Doomsday Survival Guide Part I: Water and Food

There are many things to consider when preparing your doomsday survival guide. The first part of this series will cover emergency water supplies and food for survival. These are the first two concerns that will need to be addressed for apocalypse survival.

Doomsday Survival: Water

Water needs to be a top priority for apocalypse survival. Water lines may be damaged causing contamination, supplies may be limited, contamination may even occur in natural water ways depending on the disaster. A doomsday prepping checklist should have survival water storage at the top.

Each individual will need approximately one gallon of water per day, maybe more if the temperatures are hot. A family of four should have at least 30 gallons of water stockpiled. This will last approximately one week during a disaster. Storing twice this amount is preferable.

During a disaster, emergency water supplies should only be used for eating, drinking and washing hands. Rationing should be implemented from the beginning. If you are bunkered down at home during the doomsday disaster, your urban survival guide may allow you to find additional water from:

  • Hot water heater tank
  • Toilet flush tank (not the bowl)
  • Ice cubes
  • Juice from canned fruits and vegetables
  • Rain collection

This water should be purified to ensure safety. This is done in a number of steps:

  • Filtration – strain water through paper coffee filters, cheesecloth, etc to remove sediment
  • Boiling – boil one to five minutes to kill organisms
  • Chemical Purification – this final step will ensure water is suitable for drinking. Acceptable chemical purifiers include iodine and chlorine.

If your family’s budget allows, you may want to consider purchasing a emergency water filter system for your DIY survival kit. These systems are hand-pumped and can filter out bacteria.


Food for Survival

Your survival food supply should be consumed in this order:

  • Foods from the refrigerator
  • Foods from the freezer
  • Canned foods

Keep a couple of chest coolers with your survival food storage. Thaw items from your freezer in the chest cooler. As these food items thaw, they will keep fresh food cool.

The best survival foods are those that will keep long-term and require little preparation. In addition to storing canned foods items, several companies specialize in survival food supply:


Cooking should be kept simple and outdoors. Do not use your indoor stove as there may be a possibility of ruptured or damaged gas or electrical lines. Use a camp stove or outdoor grill instead.

If water is scarce, avoid using pots and pans. Instead cook canned foods inside their cans. Open the lid and place in a double boiler over your fire. Fresh foods can be cooked in foil. Use plastic and/or paper plates and utensils.

While water should not be wasted on cleaning dishes, you may use leftover hand washing water for utensil and cookware cleanup.

Garbage should be double-bagged and stored away from your survival food storage and sleeping quarters. This will prevent cross-contamination and attracting rodents and insects.
