Tips for Maintaining the Hygiene of Your Overhead Water Tank

Water tank

Almost every house owner in India installs a water tank on their rooftops. However, the water quality and durability of water tanks vary from one brand to another. Proper maintenance of the tank is the reason behind this. A premium quality water tank can last for decades if proper attention is given to its maintenance. However, many people ignore this aspect, which ultimately requires them to install a new tank. Not only this, water stored in tanks that are not maintained regularly, causes multiple health issues.

If you want your water tank to last longer, it is important to follow a timely maintenance routine.

Steps of Water Tank Maintenance

You can either hire a professional cleaning team or personally execute all the processes for maintaining the quality of your tank. In both situations, you must be aware of the steps of maintenance to ensure increased longevity of the tank. These steps include:

  • Inspecting Lids

The lid is crucial for preventing insects and other atmospheric contaminants from entering the tank. Regular inspection of the lid helps ensure its strength and keeps the water safe for consumption. During the inspection, you must check that it closes properly without leaving even a slight gap.

  • Outlet and Inlet Pipes Inspection

The areas where inlet and outlet pipes connect to the tank need to be free of cracks or leakage to supply hygienic water and save water by preventing leakage. Moreover, if leaks occur from these points, they can damage the roof area. Therefore, you must take steps to fix even a minute sign of a crack or leak near the inlet and outlet pipe connection.

  • Look for Cracks on Tank Surface

Water tanks that are exposed to direct sunlight can sometimes develop cracks. However, with proper maintenance procedures, you can fix the early signs of such damage. This helps in increasing the water tank’s longevity and saving huge sums of money in the long run.

  • Cover the Air Exhaust and Overflow Pipes

These pipes are meant to let out air and excess water during the water-filling process. However, sometimes these pipes become an inlet passage for contaminants. Therefore, to maintain the cleanliness of the water, you must routinely check the mesh covering these pipes for large holes.

Cleaning the Insides of the Water Tank

Cleaning the tank once every year is essential to maintain the hygiene of the water and remove sludges that develop in the bottom area. Therefore, apart from external inspection and repair, you must pay attention to cleaning the inside surface of the overhead water tanks.

You need a hard brush, detergent, and a water jet for cleaning the tank. In addition, it is vital to follow the below-mentioned steps of cleaning to avoid inconveniences.

1. Empty the water tank

The first step to cleaning the water tank involves emptying the tank by draining stored water. To avoid water shortage in the household during the cleaning process, you can store the water in buckets or other storage materials. To make the cleaning process convenient, you must use a sludge pump to drain the thick layers.

 2. Scrub the tank

Once the tank is empty, you need to scrub its wall and floor manually. This process removes the fungus, stains, sediments, and dirt from the tank. However, during this process, consider wearing a mask to avoid infection. Once you finish scrubbing, use a water jet to clean the wall properly.

3. Vacuum Clean the Sediments

As the dirt and sediments settle on the tank floor, use a vacuum cleaner to drain them. If the sediments are thick, they may stick to the vacuum cleaner passage. Therefore, you must be extra cautious to keep the vacuum clean during this step.

4. Disinfect the Tank

You need to use a liquid bleach or antibacterial solution to kill germs and microbes in the tank. Once you spray the liquid in the tank, wash the surface with clean water and drain all the liquid through taps and a vacuum cleaner. You can ask the water tank supplier about which disinfectant you can use for cleaning purposes.

5. Dry the Empty Tank

Lastly, you need to dry the washed tank properly so that the water left from the cleaning process evaporates properly. Afterwards, you can refill the tank with clean water for household utility.


Water tank maintenance is an essential part of maintaining the health of your family. Moreover, it saves your house structure from damage caused by water leakages. Therefore, ensure to inspect the inlet/outlet pipes, lids, cracks, and water overflows. Ensure that while cleaning the water tank, you follow all the steps mentioned in this blog. You must devote significant time to looking after your water tank and save money in the long run.
