A sewage backup is not just an inconvenience—it’s a serious health and safety hazard. Sewage contains harmful bacteria, viruses, and fungi that can spread quickly if not handled correctly. Whether in a home or business, knowing how to respond is critical to protecting both people and property.

 

1. Put Safety First

The first step is ensuring the safety of everyone in the affected area.

• Keep people and pets away from contaminated spaces.

• Shut off electricity to reduce the risk of shock.

• Wear protective gear such as gloves, boots, and masks if you must enter the area.

• Avoid direct contact with sewage water.

2. Stop the Source if Possible

If it’s safe, try to identify and stop the source of the sewage backup. For example, shutting off water flow or contacting your utility provider may help reduce additional contamination.

3. Call in the Professionals

1. Assessment – Inspecting the property and developing a cleanup plan.

2. Containment – Preventing contamination from spreading to unaffected areas.

While some sewage backups are unavoidable, preventive steps can reduce your risk:

• Schedule regular plumbing and sewer line maintenance.

• Dispose of grease, wipes, and other non-flushable items properly.

• Install backflow prevention devices.
