Water Tank Cleaning in Dubai
Physically scrubbed, disinfected, flushed and tested — then photographed, so you can see what the inside of your tank actually looked like.
Signs Your Tank Needs Cleaning Now
The six-month schedule exists for a reason, but any of these means booking sooner.
Brown, yellow or cloudy water at the tap, particularly after a quiet period or after building works, means sediment has been disturbed in the tank or the pipework. Stop using it for drinking and cooking and get the tank looked at.
Musty, earthy or sulphurous smells point to biological activity in the storage or distribution system. This does not come from the DEWA supply. It develops in the building's own tank and pipes after the water arrives.
Water tank cleaning in Dubai runs on a six-month cycle, and property inspections, audits and insurance renewals commonly ask for evidence of it. If nobody can tell you when the tank was last cleaned, it is overdue.
Construction debris, stagnant water and biofilm all accumulate in tanks during a build. A new property should have the tank cleaned and the system flushed before anyone moves in, and tested afterwards to confirm it.
Tank repairs, pipe replacement or booster pump work all open the system. Work carried out inside a tank without disinfecting afterwards can introduce contamination straight into the supply, which is the opposite of what the repair was for.
Extended holidays, Ramadan, or a vacant unit all reduce water turnover and leave water sitting. Stagnant water in a warm tank is the condition that matters most, so flush and disinfect before normal occupancy resumes.

Our 3-Step Cleaning Process
Scrubbing is what removes the contamination. Everything else supports it.
The tank is isolated from the supply and distribution system, and we photograph the condition inside before touching anything: sediment level, biofilm, corrosion and the state of the access hatch. Pre-clean samples are taken where testing is included, and it all goes into your report.
Walls, floor, baffles and the inlet and outlet fittings scrubbed with long-handled brushes and high-pressure water, then everything flushed out through the drain point. We do not fill a tank with disinfectant, drain it and call that cleaning, because chemicals do not remove sediment. The physical scrubbing is what takes the contamination out.
Sodium hypochlorite applied at the correct concentration and left for a minimum thirty-minute contact time, then flushed thoroughly and refilled. A chlorine residual check confirms the tank has been flushed clear rather than leaving disinfectant in your drinking water. Your report and photographs are issued the same day.
What Water Tank Cleaning Costs in Dubai
Larger tanks, underground tanks and buildings with multiple tanks are priced on total capacity and access. An underground tank is a different job from a rooftop one and needs confined space precautions, which is why we ask which you have when you book.
You get a fixed price before booking, with nothing added on the day. Water testing is quoted separately so you can decide whether you want it.

Why Choose WEFIX for Tank Cleaning
Physical cleaning of every internal surface before any disinfectant goes near it. Sediment does not dissolve, and a tank that has been chemically dosed without scrubbing still has everything on the floor that was there before.
You see what the inside of your tank looked like. Nobody climbs into their own water tank, which is exactly why this work should be documented rather than described.
Bacterial count, E. coli, coliforms, TDS, pH and chlorine residual, sampled before and after. A clean-looking tank and clean water are not the same claim, and the test is the only one that means anything.
Chlorine residual checked after refill to confirm the disinfectant has cleared. Leaving hypochlorite in the system is its own problem, and the check is the step that gets skipped when someone is behind schedule.
Villas are typically two to four hours. Buildings are sequenced tank by tank. No overnight outage on standard residential work.
DED licence 856870, ISO 9001 and ISO 45001 certified, third-party liability and workmen's compensation in place. Fire safety and first warden trained.
Tanks, Systems and Testing
We clean GRP and fibreglass, polyethylene, concrete and stainless steel tanks, rooftop and underground, along with booster sets and building distribution systems.

Water Tank Cleaning FAQs
How often should water tanks be cleaned in Dubai?
Every six months is the standard interval residential and commercial buildings in Dubai work to, and property inspections, audits and insurance renewals commonly ask for evidence of it. Hotels, schools and healthcare facilities are often required to clean more frequently under their own sector rules. If nobody can tell you when your tank was last done, treat it as due.
How much does water tank cleaning cost in Dubai?
A standard villa rooftop tank of 1,000 to 5,000 litres is AED 200 to 500. Larger tanks, underground tanks and multi-tank buildings are priced on total capacity and access requirements. You get a fixed price before booking and nothing is added on the day.
Can you clean the tank without cutting off our water?
For villas and small apartment tanks, expect a short interruption of 30 to 60 minutes while we isolate and drain down. Supply is back on before we leave. In larger buildings we clean one tank at a time, so the building keeps water throughout, with the schedule agreed in advance with building management.
Do you provide water quality testing?
Yes, as an add-on to the cleaning or on its own. Total bacterial count, E. coli and coliforms, Legionella culture through an accredited laboratory, TDS, pH, turbidity and free chlorine residual. Post-clean reports can go into your compliance file, which matters most for hotels, medical facilities and schools.
What if the tank is corroded or damaged?
We photograph and document anything structural at the pre-clean inspection: cracks, corrosion, damaged inlet and outlet fittings, compromised hatches. Surface crazing or minor delamination on GRP tanks we can treat with approved sealant coatings. Where the damage is significant, we give you a written report and recommendation you can take to other companies for independent quotes. We will not carry out a clean that a structural fault would make pointless.
What happens to the sediment and wastewater?
It is flushed out through the tank’s drain point and disposed of through the building’s drainage. We leave the roof or tank area clean.
Do you clean underground tanks?
Yes, along with buffer tanks and swimming pool tanks. Underground tanks need confined space precautions and are a different job from a rooftop clean, so tell us which you have when you book and we will price it correctly.
Do you work with building managers and owners' associations?
Yes, including annual contracts across multiple buildings. We schedule around occupancy, coordinate access with your FM team and provide the written reporting your records require.
Should we clean the tank after plumbing work?
Yes. Any work that opens the system, including tank repairs, pipe replacement or pump work, should be followed by disinfection of the affected sections. Work inside a tank without disinfecting afterwards can introduce contamination directly into the supply.
When Was Your Tank Last Cleaned?
Tell us the tank type and capacity and whether it is rooftop or underground. Fixed price before booking, photographs and a written report on completion.
