Discard any items contaminated by sewage if they cannot be sanitized.

Mop and sanitize floors immediately after backups -- for your family's sake.

Sewage backups are messy, smelly occurrences that leave your home and your belongings in shambles. Exposure to waste water can cause health problems for you and your family since bacteria and parasites live in sewer water. Any contact, even breathing in the odor, can cause skin irritations, allergic reactions and breathing problems. To minimize damage to your home and your health, you must act fast when dealing with sewer backups.

Step 1

Put on rubber boots, rubber gloves and a face mask to protect yourself from the sewer water. Place fans and a dehumidifier in the room where the sewer backup took place. Mop up and remove as much of the sewage water as possible, to make the rest of the clean up easier.

Step 2

Fill a bucket with hot water, then add 2 to 3 tsp. of dish detergent. Wash the tile floor with the detergent solution, using your mop. Be sure to get hard-to-reach areas, such as corners and around cabinets. Do not rinse.

Step 3

Mix 1 gallon of hot water and 1 cup of chlorine bleach in a bucket. Wet the mop with the solution and thoroughly mop your tile floor. Again, be sure to clean hard-to-reach areas. Rinse your mop for several minutes under hot running water.

Step 4

Pour hot water into a clean bucket and wet the mop. Rinse the floor with the mop.

Step 5

Leave the fans and dehumidifier in the room to help dry the floor.

Step 6

Disinfect the floor a second time, using a new solution of bleach and water, once the floor is dry. You should always wash surfaces at least twice after they have come in contact with waste water
