What are 3 ways to preserve water?

Here are 3 ways to store and preserve water.

  1. Storing water in a water storage tank
  2. Storing water In food-grade containers
  3. Storing purchase bottled water

In the event of a disaster, household water supplies, particularly drinking water, may be impacted, therefore having a supply of stored water is critical. Each person needs at least three liters of drinking water every day. Water is also required for cleaning and cooking.

How to store water in a water storage tank?

Having a backup water storage tank is the easiest way to store water. There are many types and sizes of water tanks available for domestic use. Always make sure that the water tank is easy to clean and is made of food-grade material. 

If you need to store a large amount of water a storage tank is the best option. The disadvantage is that storage tanks are not easily movable and if your tank gets damaged during a disaster, or is out of reach, you will have a hard time using the water.

Change the water in the storage tank at least once every 6 months. 

Here’s an example of an emergency water storage tank that can store up to 275 gallons of water.

Emergency Water Storage Tank (275 gallons)

These 275-gallon emergency water storage tanks are manufactured from approved food-grade polyethylene, allowing you to store pure water without worry of contamination. When the electricity goes off, the tank uses a gravity-fed system, which removes the need for expensive water pumps. There are two spigots on the tank that can be connected to a hose.

Storing water in food-grade containers

When storing drinking water, food-grade water storage containers are preferred since they do not transfer harmful compounds into the water. 

Food-grade storage containers that have been certified by the FDA can be found at many stores. If you’re not sure if a storage container is food-grade, contact the manufacturer.

Food-grade water containers are a great option to store water. They come in many shapes and sizes depending on your need.

Here are some food-grade water storage containers that are great to preserve water for an emergency.

Stackable 5-Gallon Containers

The flat bottom and top of these stackable, space-saving containers allow them to be stacked on top of each other. This design allows you to store enough water in little space. 

The containers include a built-in handle that makes them easy to transport, which is vital if you don’t have a lot of time. These canisters can hold enough water for 40 days.

Carbon Steel Drum, 55 Gallon

The rust-resistant carbon steel drums are durable containers for storing water in the event of an emergency. These containers have a rust-resistant inside coating and rust-proof coating on the exterior. This allows you to use these containers for many years without damage.

How to store-bought bottled water?

You can also purchase pre-bottled water to keep on hand. 

Bottled water is packaged in sterile, tightly sealed plastic containers that keep the product’s quality and freshness. Plastic containers, for bottled water, are slightly porous, allowing ambient air gasses such as vapors from home solvents, chemicals, and petroleum-based fuels to impact the flavor and odor of your water.

Algae or mold can form when bottled water is exposed to direct sunlight or heat sources for long periods. Although it is not a public health hazard, storing water in a cold, out-of-the-way location helps you to keep your water fresh, and clean.

On store-bought water, the best-before date specifies how long the producers can assure the quality. After the best-before date, bottled water may have a different flavor. This is because the bottle because plastic can change the taste of water. This doesn’t mean it’s harmful to consume.

Since store-bought water is always of potable water quality, it is good to always have a few small water bottles in an easily accessible location.

What are the tips for preserving water?

  • Before choosing a method to preserve water, find out how much water you use daily. This depends on the number of people in your household as well as the amount of cleaning and washing you do daily.
  • Keep your water somewhere cool and dark. It’s critical to keep stored water away from heat and light, as they can induce leaks in the containers. 
  • Water should not be stored near flammable liquids such as gasoline, kerosene, or insecticides, as fumes from these compounds may pierce the plastic.
  • Bottled water from a commercial source is the safest and most reliable source of water in an emergency. The bottles of most commercially bottled water will carry an expiration date. Make sure the date is correct.

    They are usually good for up to a year. If you bottle your water from the faucet, replace it every six months.
