Advanced 8-Step Tank Cleaning Process Using Industry-Leading Technology & Safety Standards
At Karachi Tank Cleaning, we don't just clean tanks—we restore your water safety using advanced technology and certified procedures. Unlike traditional "home-run" services that rely on basic manual scrubbing with buckets and brushes, we employ professional-grade equipment and specialized disinfection chemicals that eliminate 99.9% of bacteria, algae, and harmful biofilm.
Our team is trained in confined space safety protocols and uses food-grade, eco-friendly chemicals approved by international health standards. Every service is completed with full documentation and a satisfaction guarantee.
We utilize professional-grade high-pressure jet washers (2000-3000 PSI) to blast away deep-rooted algae, biofilm, and sediment that manual scrubbing simply cannot remove.
After jet washing, we use commercial-grade wet/dry vacuum systems to extract all sludge, debris, and wastewater—leaving zero residue behind.
We use hospital-grade, food-safe disinfectants including Silver Hydrogen Peroxide and chlorine-based treatments that are far superior to household bleach.
❌ Manual buckets and brushes only
❌ Harsh industrial acids that damage tank structures
❌ Unverified or household cleaning products
❌ Untrained workers without safety equipment
Our certified technicians conduct a comprehensive assessment of your tank type (overhead, underground, RCC, commercial), size, accessibility, and contamination level. We deploy all necessary safety equipment including oxygen meters, ventilation fans, and confined space entry gear.
Using industrial-grade submersible pumps, we safely drain all water from the tank. For underground tanks, we ensure proper ventilation during this process. Water is directed to appropriate drainage systems.
Manual removal of accumulated sediment, dead insects, rust particles, and visible debris. This step prepares the tank surface for deep cleaning.
Using professional jet washers at 2000-3000 PSI, we blast away algae, biofilm, scale deposits, and stubborn contaminants from all tank surfaces—walls, floor, ceiling, and corners. This removes 99.9% of biological and mineral buildup.
Our commercial wet/dry vacuum systems extract all loosened sludge, debris, and wastewater. Unlike manual removal, this ensures zero residue is left behind that could re-contaminate your water.
We apply food-grade disinfectants (Silver Hydrogen Peroxide or approved chlorine treatments) to all internal surfaces. This kills remaining bacteria, viruses, and prevents future algae growth. All chemicals are WHO and EPA approved.
Multiple rinses with clean water remove all chemical residues. Our team conducts a thorough visual inspection and, if requested, can perform water quality testing to ensure safety standards are met.
We assist with tank refilling and provide you with a detailed service completion certificate, chemicals used, technician details, and recommended maintenance schedule.
We explicitly avoid:
❌ Harsh industrial acids (can corrode tank structures)
❌ Unknown or unverified cleaning products
❌ Chemicals not certified for drinking water systems
❌ Standard household bleach in excessive amounts
❌ Any product that could leave harmful residues
Water tank cleaning, especially for underground and confined spaces, requires strict safety protocols. Our team is certified in confined space entry procedures and uses professional safety equipment to protect both workers and your property.
