Health departments and public water safety officials use many safeguards to protect the sanitary quality of your drinking water. However, this protection may break down during emergencies caused by natural disasters. The water supplied to your house may be shut off or become unsafe to use. You and your family may then be on your own to provide a safe and adequate water supply.


A supply of STORED WATER may be your most important survival item. Seven gallons of stored water per person can last two weeks. To keep drinking water safe from contamination, it should be stored in carefully cleaned, noncorrosive, tightly covered containers. Commercially bottled water, stored in packing boxes is an excellent option. Containers of heavy opaque plastic with screw-on caps are best if you choose to bottle your own water. The bottles should be clearly labeled and the water changed every six months. Emergency water can also be obtained from your hot water heater. To draw water from a water heater: (1) turn off the gas/ electric supply, (2) close inlet water valve, (3) open any hot water faucet or disconnect the hot water line at the top of the tank (to let air into the tank), and (4) drain water into a container by opening the faucet at the bottom of the heater. In a disaster, water lines are often cracked or broken and impure substances pollute the water. Immediately after a major disaster, prevent contamination to your home water supply by shutting off the valve that leads to the water main. Don’t take a chance if the water from your tap is cloudy or has an unpleasant smell. Purify before using! How to purify water for drinking: If water is polluted, strain water through paper towels, paper coffee filters, or several layers of clean cloth into a container to remove any sediment or floating matter. Water that is boiled vigorously for five minutes will usually be safe from harmful bacterial contamination (boiling longer is safer, if you have the heat to spare). If boiling is not possible, strain the water as above and treat by adding ordinary liquid chlorine household bleach or Tincture of Iodine. (Do not use granular forms of household bleach, they are poisonous!) Amount of Chlorine Bleach to Add To:

Mix thoroughly and let stand for 30 minutes. A slight chlorine odor should be detected in the water— if not, repeat the dosage and let stand for an additional 15 minutes before using. Purify only enough water at a time to last a maximum of 48 hours. This will minimize chances of recontamination. We hope that your plans for a natural disaster will never be put to the test. But when it comes to survival in emergency situations, there is no such thing as too much preparation. Seven gallons of preparedness now, may mean survival later.
