Water Tank Cleaning done properly
Every villa and building in the UAE stores water on site, and that stored water sits in heat for long periods. Sediment settles, biofilm develops on the tank walls, and if a lid seal or vent screen has failed, dust and insects find their way in. None of this is visible at the tap until it is severe, which is why tank cleaning is the most commonly skipped item on any maintenance schedule.
We clean and disinfect GRP, polyethylene and concrete storage tanks to a documented procedure, with certified operatives, food-grade equipment and a full report on completion. Municipality guidance recommends cleaning at least twice a year, and in our experience that interval is the difference between a routine job and an unpleasant discovery.
Every job is confirmed with a fixed written quotation before work begins.

Our seven-stage method
Every water tank cleaning job follows the same documented seven-stage method, whether it is a single call-out or a full building program.
Access survey and safe isolation
We inspect tank location, access route and capacity, arrange safe access equipment where the tank is at height, and plan the supply isolation so disruption is kept to a short, agreed window.
Draining and sediment removal
The tank is drained down and the accumulated sludge and sediment at the base is removed physically. This is the material that no amount of chemical treatment alone will address.
Mechanical scrubbing of all internal surfaces
Walls, base, corners and internal baffles are scrubbed with dedicated tank-cleaning equipment to break down biofilm from the surfaces it has bonded to.
High-pressure wash and full rinse
The entire interior is pressure-washed and the residue is extracted, leaving surfaces genuinely clean rather than smeared. The tank is inspected under light at this stage.
Disinfection with approved chemistry
A food-grade chlorine-based disinfectant is applied at the correct concentration and given the required contact time, then thoroughly rinsed so no chemical taste or residue is carried into the supply.
Fittings and structural inspection
Lid seals, vent screens, overflow arrangements, inlet valves and float mechanisms are inspected and reported. Any crack, leak or failed component is photographed and quoted separately.
Refill, verification and certification
The tank is refilled, the supply is verified at the taps, and you receive a cleaning certificate with before-and-after photographs and the date your next clean is due.

Tank Cleaning, frequently asked questions
At least twice a year is the standard recommendation for residential properties in the UAE. Buildings with high occupancy, or tanks in exposed rooftop positions, benefit from a quarterly schedule.
A typical residential tank clean takes three to four hours from isolation to refill. We agree the window in advance so it falls at the least disruptive time of day for the household.
Yes. We use food-grade, potable-water-approved disinfectants at controlled concentration, and the tank is thoroughly rinsed after the required contact time so nothing is carried into your supply.
Yes, along with polyethylene tanks. The cleaning method and equipment are adapted to the tank material and to its internal construction.
Yes. You receive a cleaning certificate together with photographs of the tank interior before and after, which is often required by building management or for property handover.
Yes. We handle multi-tank buildings, phasing the work so the building retains supply throughout, and issue consolidated documentation for the facilities management team.
