Finding Water

There's water everywhere, even in the desert. But, collecting that water for use can be a challenge. Here's some hints on finding or making a water supply for some wilderness settings.

Conserve What You Have

First of all, conserve what water you have by following these tips to survive:

Make sure you are looking for water well before you need it. Look for it continuously. When you find and prepare water, use your stomache as a container too. If you have water, fill your canteen and drink as much as you can for the time ahead when it is scarce.

Gather Dew

Depending on the location, you can collect a pint, quart, or gallon of water this way. Its an easy way to get clean, fresh water. Be careful of what types of vegetation you wipe so that you don't also collect harmful oils.


Solar Still

Find a low, damp spot in direct sunlight - a dry creek bed or southern base of a hill. Dig a hole about 4 feet across and 3 feet deep. Dig a smaller hole in the center of the bottom and place a cup in the small hole. Pack earth around it to hold it in place and prevent tipping. Cover the hole with a 6 foot by 6 foot piece of clear plastic sheet. Cover the edges of the plastic with sand or dirt to hold it in place and stop moisture from escaping. Place a stone in the center of the plastic sheet. Adjust the edges of the plastic so the rock sinks down directly over the cup and about 2 or 3 inches above it.
Now, wait. And wait. And wait.
The sun will heat the soil in the hole releasing trapped moisture. The moisture will condense on the plastic sheet, dribble to the center, and fall into the cup. Lift an edge and retrieve the cup when it has water. There should be some water after an hour or two and it will be safe to drink.
You can improve this still by placing a 6 foot plastic tube into the cup and have it run up and out of the hole. Then, you can just suck from the straw instead of disassembling the still to get to the water.
Solar stills can extract moisture from even desert soil. If the soil is very dry, you can fill the bottom of the still with grasses so their moisture evaporates and condenses.

Gather Rain

Rainwater collected directly from the sky could be drunk.
After a rainfall, you could lay out your sheet under bushes or trees and shake the water off of them.



When its cold, you don't feel like you need to drink much. But, that is a serious mistake in winter. The air in winter is usually drier than summer and your body continues to expel water vapor with every breath and every exertion. You also need water to generate heat in your body.
Winter has special challenges for collecting safe water. Water filters will most likely break if used in freezing weather. Either the filters will freeze closed and allow no water to pass or the water expanding to ice will break the filter, making it worthless. So, you will need to purify by boiling or chemical treatment. Since I have to heat ice to water anyway, I prefer to just keep going and boil it.

Here are some things to keep in mind for your winter water supply:
