Water for Survival. What You Need To Know

  1. 1. After 3 days with no water, we die. What You Need To Know; How To Get It. THE GREEN BERET PREPARATION AND SURVIVAL GUIDE
  2. 2. Water Over 3/4ers of our body is composed of fluid. Just passively existing, we lose almost a half gallon per day. That goes up drastically if we are active. Thus we need at least one gallon of water per day.
  3. 3. Water The quickest and most effective emergency preparation we can do is stock water. Stock a minimum of one case of 500ml bottles per person (three days worth). I recommended it be 2 cases per person. Just grab it the next time you’re in the store. Do it now!
  4. 4. Water
  5. 5. You must have a way of quickly filtering water for your family. There are numerous ones available. Here is one I purchased. There is also a slightly more expensive system that doesn’t require pumping and works via gravity. Either one can be a lifesaver for your family after a disaster. Water
  6. 6. Water A 5% drop in body fluid will cause a 25% drop in energy level. A 15% drop will cause death. It is estimated that 80% of people are chronically dehydrated.
  7. 7. Water Also, dark or smelly urine usually indicates you are dehydrated.
  8. 8. Water Assume all water in nature to be contaminated. During catastrophes, your regular water sources are often contaminated. How safe is your everyday drinking water?
  9. 9. Water In an emergency, we have water in our house that we don’t readily think of: The water heater. The water pipes. The toilet tank (not the bowl).
  10. 10. 4 full 500ml water bottles. This is your immediate emergency supply if you have no time to fill up your . . . Containers. Either a built in water supply such as a Camelbak or pockets/clips for water carriers. Most packs have external loops on which you can secure canteens and water carriers. Your first priority is to fill up this container with potable water or fill from your household water stash if bugging out. The four water bottles are to sustain you to get to that point. They also then become extra water containers. WATER-Grab-n-Go Bag
  11. 11. A built in Camelback can be useful. Canteens. I have a military issue 2 quart on the outside of my bag. Click on image for it. Water bottles. Remember, water freezes if carried externally . Water Carrier
  12. 12. Assume all water you find is not fit to drink unless purified. Giardia is very common, even in remote locales. If you don’t have the pump or gravity filter, I recommend the following for your grab-n-go bag, car, work, school: Lifestraw. Purifying tablets. Click on images. Water
  13. 13. In an emergency you can purify water by disinfecting it.
  14. 14. Water in Nature Purify all water you aren’t certain is pure. Collected rainwater is usually safe. Eating snow or ice without melting first will reduce your core temperature and lead to dehydration. If you have to melt either to get drinkable water, use ice rather than snow, if possible, as it takes less energy.
  15. 15. No matter what you’ve read (unless you’re a vampire):
  16. 16. SoDis Water Disinfection Solar Water Disinfection: Find a clean, clear plastic bottle no more than three liters (1 liter is slightly more than one quart). It needs to be a PET bottle. You can tell by looking on the bottom. Most will say if they are PET or PETE. Otherwise it will have a number. You want a #1. The narrower the bottle, the better for solar penetration.
  17. 17. SoDis Water Disinfection Fill it three quarters full with clear water, or water you have filtered through sand or whatever you have available. Shake the bottle in order to get as much oxygen as possible into the water. Fill the rest of the bottle and replace the lid. Place the bottle in direct sunlight for six to eight hours. You can increase the efficiency by placing the bottle on a reflective surface such as metal or aluminum foil. If you have to move, hang the bottle on the outside of your pack.
  18. 18. SoDis Disinfection How SoDis works? The sunlight treats the water through three ways, all involve radiation. UVA reacts with the oxygen dissolved in the water to produce a highly reactive form with free radicals and hydrogen peroxide, which kills microorganisms. UVA interferes with the reproductive cycle of bacteria by crippling their DNA. The sunlight heats the water and once it gets it above 122 degrees, the disinfection works three times faster.
  19. 19. Water Rules of thumb in nature in extreme emergencies: Running water is better than still water. Water coming out of a spring is better than running water. Clear water is better than cloudy or discolored water. Avoid water with algae. Avoid swamp or marshland water.
  20. 20. Water Scavenging In essence, a sealed water bottle has no expiration. Where can you find them? Also, consider houses with high end filtering systems— get the filters, connect, let gravity push water through them.
