Our technical recommendations for water tank cleaning & disinfection in Najran
Hot rooftop tanks
In Najran's summer, exposed rooftop tanks heat up, and warm stagnant water favours bacteria and algae; so we check the lid, vents and shading at every clean and recommend a pre-summer clean.
Inspection before pricing
Every building in Najran has its own condition, so we rely on an on-site inspection to set the material, thickness and cost accurately, and offer a remote preliminary diagnosis through the smart assistant.
Materials we choose from
- Chlorine disinfectant suitable for drinking water: Sodium or calcium hypochlorite, preferably carrying a drinking-water treatment certification such as NSF/ANSI/CAN 60.
- Submersible pumps and sediment suction: To empty the tank and draw silt and sediment from the bottom without stirring it into the network.
- Pressure washing and non-metallic brushes: To remove deposits and growth from the walls without scratching the lining or internal coating.
- Residual chlorine test kits: To confirm after rinsing and refilling that the chlorine level is within limits suitable for use.
- Ventilation, lighting and protective equipment: For working inside ground tanks, which are confined spaces.
Work stages
- Stop the tank's supply and empty it, coordinating water provision during the work
- Ventilate the ground tank and secure entry, then vacuum sediment and silt from the bottom
- Wash the walls, floor, roof and openings and remove growth and deposits
- Disinfect at the concentration and contact time set by WHO guidance and the product's data sheet
- Drain the disinfection solution, rinse with clean water, refill and measure residual chlorine
- Inspect the tank and its covers and document its condition with photos in a report with recommendations
