Water Tank Cleaning

What Is Water Tank Cleaning?

Water tank cleaning is the professional draining, scrubbing, and disinfection of overhead and underground water storage tanks to ensure safe, clean water supply. Our trained technicians remove sediment, algae, and bacterial biofilm from tank surfaces, apply municipality-approved chlorine disinfection, and test water quality before refilling. This essential service is mandated by Dubai Municipality every six months and protects building occupants from waterborne contamination and health risks. Clean water storage is not simply a maintenance task in the UAE but a regulated health and safety requirement for every property.

Our Water Tank Cleaning Process

Our technicians begin with a thorough inspection of the tank’s condition, checking for sediment accumulation, algae or biofilm growth, structural cracks, and the proper function of valves, float mechanisms, and overflow pipes. The tank is then drained safely, with care taken to manage water discharge without causing flooding or damage to surrounding areas. Once empty, our team enters the tank and manually scrubs all interior walls, floor surfaces, and corners using approved cleaning agents, removing all sediment, sludge, and biological material that has accumulated since the previous cleaning. After scrubbing, the tank is disinfected using chlorine-based solutions at concentrations specified by Dubai Municipality standards, with sufficient contact time maintained to ensure effective sanitisation. An anti-bacterial spray is applied to all surfaces as an additional protective measure. The tank is rinsed, refilled, and a water sample is collected and tested to verify cleanliness. A municipality-compliant cleaning certificate is issued for your records.

When You Need Water Tank Cleaning

Dubai Municipality requires water tank cleaning every six months, and maintaining this schedule is essential for regulatory compliance and occupant health. Beyond mandatory intervals, additional cleaning should be arranged if you notice discoloured water, an unusual taste or odour in your tap water, or visible sediment when running taps. Properties that have been vacant for an extended period should have tanks cleaned before reoccupation, as stagnant water promotes bacterial growth. Building managers should coordinate tank cleaning with scheduled maintenance shutdowns to minimise disruption to residents. New property handovers and pre-purchase inspections should include verification of the most recent tank cleaning certificate. If a water quality test returns unsatisfactory results, immediate tank cleaning and retesting are required.

Regional Considerations

Dubai’s hot climate accelerates biological growth inside water tanks, with rooftop overhead tanks particularly vulnerable due to solar heating that raises water temperatures to levels that encourage bacterial proliferation. The UAE’s desalinated water supply, while treated, can promote mineral sediment accumulation in storage tanks over time. Underground tanks in areas with high water tables or sandy soil conditions may be more susceptible to sediment infiltration. Dubai Municipality inspectors can request proof of regular tank cleaning during building inspections, and RERA compliance for residential buildings also requires documented water tank maintenance. Our cleaning certificates are formatted to satisfy all regulatory requirements and are accepted by municipality inspectors, RERA, and building management companies across Dubai and Abu Dhabi. We clean all tank types including GRP, concrete, and steel tanks in villas, apartment towers, and commercial buildings.
