A sewer backup at your business can cause major disruptions, health hazards, and costly repairs. Learn how to respond fast and restore your property with help from ServiceMaster Restoration By Simons.

A Sewer Backup at Your Business? Here’s What to Do Immediately

When sewer water invades your commercial property, it’s more than just an inconvenience — it’s a serious threat to your business, employees, and customers. Sewer backups can lead to dangerous health conditions, structural damage, and lost revenue. If your business suffers a sewer backup, the first and most important step is to contact a professional water damage restoration company like ServiceMaster Restoration By Simons. We’re here 24/7 to minimize damage and get you operational again.

What Is a Commercial Sewer Backup?

A sewer backup occurs when wastewater from the city sewer line or your building’s main sewer pipe reverses flow and enters your business. This typically happens due to:

  • Heavy rain or flooding that overwhelms city sewer systems
  • Blockages caused by grease, debris, or foreign objects
  • Tree root intrusion into sewer pipes
  • A damaged or collapsed sewer line

When this happens, contaminated water can rise through floor drains, toilets, or sinks, flooding your property with dangerous black water.

What Causes Sewer Backups in Commercial Buildings?

  • Tree Roots: Roots seek moisture and can break into sewer lines, causing blockages.
  • Sanitary Main Blockage: When the city’s main sewer line is clogged, waste can back up into businesses.
  • Improper Waste Disposal: Grease, paper products, or foreign items flushed or drained can create clogs.
  • Illegal Plumbing Connections: Connecting sump pumps or drains to the sanitary sewer can overwhelm the system and cause backups.

Does Business Insurance Cover Sewer Backup Damage?

Most commercial property insurance policies do not cover sewer backup damage unless you have specifically added sewer backup coverage. Talk to your insurance agent to review your policy and ensure you have protection.

How to Prevent Sewer Backups in Your Business

  • Proper grease disposal: Never pour grease down the drain; let it cool and dispose of it in the trash.
  • Only flush approved materials: Avoid flushing paper towels, feminine products, or wipes.
  • Install a backwater prevention valve: This valve can stop sewage from backing up into your business.
  • Replace aging pipes: Modern plastic pipes are less prone to damage from tree roots.
  • Keep stormwater out of the sanitary system: Don’t connect sump pumps or French drains to sanitary lines.

Why You Should Never DIY Sewer Backup Cleanup

Sewer water (Category 3 "black water") contains harmful bacteria, viruses, and toxins. Exposure can cause:

  • Hepatitis A
  • Skin infections and rashes
  • Respiratory issues
  • Gastrointestinal illnesses

Professional restoration companies like ServiceMaster Restoration By Simons have the proper PPE, cleaning agents, and equipment to handle hazardous materials safely.
