Clean up raw sewage carefully. Raw sewage contains viruses, bacteria, human waste, chemicals, and other contaminants that are harmful to humans. Raw sewage spills come from backed-up septic tanks, burst pipes, floods, and plumbing problems. Because of the variety of chemicals in sewage, it’s important to be careful. Sewage can ruin or stain surfaces. If you know of any chemicals in the sewage that are a biohazard, contact a toxic waste removal company.
Put on rubber gloves and boots.
Plug in the wet vacuum. Vacuum up the water and sewage.
Dump the contents of the wet vacuum out into a storm drain or down a toilet. Rinse out the wet vacuum with bleach.
Pour 1/4 cup of bleach into a mop bucket. Add one gallon of water.
Dip a scrub brush into the bleach water. Place the scrub brush on the dirty surface and scrub. Dip the scrub brush in the bleach water frequently.
Allow the surface to air-dry.
Dump the bleach water down the drain.
Wash any machine-washable items in a washing machine. Wash with hot water, says the Southwest District Health website.
"Proper Sewage Clean Up Procedures," by the Southwest District Health website, recommends throwing away items that aren't washable.
Pour bleach onto the rubber boots to clean. Throw away the gloves. Wash your hands with antibacterial hand soap.
