Sewage water, commonly known as black water, contains pathogenic, fungal, and viral contamination that is a severe health risk. Time and temperature are critical to health and safety concerns. Failure to remove sewage debris will result in a hazardous environment. Contact with contaminated water can cause skin infections and rashes, and if ingested accidentally via improperly cleaned hands or food preparation surfaces, these contaminants can cause nausea, abdominal pain, vomiting, and diarrhea. Types of sewage back-flow include: Floor drain backups, septic tank backups, sewage ejector backups
