Top Causes of Sewage Backups and How to Prevent Them

Sewage backups are one of the most unpleasant and hazardous problems homeowners and businesses can face. They not only cause property damage but also pose serious health risks due to the harmful bacteria and pathogens in raw sewage. At J. Brian Day Emergency Services, we understand the urgency and importance of preventing these issues before they escalate into major disasters. In this article, we’ll explore the top causes of sewage backups and provide actionable tips to help you prevent them.


1. Clogged Pipes

One of the most common causes of sewage backups is a blockage in the plumbing system. Everyday items like grease, hair, soap residue, and non-flushable items can accumulate over time, leading to clogs in pipes and sewer lines.

How to Prevent It:

  • Avoid pouring grease or cooking oils down your drains; instead, dispose of them in a container.
  • Install drain screens to catch hair and debris.
  • Educate household members to only flush toilet paper and human waste—no wipes, feminine hygiene products, or other items.

2. Tree Root Intrusions

Tree roots are naturally drawn to moisture, making sewer lines an attractive target. Over time, roots can penetrate pipes, causing cracks and blockages that disrupt the flow of wastewater.

How to Prevent It:

  • Avoid planting trees or shrubs near sewer lines.
  • Schedule regular inspections and maintenance to identify root intrusions early.
  • Consider using root barriers or chemical treatments to deter root growth near pipes.

3. Aging Sewer Systems

Older homes and businesses often have aging sewer lines made from materials like clay or cast iron, which are prone to corrosion, cracks, and collapse. As these systems deteriorate, the risk of backups increases.

How to Prevent It:

  • Schedule professional inspections to assess the condition of your sewer lines.
  • Upgrade aging sewer systems with modern, durable materials like PVC.
  • Invest in trenchless sewer repair technology for a less invasive upgrade process.

4. Heavy Rainfall and Flooding

Excessive rain or flooding can overwhelm municipal sewer systems, forcing water and sewage back into homes and businesses through drains and toilets. This is especially common in areas with combined sewer systems.

How to Prevent It:

  • Install a backwater valve to prevent sewage from flowing back into your property during heavy rain.
  • Keep gutters and downspouts clear to ensure proper drainage away from your foundation.
  • Work with local authorities to address overburdened municipal sewer systems if necessary.

5. Sewer Line Damage

Physical damage to sewer lines can occur due to shifting soil, construction activities, or heavy equipment passing over buried lines. These disruptions can lead to leaks, blockages, and backups.

How to Prevent It:

  • Before starting construction or landscaping projects, call utility services to locate underground sewer lines.
  • Reinforce vulnerable sewer lines with protective measures during major projects.
  • Address minor cracks or damage promptly to prevent larger problems.

6. Flushing Non-Biodegradable Items

Items like wet wipes, paper towels, and hygiene products often labeled as “flushable” do not break down in the sewer system. These items can cause severe clogs and contribute to backups.

How to Prevent It:

  • Use trash bins for disposing of non-biodegradable materials.
  • Post reminders in bathrooms to discourage flushing inappropriate items.
  • Switch to biodegradable or septic-safe products where applicable.

7. Improper Disposal of Grease

When grease and oil are poured down the drain, they may seem harmless in liquid form. However, as they cool, they solidify and stick to the walls of pipes, creating significant blockages over time.

How to Prevent It:

  • Let grease cool and solidify, then dispose of it in a sealed container.
  • Use strainers in kitchen sinks to catch food particles and prevent them from entering the drain.
  • Educate all household members about the dangers of grease disposal in plumbing.
