.
All UAE municipalities follow GCC-wide SASO and WHO guidelines mandating minimum 6-monthly tank cleaning.
Every cleaning job comes with a signed, dated Municipality-compliant certificate. Required for building inspections, property sales, and corporate compliance audits.
The minimum legal requirement across all UAE municipalities is once every six months. High-risk premises, including hospitals, hotel kitchens, food-production facilities, and schools, typically need to clean every three months to meet their specific sector regulations. Residential properties that receive an inspection notice or building compliance request must produce a valid certificate dated within the past six months. Contact KHAZAAN on +971 50 958 3173 to arrange a schedule that keeps your property compliant automatically.
Non-compliance with water tank cleaning requirements in UAE carries financial penalties during building inspections. Beyond regulatory risk, an uncleaned tank accumulates sediment and biofilm over time, providing conditions in which Legionella, E. coli, and algae can establish. The health consequences for occupants, particularly children and elderly residents, are the more serious concern. Municipality inspectors can issue improvement notices and access denials until compliance is demonstrated.
The certificate issued after every KHAZAAN cleaning service records the date and time of service, the property address and tank location, the tank type and capacity, the cleaning and disinfection method used, the chemicals applied and their concentrations, the on-site water quality test results, and the technician's identification. This documentation meets the record-keeping requirements of Dubai Municipality, Abu Dhabi Municipality, and all other UAE emirate authorities.
A residential rooftop tank of 500 to 1,000 USG capacity takes approximately 2 to 3 hours from arrival to final water quality test and certificate issue. This includes draining, high-pressure washing, scrubbing, disinfection contact time, refilling, and testing. Commercial tanks above 2,000 USG typically require 4 to 8 hours depending on condition. Access to the tank hatch and water supply are required throughout.
Yes. KHAZAAN uses food-grade sodium hypochlorite solution applied at concentrations approved by UAE Municipality guidelines and WHO water safety standards. After the required contact time, the tank is thoroughly flushed and refilled with mains water. Before certifying the tank as safe, we measure the free chlorine residual in the refilled water to confirm it falls within the safe drinking water range. The tank is not returned to service until this check is passed.
