How Can You Prevent Contamination of Water Stored in Water Tanks?

A plastic water storage tank serves as the primary water supply for many of us, providing clean water for drinking and other essential uses. And therefore getting the purest form of water is everyone’s primary concern. But as we all know, nowadays, there are many water-borne diseases due to the widespread issue of water pollution. As a result, each consumer should know the water’s purity before using a plastic water storage tank. Nevertheless, for this exact reason, let’s talk about the options available for preventing water contamination in residential or business water storage tanks.


Ways to Prevent Contamination of Water Stored in Water Tanks

To prevent water contamination, it is advisable to know about the water source and how can your water tank protect the water. Knowing how to prevent contamination of the water stored in tanks is necessary. The ways you can use to prevent contamination of water stored in water tanks are as follows:

  1. Cleaning the Catchment Areas 

    It is advisable to keep your catchment area neat and clean. You can make sure that there are no shrubs, broken branches, etc., near your catchment point. When collecting water from your roof or a stream near your home, it would be best to check that the area is neat.Many times, the point from where you are collecting your water might turn into an entry point for insects, dirt, etc., which might result in water contamination. Hence, keeping the area around your collecting point clean is necessary.

    You can evade collecting water from roofs that are painted freshly because the paint might blend with water and contaminate your stored water. Generally, paints may contain toxic chemicals, resulting in water contamination and making the water unfit for use.

  2. Cleaning the Water Tank 

    It is advisable to clean a water tank at least twice or thrice in one year. As time passes, oils, debris, and other contaminants start depositing in the tank. They settle at the bottom of the water tank and get attached to the inner walls of the water tank. The dirt enters and settles at the bottom of the water tank, becomes a breeding ground for insects and mosquitoes, and makes the water unfit for use.Therefore, cleaning, scrubbing, and draining the remaining water at the bottom is essential. You can expose the water tank to the sunrays to destroy the remaining microorganisms and refill the water once the tank gets air-dried.

  3. Installing Filtrating Points 

    There’s a possibility that debris and organisms can flow into the water tank through the point between the water tank and the supply point. Excessive flow of minute debris might get mixed and result in water contamination. Hence, it is necessary to install screening filtering points at the inlet and along the water pipes to prevent contamination.Installing screening and filtering points can decrease the requirement of cleaning the water tank frequently, and you can simply replace the filters. Filtering aid in decreasing the debris flow into the tank that might result in water contamination. You can effortlessly clean the miniature particles that might pass through hassle-free.

  4. Disinfecting Drinking Water 

    Rainwater is always a good source of clean water, but if you have any doubts, it’s advised to disinfect water if it is meant for drinking. If you collect rainwater from roofs, it is advisable to be more careful with disinfection because some might leave waste on rooftops. Thus, to stay on the safer side it’s recommended to disinfect water with chlorination tablets. The best part about chlorination is that these tablets are tasteless, hence they won’t change the taste of the water.The other methods you can use to disinfect water are osmosis and distillation, which ensure that you get clean water for drinking. Disinfecting stored water in a tank will restrict the growth of germs and water contamination, thus, making it fit for indoor use.



A water storage tank is a beneficial part of every household. A water tank for storing water can aid in reducing water costs and assure users of a consistent water supply if you face any water scarcity problem. Before purchasing a water tank, it is advisable to take a good look at the water tank price list.

Maintaining hygiene and preventing contamination of the stored water is as essential as buying a good water tank. Purchasing a layered water tank instead of buying a water tank without any layers is a good option because layered water tanks will prevent the growth of algae. You can opt to purchase a 4 layer water tank. It is the most preferred water tank for residential areas. So, once you have made your decision on a water storage tank, ensure that you keep the tank clean and tidy to ensure a consistent clean water supply.
