Finding drinking water in the wilderness can be a difficult and daunting process, but it is possible, even in the desert. From best to worst case scenario, there are several tips to help people outdoors with the most important aspect of wilderness survival-staying hydrated.

The best case scenario is for the person to carry a filtration system, which can be found at countless outdoor supply stores and websites at reasonable prices. A decent filtration system will allow the safe use of water from nearly any abundant source-rivers, streams, lakes, and even mud puddles. Water is very heavy, so hikers on a trail for any distance have learned to find the water sources along the trail before they begin the hike, carrying only as much clean water as they need before the next refill site is found.

It is a very good idea to carry one full extra liter bottle of water per person (I usually re-use a soda bottle), just in case the next water supply is dry; this base amount can be varied depending on distances, terrain and temperature. This emergency supply is just as important as finding out as accurately as possible the number and location of each water source (as well as the seasons it will most likely have water).

Should complications arise such as a dry source or a lost/broken filter, there are ways to find drinking water in a pinch. If a person knows their body, they can estimate whether they can make it to the next source; however, even if they believe they can do so, they should spend the time during the hike forming contingency plans in case they do not make it or find another dry source.

If there is vegetation in the area, a thirsty hiker can take advantage of that by using a plastic bag. By placing green vegetation into the bag and sealing or tying it closed, then placing the bag into the sun, the vegetation is heated up and dried out while the plastic catches the water vapor. This method will not capture much water, but any clean water is better than none.

Another similar method for obtaining clean water is the solar still. It requires a larger piece of plastic such as a garbage bag as well as a container for water collection. The first step is to dig a hole covering about one half the area size of the plastic sheet. If green vegetation is available, line the bottom and sides of the hole with it. Also, use any other form of moisture including stagnant water, rainwater, or even urine to moisten the ground in the hole.

After lining the pit, place your collection container
