Key Takeaways:

  • Keep people and pets away from contaminated areas, especially where electrical hazards are present.
  • Stop using plumbing and call professionals to address the sewage, property damage, and source of the backup.
  • Professional cleanup removes contamination, cleans and disinfects affected surfaces, and thoroughly dries the area.

If sewage backs up into your home, keep people and pets away from the affected area. Even water that appears clear or clean may contain harmful bacteria and other contaminants. Stop using anything that sends more water down the blocked drain, including toilets, sinks, showers, tubs, dishwashers, and washing machines. Then, contact the appropriate professionals.

Who to call first:

  1. An electrician or utility company if standing water creates an electrical risk.
  2. A restoration company to address sewage contamination and property damage.
  3. A plumber or septic professional to find and stop the source of the backup.
  4. Your insurance company to report the damage and confirm coverage requirements.

Clearing a sewer blockage or addressing a septic problem stops the source, but it doesn’t address the contamination left behind. Valley Restoration provides sewage backup cleanup throughout Southern Idaho, including the Wood River Valley and Magic Valley. Here’s what to do after a backup, when to call a professional, and what the cleanup process involves.

What to Do Immediately After a Sewage Backup

If sewage backs up into your home, focus on keeping individuals safe and limiting further damage. Take the following steps without entering the contaminated area.

1. Keep People Away From the Affected Area

Make sure children, pets, and other occupants are away from affected rooms, and avoid tracking contaminated water into clean areas. If there is an electrical risk, stay out and contact an electrician or utility provider as outlined above.

2. Stop Using Plumbing and Get the Source Assessed

Stop using toilets, sinks, showers, tubs, dishwashers, washing machines, or anything else that sends more water down the blocked drain.

Call Valley Restoration immediately to begin proper containment and identify the service providers needed to address the cause. Depending on the source, a plumber, septic professional, or sewer utility may need to make repairs while Valley Restoration begins containment and extraction.

Shutting off the water main may not stop a sewer backup. If you have a septic system, contact a professional for an assessment before scheduling a pump-out, since pumping may not resolve the root cause.

3. Document What You Can Safely See

From a safe location, photograph visible damage and record affected rooms and belongings. Contact your insurer and, if applicable, your landlord, but don’t delay urgent protective work to gather documentation.

Valley Restoration documents the loss during cleanup and provides your insurer with photos, moisture readings, and the scope of work needed for the claim.

Can You Clean Up a Sewage Backup Yourself?

Water damage falls into three categories based on contamination levels:

  • Category 1 (Clean Water): Water from sanitary sources, such as a broken supply line, with minimal contamination.
  • Category 2 (Gray Water): Water containing significant contamination, such as discharge from washing machines or dishwashers.
  • Category 3 (Black Water): Highly contaminated water, including sewage backups, floodwater, and water containing harmful bacteria, viruses, or other pathogens.

Sewage backups fall under Category 3, the most hazardous classification, and require professional sewage damage cleanup. Trained restoration crews use protective equipment, containment procedures, and specialized cleaning methods to safely remove contamination.

Hidden contamination, electrical hazards, and affected materials make DIY cleanup unsafe. Avoid flushing toilets, adding drain chemicals, using a household vacuum, or assuming the area is clean once the odor disappears.

What Professional Sewage Backup Cleanup Involves

Professional sewage backup cleaning focuses on removing contamination, drying affected areas, and determining what can be safely restored.

Assess the Damage and Control Further Contamination

Professionals identify affected areas and materials and coordinate repairs at the source. The contamination may extend beyond visible standing water.

Extract Sewage and Evaluate Damaged Materials

Crews remove sewage and evaluate contaminated materials. Anything affected by sewage (Category 3) must be removed. They then remove carpet, padding, insulation, and other absorbent materials for disposal.

Clean and Disinfect Salvageable Surfaces

Professional crews first clean salvageable surfaces to remove contamination. Then they disinfect them using products suited to each surface and follow label instructions.

Dry, Check Moisture, and Plan Repairs

Drying equipment and moisture monitoring help determine when affected areas are ready for repairs. Reconstruction may continue after sewage cleanup and drying are complete.

What Causes Sewage Backups, and How Can You Reduce the Risk?

Sewage backups can result from blockages, damaged lines, overloaded sewer systems, or septic problems. Spring snowmelt and saturated or frozen ground can also strain sewer lines and septic systems in the Wood River and Magic Valleys. Slow drains, gurgling, odors, and wastewater backing up through fixtures also signal problems.

Proper waste disposal, professional inspections, and, where appropriate, a backwater valve reduce the risk. Septic system owners should also schedule routine maintenance.

What Affects Sewage Backup Cleanup Costs?

Sewage backup cleanup costs depend on the affected area, damaged materials, contamination spread, access, disposal, drying, and repairs. A restoration professional will assess the damage and provide an estimate, while a plumber or septic professional may charge separately to repair the source.

Your insurance policy and the cause of the backup determine coverage. You can also explore restoration financing options for additional payment flexibility.

Sewage Backup Cleanup FAQs
