Water Treatment & Containment

You need to provide 1 gallon of water (3.7 liters) per person per day for you and each of your family members if you don't have access to clean water or a faucet.

Think about that for a minute. That's a lot of water. 

A half gallon (2 liters) is what you need for drinking each day - in warm weather or during periods of high stress or activity that amount could double.

What's left is for hygiene, which is critical for maintaining health and comfort. Don't skimp! You will need to wash your hands frequently especially if suddenly exposed to large groups of people in over-crowded situations.

A gallon of water weighs 8.3 pounds. A 3-day supply will weigh 25 pounds. That's probably already the total weight of your Bug But Bag! So carrying a 3 day supply may just not be possible.

Especially true if you are bugging-out on foot. If you have use of a vehicle then you have more options: water bottles, 5-gallon buckets, etc.

So understanding proper water treatment for drinking is super important for prepping!

Understanding the Risks

So you need to find water - can you just mosey up to the nearest pond or lake or pool and start drinking? As delicious as that sounds, no, you can't, not unless you like to get sick.

There are all manner of things you need to be careful of when going for unknown water: bacteria, viruses, and chemicals. We have an article about that here which is required reading and the US CDC page here gives you more info.

It's easy to become a little crazy about the whole thing, but the bottom line is you should have a way to purify enough water to get you through a week or more.

The good news is you have several different options. Having more than one option is a very good thing...so keep that in mind while reading the list below.

Bacteria, Viruses, & Chemicals

Water can be treated at home should the need arise by using bleach, iodine, boiling, or swimming pool shock. The US Center for Disease Control has an excellent page about home treatment. Go ahead and look at that page now, and share it with as many people as you can. It's incredibly important information.

The only way to be completely sure your water is safe from bacteria and viruses is to boil it. Once the water has reached boiling temperature you have raised it enough to destroy them. However, this may not protect you from potential chemical contamination.

Portable Water Filters

For weekend road-trips we bring our own water along and we use stainless steel Fusti 5 liter (3.9 gal) containers with spigots. These come in all sizes and are really useful.

Go Berkey Kit plus Sport Bottle plus accessories

Go Berkey Kit plus Sport Bottle

Typical Price: $187

Go Berkey Kits can take raw-untreated water from almost any source and purify it, removing bacteria, viruses, and chemicals. It uses a ceramic element in a gravity fed system to do the trick in the GO, or you can use suction with the smaller filter in the SPORT (or get the Sport by itself).

The only downside to the GO is it's size, it isn't really packable. It takes about 45 minutes to purify a gallon.

See our article about Berkey filters, and we we think they rule!


Sawyer Mini Water Filtration System

Sawyer Mini Water Filtration System

Typical Price: $16

This system is top-notch. Only weighs 2 oz! Filters up to 10,000 gallons (the secret is it's back washing system) with a 0.1 micron filter. That covers you for bacteria and viruses.

Portable Aqua Water Purification Tablets

Portable Aqua Water Purification Tablets

Typical Price: $7

If boiling is not possible, treat water with chemicals. Try to filter sediment by using a coffee filter, t-shirt, or whatever you can to make it as clear as possible. Each Potable Aqua tablet contains 20 mg of Tetraglycine Hydroperiodide, which liberates 8 mg of titratable iodine when used. In 30 minutes the iodine will make the water safe to drink.


Water Containers

You have a million options when it comes to carrying water, but once you really consider some of the conditions you may face in a bug out situation, your options shrink pretty fast.

Remember, you need to be able to boil your water to truly ensure it is bacteria and virus free (if possible.)

Therefore we feel you must have at least one stainless steel container 32oz or larger. (Keep in mind that this would mean boiling water 4 times a day to meet your 1 gallon drinking needs.) Don't go too much larger though as weight could be an issue.
