How to Store Water for Emergencies

Shares

Welcome to Water Wednesdays, our series on everything you need to know about conserving water, arguably our most precious resource. Catch up with parts one and two.

As we examine the many water crises that have come and gone, one important characteristic has quickly become apparent: storing water for emergency use is vital.

Between hurricanes and flooding that contaminate water supplies to earthquakes that disrupt supply lines, there are a variety of causes that can force you to lose access to your normal water supply. This is why it’s so important to keep some water stored and ready for any emergency that may come.

How to Store Water for Emergencies

It’s recommended that when possible, you store commercially bottled water for emergencies. This water has a long shelf life and all you really need to do is keep it stored in a cool, dark place. The downside to commercially stored water is that it’s generally only available in small quantities and in containers that aren’t the most durable.

While storing some commercially bottled water is a great idea, enhance your water storage with a few larger storage containers. There are several attributes to consider when selecting long-term water storage. The containers should be opaque, not clear, and should seal tightly. These attributes will help your water containers stay free of bacteria.

These containers should also be made of food-grade plastics. While we generally try to avoid too much plastic in our lives, in this case, plastic is one of the best options out there. There are other containers like glass and stainless steel, but ultimately plastic wins out when you compare the pros and cons.

When you purchase empty containers intended for water storage, clean them with dish soap and then sanitize them with a teaspoon of non-scented liquid chlorine bleach with a quart of water. Once they’ve been cleaned and sanitized, fill them up. You’ll want to replace this water every six months.

How Much Water Should I Store?

Most experts agree that you should have a gallon per person per day. Half of that water is intended for drinking, while the other half is for sanitation and hygiene. It’s also recommended that you have at least 14 days’ worth of water. So if you have three people in your home, that’s 42 gallons.

Water Storage Containers

If you currently have no water storage, you may be tempted to simply buy a couple of cases of water bottles and call it good. While this is certainly better than nothing, there are far better options out there.

For portable water containers, look for ones in the 3- to 7-gallon range. When full, these are still portable by the average person. Any larger than that and it starts to get substantially more difficult to carry them. A popular option is the water brick, which holds 3.5 gallons. What is particularly convenient about these is they stack really well, making storage much easier. However, water can be difficult to get out. While they do have an optional spigot you can buy, due to the container’s square shape, it’s difficult to get all the water out, and inevitably you’ll be forced to tip it over to get the last third of the water out.

A great option for portable water storage is the 7-gallon container made by Reliance. These containers have been around for many years and have proven themselves to be reliable. They can be quite heavy, weighing nearly 60 pounds when full, but they are still rather portable and it’s fairly easy to throw a couple in the car if necessary. When tipped on their side with an attachable spigot, they’re easy to drain.

If you’d like to store a larger amount of water, 55-gallon drums are a fantastic option. There are a number of manufacturers that make these food-grade plastic barrels; Auguson Farms is one particularly popular brand. With 55-gallon drums, it’s important to also purchase a pump to get the water out of the barrel for use. Get a water preserver for treating it before drinking.

What Not to Do

The biggest mistake people make with water storage is not changing it out on a regular basis. While water can remain drinkable for a long, long time, it should not be left stagnant in a container for years. This is especially true of containers you fill. Commercially filled containers generally have a much longer shelf life.

Another common mistake is to not have a way to purify the water or get it out of the containers. Having a 55-gallon drum of water is great, but with no pump to get that water out, you’re going to have a huge challenge on your hands. When you do decide what kind of container to store water in, make sure you find an appropriate way to get it out. Also know how to use bleach or other water-purifying tablets when it comes time to actually use that water in an emergency.
