Certified water tank cleaning company in Dubai
The water in your taps is only as clean as the tank it is stored in. In the UAE, rooftop and underground tanks sit in heat for most of the year. Sediment settles on the floor, biofilm grows on the walls, and dust and insects get in through worn lids and vents. None of it is visible from the tap until the water already tastes, smells or looks wrong.
Green Horizon has cleaned water tanks across the UAE since 2007. We are approved by Dubai Municipality, and every job ends with a certificate of service and before-and-after photographs, accepted by building management and authorities. We clean tanks for villas, residential towers, hotels, schools, hospitals and industrial sites in all seven emirates.
What our water tank cleaning includes
- Inspection — tank condition, lid seal, vents, inlet, outlet and overflow
- Draining — supply isolated and standing water fully removed
- Sludge removal — settled sediment, scale and debris taken out of the tank, not flushed into your pipes
- Pressure cleaning and scrubbing — walls, floor and ceiling cleaned of biofilm and algae
- Disinfection — food-grade chlorination at the correct concentration and contact time
- Flush, refill and check — the tank is rinsed, refilled and the water checked
- Certificate — dated certificate of service with photographs
Cleaning happens in that order for a reason. Disinfectant does not work on surfaces still coated in sludge and biofilm, so the tank is physically cleaned first and disinfected second.
Why choose Green Horizon for water tank cleaning

Dubai Municipality approval, plus a certificate of service after every clean, so you have a record for your building, your landlord or an inspection.
Safe for drinking water

Signs your water tank needs cleaning
- A metallic, earthy or musty taste or smell
- Cloudy, yellow or brown water, or visible particles
- Pressure dropping across several taps at once
- Green algae or slime visible inside the tank
- A cracked or loose tank lid, or insects around the inlet
- More than six months since the last clean — or no record at all
Each of these is explained in 7 signs your water tank needs cleaning, and our guide to how often to clean your water tank in Dubai covers scheduling.
How often should water tanks be cleaned in Dubai?
Dubai Municipality recommends cleaning and disinfecting water tanks at least twice a year, for homes and commercial buildings alike. UAE heat accelerates bacterial and algae growth in stored water, which is why the interval here is shorter than in cooler climates.
Clean sooner than scheduled after plumbing or construction work, after any contamination event, if the tank lid has been damaged, or if anyone in the building has repeated stomach upsets that could be water-related.
How much does water tank cleaning cost in Dubai?
Pricing depends on the tank, so any fixed rate quoted over the phone is a guess. The cost is driven by:
- Capacity — gallons or cubic metres, and the number of tanks
- Tank type — rooftop, underground, GRP sectional, Syntex or concrete
- Access — rooftop height, manhole size, underground chambers
- Condition — how much sludge and scale has built up since the last clean
- Supply planning — whether the work has to be staged or done overnight

Clean tanks, clean pipes
A clean tank feeding contaminated pipework still delivers poor water. Buildings with a history of discolouration or bacterial problems often need the distribution pipes treated too — see pipeline cleaning and disinfection and why UAE buildings need pipeline disinfection. Buildings with cooling towers should keep those on a separate hygiene programme — see cooling tower cleaning and disinfection.
