The sight of a sewage backup is never pretty and flooding resulting from sewage backups can cause extensive damage to a property. Sewage contains contaminants like bacteria, fungi, parasites, or viruses, making the sewage backup cleaning a health risk as well. Not only is the restoration job dangerous, but moisture may hide behind walls and further problems like mould growth can follow. Calling a professional restoration company is the best way to deal with a sewage flood in a basement. Yet, here’s what property owners can do to mitigate the damage in their basement before the restoration team arrives:

- The flooded area should be evacuated. Sewage contaminants are hazardous to pets as well.
- The electrical power in the flooded area should be turned off. Electrical wires or appliances might come in contact with standing water or wet materials.
- Caution should be exercised when attempting to turn off the main circuit breaker if it’s in the basement. Electrical devices that were touched by water can be dangerous.
- Those who plan to walk through sewage water should wear protective clothing like a facemask, eyeglasses, gloves, and rubber boots.
- The valve for the main water line of the property should also be shut off. Here’s [how to shut off utilities during a disaster](https://www.puroclean.ca/blog/how-turn-utilities-when-disaster-strikes?hsLang=en).
- The insurance company must be notified about the sewage backup. This type of flooding is not covered by standard homeowners insurance, unless extra endorsements for sewers and drains are purchased.
- Also to be notified is the municipal authority or sewer department if the property is connected to a public sewer.
- The water supply system in the property should not be used (e.g. flushing toilets or drain tubs and sinks) until the backup problem is fixed.
- Windows and doors should be opened to let fresh air in and ventilate the area.
- Chlorine bleach can be added to the standing water to disinfect it a little.
