Step-by-Step Cleaning Process
The cleaning process starts with removing loose debris and sediment using specialized vacuum equipment. Stubborn deposits require mechanical scrubbing with approved brushes and cleaning tools designed for water tank surfaces.
High-pressure washing follows mechanical cleaning, using potable water to remove loosened contaminants. The pressure washing process should cover all surfaces systematically, paying special attention to corners, pipe connections, and areas prone to sediment accumulation.
After physical cleaning, chemical disinfection becomes crucial. Approved disinfectants are applied according to manufacturer specifications, ensuring adequate contact time for effective microbial elimination. The tank is then thoroughly rinsed to remove all chemical residues.

What is the Procedure for Tank Cleaning
The standard procedure for commercial water tank cleaning follows internationally recognized protocols adapted for Dubai’s specific environmental conditions. The process typically spans 6-8 hours for medium-sized commercial tanks.
Initial Assessment and Preparation
Professional cleaning begins with comprehensive tank assessment, including water quality testing, structural inspection, and contamination level evaluation. This assessment determines the appropriate cleaning method and chemical requirements.
Safety measures are implemented before any cleaning activity begins. This includes proper ventilation setup, confined space entry protocols, and emergency response preparations. Only trained personnel should enter commercial water tanks.
Cleaning Execution
The actual cleaning process involves multiple phases, starting with complete water drainage and debris removal. Mechanical cleaning removes biofilm and stubborn deposits using specialized equipment designed for tank interiors.
Chemical treatment follows mechanical cleaning, using approved disinfectants to eliminate remaining microorganisms. The chemical contact time varies based on contamination levels and disinfectant type, typically ranging from 30 minutes to 2 hours.
Final rinsing removes all chemical residues, followed by comprehensive inspection to ensure cleaning effectiveness. Water quality testing confirms the tank meets safety standards before refilling.
Which Chemical is Used to Clean a Water Tank
Water tank cleaning requires specific chemicals approved for potable water systems. Chlorine-based compounds remain the most widely used disinfectants due to their effectiveness against a broad spectrum of microorganisms.
Primary Disinfectants
Sodium hypochlorite (liquid bleach) serves as the primary disinfectant for most commercial water tank cleaning applications. This chemical effectively eliminates bacteria, viruses, and fungi while remaining safe for potable water systems when properly applied.
Calcium hypochlorite (powdered bleach) offers similar effectiveness with longer shelf life, making it suitable for facilities requiring chemical storage. Both chemicals require careful handling and precise dosing to ensure safety and effectiveness.
Specialized Cleaning Agents
For heavily contaminated tanks, specialized cleaning agents may be necessary. These include algicides for algae control, scale removers for mineral deposits, and biocides for biofilm elimination. All chemicals must be food-grade and approved for potable water use.
The selection of appropriate chemicals depends on contamination type, tank material, and local water quality characteristics. Professional cleaning services have access to specialized chemicals not available to general consumers.
How Often Should a Water Tank be Cleaned
Commercial water tanks require more frequent cleaning than residential units due to higher usage rates and greater contamination risk. The recommended cleaning frequency varies based on several factors including tank size, usage patterns, and environmental conditions.
Standard Cleaning Schedule
Most commercial facilities should clean their water tanks every 6 months to maintain optimal water quality. High-usage facilities such as restaurants, hotels, and hospitals may require quarterly cleaning to prevent contamination buildup.
Dubai’s hot climate accelerates bacterial growth, potentially requiring more frequent cleaning during summer months. Facilities with poor water quality input may need monthly cleaning to maintain acceptable standards.
Factors Affecting Cleaning Frequency
Several factors influence the required cleaning frequency for commercial water tanks. These include incoming water quality, tank design, usage volume, and environmental exposure. Facilities near construction sites or industrial areas may need more frequent cleaning due to increased contamination risk.
Storage duration also affects cleaning needs. Tanks with rapid water turnover typically require less frequent cleaning than those storing water for extended periods. Regular water quality monitoring helps determine optimal cleaning schedules for specific facilities.

What Happens if a Water Tank is Not Cleaned
Neglecting commercial water tank cleaning leads to serious consequences affecting health, operations, and finances. Contaminated water poses significant health risks while potentially causing expensive equipment damage and regulatory violations.
Health Consequences
Dirty water tanks become breeding grounds for harmful bacteria, including Legionella, E. coli, and Salmonella. These pathogens can cause severe illnesses ranging from gastrointestinal infections to life-threatening respiratory diseases.
Biofilm formation creates protective environments for bacteria, making contamination increasingly difficult to eliminate. Once established, biofilms can continuously release pathogens into the water supply, creating ongoing health risks.
Operational Impact
Contaminated water affects equipment performance, causing scaling, corrosion, and blockages in plumbing systems. This leads to increased maintenance costs, reduced equipment lifespan, and potential system failures.
Poor water quality also impacts product quality in food service, manufacturing, and hospitality industries. Contaminated water can spoil food, damage products, and create unacceptable taste or odor issues.
