If you notice any of the following, your water tank requires immediate cleaning:
Dirty or discoloured water from taps
Unpleasant smell or taste in the water supply
Sediment or particles appearing in taps and filters
Visible algae growth inside the tank
Rust particles in the water
Reduced water quality across the property
A long period since the last cleaning — more than 6 months
A failed Dubai Municipality inspection
Every Dotless water tank cleaning follows a structured, DM-compliant process using approved cleaning chemicals and ULV disinfection technology.
The tank is fully drained and all residual water removed, providing complete access to every internal surface before cleaning begins.
We spray the internal tank surfaces with HygienX, applied across all walls, floor, and internal areas. The chemical is left for the required contact time to break down sludge, algae, biofilm, and contaminant buildup.
After the chemical has taken effect, our technicians manually scrub every internal surface — walls, floor, and corners — removing loosened sludge, sediment, algae, and deposits that spray alone cannot lift.
The tank is thoroughly rinsed and flushed until all cleaning chemical is completely washed away, leaving the internal surfaces clean and residue-free.
Before the tank is returned to service, we disinfect it using a ULV (Ultra-Low Volume) machine. ULV fogging distributes disinfectant as a fine mist across every internal surface — reaching areas manual application can miss and ensuring complete sanitisation before the tank is refilled.
We conduct a final quality inspection to confirm the tank meets Dubai Municipality hygiene standards, then issue a DM Cleaning Completion Report together with before-and-after photographs.
