Our Advanced 8-Step Tank Cleaning Procedure

At Accurate Fumigation, we use state-of-the-art technology and proven methods to ensure your water tank is thoroughly cleaned, disinfected, and safe for use. Our procedure goes beyond traditional manual scrubbing to deliver superior results.

1

Initial Inspection & Assessment

Our certified technicians conduct a comprehensive inspection of your water tank to:

  • Assess the level of contamination and sediment buildup
  • Check for structural damage, cracks, or leaks
  • Identify the type of tank (underground/overhead/commercial)
  • Determine the appropriate cleaning method and chemicals needed
  • Measure water capacity and estimate cleaning time
2

Complete Water Drainage

We use heavy-duty submersible pumps to efficiently drain all water from your tank:

  • High-capacity pumps: Can drain up to 500 gallons per hour
  • Safe disposal: Water is directed to proper drainage systems
  • Minimized disruption: Quick drainage process reduces downtime
  • Underground tanks: Specialized pumps for deep water extraction
3

Sludge & Sediment Removal

Using industrial vacuuming technology, we remove all accumulated debris:

  • Industrial vacuum systems: Remove sludge without leaving residue
  • Deep cleaning: Extract sediments from corners and bottom surfaces
  • Wet & dry vacuuming: Handle both liquid sludge and dried deposits
  • Complete extraction: No manual scooping that leaves biofilm behind
4

Pre-Treatment Chemical Application

We prepare and apply a specialized disinfection solution:

  • Chlorine solution: Medical-grade for bacterial elimination
  • Potassium permanganate: Removes algae and organic matter
  • Proper concentration: Calculated based on tank size and contamination level
  • Contact time: Solution is left for 15-20 minutes for maximum effectiveness
5

High-Pressure Jet Washing

This is where our service excels beyond traditional methods:

  • High-pressure equipment: 2000-3000 PSI water jets
  • Deep-rooted algae removal: Eliminates biofilm from walls and floor
  • 360-degree coverage: Every inch of the tank interior is cleaned
  • Corner & edge cleaning: Specialized nozzles reach difficult areas
  • Removes bacterial buildup: That manual scrubbing cannot eliminate
6

Manual Scrubbing & Detailing

Our team performs thorough manual cleaning for areas requiring special attention:

  • Industrial brushes: Scrub walls, floor, and corners
  • Long-handle mops: Clean overhead tank ceilings
  • Detail work: Clean inlet/outlet pipes, valves, and fittings
  • Stain removal: Address rust stains and mineral deposits
7

Final Disinfection & Rinsing

We conduct multiple rinse cycles to ensure complete cleanliness:

  • First rinse: Remove all chemical solution and loosened debris
  • Second rinse: Fresh water wash to eliminate any residue
  • Final disinfection spray: Light chlorine treatment on all surfaces
  • Water quality check: Ensure no chemical taste or odor remains
  • Complete drainage: Remove all rinse water using submersible pumps
8

Inspection, Sanitization & Refilling

Final quality assurance before handing over:

  • Visual inspection: Check for any missed spots or contamination
  • Tank lid cleaning: Clean and disinfect the tank cover
  • Seal check: Ensure proper sealing to prevent pest entry
  • Refilling assistance: Help with initial refilling if needed
  • Documentation: Provide service completion certificate

Technology & Sanitation Standards

We prioritize advanced technology over basic manual methods to deliver superior cleaning results:

High-Pressure Jet Washing System

Why it matters: High-pressure water jets (2000-3000 PSI) can remove deep-rooted algae, bacterial biofilm, and mineral deposits that manual scrubbing cannot reach. This technology ensures complete removal of contaminants from tank walls, corners, and floor surfaces.

Our equipment: Professional-grade pressure washers with adjustable nozzles for different tank types and contamination levels.

Industrial Vacuuming Technology

Why it matters: Industrial vacuum systems suck out sludge and sediments completely without leaving residue. Traditional bucketing methods leave behind bacterial biofilm and organic matter that can quickly contaminate the tank again.

Our equipment: Heavy-duty wet/dry industrial vacuums with HEPA filtration to safely remove all contaminants.

Specialized Equipment for All Tank Types

We have the proper gear to handle various tank configurations:

  • Underground (RCC) tanks: Oxygen masks, safety harnesses, confined space equipment
  • Overhead tanks: Extension ladders, safety ropes, elevated platform tools
  • Commercial tanks: Large-capacity pumps, industrial-grade cleaning systems

Why Basic Methods Fall Short

Many small services in Karachi still use outdated methods that compromise water quality:

  • Manual buckets & brushes only: Leave behind bacterial biofilm and sediments in corners
  • No industrial vacuuming: Sludge residue remains, providing breeding ground for bacteria
  • Improper chemical handling: Using harsh industrial acids that damage tank structure
  • Inadequate safety measures: Risk to workers and potential contamination

Specialized Disinfection Chemicals

We use safe, high-grade disinfectants specifically formulated for water storage systems:

Silver Hydrogen Peroxide (H₂O₂ + Ag⁺)

Primary disinfectant for premium service

  • Food-grade quality: Safe for drinking water applications
  • Broad-spectrum antimicrobial: Kills bacteria, viruses, algae, and fungi
  • No harmful residues: Breaks down into water and oxygen
  • Long-lasting protection: Silver ions provide residual antimicrobial effect
  • Safer than chlorine: No toxic byproducts or strong odors

Calcium Hypochlorite (Pool-Grade Chlorine)

Standard disinfectant for regular service

  • Medical-grade chlorine: Used in hospitals and water treatment facilities
  • Effective concentration: 5-10 ppm for tank disinfection
  • Controlled application: Precise dosing based on tank volume
  • Complete rinsing: Multiple water flushes remove all residual chlorine
  • WHO approved: Meets international water disinfection standards

Potassium Permanganate (KMnO₄)

Algae & organic matter treatment

  • Powerful oxidizer: Breaks down organic compounds and algae
  • Removes odors: Eliminates musty smells from tank water
  • Iron & manganese removal: Treats rusty water problems
  • Safe concentration: 2-4 mg/L for tank treatment
  • Color indicator: Pink/purple color shows active treatment

Chemicals We NEVER Use

Your safety is our priority. We strictly avoid harmful substances:

  • Hydrochloric Acid (HCl): Damages tank structure, creates toxic fumes
  • Industrial bleach: Contains additives unsafe for drinking water
  • Harsh alkaline cleaners: Can corrode metal fittings and pipes
  • Household detergents: Leave harmful residues, difficult to rinse completely
  • Unknown chemical mixtures: Unverified safety and effectiveness

Chemical Safety & Handling

Safety Measure Our Standard Practice
Chemical Storage Sealed containers, labeled clearly, stored in cool dry place
Mixing Procedures Precise measurements, proper dilution ratios, no chemical mixing
Application Method Spray equipment, even distribution, proper contact time
Worker Protection Gloves, masks, protective clothing, eye protection
Rinsing Protocol Minimum 3 rinse cycles, water quality testing, odor check

Safety Standards & Protocols

Worker safety and service quality are inseparable. We maintain strict safety protocols:

Confined Space Entry (Underground Tanks)

  • Oxygen level monitoring: Continuous air quality measurement
  • Ventilation equipment: Air blowers ensure fresh air circulation
  • Safety harnesses: Fall protection for deep tanks
  • Two-person teams: One inside, one outside for emergencies
  • Emergency procedures: Rescue plan and first aid readiness
  • Communication systems: Walkie-talkies for constant contact

Elevated Work (Overhead Tanks)

  • Professional ladders: Industrial-grade, secured properly
  • Safety ropes: Worker tied off at all times
  • Non-slip footwear: Prevents accidents on wet surfaces
  • Tool securing: Prevents dropped objects
  • Weather monitoring: No work during rain or high winds

Personal Protective Equipment (PPE)

All our technicians wear complete safety gear:

  • Waterproof boots: Steel-toed, anti-slip soles
  • Protective clothing: Waterproof coveralls
  • Chemical-resistant gloves: Nitrile or rubber
  • Safety goggles: Protect eyes from chemical splash
  • Respiratory protection: N95 masks or respirators when needed
  • Hard hats: For work in deep or overhead tanks
