A main line backup sends raw sewage up through the lowest drains in the house, usually a basement shower, floor drain, or toilet. That water carries E. coli, hepatitis, and other pathogens. Safe cleanup means containment, protective gear, removal of everything porous it touched, and thorough disinfection.

You get a written estimate that covers removal, disinfection, and drying before work starts.

Proper sewage remediation is methodical. Contamination is removed, every surface is disinfected, and only then does drying begin.

Liquid sewage and solids are extracted with dedicated equipment and disposed of according to local rules, not dumped down another drain.
Carpet, pad, drywall, insulation, and particleboard that touched sewage cannot be reliably disinfected and are bagged and removed.
Hard surfaces are scrubbed, then treated with EPA-registered disinfectants left on for the full contact time listed on the label.
After disinfection, HEPA air scrubbers and odor control treatments remove lingering sewage odor from the air and structure.
Cleanliness is checked, sometimes with ATP swab testing, before drying gets the area ready for rebuild.
Tell dispatch which drains are backing up and how far the sewage spread.
A local contractor calls back with an arrival window and reminds you to keep everyone away from the contaminated area.
Containment goes up first, then the pro maps the contamination and provides a written quote.
Contaminated materials are removed, surfaces disinfected, odors treated, and the area dried. The contractor may recommend a plumber to clear or camera the main line.

It is Category 3, meaning grossly contaminated. That category triggers full biohazard protocols.
Small, contained jobs may be fine. For large backups or vulnerable family members, staying elsewhere is often safer.
A very small hard-surface spill can be cleaned with gloves, boots, and a disinfectant. If sewage reached carpet, drywall, or a large area, professional cleanup is the safer choice.
Many standard policies exclude sewer backup unless you have a specific sewer or drain backup endorsement. Check your policy with your agent.
Tree roots, grease clogs, damaged pipes, and city sewer overloads are the usual culprits.
