Rising water from rivers or streams
The reason that these situations differ from fresh water is that the water contains pathogenic, fungal, and viral contamination that is a severe health risk. The first step in remediating a loss such as this is safety for both you, the occupant, and our trained personnel. The technicians have received immunizations and wear extensive Personal Protective Equipment (P.P.E.) to protect themselves against exposure. Depending on the severity and the location of the contamination, the occupants of the affected structure may have to be relocated until the damage is contained. Once safety concerns have been addressed, the next step is to remove any and all porous materials that have been affected. This would include wood, sheetrock, plaster, carpet, linoleum, and any other material that can absorb moisture and dispose of it. Next is to thoroughly rinse all non-porous materials with a biocide solution to kill any remaining bacteria.
This is a brief overview of the procedures used and as with any remediation protocol, there will always be "variables". Sewage remediation is not inexpensive to control, but the cost in dollars as well as human health problems can significantly escalate if not handled properly.
