Defining Sewer Lateral, Sewer Main, and Sewer Line

A sewer main refers to a pipeline typically situated within streets or designated rights-of-way, responsible for conveying sewage from numerous residences and structures to the wastewater treatment facility. On the other hand, a sewer lateral denotes the brief pipe segment extending from the sewer main to either the curb line, property boundary, or the point where the building sewer links up. The sewer line often refers to the pipeline that transfers wastewater from a home to the sewer main. 

First, Let’s Look at Some of the common Reasons for Sewer Lines to Backup

Here are the culprits behind sewer line backups, a hidden menace lurking beneath our homes:

Tree Root Intrusion

A common issue associated with sewer lines is tree root intrusion. Tree roots naturally seek out water sources, including sewer lines. Over time, roots can infiltrate cracks or joints in sewer pipes, causing blockages and backups. As roots expand, they can apply force to the pipes, leading to structural damage and obstruction of wastewater flow. This intrusion often necessitates costly repairs and maintenance to restore proper functionality to the sewer system. Regular inspection and proactive measures are essential to mitigate the risk of tree root intrusion and ensure the longevity of sewer infrastructure.

Pipe Corrosion

Aging sewer pipes made of cast iron or clay are susceptible to corrosion, a process in which the material deteriorates due to chemical reactions with the surrounding environment. Corrosion can gradually weaken pipe walls, leading to cracks, breaks, or even collapses in severe cases. As corrosion progresses, the sewer pipe’s structural integrity diminishes, making it more vulnerable to damage and failure. Moreover, debris or sediment can easily accumulate within these compromised pipes, exacerbating blockages and increasing the likelihood of backups and sewage spills. 

Solid Object Accumulation

Flushing inappropriate items down drains or toilets can lead to blockages within sewer lines. Common culprits include sanitary wipes, paper towels, feminine hygiene products, and grease. When these solid objects accumulate within the pipes, they can create clogs that restrict the wastewater flow, ultimately causing backups.

Heavy Rainfall or Flooding

Excess water can overwhelm sewer systems during heavy rainfall or flooding, leading to backups. In combined sewer systems where stormwater and sewage share the same pipes, the influx of rainwater can exceed the system’s capacity, causing sewage to back up into homes or overflow onto streets.

Structural Defects

Sewer lines may develop structural defects due to various factors such as poor installation practices, ground shifting caused by geological processes or construction activities, and soil settlement over time. These defects encompass a range of issues, including misaligned pipes, sections where the pipe has sagged or “bellied,” or segments with improper slope gradients. These structural problems disrupt the smooth flow of sewage within the pipe, leading to backups, potential property damage, and health hazards due to sewage spills or backups. Detecting and addressing these structural defects early through regular inspection and timely repairs are essential to prevent further deterioration and ensure the proper functioning of the sewer system.

Under What Conditions Does the City Assume Responsibility for Sewer Lines?

Cities typically bear responsibility for maintaining, repairing, and operating sewer mains within their jurisdiction. This responsibility encompasses a range of tasks aimed at ensuring the proper functioning and integrity of the sewer infrastructure. The city is responsible for regularly inspecting sewer mains to identify any signs of deterioration, blockages, or structural defects. When necessary, they must undertake repairs or replacements to address these issues promptly, minimizing the risk of sewage backups, spills, and environmental contamination. 

Additionally, the city is tasked with implementing preventive measures such as root control programs to mitigate tree root intrusion and corrosion prevention strategies to prolong the lifespan of sewer mains. Furthermore, they must respond to emergencies swiftly, such as sewer line breaks or collapses, to minimize disruption to residents and businesses while safeguarding public health and the environment. Overall, the city plays a crucial role in ensuring the efficient and reliable operation of sewer mains to maintain the health and well-being of the community.

The Time Homeowners Take Charge for Sewer Line Responsibilities

Determining the homeowner’s responsibility in maintenance, sewer line backups, and repairs hinges on several key factors. Typically, homeowners must maintain the portion of the sewer line extending from their property to the main municipal sewer line. It includes routine maintenance tasks such as preventing clogs and addressing minor issues within their property’s plumbing system. 

In the event of sewer line backups caused by issues within the homeowner’s property or their portion of the sewer line, the responsibility for repairs falls on the homeowner. However, if the problem originates from the main municipal sewer line or public sewer system, the city or municipality is usually accountable for addressing and resolving the issue. Understanding these distinctions is vital for homeowners to navigate sewer-related problems effectively and guarantee timely repairs when necessary.

Understanding Upper vs. Lower Lateral Pipes and Its Key Differences

Sewer laterals serve as the underground conduits linking household wastewater to the primary sewer main located in the street. While homeowners are accountable for maintaining their sewer laterals, issues with the public sewer main line fall under the jurisdiction of the city or municipality.

Sewer laterals come in two varieties: upper laterals and lower laterals. The upper lateral constitutes the segment of the residential sewer system spanning from the residence to the property line, typically restricted by the curb or sidewalk. Conversely, the lower lateral encompasses the section of residential plumbing extending from the property line to the public sewer main line in the street.

Despite the misconception among many homeowners that responsibility ends at the property line, the maintenance and repair of lower lateral piping remain their obligation in most cases. Repairing lower laterals can be significantly more expensive than other plumbing repairs due to the potential necessity of excavating the street or sidewalk.

Strategies for Avoiding Sewer Line Backups

Discover effective strategies to prevent the need for expensive and time-consuming sewer line repairs:

  • If you live in an older home, have your sewer line camera inspected every couple of years by a licensed plumber to catch potential issues early on.
  • Avoid flushing non-biodegradable items like wipes, paper towels, and hygiene products down the toilet.
  • Dispose of cooking oils and grease correctly to stop them from solidifying and causing blockages.
  • Be aware of the location of trees and shrubs near your sewer lines.
  • Consider professional root removal or barriers to prevent tree roots from infiltrating your sewer pipes.
  • Protect your residence from potential sewer line backup incidents by adding backwater valves to your sewer line, particularly during heavy rainfall or flooding. Regularly inspect and maintain backwater valves to guarantee they are functioning correctly.
  • Maintain proper grading around your property to prevent water from pooling near sewer lines.
  • If your sewer lines are old or prone to frequent backups, consider investing in sewer line replacement or upgrades.
  • Upgrading to modern materials such as PVC or HDPE pipes can increase the durability and longevity of your sewer system.
  • Educate everyone in your household about proper sewer line maintenance and the importance of preventive measures.

Optimizing Pipe Maintenance Efforts with Video Inspection Technology

A camera inspection can be an invaluable tool for maintaining the health of your pipes. By inserting a small camera into your pipes, plumbing professionals can thoroughly examine the condition of your plumbing system without invasive measures. This process allows them to identify possible cracks, leaks, blockages, or root intrusions lurking within your pipes. With this detailed visual assessment, homeowners can proactively address emerging problems before they escalate into costly and disruptive repairs. Additionally, camera inspections can provide homeowners peace of mind by confirming that the sewer line is in tip-top shape.
