Use this guide from the experts at ServiceMaster Restore to learn what you should do immediately if a sewer backup should occur at your business, plus tips on how you can prevent it from happening again.


Cleaning sewage backup can be extremely hazardous to the health of the cleaner and others who enter the property. This is why sewage backup cleaning should only be done by qualified and experienced professionals. If there are signs of sewage backup at your commercial property, call an experienced water damage restoration company immediately, so the cleanup can be done properly and professionally, and you can get back to business as soon as possible.

Water damage restoration experts know how to avoid health risks while safely removing biohazards. A properly trained and professional cleaning crew can effectively handle the following sewage clean-up tasks:

  • Remove all items that have been damaged due to the sewage backup
  • Properly discard items that cannot be salvaged
  • Properly disinfect saved materials off-site
  • Remove all water and sewage with specialty equipment
  • Dehumidify affected areas
  • Ventilate dangerous fumes and airborne particles
  • Disinfect flooring and surfaces within the ┬ácontaminated area


Sewage backup problems can be difficult to remedy, but knowing the root cause of the issue can help prevent them from happening again. Some of the most common reasons why commercial buildings experience sewer backup include:

  • Soil settlement in and around the building, putting stress on the plumbing and sewer system
  • Cracked pipes or misaligned connections and joints in the plumbing system
  • Infiltration of pipes and plumbing from tree roots
  • Grease build-up and improper flushing habits in the building
  • Irregular cleaning and maintenance, especially in high-volume commercial settings where maintenance is crucial


Contaminated water and sewage issues in your commercial building can be a serious health hazard and cause costly interruption to your business activities, but a few preventative maintenance tasks can prevent them from occurring. Follow these guidelines to reduce the risk of sewage contamination at your business:

  • Have your sewer and plumbing systems inspected at least annually
  • Use a water-pressure reducing valve to limit stress on your building's system
  • Add pop-up sewer release valves if your plumbing system does not already have them
