Sewage carries bacteria and viruses, so it is never treated like a clean leak. The work is staged to keep contaminated water out of clean rooms, and anything porous that touched it is usually removed instead of cleaned. Larger events overlap with the flood damage cleanup page, since floodwater is also black water.
Where the backup starts
A blocked drain, a failed pipe or an overloaded sewer can push wastewater up through floor drains, tubs and toilets. Ventura County Waterworks District No. 16 provides sewer service to the historic town center, so a backup there is worth mentioning when calling for help.
How the area is made safe
Plastic sheeting seals doorways, air scrubbers filter the air and the crew wears gloves, boots and respirators. Standing water is pumped out, then carpet, pad and wet drywall are bagged and carried out. Hard surfaces are scrubbed and treated with disinfectant. Tubs, sinks and floor drains are checked as well, since contaminated water can sit in traps and pipes after the main cleanup.
