Step 4: Treating the water
Treating the water in the tank is an essential step to ensure that the water is safe and free from contaminants. Here's why treating the water is necessary:
Explanation of why treating the water is necessary:
Even after cleaning and rinsing the tank, there may still be bacteria or other harmful contaminants in the water.
Treating the water helps to kill any remaining bacteria or other harmful contaminants and makes the water safe to use.
Types of water treatment methods:
Chlorination: Chlorine is commonly used to disinfect water. It is added to the water in a specific quantity and allowed to sit for a certain period of time to ensure that all bacteria and other harmful contaminants are killed.
Ultraviolet (UV) Treatment: UV light is used to kill bacteria and other harmful contaminants in the water. The water is passed through a UV chamber, where it is exposed to UV light, which kills all bacteria and other harmful contaminants.
Ozonation: Ozone gas is used to disinfect the water. The gas is bubbled through the water, which kills all bacteria and other harmful contaminants.
Instructions on how to treat the water:
Choose the method of water treatment that suits your needs.
Add the appropriate amount of treatment chemicals or equipment to the water as per the instructions.
Allow the treatment to sit for the recommended amount of time.
After the treatment period, test the water to ensure that all bacteria and other harmful contaminants have been removed.
By following these instructions and using the appropriate water treatment method, you can ensure that the water in your tank is safe and free from contaminants.
Rinse and Prepare the Tank Before Refilling
After cleaning, remove loosened dirt, sediment and cleaning residues from the tank. Rinse the internal surfaces thoroughly with appropriate clean water and drain the rinse water rather than allowing cleaning residues to remain in the storage tank.
If disinfection is required, use an appropriate method and follow the product instructions or relevant water-safety guidance. The tank should be ready for safe water storage before it is returned to normal use.
The goal is not simply to make the tank look clean, but to leave the storage space free from visible debris and unsuitable cleaning residues before refilling.
Step 5: Refilling the tank
Once you have treated the water, the final step is to refill the tank. Here's how to refill the tank:
How to refill the tank:
Close the valve to the outlet pipe.
Use a hose or bucket to fill the tank with water.
Once the tank is full, open the valve to the outlet pipe.
Recommended precautions to take while refilling the tank:
Before refilling the tank, make sure that all of the previous steps have been completed, including cleaning, rinsing, and treating the water.
Ensure that the water supply used for refilling the tank is clean and safe for drinking.
Avoid overfilling the tank, as this can cause the water to spill over and create a mess.
How to check the quality of the water after clean water tank:
After the tank has been refilled, check the quality of the water by testing it for bacteria or other harmful contaminants.
You can test the water using a water testing kit or by sending a sample to a water testing laboratory.
It is recommended to test the water periodically to ensure that it remains safe and free from contaminants.
By following these instructions and taking necessary precautions, you can refill your water tank with clean and safe water. Remember to periodically check the quality of the water to ensure that it remains safe for use.
How to Prevent Water Tank Contamination
Regular cleaning is only one part of maintaining a hygienic water-storage system. The tank should also be protected from sources of contamination between cleaning cycles.
Keep the tank properly covered and check that the lid is secure. Inspect the inlet, outlet, overflow and surrounding area periodically for damage, debris or other conditions that could allow contaminants to enter.
Avoid allowing insects, animals, dust, leaves or other foreign material to enter the tank. If stored water is intended for drinking, maintaining the cleanliness of the complete water-supply system is important because safe water can become contaminated again if storage conditions are poor.
Common Water Tank Cleaning Mistakes
A few common mistakes can reduce the effectiveness of water-tank cleaning:
Cleaning the tank but leaving sediment or sludge behind
Refilling the tank before cleaning residues have been properly removed
Ignoring the tank lid, inlet, overflow and surrounding area
Using cleaning chemicals without checking whether they are appropriate for the intended water use
Cleaning the tank but ignoring a continuing water-quality problem at the source
Forgetting to check the tank periodically after cleaning
Attempting to enter a large or difficult-to-access tank without appropriate safety measures
A clean-looking tank does not necessarily mean that the entire water-supply system is free from contamination. If water quality remains abnormal after cleaning, investigate the source and distribution system as well.
How Often Should You Clean a Water Tank?
The cleaning frequency of a water tank depends on the water source, storage conditions, visible sediment or deposits, and how the tank is maintained. For household tanks, regular inspection and periodic cleaning are important rather than waiting until the water becomes visibly dirty.
Some Indian government guidance recommends cleaning overhead tanks at least once every six months in institutional settings. For a household, the appropriate schedule can vary according to local conditions and the condition of the tank. If sediment, algae, unusual odour, discoloration or other contamination is noticed earlier, the tank should be inspected and cleaned as appropriate.
Keeping a simple record of the last cleaning date can also make routine maintenance easier to manage.
When Professional Cleaning May Be Appropriate
Professional cleaning may be appropriate when a tank is very large, difficult to access, heavily contaminated, structurally damaged or requires specialist equipment.
Professional assistance is also worth considering when the tank requires internal entry. Working inside a confined storage space can present safety risks and should not be treated as a routine household cleaning task.
If contamination is suspected after flooding, sewage exposure or another unusual event, the tank and water supply may require more than ordinary surface cleaning. In such situations, follow guidance from the relevant water or public-health authority before returning the tank to normal use.
