In this short article, we will provide an answer to the question “How long can you keep tap water in the fridge?” and the information on storing tap and filtered water.

How long can you keep tap water in the fridge?

You may extend the shelf life of tap water by following proper storage methods and procedures. Depending on the circumstances, the shelf life could be one year or indefinite.

It also depends on the purity of the tap water as well as the temperature at which it is kept in the storage container. On a hot summer day, clean water left outside at room temperature will go bad in 1 to 3 days, depending on the temperature.

When you acquire water from the faucet, however, put it in a container that is well sealed and airtight to keep it fresh. It will remain fresh for about a month.

To maintain the quality and cleanliness of the water after a few months, chlorine may be required.

It is possible to store water for up to two years if it is not directly from the tap and has been cleaned and filtered at an approved water treatment plant.

Are you preparing your water for storage?

When storing tap water, it is vital to use the proper container for the job. All types of containers, including glass, enameled metal, and fiberglass, are appropriate for the task at hand. You can also use plastic containers if you want, but make sure they’re of food-grade quality before using them. These containers are commonly referred to as “HDPE 2” containers.

Before filling the bottles with water, check to see that they are clean and in proper functioning condition. Keep outdated milk jugs and water bottles out of the recycling bins. The likelihood is that you will not clean them thoroughly enough, and these thin polymers deteriorate quickly, allowing bacteria to enter your drinking water supply. After you’ve finished preparing your containers, you’ll need to start thinking about your water.

Tap water is typically considered to be safe and does not necessitate any additional treatment. Using a water filter before filling your bottles is recommended if your water needs to be filtered or if you prefer it that way. Tap water should have at least 2 to 4 parts per million (ppm) of chlorine to effectively eliminate bacteria. If your water supply does not contain chlorine, you will have to add it yourself (most do).

What is the most efficient method of storing filtered water?

Your water bottles will need to be stored in a secure location once they’ve been filled with water. Refrigerating water is permitted, and it will give cold water as and when required. Refrigeration also helps to inhibit bacterial growth in water by keeping it cool. However, refrigeration isn’t necessarily necessary in this case.

You can store your water in any cool, dark spot that you like. Basements, garages, crawl spaces, and cellars can all benefit from sturdy shelving for storing water and other liquids. If you’re storing a large amount of water in case your water supply goes out, make careful to store it in several different areas to avoid contamination. If something happens to spoil or pollute some of the water you’ve stored, you’ll be prepared with a backup plan.

What is the shelf life of stored water?

While properly managed water should never expire, even filtered water can develop a disagreeable taste after being exposed to the elements for an extended amount of time. It is recommended that you update your emergency water supply every six months, according to the website. When replenishing your water supply, keep in mind that you’ll need at least 1 gallon of water per person every day for the first several days.

For everyday usage, you’ll want to change the water in your refrigerator more frequently to keep its taste fresh. In this circumstance, you should replace any residual water once a month. Water can also be frozen, which prevents impurities such as plastic from escaping into the water.

You should use preserved water within two to three days of opening it if you have it in a container that has been sitting for a while. It will last a little longer in the refrigerator, with a shelf life of three to five days. After that, the water will be safe to drink, albeit it may not taste quite as good as it did before.

What Should You Do If You’re Not Sure to use the stored water?

When water is stored, it should not be consumed if the water appears hazy or has particles floating in it. Apart from that, it’s best not to swim in water that has been exposed to the sun and has begun to generate algae.

The water should be rejected even though it looks to be in excellent condition. If the water smells weird, it should be discarded. You can try a small sample if you’re still not convinced. If you have any questions, it is best to discard the water rather than drink it. When water is scarce and it would be foolish to refuse it, boil or filter doubtful water before drinking it to avoid contamination.
