How to disinfect your water tank

Initial preparations

You need to do some preparations before you can disinfect your water tank. The first step of preparation is that you have to drain all the water out of the tank. Additionally, we suggest that you store some water in external containers as the entire process of disinfecting your tank might take a few hours.  Moreover, only trained personnel with the proper equipment and protective gear should enter your water tank.

Measure the volume of the tank

The volume of a water tank has a very important role in the entire cleaning process.  You need to measure the volume to determine the exact amount of disinfectant that you will need to clean the tank.  For example, if you add more disinfectant then, the water tank might become unusable for a long time. Additionally, you must remember that the shape of the tank will also play a vital role in determining the exact amount of disinfectant that you will need.

Adding disinfectants to the water tank

Now that you have finished measuring the amount, it is time to add the disinfectant to the tank. Firstly, you have to fill a quarter of your tank with treated portable water. After this, you have to mix the household chlorine bleach to the water.  We can use water tank insulation covers also which can increase tank life. Additionally, you must ensure that you mix the bleach thoroughly to create an even solution. The final step is to close the water tank and let this solution sit in the tank for at least 12 hours.  After 12 hours, you have to drain this solution properly and ensure that not a single drop of it remains inside the tank.

How to clean the tank

Now that you have finished disinfecting the tank, you must clean the tank properly. A clean tank not only prevents all sorts of microbial growth but also has a longer lifespan.

Scrub the walls of the tank

The first step to cleaning your water tank is to scrub its outer and inner walls thoroughly. For this purpose, you can use a stiff brush as a sweeper or a high-pressure water jet. Additionally, you can create a mixture of detergent and hot water to properly clean the inner walls of the tank.  You must have proper protective gear before entering the water tank.

Thorough cleaning

A thorough cleaning of the tank will ensure that there is no dirt or remains of the chemicals in the corners of the tank. In case you don’t clean the corners that have chemical remains, the water tank might have a bad odor and the water from the tank might taste bad.  After the cleaning process is completed, we recommend that you keep the lid of the tank open for a few hours to allow fresh air circulation inside the tank.

Drain, Flush, and Refill

Cleaning the water tank won’t be effective if the pipes and water distributions system isn’t cleaned as well. So, we recommend that you flush the pipes thoroughly with a bleach solution until they are completely clean. Additionally, the water tank must also be flushed with fresh water a couple of times to ensure that there are no remains of the chemical inside the tank. After this process is completed, your water tank is completely clean and it is ready to be used again. So, you can refill the tank and it will start serving clean drinking water to the entire building.
