What it is
This covers water carrying contamination: a sewer backup, a failed septic system, or flood water that has passed through either. It is a separate category of work because the contamination sets the scope, not the volume - a small backup can require more removal than a large clean-water loss.
When it is needed
Any backup through a floor drain, toilet or fixture, any septic failure reaching the building, and any water of unknown origin that has been standing. Waiting does not improve the outcome here in the way it sometimes can elsewhere, because the contamination continues to spread through porous material for as long as it stays wet.
What it typically involves
Containment comes first, then removal and disposal of porous material the water contacted - carpet, pad, insulation and drywall to a margin above the visible line. That material is discarded rather than cleaned, because contamination penetrates the pore structure and no surface treatment reaches it. Hard surfaces are cleaned and treated, and the space is dried afterward like any other water loss. Anyone working in it needs protective equipment, and the affected area stays sealed off from the rest of the building until cleaning is finished. The larger scope compared with a clean-water job of identical size is the category doing that, not an upsell.
