  1. Sort your belongings. This is the painful part. The sewer backup would have made contact with the things you have in there, damaging some. What you should do is sort them according to those you can clean and disinfect on one side, and those you will have to dispose. Toys, books, cosmetics, etc. will have to go regardless of the extent of contact. Canned products, furniture, clothing, etc. can still be cleaned. Put them in bags and take them out of the area. You need to clear the basement as much as possible. You need to expose as much surface as you can for thorough and deep cleaning.


  1. Scrub and clean the area. There will likely be sludge on the floor and walls after removing the water. Clean it off by spraying water on the areas and remove the dirty water. Sweep debris and other solid dirt with a broom and remove those too. Now fill two buckets. Fill one with a disinfectant solution such as this Diversey according to its label. It is multipurpose and will kill 99.99 percent of bacteria and also eliminates odors. The other bucket should be filled with clean water. Wash the walls with rags and the floors with a scrubbing brush using the disinfectant solution. Once done, rinse the walls with the clean water. You can do another round by with the disinfectant solution for peace of mind. We suggest that you start with the area farthest from the door and work towards it.


  1. Ventilate the area. After you have removed the water from disinfecting the floors and walls, open the windows. This will allow the area to dry up and air out. You can put on a fan or a dehumidifier to make the process more effective.

Certainly, don’t make body contact as well. Get a hot shower washing your body with an antibacterial soap. Use a nailbrush to scrub your fingers and toes making sure they’re clean.


  1. Contact the utility companies again. This time you want to ask them to come inspect your appliances and connections to make sure it is safe to restore supply.
