How to do a basic Cement Tank Cleaning safety check and quick fixes

Quick answer (read this first)

• Regularly inspect the tank exterior for cracks or leaks.
• Ensure the tank lid is always securely fastened.
• Address minor external issues promptly to prevent bigger problems.
• Never attempt to enter the water tank yourself.

Safety first

• NEVER enter a water tank; suffocation and drowning are extreme risks.
• Always work with a helper present to assist in emergencies.
• Wear gloves and a mask, especially when dealing with stagnant water or dust.
• Ensure the area around the tank is well-ventilated.
• Do not use electrical tools near water unless absolutely necessary and with professional guidance.

Tools you may need

• Flashlight
• Long stick or pole (for remote inspection, do NOT enter the tank)
• Rubber gloves
• Stiff brush or scrubber (for exterior)
• Small bucket and sponge
• Waterproof sealing compound (for minor external cracks)
• Basic wrench/screwdriver (for lid fasteners)

Step-by-step

Step 1

Clear the Area: Ensure the tank surroundings are free of debris and obstructions. This allows for safe access and better visibility during inspection.

Step 2

Inspect the Exterior: Carefully examine the tank’s outer walls and base for any visible cracks, seepage, or damp patches. Note any areas of concern.

Step 3

Check the Lid Security: Verify that the tank lid is properly fitted and securely fastened to prevent contaminants, insects, and pests from entering. Tighten or replace loose fasteners.

Step 4

Look for Leakage Signs: Inspect the ground around the tank for any puddles or consistent dampness, which may indicate a leak. Trace any water trails back to their source if possible.

Step 5

Assess Inlet/Outlet Pipes: Examine the connections of pipes entering and leaving the tank for any signs of corrosion, damage, or minor leaks. Gently tighten any visibly loose pipe fittings.

Step 6

Remove Exterior Growth: Gently scrub away any moss, algae, or dirt accumulating on the tank’s exterior or around the lid with a brush and plain water. Maintain a clean exterior.

Step 7

Perform Minor External Patching: For small, hairline cracks on the tank’s exterior, apply a suitable waterproof sealing compound as per product instructions. This is for surface-level issues only.

Common mistakes

• Attempting to enter the water tank for any reason.
• Ignoring small cracks or seepage, allowing them to worsen over time.
• Using harsh, unapproved chemicals for cleaning the exterior without proper safety gear.
• Leaving the tank lid unsecured, leading to water contamination.
• Not regularly checking the tank’s exterior for signs of damage.

When to call a professional

• If you notice large cracks, structural damage, or bulging in the tank walls.
• For persistent leaks that are not resolved by simple external patching.
• If there’s significant internal contamination, foul odors, or changes in water quality.
• For any required internal repairs, deep cleaning, or structural assessments.
• If you are unsure about the cause or solution of a tank problem, especially involving water quality.
