Pollution Prevention Tips for Homeowners Preparing to Evacuate from Flood

Flood Preparation and Pollution Prevention

Flooding conditions often require extended absences from homes and businesses. Planning ahead can help protect the environment and make cleanup easier when you return. Consider the following pollution prevention and safety measures:

Household Chemicals

Check basements, sheds, garages, and other flood-prone areas for items such as paint, gasoline, pesticides, and other household chemicals.

  • Move hazardous materials to a safe, dry location.
  • Properly dispose of unwanted chemicals.
  • Take materials to a household hazardous waste collection site if available.
  • Secure outdoor items such as propane tanks to prevent them from being washed away.

Learn more about propane safety from the University of Nebraska–Lincoln Extension flood resources .

Septic Systems

Septic systems may not function properly when flooded or when surrounding soil is saturated.

Review guidance on managing septic systems before, during, and after flooding at: Managing a Septic System Before, During and After a Flood .

Refrigerator and Freezer Safety

Food left in refrigerators or freezers without electricity can spoil and create health hazards.

  • Remove perishable food if you expect extended power loss.
  • Dispose of spoiled food safely during cleanup.

For guidance, see: Food safety before and after floods (UNL Extension) .

Equipment and Vehicles

Move vehicles, lawn equipment, and machinery out of flood-prone areas. This helps prevent:

  • Damage to electrical systems and interiors
  • Leaks of gasoline, oil, or antifreeze

Evacuation Planning

Flooding conditions can change quickly. Be prepared to follow instructions from local, state, or federal officials.

  • Develop an evacuation plan in advance
  • Be ready to leave immediately if directed
  • Review safety guidance from the American Red Cross
