How often should water tanks be cleaned in Dubai and how much does it cost?

Dubai Municipality requires building water tanks to be cleaned every 6 months as a public health standard. In a rental property, water tank cleaning is the landlord's or building management's responsibility — not the tenant's. If you're a villa owner, you're responsible for your own tanks. Professional water tank cleaning in Dubai costs AED 150–AED 400 depending on tank size and number of tanks. The service includes draining, pressure washing the interior, disinfection with chlorine solution, rinsing, and a water quality test. Signs your tank needs cleaning: discoloured water, sediment, unusual taste or smell. Don't delay — contaminated water tanks in Dubai's heat are a genuine health risk.
