How long can you keep tap water in the fridge?

In the brief guide, we are going to answer the question ‘How long can you keep tap water in the fridge’ with depth analysis of what safety measures to keep in mind when storing it.

How long can you keep tap water in the fridge?

The storage practices and methods used determine the life of tap water. Depending on this, the retention period can be one year or indefinitely.

Is it necessary to filter your tap water?

Tap water is generally safe to drink, and supporting your local public water utility is a wise and cost-effective decision. Filtration of tap water removes any chemicals used to kill bacteria, viruses, parasites, and fungus.

How do you keep tap water stored?

Directly fill bottles or jugs from the faucet. Cap each container tightly and label it with the words “Drinking Water” and the data stored. Keep sealed containers in a dark, dry, and cool location. If you haven’t used the stored water within six months, empty it from the containers and repeat steps 1 through 3 above.

How do you keep tap water for a long time?

Yes, you can keep tap water for a long time. If properly stored, it is safe to drink. However, storing water for more than 6 months is not advised. Bacterial growth can occur when water is stored for an extended period of time.

How long can water be kept before it spoils?

For starters, the length of time that drinking water can be safely stored varies from one day to indefinite depending on how the water is stored and how pure it is.

Clean water left in an open cup outdoors for 13 days is likely to be degraded (contaminated). Your tap water (assuming it’s safe to drink) is kept in an airtight container for up to 6 months or more; however, you should test the water and add a small amount of household bleach for cleaning (do not use bleach with air fresheners or perfume).

Pure water sealed in a food container will last at least two years if not more.

How long can water be stored in a 55-gallon drum?

Under the right conditions, potable water stored in a food-grade 55-gallon drum can be safely stored for up to a year or even longer. 

To safely store water in a 55-gallon drum or barrel for a year or longer, use a clean food-grade drum that is tightly sealed to keep out light and chemicals, is kept in a dark cool location away from concrete, and is not accessed improperly. 

Furthermore, if treated on a regular basis (roughly every 6 months) with the appropriate amount of household chlorine bleach or a water purifier, it can store for much longer; however, if at all possible, I replace my stored water every year.

Is it possible for stored water to deteriorate?

Water will not spoil if properly stored. The contamination that enters the water is what causes it to deteriorate. In theory, if you take the proper precautions, such as sealing and storing it so that bacteria or other contaminants do not get into it and cause it to go bad, your water could store and remain good indefinitely.

How to store water to keep It fresh?

  • Begin with clean, potable water.
  • Clean food-grade plastic, glass, enamel-lined metal, or fiberglass containers should be used.
  • Keep light and chemicals out by tightly closing the container (covering water storage with a tarp could be a good idea)
  • Store away from concrete, away from chemicals, or anything else that you don’t want to leach into the water, and in a dark, cool place.

How can you tell if your water has turned bad (been contaminated)?

  • If your water storage has an unusual odor, it could be contaminated.
  • Is hazy
  • A strange color has emerged.
  • It has green algae growing in it.
  • There are floaties.

Does drinking old water make you sick?

Drinking contaminated water can make you sick. However, getting sick is caused by bacteria, algae, and pathogens that get into the water, not the old water. So, getting sick from drinking stale water is determined more by how the water was originally stored and clean than by its age.

What are some ways to store water that can go wrong?

  • Contaminant leaking from the container into the water tank
  • Bacteria or algae  initially present in  water before it is stored in a tank
  • Improper access to the water tank
