Put your safety first


Avoid electric shock by wearing rubber boots when standing in water.


Shut off the power to the flooded area at the breaker box, and keep extension cords out of the water.


If you suspect sewage contamination, contact your environmental health officer or community health representative.

4 steps to safe and timely flood cleanup:

Step 1: Prepare

  • Open windows and doors to circulate fresh air
  • Assemble equipment, renting rent bigger items such as shop vacuums and pumps if necessary

Step 2: Remove water, mud and debris

  • Remove water with pumps or pails, then with a wet/dry shop vacuum
  • Clean walls and furnishings with unscented soap and water, then dry them with a wet/dry shop vacuum
  • Clean and dry all floors as quickly as possible

Step 3: Dispose of items that do not dry quickly
