Are plastic water tanks safe?

Both potable and non-potable plastic water storage tanks are very safe to handle. Slightly more care has to be taken when handling non-potable water, since it is not sanitised as much and there is a higher risk of infectious contamination. Algae and bacteria are the enemies to look out for when storing water in plastic tanks, though they afflict tanks made of other materials just as much. In potable water stores, the presence of algae in the water or on the walls can cause severe illness for those who drink it. Proper filtration of drinking water is crucial and must be taken seriously. On the other hand, since our water tanks are above-ground based, there is much lower risk of arsenic or fluorosis contamination compared to groundwater supply chains.
