All About Water Tank & Sump Cleaning

Maintaining clean water storage is essential for health and hygiene. Over time, water tanks and sumps accumulate dirt, algae, bacteria, and sediments that can compromise water quality. Whether it’s overhead tanks or underground sumps, regular cleaning ensures a safe water supply for your home and business. At HomeTriangle, we offer expert water tank and sump cleaning services that eliminate contaminants and ensure your water remains fresh and safe.

Why Regular Water Tank & Sump Cleaning is Important

Water stored in tanks and sumps is vulnerable to contamination due to environmental factors, stagnant water, and poor maintenance. If left unchecked, these contaminants can cause:

  • Algae and bacterial growth
  • Bad odor and taste
  • Waterborne illnesses
  • Sediment buildup, clogging pipes and taps
  • Corrosion or leaks in the tank

Regular cleaning eliminates these risks and ensures that the stored water is suitable for drinking, bathing, cooking, and other uses.

Our Water Tank & Sump Cleaning Process

At HomeTriangle, we follow a step-by-step cleaning process to ensure complete hygiene:

  1. Inspection & Draining

    • The team inspects the tank/sump to identify contamination or damage.
    • Water is completely drained to prepare the surface for cleaning.
  2. Scrubbing and Removal of Deposits

    • Walls, corners, and the base are scrubbed to remove algae, sediment, and other deposits.
    • Special tools ensure even hard-to-reach areas are cleaned.
  3. Pressure Washing

    • High-pressure jets are used to wash away dirt and stubborn residues.
    • This process also prevents microbial growth.
  4. Vacuuming Sludge & Residues

    • A suction pump removes sludge and debris from the bottom of the tank.
    • This ensures thorough cleaning without leftover contaminants.
  5. Disinfection with Eco-Friendly Agents

    • We use food-grade, non-toxic disinfectants to kill bacteria and algae.
    • These agents are safe for both drinking water tanks and non-drinking water storage.
  6. Refilling & Testing

    • Once cleaned, the tank is refilled, and water quality is tested to ensure it meets safety standards.

Types of Water Tanks and Sumps We Clean

We provide comprehensive cleaning services for:

  • Overhead Water Tanks (Plastic, Metal, Sintex, RCC)
  • Underground Sumps
  • Residential, Commercial, and Industrial Tanks
  • Drinking Water Storage Tanks
  • Firefighting and Rainwater Harvesting Tanks

Signs Your Water Tank or Sump Needs Cleaning

  • Foul smell from the water
  • Visible dirt or algae on the walls
  • Cloudy or discolored water
  • Reduced water pressure from taps
  • Water tastes metallic or stale
  • Increase in waterborne illnesses

If you notice any of these signs, it’s time to schedule a cleaning session.

  • Overhead Water Tanks: Every 6 months
  • Underground Sumps: At least once a year
