How to Clean a Concrete Water Tank?

Published in Water Tank Maintenance 2 mins read

To clean a concrete water tank, you'll need a bleach solution, a stiff brush, and plenty of clean water. Here's the process:

Steps to Clean Your Concrete Water Tank

  1. Prepare the Cleaning Solution: In a bucket, mix 10 gallons of water with one cup of unscented household liquid bleach (ensure the bleach is 5% to 8.25% strength).

  2. Scrub the Tank: Using a stiff brush, thoroughly scrub the entire inside surface of the concrete water tank. Pay close attention to areas with visible buildup or staining.

  3. Rinse Thoroughly: Rinse the tank repeatedly with clean water to remove all traces of the bleach solution. Ensure no bleach residue remains, as this could contaminate your water supply. You may need to rinse several times to achieve this.

Important Considerations:

  • Safety: Always wear gloves and eye protection when working with bleach. Ensure adequate ventilation.
  • Water Source: If possible, use a pressure washer for rinsing to improve efficiency.
  • Disposal: Dispose of the used cleaning solution responsibly. Check local regulations for proper disposal methods.
  • Tank Size: Adjust the bleach solution proportionally based on the size of your tank.
  • Frequency: The frequency of cleaning depends on water source and usage. Inspect regularly and clean as needed.
