Common Contaminants in Concrete Water Tanks
Concrete water tanks are strong and reliable, but over time, they can collect different types of contaminants. Knowing what these are is key to keeping your water safe and clean. In Dubai, where the heat is intense and dust is common, cleaning your water tank is even more important. Here are some of the most common things that can contaminate your concrete water tank:
Algae and Bacteria: The warm, still conditions inside water tanks are perfect for algae and bacteria to grow. Algae love damp areas, especially in tanks with little sunlight or poor airflow. Harmful bacteria, like Legionella, can also develop and pose serious health risks if not cleaned regularly.
Sediment and Debris: Over time, dirt and dust can settle in the tank, leading to sediment build-up. This can cause the water to change colour and develop unpleasant smells. If left unchecked, it can also block the water distribution system, creating clogs.
Mineral Deposits: In Dubai, the water is often hard, meaning it contains high amounts of minerals like calcium and magnesium. When water sits in the tank or evaporates, these minerals can leave deposits that not only affect the water’s taste but can also damage the tank over time.
Organic Matter: Leaves, twigs, and plant matter can enter your tank through open vents or cracks. As they break down, they can create a breeding ground for harmful microorganisms and make the water taste or smell bad.
Insects and Rodents: If your tank isn’t sealed properly, insects like mosquitoes and even rodents can get in. They bring bacteria and pathogens that can contaminate the water. Their waste can also make the water unsafe.
Chemical Contaminants: Sometimes, chemicals from nearby industrial activities or construction sites can seep into water tanks. These chemicals are dangerous and can seriously affect the water’s safety.
To avoid these contaminants, regular cleaning and maintenance of your concrete water tank is essential. By understanding what risks are involved, you can keep your water safe and clean for your home or business.
Step-by-Step Guide: How to Clean an RCC Water Tank

Safety First: Before you start, put on gloves, safety goggles, and a mask. These will protect you from dust, debris, and any chemicals used during the cleaning.
Turn Off Water Supply: Switch off the water supply to the tank to stop fresh water from coming in while you clean.
Empty the Tank: Drain all the water from the tank. You can use a pump or let gravity do the work. If the tank is big, you might want to hire a professional to handle this.
Inspect the Tank
Visual Check: Once the tank is empty, look inside carefully for cracks, leaks, or any damage. Fix any issues before continuing.
Look for Stains and Deposits: Check for stains, algae, mineral deposits, and sediment on the tank’s walls and floor.
Scrub the Tank Interior
Remove Loose Debris: Use a broom or brush to sweep out dirt and debris from the bottom of the tank.
Scrub the Walls: With a long brush, scrub the tank walls to remove mineral deposits, algae, and dirt. You can use a mild detergent or water-based cleaner, but avoid harsh chemicals that could damage the tank.
Focus on Problem Areas: Spend extra time on areas with visible algae or bacteria, as these can affect the water quality.
Disinfection and Sanitisation
Prepare a Disinfectant Solution: Mix a 5% chlorine bleach solution with water. This will help kill harmful bacteria and pathogens.
Apply the Solution: Using a clean cloth or mop spread the disinfectant across all the tank surfaces, including the walls, corners, and floor. Let it sit for at least 30 minutes.
Rinse Thoroughly: After waiting, rinse the tank with clean water to remove any leftover chemicals. Make sure no disinfectant remains, as it could harm the water quality.

Clean the Inlet and Outlet Pipes: Use a brush or pipe cleaner to remove any build-up or blockages from the inlet and outlet pipes. These parts are often overlooked but are important for ensuring clean water flow.
Inspect Valves: Check the valves for damage or leaks. Replace any faulty ones to keep the system clean and secure.
Refill the Tank
Allow the Tank to Dry: Let the tank dry out completely before refilling, especially if there’s any remaining moisture.
Refill the Tank: Once it’s dry, refill the tank with fresh water. Open the valves carefully and keep an eye on the water level to make sure everything is working properly.
Final Inspection and Maintenance Tips
Final Check: After refilling, look for any leaks or irregular water flow. Make sure the cleaning didn’t cause any new problems.
Schedule Regular Cleaning: Plan to clean your RCC water tank every 6 to 12 months, depending on water use and the environment. This helps keep your water fresh and your tank in good condition.
By following this simple guide, your RCC water tank will be clean, disinfected, and ready for use. Regular cleaning helps maintain water quality and prevent harmful build-up. If you’re unsure about any part of the process, you can always hire tank cleaners to do the job safely and efficiently.
Best Practices for Concrete Water Tank Maintenance
Maintaining an RCC (Reinforced Cement Concrete) water tank is crucial for ensuring its longevity, preserving water quality, and preventing damage. Proper maintenance reduces the risk of contamination, protects the tank structure, and ensures a safe water supply. Below are some essential best practices for maintaining your concrete water tank:
Regular Cleaning
- Clean the Tank Annually: Schedule a comprehensive cleaning of your concrete water tank at least once a year. This helps to remove sediment, algae, mineral deposits, and other contaminants that can compromise water quality.
- Use Safe Cleaning Agents: Opt for non-toxic cleaning agents such as chlorine or vinegar. Avoid harsh chemicals that could damage the tank or pollute the water.
- Drain Completely Before Cleaning: Always drain the tank fully before cleaning to access all surfaces, corners, and the tank floor properly.
Inspect for Cracks and Leaks
- Check for Structural Damage: Regularly inspect the tank for cracks, leaks, or any signs of wear. Extreme weather conditions can accelerate the deterioration of concrete tanks. Cracks can let in contaminants or cause water loss.
- Repair Immediately: Fix any cracks or leaks promptly. Use waterproof sealants or hire professionals to address significant damage. Unrepaired cracks can worsen, leading to more expensive repairs or water contamination.
Maintain Proper Tank Sealing
- Seal Openings Properly: Ensure that the tank’s inlet, outlet, and ventilation openings are sealed tightly when not in use. This prevents debris, dust, and pests from entering the tank.
