How To Make Safe Water

Health & Wellness

According to NASA, about 71% of the Earth’s surface is covered by water. This includes oceans, vapour, rivers and lakes, glaciers, and the moisture in the ground. Despite this abundance of water, the amount of safe water is incredibly minimal by comparison. For this reason, it is important to disinfect water before trying to drink it, to ensure there’s no harmful bacteria in it that could make those who drink it ill. 

This article will cover a few methods you could use to make safe water, and discuss potable water tanks. Establishing what they are, what they’re used for, and maintenance they require to ensure safe water. 


Boiling water is one of the easiest ways to disinfect it. The bacteria which may be living in it, including viruses and parasites, cannot survive in such challenging conditions. Therefore, boiling the water for at least a minute will completely iradicate all the bacteria, disinfect the water and make the water safe to drink. Ensure to store your disinfected water in water-tight and sanitised containers, so as not to reintroduce bacteria to the water after boiling. 


When ingested in large quantities, bleach can be fatal. But incredibly small amounts of low-concentrated disinfectants can be harmless when measured correctly. Unscented chlorine black, idodine, or chlorine dioxide tablets will kill most harmful viruses and bacteria, but these methods aren’t as effective as boiling water.

It should be noted that water disinfection will not make water that contains harmful chemicals drinkable. These methods only make safe water that was previously infected by bacterial microorganisms. 

The general rules are that for every litre of water, 0.1 ml of bleach should be added. And if the water is cloudy, murky, coloured or very cold, twice the amount of bleach should be used. Additionally, only bleach with a 5%-9% concentration of sodium hypochlorite should be used with these measurements, else the bleach itself becomes toxic.

If your bleach is of 1% concentration of sodium hypochlorite, the measurements to disinfect water become greater. For example, for one litre of water, there should be 10 drops of bleach. 

The mixture should be combined well and left to sit for at least 30 minutes before consumption, to ensure the bleach is fully dispersed in the water. 

Chemical tablets should be used in exact accordance with the manufacturer recommendations, as this will vary. Some steps you take with one brand may be completely different with another, and could result in higher water toxicity. 

Potable Water Tanks

Potable water tanks are used in sectors across industries to safely store drinking water. Maintaining the safety of this water is absolutely essential, as any unintentional infestations of bacteria can create a lot of trouble for the businesses that use it. The best way to ensure your potable water tank keeps your water sanitary, is to conduct bi-annual maintenance. By doing so, you can quickly identify any problems with the tank, or the build up of natural sediment and algae that may interfere with the quality of your water. 

Potable water tank lining can help to protect your tank from cracks and leaks which can allow bacteria to infiltrate your tank. These eventualities can not only lead to the overall condition of your water tank decreasing, but also your water becoming dirty and undrinkable. For this reason, one of the best ways to make safe water is to ensure your water tank is in the best condition. 


There are many ways to make safe water if you have the means to do so, and you should endeavour to ensure your water is always safe before drinking it. This generally isn’t a problem for water that comes from mains pipes, but when it comes to your own personal water supply, you should always endeavour to disinfect it before drinking.
