How to store bottled water for long term?

Storing bottled water for the long term is crucial for emergency preparedness and ensuring a safe water supply. Proper storage methods prevent contamination, degradation of the plastic, and maintain water quality for extended periods.

How to Store Bottled Water for Long-Term Use: A Comprehensive Guide

Ensuring you have a reliable supply of safe drinking water is a cornerstone of any good emergency preparedness plan. Storing bottled water for the long term might seem straightforward, but a few key practices can make a significant difference in its safety and usability down the line. This guide will walk you through the best methods to store bottled water, ensuring it remains potable for years to come.

Why Proper Long-Term Bottled Water Storage Matters

The primary goal of long-term water storage is to preserve water quality and prevent contamination. Bottled water, especially when purchased in bulk for emergencies, needs to be stored correctly to avoid issues like plastic leaching, microbial growth, or degradation from environmental factors. Storing water correctly means you can rely on it when you need it most, such as during a natural disaster or a municipal water supply interruption.

Choosing the Right Bottled Water for Storage

Not all bottled water is created equal when it comes to long-term storage. Opt for water that is sealed and has a long expiration date.

Source: Spring water or purified water (like distilled or reverse osmosis) are excellent choices. Avoid mineral waters with added electrolytes or flavors, as these can degrade over time.
Packaging: Look for bottles made from food-grade PET (polyethylene terephthalate) plastic. These are generally safe for long-term storage. Avoid bottles that appear damaged, dented, or have compromised seals.

Ideal Storage Conditions for Bottled Water

The environment where you store your bottled water plays a critical role in its longevity. The key is to create a stable, protected setting.

Temperature Control: The Biggest Factor

Extreme temperatures can degrade the plastic bottles and potentially affect the water inside.

Cool and Consistent: The ideal storage temperature is between 50°F and 70°F (10°C and 21°C).
Avoid Fluctuations: Large temperature swings can cause condensation inside the storage area, promoting mold growth on the bottles. This can also stress the plastic over time.
Never Freeze: Freezing water can cause the plastic bottles to crack or burst, rendering the water unusable and creating a mess.

Light Protection: Keep it in the Dark

Direct sunlight is a major enemy of stored bottled water. UV rays can degrade the plastic, potentially leaching chemicals into the water and affecting its taste.

Dark Locations: Store your water in a dark closet, basement, or a dedicated storage bin.
Opaque Containers: If storing in a slightly less dark area, consider placing the bottles inside opaque plastic bins or cardboard boxes.

Location, Location, Location: Where to Store Your Water

Choosing the right spot is paramount. Think about accessibility and protection from hazards.

Away from Chemicals: Never store bottled water near cleaning supplies, pesticides, gasoline, or other chemicals. Plastic is porous, and fumes can seep into the water.
Stable Surfaces: Ensure bottles are stored on a stable, level surface to prevent them from tipping over.
Elevated Storage: In areas prone to flooding, store water on higher shelves or elevated platforms.

How to Organize and Rotate Your Stored Water

Effective organization ensures you use older water first and always have fresh supplies.

First-In, First-Out (FIFO) Method

This is a simple yet highly effective strategy.

Label Clearly: Date your water bottles when you purchase them.
Store New Behind Old: When you buy new water, place it behind your existing stock.
Use Oldest First: When you need water, grab from the front of your stored supply.

Rotation Schedule

Most commercially bottled water has a shelf life of about one to two years. While the water itself may remain safe to drink for much longer, the plastic bottle can degrade.

Replace Annually: A good practice is to replace your stored water supply at least once a year.
Check Seals: Before storing, always check that the bottle’s seal is intact.

Storing Water in Different Containers

While pre-bottled water is convenient, you might consider storing larger quantities.

Large Water Barrels and Tanks

For significant water storage, consider food-grade plastic barrels or tanks.

Material: Ensure they are made from BPA-free, food-grade plastic.
Cleaning: Thoroughly clean and sanitize barrels before filling.
Water Treatment: You may need to add a water preserver or use a water purification tablet designed for long-term storage.

Using Your Own Containers

If you fill your own containers, such as reusable water bottles or jugs, follow these guidelines:

Cleanliness is Key: Wash and sanitize containers thoroughly.
Use Treated Water: Fill with filtered or purified tap water.
Add Preservatives: Consider using a water preserver solution or a purification tablet.

How Long Can You Really Store Bottled Water?

Commercially bottled water typically has a recommended "best by" date, usually around two years. However, the water itself can remain safe to drink for much longer if stored properly. The primary concern is the degradation of the plastic bottle over time, especially when exposed to heat or light.
