What sewage & biohazard cleanup covers:
The crew checks for electrical and slip hazards, puts on protective equipment and seals off the affected area so sewage does not spread.
Standing sewage is pumped or scooped out, and the contaminated area is mapped to see how far the liquid traveled.
Liquid is removed first, then anything that cannot be cleaned, such as soaked flooring and wall board.
Hard surfaces and framing are cleaned and disinfected, odor is treated, and the crew checks the area before it is cleared for use.

Watch for a rotten-egg or sewer smell, wet spots or stains on floors and walls, unusually green grass over a pipe, and multiple drains backing up at the same time. If any of these show up, keep people away from the area and have the cause checked.
Usually not. Carpet and padding soak up Category 3 water and cannot be reliably made safe, so they are cut out and discarded. Hard surfaces, sealed wood and items in closed containers can often be cleaned and kept.
Yes. Commercial sewage cleanup in restaurants, offices, shops and apartment buildings follows the same biohazard steps, with added attention to keeping part of the building usable and to documentation for managers and insurers.
Treat it as raw sewage. Keep people out of the bathroom, stop using the fixture and call for cleanup. The liquid can reach under flooring and into walls, so a crew checks beyond the visible puddle.
Concrete is porous, so sewage soaks in. The surface is scrubbed, rinsed and treated with a disinfectant, and the wash water is collected rather than spread. Stubborn odor may need a second round of treatment.
If sewage is still coming up, a plumber may need to stop the source. If sewage is already on the floor, a cleanup team can start containing it at once. Many property owners call both, and it does not matter much which is first. Sewer backup companies and plumbers often work one after the other on the same job.
