How to Survive When You Have No Water Source

Survive When You Have No Water Source

Water is one of the three critical elements necessary for survival.

When attempting to survive in the wilderness, there are three things that any human being needs (listed in order from least to most critical): shelter, food, and water. You can survive without shelter for varying amounts of time, depending on the climate and weather patterns; you can survive without shelter and food for up to three weeks; but how long can you survive without water?

A meager four days at the most.

The tips and tricks in this guide will give you a few pieces of advice that can help you turn these four days into a greater amount of time while waiting to be rescued.

Dehydration Is Torture

Imagine having a mouth full of sand as your eyes begin to blur and no matter what you do, you just can’t cool your body off. These are a few of the symptoms of severe dehydration. This situation can feel like torture, like you’re trapped inside of your own body with no possible escape.

Creating Your Own Water Supply

Unfortunately, when you’re in a survival situation, many of the already-limited options that you’ll have will likely be incredibly difficult or even disgusting.

The Rock, Tarp, and Urine Technique

Also known as a solar still, this technique involves using urine to create drinkable water. Before you start to gag, however, know that you won’t be drinking the urine itself. Simply dig a hole and set a cup in the center. Next, place the plastic tarp over the hole and firmly secure it to the sides of ground surrounding the hole so that it doesn’t fall in.

The last step is to place the small rock at the center of the tarp so that it sags down just over the cup. This will cause the water, when it evaporates from the urine, to “filter” by condensating on the tarp, sliding down to where the rock is, and dripping into the cup. This method also works with salt water, but that is not always available.

Follow Animals

If there are any kind of animals, particularly larger animals such as deer or bears, stealthily track them. Larger animals require larger amounts of water, a requirement that they normally cannot satisfy simply by eating. Instead, they typically know where you can find a reliable water source. Following them will enable you to find that water source.

If, however, there are no large animals and there are only small animals, such as squirrels and birds, then that means that their might only be fruits, nuts, and perhaps vegetables but not much fresh water. If that’s the case, eat as many fruits and vegetables as you can in order to consume their internal water reservoirs.


While drinking the condensate from your own urine and tracking potentially life-threatening animals might not seem like the best use of your time, it can prove critical to your survival. Without a reliable source of water or other form of hydration, you will not survive.
