Is it Safe to Drink Old Water Storage?


In a situation that might lead to a water shortage, you may feel like storing water is a good and safe way to tackle the issue. However, there are many problems associated with keeping this water stored for extended periods. Even if it is for a couple of days and the water is tightly packed, it can still be unfit to consume. If you keep a glass of water near you overnight, most likely, it will change its taste because it absorbs some of the carbon dioxides in the air. Even with the carbon dioxide, the water is safe to drink, but the water loses its potency when the chlorine wears off. 

  1. What the water is stored in – If you buy all your water bottles from a shop, then it would be safer than the tap water; however, these bottles have life and, when used beyond a point, can lead to chemicals leaching into the water. You must be aware of the tank in which you store your water and also the water bottles. 
  2. The temperature where it is stored– The high temperature will make it easier for bacteria to grow and multiply. Water stored in the warmer areas of your home will make it more likely to be unfit for drinking. 
  3. How was the water purified before storage– Most of the water is purified before it even reaches you. This plays a crucial factor in determining how clean your water is. It is also important to know that your way of filtering the water is working well. If you have a filter at home, then make sure you service it and clean it regularly. 

Can You Test Water For Safety? 

You can spend money depending on your budget to buy a water testing kit. It could be as simple as a few strips that change color, or it could be a more advanced but small machine. 

Some More Tips For Storing Water Longer

Rotating your water frequently is a good way to keep the water fresh. Keeping that water in a cool dark area will be ideal so that no bacteria can grow in it because the bacteria can multiply faster in warmer areas. Having good quality pipes can also be crucial; if the quality is good, it is less likely to leak contaminants into the water. You can use water purifying drops too. If you do fill water into your own bottles, make sure you drink it preferably within a twenty-four-hour period. Beyond that, it is likely to get more bacteria growing in it even if it is closed properly. 

Drinking Water From An open Container

Even closed containers can have harmful bacteria growing in them, but it is even worse when it is open for a long time. You have all kinds of dust, insects, etc., that can get into it and contaminate your water, which can make you very sick. If you do not have a cap to seal the bottle tight, then even a lid is a better option than simply leaving it open. 

Drinking Water From The Bottle

As long as you are not keeping the water in that bottle for too long, it is quite safe to drink from it. When your mouth touches the bottle, then saliva and skin cells from your lips can get into the water. This can speed the process of the water becoming unfit for consumption. It is always safer if you drink water directly from a glass. Also, remember that the expiration date on the packaged water is usually for the bottle, so it is a good idea if you get rid of the bottle after that. 

Boiling Water

According to many people, boiling water is still the best way to go because even though you have packaged water or RO systems, these may kill bacteria and remove many essential minerals present in the water. When you boil the water, it kills off bacteria, but it maintains the minerals in the water, which can give a lot of health benefits. RO systems are okay for some extreme situations but not for everyday use because RO systems wastewater after it is filtered off.


Your body demands a lot of water every day, but it is important to keep the tips mentioned above in mind and ensure that the water is safe to drink. Keep only as much water as you need outside, and avoid touching your mouth to the bottle or leaving that bottle with water for long periods. Even though it is important to make sure the water you drink is clean, try not to waste it because many people do not get clean water to drink every day. Use the water you have wisely and be smart about storing it because it can have very lasting long-term health risks if you don’t store it properly.
