Water Tank Cleaning & Disinfection in Jeddah
Azl delivers water tank cleaning & disinfection in Jeddah with a method that starts with diagnosis, selects the system that suits the city's conditions, and ends with testing and a written warranty. Tank cleaning covers emptying the tank, removing sediment and silt, washing the walls, floor and roof, then disinfecting with a product suitable for drinking water at a set concentration and contact time following WHO guidance and the product's data sheet, followed by rinsing, refilling and measuring residual chlorine.

Our technical recommendations for water tank cleaning & disinfection in Jeddah
Coastal humidity
High humidity in Jeddah affects how materials cure and bond, so we schedule application in the least humid hours, measure surface moisture before starting, and choose materials that withstand the coastal environment and protect rebar from corrosion.
High groundwater
A high water table across wide areas of Jeddah means underground tanks and foundations face water pressure from outside, so we treat walls from inside with materials that resist negative pressure and recommend membranes for foundations rather than coating alone.
Hot rooftop tanks
In Jeddah'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.
Humidity and corroded fittings
Humidity in Jeddah speeds up rust on floats, valves and metal lids, and rust can reach the water; we record fittings' condition in the cleaning report and recommend replacing corroded parts.
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
