In Sharjah, clean water is essential for health and property compliance. Over time, water tanks accumulate sludge, bacteria, and biofilm, requiring professional intervention. Knowing the exact procedure a company follows gives you confidence in the quality of your water supply. Al Atta’s 7-step process for Certified Water Tank Cleaning ensures thorough sterilization, testing, and full regulatory compliance.

Initial Assessment and Isolation
The process begins with a careful inspection of the tank structure and water condition. Our technicians then safely isolate the tank from the main water supply and drainage system. This critical step ensures no contaminated water can enter the property’s plumbing lines or public water network during the cleaning process, maintaining the integrity of your water supply.
High-Pressure Sludge and Sediment Removal
The next stage involves draining the remaining water and removing all accumulated sludge, sediment, and biofilm from the tank floor and walls. We use specialized, high-pressure equipment and non-abrasive tools to manually scrub and remove stubborn deposits. This ensures every surface is clear before the sterilization stage, guaranteeing a highly effective Certified Water Tank Cleaning.
Sterilization with Municipality-Approved Disinfectant
After physical cleaning, the tank is sterilized using a powerful, yet safe, municipality-approved disinfectant. This chemical treatment eliminates any remaining harmful pathogens, bacteria, and viruses on the tank surfaces. The disinfectant is applied meticulously to every interior surface, achieving hospital-grade hygiene standards as part of our Certified Water Tank Cleaning commitment.
