Finding Other Water Sources in an Emergency

Other sources of clean and safe water can be found inside and outside the home.

DO NOT DRINK water that has an unusual odor or color, or that you suspect might be contaminated with fuel or toxic chemicals. This water cannot be made safe, so you must find a different source of water for your needs.

The following are possible sources of water:

Inside the Home
  • Water from your home’s water heater tank (part of your drinking water system, not your home heating system)
  • Melted ice cubes made with water that was not contaminated
  • Water from your home’s toilet tank (not from the bowl), if it is clear and has not been chemically treated with toilet cleaners such as those that change the color of the water
  • Liquid from canned fruit and vegetables
  • Water from swimming pools and spas can be used for personal hygiene, cleaning, and related uses, but not for drinking.

Listen to reports from local officials for advice on water precautions in your home. It may be necessary to shut off the main water valve to your home to prevent contaminants from entering your piping system.

Outside the Home

Flood waters can contaminate well water and rivers, streams, and lakes with livestock waste, human sewage, chemicals, and other contaminants which can lead to illness when used for drinking, bathing, and other hygiene activities.

Water from sources outside the home must be treated as described in Make Water Safe, because it could be contaminated with livestock waste or human sewage. If you suspect or know the water is contaminated with toxic chemicals or fuels, it cannot be made safe and you should not drink or bathe in this water.

Possible sources of water that could be made safe by treatment include:

  • Rainwater
  • Streams, rivers, and other moving bodies of water
  • Ponds and lakes
  • Natural springs

Note: DO NOT USE water that has been contaminated by fuel or toxic chemicals.
