How sewage backup cleanup is handled, step by step
- 1
Contain
Barriers and protective gear first.
- 2
Remove
Extract sewage and bag porous materials.
- 3
Treat
Clean and apply antimicrobial at its dwell time.
- 4
Dry
Dry the structure to a dry reference.
Sewage carries bacteria and viruses that are not visible and do not dry out. Under the S500 standard it is Category 3 from the first minute, and porous materials it touched are removed, not dried in place.
Why sewage backs up
- Roots and grease blocking an older clay or cast iron sewer lateral
- Heavy rain overloading sewers and pushing water up floor drains
- Collapsed or sagging pipe under the house
- Items flushed that should not be
How sewage cleanup is done
The crew wears gloves, boots and respirators and sets containment so contamination does not spread through the house. Standing sewage is extracted. Carpet, pad, drywall and insulation above the waterline that the sewage touched come out and are bagged. Hard surfaces are cleaned, then treated with an EPA-registered antimicrobial left on for its labeled dwell time, and only then does drying start.
Keep the household away from it
Children, pets and anyone with a weak immune system should stay out of the area. Do not run fixtures that drain into the same pipe until a plumber clears it. If the water came in from outside during a storm, see flood cleanup, which is handled the same way.

- Water category and class of loss set on day one
- Moisture map and dry reference readings before drying
- Daily moisture and psychrometric logs
- Equipment out only when readings are within 2 to 4 points of dry
