importance of cleaning the water tank

Unclean water is a habitat for germs

When you do not clean your water container at regular intervals, it builds up impurities in water leading to contamination. Impure water holds different kinds of germs, bacteria, and viruses responsible for health problems later on. Contaminated water can give birth to diseases such as dysentery, cholera, gastro, etc. For a long time, a tank left unclean becomes unfit for storing water and is also difficult to clean. Therefore, do not take the cleaning of your rooftop and water tank lightly. 

Cleaning of the tank affects water filtration system

Water filtration comes handy in removing harmful germs and bacteria. You have to ensure the cleanliness of the water storage tank for greater efficiency of the filtration system. For 100% efficiency of the filtration system, you have to maintain your water tank’s purity. Although water purifiers remove dirt and certain impurities from water, sanitation makes it germfree. 

Consequences of using unhealthy water

Unhealthy water is among the leading causes of death throughout the world. Death due to drinking unhealthy water comes after the deaths from the consumption of cigarette smoking. Many people do not take the cleanliness of the water storage area seriously. Such negligence can prove fatal and cause serious health issues. Many people often believe that they drink healthy water as they do not use tank water for drinking purposes. But, while brushing, gargling, bathing, washing, etc. the tank water goes into the human body. Therefore, you must take care of the water tanks as well to keep yourself healthy. 

Risks involved

Stagnant and unclean water also carries the potential risk of spreading deadly diseases, such as malaria and dengue. Also, stagnation is common in water tanks, and therefore you must disinfect your water tank regularly. A tank that is not cleaned for a while will start developing rust, sediment, and silt that will further cause deadly infections. 

Things to keep in mind before you start the cleaning process

Be aware of the precautions as you are looking to cleaning your home tank. 

  • Close or inlet supply valves of the tank. Your tank might have inlet valves from a submersible pump, bore motor, etc. Close these before the cleaning process. 
  • Check with the plumber to assess any risks before you start cleaning. 
  • Before you get into the tank to clean it thoroughly, make sure you disinfect it before getting inside. 
  • Do not access your submersible pump while you are cleaning the tank.
  • Cleaning the tank will require you to de-water the tank on your roof. Hence, your roof’s drainage system needs to be in proper condition and not clogged to ensure no flooding on your roof. 
  • If the tank supplies water to a large community, rather than a single-family, ensure that all occupants are made aware of the cleaning process. Hence, no one accesses the water supply. 
  • It is important to check if your tank’s floating valves and the tank’s closing lid are working perfectly fine. In case you are not sure, ask the cleaning team for the same. 
  • You might experience the issue of water not coming through some faucets of your house after a tank cleaning process. You will see that this happens as some debris or tank discharge might get stuck in the aerators. Clean the aerators for a thorough supply of water in your house. 
  • Remember to open the inlet valves of the water tank that you closed before the cleaning process. 

How to clean the water tank?

  • Empty your water tank and take a picture of the empty for the logbook.
  • Enter the tank only in the presence of two technicians and as per regulations of confined spaces. 
  • Now, manually scrape off all tank scaling and the internal surface. Then use a wet vacuum to vacuum the tank from inside. With duly note of every condition of the tank, dirt and debris should be removed. 
  • The tank should be filled again, and issues such as leakage, etc. should be noted. 
  • You can also purify the water using chlorine as needed by considering the pH of the water.
