Collecting Water For Storage

Before diving into the specifics of water purification and storage, let’s explore different methods of collecting water for long-term storage. While tap water is readily available for most of us, relying solely on it during emergencies might not be sufficient. Consider these alternative sources.

Rain Barrels

Rain barrels are a cost-effective and eco-friendly way to collect rainwater for storage. Simply place a barrel under your roof’s downspout, and it will capture rainwater during showers. Be sure to install a screen or mesh to filter out debris and contaminants. This collected rainwater can be used for various purposes, including drinking and cooking, after proper purification.

Freshwater Lakes or Streams

If you live near freshwater sources like lakes or streams, you have a readily available supply of water. However, collecting water from natural sources requires proper filtration and purification to ensure its safety for consumption. Invest in a portable water filtration system or purification tablets for this purpose.

How Much Water Do You Need to Store for Emergencies?

Determining the quantity of water you should store for emergencies depends on several factors:

Family Size: Consider the number of people in your household.
Climate: Hotter climates require more water for hydration.
Duration of Emergency: Prepare for a minimum of three days, but ideally for at least two weeks.
Special Needs: Infants, elderly individuals, and those with medical conditions may require additional water.

A general rule of thumb for your emergency stockpile checklist is to store at least one gallon of water per person per day. For a family of four, this means storing 12 gallons for a three-day supply. Don’t forget to account for pets as well!

Materials Needed for Water Purification and Storage

To ensure your stored water remains safe and potable, you’ll need some essential materials:

Containers: Food-grade plastic containers or glass bottles are suitable for long-term storage.
Water Filters: Invest in high-quality water filters capable of removing bacteria, viruses, and contaminants.
Purification Tablets: Chlorine dioxide or iodine tablets are effective water purification products.
Bleach: Unscented liquid bleach with no additives can be used for water disinfection.
Funnel and Siphon: These tools help in transferring water to storage containers.

How Do You Purify Water for Long-Term Storage?

You should always purify water before storing it to prevent bacteria and microorganisms from growing and multiplying as the water sits. Learning to perform proper water purification is a critical basic survival skill that can help you keep your stored water safe for extended periods.

Here are three effective methods for water purification.

The Boiling Method

Boiling water is one of the most straightforward and effective methods to kill harmful microorganisms. Simply bring water to a rolling boil for one minute (or three minutes at higher altitudes) and let it cool before transferring it to clean, sanitized containers. Boiling is particularly useful if you’re unsure about the quality of your water source.

The Liquid Bleach Method

Liquid bleach can be used to disinfect water, making it safe to store for an extended period. Use only unscented bleach with no additives. Add 1/8 teaspoon (or 8 drops) of bleach per gallon of water, stir well, and let it sit for 30 minutes before sealing in containers.

The Iodine Tablet Method

Iodine tablets are a convenient way to purify water for storage. Follow the manufacturer’s instructions for the appropriate dosage and contact time. Generally, one tablet is sufficient for one quart of water. After the prescribed time, your water will be safe to consume or store.

What Containers Should You Store Water In?

Selecting the right containers for water storage is crucial to prevent contamination and ensure the longevity of your stored water. Consider the following guidelines:

Food-Grade Plastic Containers: Choose containers made of BPA-free plastic designed for storing food or water. These are typically available in various sizes and are stackable for efficient storage.
Glass Bottles: Glass bottles are a durable and non-permeable option for long-term water storage. Ensure they have airtight seals to prevent leakage and contamination.
Metal Containers: Stainless steel or aluminum containers can also be used, but make sure they are lined with a food-grade coating to prevent corrosion and flavor transfer.
Avoid Containers That Have Held Non-Food Substances: Containers that previously stored chemicals or non-food items may leach harmful substances into your water.
Regular Inspection and Rotation: Regardless of the container type you choose, regularly inspect and rotate your water supply to maintain its freshness and quality.

How Long Can You Store Water?

Water can be stored for an extended period, provided it is properly purified and stored in suitable containers. Here are some general guidelines:

Tap Water: If stored in a clean, sealed container in a cool, dark place, tap water can last for six months to one year. However, it’s recommended to rotate it regularly.
Commercially Bottled Water: Sealed commercial bottled water typically has a shelf life of two years or more. Again, store it in a cool, dark place and check the expiration date.
Purified Water: Water that has been properly purified and stored can last indefinitely if kept in the right conditions. Check the container’s integrity and cleanliness periodically.

Other Water Storage Tips

To ensure the safety and reliability of your long-term water storage, keep the following tips in mind:

Label and Date Containers: Clearly label each container with the date it was filled and the purification method used. This helps you keep track of rotation.
Store in a Cool, Dark Place: Keep your water supply away from direct sunlight and temperature extremes to prevent the growth of algae and bacteria.
Use Preservatives: If you’re concerned about microbial growth, consider adding water preservatives, which can extend the shelf life of your stored water.
Regularly Rotate Your Supply: Even though properly stored water can last a long time, it’s best to rotate it every six months to ensure freshness.
Have a Water Purification Plan: In case your stored water is depleted or compromised during an emergency, have a backup plan for purifying available water sources.
