Keeping your overhead water tank clean is crucial for ensuring safe and healthy drinking water for your household. Regular cleaning prevents the buildup of algae, sediment, and bacteria, which can contaminate your water supply. This guide will walk you through the essential steps for effectively cleaning your overhead water tank.
Why Regular Overhead Water Tank Cleaning is Essential
Overhead water tanks, often made of plastic or concrete, can become breeding grounds for harmful microorganisms if not maintained. Sediment can settle at the bottom, reducing water quality and potentially clogging pipes. Algae growth can also occur, leading to unpleasant odors and tastes.
The Risks of a Dirty Water Tank
- Health Hazards: Contaminated water can cause various waterborne diseases like cholera, typhoid, and dysentery.
- Reduced Water Quality: Sediment and debris affect the clarity and taste of your water.
- Pipe Damage: Accumulated sludge can corrode pipes over time.
- Unpleasant Odors: Bacterial growth often results in foul smells.
Step-by-Step Guide to Cleaning Your Overhead Water Tank
Cleaning your water tank might seem daunting, but following these steps will make the process manageable and effective. Remember to prioritize safety throughout the entire cleaning process.
Preparation is Key
Before you begin, gather all necessary supplies. This includes a sturdy ladder, gloves, a face mask, cleaning brushes (long-handled is helpful), a disinfectant (like chlorine bleach or a specialized tank cleaner), water buckets, and old clothes.
- Turn Off the Water Supply: Locate the main inlet valve to your tank and shut it off completely. This prevents more water from entering during the cleaning process.
- Drain the Tank: Open all taps in your house to drain as much water as possible. For the remaining water in the tank, you can use a submersible pump or a hose to siphon it out. Ensure all water is removed from the bottom.
- Open the Tank: Carefully open the manhole cover of the tank. Ensure it’s safe to access.
The Cleaning Process
With the tank empty and prepared, it’s time for the actual cleaning.
- Scrub the Interior: Use your brushes to scrub the inner walls and floor of the tank. Pay close attention to any visible sludge, slime, or algae. A stiff-bristled brush is effective for removing stubborn deposits.
- Rinse Thoroughly: After scrubbing, rinse the entire interior of the tank with clean water. This removes loosened debris and any remaining cleaning agents.
- Disinfect the Tank: Prepare a disinfecting solution. A common method is to mix 1 liter of liquid chlorine bleach with 10 liters of water. Pour this solution into the tank and let it sit for at least 30 minutes to kill any remaining bacteria or viruses.
- Final Rinse and Drain: After the disinfectant has worked, drain the tank completely again. Rinse the tank multiple times with fresh water to ensure all traces of the disinfectant are removed. Open all taps again to flush the pipes.
Post-Cleaning Checks
Once the tank is clean and refilled, it’s important to ensure everything is functioning correctly.
- Check for Leaks: Inspect the tank and its connections for any signs of leaks.
- Refill and Reopen: Once you are satisfied, close the drain valve and reopen the main inlet valve to refill the tank.
- Flush Taps: Run water through all your taps for a few minutes to flush out any residual air or cleaning solution from the pipes.
How Often Should You Clean Your Overhead Water Tank?
The frequency of cleaning depends on several factors, including the water source quality, local environmental conditions, and the tank’s material. Generally, it is recommended to clean your overhead water tank every 6 to 12 months.
Factors Influencing Cleaning Frequency
- Water Source: If your water comes from a well or a source prone to contamination, more frequent cleaning might be necessary.
- Environmental Dust: Areas with high dust or pollution may require more regular cleaning.
- Tank Material: Older concrete tanks might be more susceptible to leakage and contamination than newer plastic ones.
Common Issues and How to Address Them
Sometimes, you might encounter specific problems during or after cleaning.
Mildew and Mold Growth
If you notice mildew or mold, ensure the tank is thoroughly disinfected. Proper ventilation around the tank can also help prevent recurrence.
Persistent Odors or Tastes
If odors or tastes persist after cleaning, it might indicate a more significant contamination issue or a problem with the water source itself. Consider re-disinfecting or consulting a water quality professional.
Sediment Buildup
Heavy sediment buildup suggests your water source has a lot of particulate matter. Installing a sediment filter on your incoming water line can help reduce the amount of debris entering the tank.
When to Call a Professional
While DIY cleaning is feasible, there are situations where hiring a professional water tank cleaning service is advisable. This includes:
- Very large tanks that are difficult to access or manage alone.
- If you suspect significant structural damage or contamination.
- If you are uncomfortable performing the cleaning yourself due to physical limitations or safety concerns.
Professionals have specialized equipment and expertise to ensure a thorough and safe cleaning.

Afterward, drain the tank completely and rinse it multiple times with fresh water to remove all traces of the disinfectant.
### What is the best way to remove algae from a water tank?
The best way to remove algae is by physically scrubbing the tank walls with a stiff brush after draining it. Once the visible algae are removed, proceed with disinfecting the tank using a chlorine bleach solution. Regular cleaning and ensuring the tank is covered properly will prevent algae growth in the future.
### Can I use soap to clean my overhead water tank?
It is not recommended to use regular soap for cleaning overhead water tanks that store drinking water. Soaps can leave residues that are difficult to rinse completely and may affect the water’s taste and safety. Instead, use a mild disinfectant like chlorine bleach diluted with water, or specialized tank cleaning solutions.
### How long does it take to clean an overhead water tank?
The entire process of cleaning an overhead water tank, from preparation to refilling, typically takes 3 to 5 hours. This includes draining the tank, scrubbing, disinfecting, rinsing, and refilling. The exact time can vary depending on the tank’s size, the level of dirt, and the efficiency of the cleaning process.
