Emergency Water Supplies

In the aftermath of a disaster, there is a possibility of temporary water supply disruptions or contamination. As water is essential for survival, it becomes crucial to understand the methods of finding and purifying drinking water to ensure its safety. Being equipped with this knowledge empowers you to secure a reliable and potable water source during challenging times.

Store a 3-day supply of water for each family member and assume that at least 2 gallons per person per day should be stored.

Water Sources In the Home

  • Melt ice cubes.
  • Hot water tank: Turn off the power that heats it, and let the tank cool. Then place a container underneath and open the drain valve at the bottom of the tank. Don’t turn the tank on again until water service is restored.
  • Toilet tank: The water in the tank (not the bowl) is safe to drink unless chemical treatments have been added.
  • Water pipes: Release air pressure into the plumbing system by turning on the highest faucet in the house. Then drain the water from the lowest faucet.

Water Sources Outside the Home

Rain water, spring water, and water from streams, rivers, lakes, and coiled garden hoses can be used after it is purified.

Purifying Water

Water can be purified by boiling or using chemicals. Any water that is obtained from sources outside the home or water that does not appear clear should be sterilized. Non-sterilized water may be contaminated.

  • FIRST, strain the water through a cloth or paper filter before beginning the purification process.
  • Boiling water is the most effective method to kill water-borne pathogens.. Bring water to a rolling boil for 10 minutes. Pour the water back and forth from one clean container to another to improve the taste. Adding a pinch of salt or squeeze of citrus can also help.
  • If boiling is not an option, the alternative is to treat the water chemically. Plain household chlorine bleach may be used. Be sure the label states that hypochlorite is the only active ingredient. Bleach containing soap or fragrances is not acceptable.
  • With an eye dropper, add 8 drops of bleach per gallon of water (16 if the water is cloudy), stir and let sit for at least 30 minutes. Afterwards, the water should taste and smell of chlorine. If the taste and smell has not changed at this point, or if the water appears cloudy, add the same amount of bleach as before and let sit for another 30 minutes. If after two doses, the water is still cloudy and/or does not smell and taste like chlorine, then it is not safe to drink.

Water Storage Containers

Store the water in a clean and sanitary glass or plastic container. Plastic containers are good because they are lightweight and unbreakable. Metal containers should be considered as a last resort because they may corrode and give water an unpleasant taste.

Water that local officials report has been contaminated with toxic chemicals or radioactive materials cannot be purified using home decontamination methods.
