Gather Emergency Supplies

Water Supplies

If a natural or human-caused disaster strikes your community, you might not have access to food, water and electricity for a while. By taking steps now to store emergency food and water supplies, along with a disaster supplies kit, you can reduce the affect of any such disaster on your family.

Detailed information on the steps outlined below can be found in the American Red Cross publication, "Food and Water in an Emergency."

In an emergency, drink at least 2 quarts of water a day, 3 to 4 quarts a day if you are in a hot climate, pregnant, sick, or a child. If supplies run low, don't ration water: Drink the amount you need today and look for more tomorrow. Don't risk dehydration. Emergency assistance should be available within a few days at most.

How and Where to Store Water

Learn where the water intake valve to your home is. If you hear reports of broken water or sewage lines, or if local officials recommend doing so, you would need to shut off water to your house at the incoming water valve to stop contaminated water from entering your home.

Safe Use of Water Containers

  1. Wash containers with dishwashing soap and rinse with water.
  2. Sanitize by swishing a solution of 1 teaspoon of liquid household chlorine bleach to a quart of water on all interior surfaces of the container.
  3. Rinse thoroughly with clean water before use.

Alternate Emergency Water Sources Inside and Outside Your Home

Inside

If a disaster catches you without a stored supply of clean water, you can use the water in—

If your tap water is safe to drink, so is the water in your pipes and hot-water tank, even if the idea seems unappealing. If you don't drink tapwater, the water in your pipes and hot-water tank may still be useful for sanitation.

To use the water in your hot-water tank, be sure the electricity or gas is off, then open the drain at the bottom of the tank. Start the water flowing by turning off the water intake valve at the tank and turning on a hot-water faucet. Refill the tank before turning the gas or electricity back on. If the gas is turned off, only a professional can turn it back on.

To use the water in your pipes, identify and turn on the highest faucet in your home to let air into the plumbing. You then can get water from the lowest faucet.

Outside

If you need to find water outside your home, try

Take steps to make water from any of these sources safer before drinking it. You should not drink flood water. Avoid water with floating material, an odor, or dark color. Use saltwater only if you distill it first.

Ways to Make Outdoor Water Safer

Note: These instructions are not for treating water to be stored, only for emergencies when no other water is available.

Untreated water can make you very sick. Besides having a bad odor and taste, it can contain toxic chemicals, heavy metals and germs that cause such diseases as dysentery, typhoid and hepatitis. Before drinking outdoor water, using it in food preparation or for hygiene, make it safer to use by

None of these methods is perfect. The best solution is to use all of them. Boiling and chlorination will kill most microbes but will not remove other contaminants, such as heavy metals, salts and most other chemicals. Distillation will kill or remove most of any remaining contaminates.
