Dew Collection for Survival Water
Besides air, water is of primary importance if you hope to stay alive longer than a few days in a survival situation. And if you’re stuck in a place where your source of water becomes polluted and you have no filter available there is still a way to get distilled, potable water — and that is through dew.
Collecting dew is a rather simple process, however there are a few guidelines that need to be followed if you plan on using this method:
Guidelines for Collecting Dew
Do not collect dew in these circumstances:
- On or near poisonous plants
- On plants or objects that are chemically treated or sprayed
- In areas where obvious animal defecation has taken place
- Near roadsides
How to Collect Dew
Dew collection requires only three steps:
Step 1: Find an area with a good amount of dew
The best time to gather dew is in the early morning before the sun has touched your collection area. My favorite areas are fields and untreated lawns. Plants with large leaves like grape or burdock also work fairly well.
Step 2: Wipe up the dew with an absorbent material
The basic way to collect dew is to take an absorbent material such as a cotton t-shirt, lightweight towel, rag, or my favorite: a ShamWow, and wipe it over grass, boulders, or other objects:
This also works for post rain, but there are better ways to collect rain water.
Step 3: Wring out the dew
Next, just wring it out into some container (or your mouth):
Dew Collections Yields and Filtering
You can get quite a lot of dew in a short time. For example, I was able to fill this 16oz glass with dew water in about 3 minutes. That equates to about a gallon of water in a half-hour’s time period! And although it is a bit cloudy, it’s quite potable.
Keep in mind that although dew is really distilled water, if you have a water filter available or at least can boil it, by all means make sure you do it. There is still a chance that you could collect the due from an area where an animal infected with Giardia or another illness has defecated.
