Water for Living and Survival. What You Need To Know

  1. 1. After 3 days with no water, we die. What We Need To Know about water for Preparation and Survival
  2. 2. 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 one gallon of water per day at a minimum.
  3. 3. 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.
  4. 4. Assume all water in nature to be contaminated. Giardia is no fun. During catastrophes, your regular water sources are often contaminated. How safe is your everyday drinking water?
  5. 5. I highly recommend no matter where you live, have at least a basic under sink filter on one tap, from which you draw all the water you are going to drink.
  6. 6. 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 at least 2 cases per person. Just grab it the next time you’re in the store. Do it now!
  7. 7. 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).
  8. 8. 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 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
  9. 9. A built in Camelback can be useful. Canteens. I have a military issue 2 quart in my bag. Click on image for it. Water bottles. Remember, water freezes if carried externally . Water Carrier
  10. 10. On my Jeep I carry a 15 liter plastic container inside. I use that for camping. On top, I carry a 2 gallon rotopax container. I also have several water filters (covered watered). Water Carrier
  11. 11. Compressible water containers. For after establishing base camp Purification. Lifestraw or equivalent and two bottles purification tablets. Click on images below for links. Water
  12. 12. You must have a way of quickly filtering water for your family. Assume all water you find in nature is contaminated. Besides the life straw and pills, there are ones that produce more volume. 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.
  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 if the surface it comes off of isn’t contaminated. 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 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. Dark and/or smelly urine usually indicates dehydration.
  18. 18. SoDis Disinfection How SoDis works? The sunlight treats the water through three ways; all involve the sun’s 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 and Plastic While I recommend bottled water for your emergency supply, the reality is that bottled water contains micro plastic particles. The bottles are also bad for the environment. For our drinking water we use metal bottles that we fill from our filtered tap. This gets rid of drinking micro-plastic and is good for the environment. When storing water in plastic, check the type: use PET or PETA#s 1, 2, 4 and 7. Avoid thin plastic such as milk or gallon water jugs. They will eventually leak, especially if not stored in a cool place.
  20. 20. Water First Aid Signs of dehydration are: Dark urine with a very strong odor Low Urine Output Dark, sunken eyes Fatigue Emotional instability Heat Exhaustion and Heat Stroke and Over-Hydration are covered in the book.
  21. 21. SoDis Water Disinfection Fill it three quarters full with clear water, or water you have filtered through sand, cloth 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.
  22. 22. 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.
  23. 23. Water Scavenging In essence, a sealed water bottle has no expiration. Also, consider houses with high end filtering systems— get the filters, connect, let gravity push water through them.
  24. 24. More Free Information I constantly update free, downloadable slideshows like this on my web site for preparation and survival and other topics. www.bobmayer.com/workshops Also, I conduct Area Study workshops for those interested in properly preparing for their specific circumstances.
  25. 25. The guide on the left is the complete preparation and survival guide. The one on the right is a pocket-size manual with just the survival portion. Useful in your Grab- n-Go bag, car and kitchen drawer. SURVIVAL GUIDES
