Sewer line repairs are essential to maintaining plumbing systems and preventing extensive damage. Over time, sewer lines can experience issues such as blockages, leaks, or corrosion, which can lead to costly repairs and disruptions. These issues require necessary action to ensure the system functions smoothly and prevents further damage.
There are different sewer repair methods available, including traditional and trenchless. The traditional method involves excavation to replace damaged pipes, which can be a labor-intensive and disruptive process. On the other hand, trenchless methods like pipe bursting, CIPP, and sliplining offer less invasive solutions, minimizing surface disruption. Epoxy pipe coating is another non-invasive method that seals leaks and prevents corrosion, while sewer jetting uses high-pressure water to clear blockages and clean pipes.
Choosing the right method depends on the severity of the damage, pipe material, cost, and desired disruption level. Each method offers distinct benefits suited to different needs and situations.
Traditional Method
The traditional method of sewer line repair, also known as excavation or open trench repair, involves digging a trench to replace damaged pipes. It is typically used for extensive damage that requires full pipe replacement. This method is best suited for situations where the damage is widespread and cannot be effectively addressed using trenchless methods. For example, if a sewer system has significant sections of damage due to age or environmental factors, traditional excavation is often the most viable solution.
The price range for this method is somewhat costly, falling within the range of $3,000 to $6,000, depending on the severity of the damage and the area being excavated. The process also requires heavy machinery, manual labor, and surface restoration, adding both time and cost. However, traditional repairs are often necessary when accessibility to the pipes is limited or when trenchless methods are not suitable due to the condition of the existing pipes.
Trenchless Method
The trenchless method is an advanced, less invasive technique for repairing or replacing underground pipes without the need for extensive excavation. Compared to traditional, trenchless repair uses cutting-edge technology, such as pipe bursting and sliplining, to minimize disruption to the landscape and reduce repair time by up to 50%. On average, the cost ranges from $1,500 to $12,000, or $60 to $250 per linear foot, depending on factors like pipe length and the specific method used. While the initial cost may seem higher, trenchless methods are more cost-effective in the long run.
Different trenchless methods include:
- Pipe Bursting
- Cured-In-Place Pipe Lining (CIPP)
- Sliplining
- Epoxy Pipe Coating
- Sewer Jetting
Pipe Bursting
Pipe bursting is a trenchless repair method that replaces severely damaged or collapsed pipes by pulling a new pipe through the existing one, causing the old pipe to burst and expand. It is ideal for large-diameter pipes, pipes located in hard-to-reach areas, or full pipe replacement, offering easy installation without extensive excavation.
Compared to traditional methods, pipe bursting is faster and requires less space, reducing repair time by 30-50% on average. This method is cost-effective, minimizing disruption to the surrounding area while delivering long-lasting results. Pipe bursting is especially beneficial for large-scale projects or severely damaged pipes that need complete replacement.
Cured-In-Place Pipe Lining (CIPP)
A highly effective and non-invasive method for rehabilitating damaged pipes is Cured-In-Place Pipe Lining (CIPP). This process involves inserting a flexible, epoxy resin-coated liner into the damaged pipe, which is then cured using heat or UV light to form a new, durable pipe within the old one.
CIPP is effective for sealing leaks, restoring water flow, and strengthening the pipe structure. It is particularly useful in urban areas or locations where traditional excavation would cause significant disruption or incur high costs. The cost typically ranges from $30 to $700 per linear foot, and the process can take between 12 to 24 hours to complete. The newly lined pipes can last 50 years or more, providing long-term benefits and reducing the need for frequent repairs.
Sliplining
Sliplining is a trenchless technique where a smaller, flexible pipe is inserted into an existing damaged pipe, effectively renewing the sewer line. This method is ideal for situations where digging would be challenging or when the original pipe is mostly intact but needs reinforcement to restore its functionality.
The process involves inserting a new pipe, often made from high-density polyethylene (HDPE), into the old pipe and sealing the space between the two pipes to prevent leaks and maintain consistent flow. The cost for sliplining typically ranges from $135 to $150 per foot, though the price may vary based on pipe diameter, length, and job complexity.
Epoxy Pipe Coating
Epoxy pipe coating is a highly effective method for restoring damaged pipes by applying a special resin to their interior. The resin bonds to the pipe’s surface, creating a smooth, durable, corrosion-resistant layer that seals leaks and prevents further deterioration.
This technique is especially beneficial for pipes that are still structurally sound but need additional protection, such as those in older systems or exposed to harsh environmental conditions. Offering a more affordable solution than full pipe replacement, epoxy coating typically costs between $80 to $250 per linear foot and extends the lifespan of pipes by 10-15 years.
Sewer Jetting
Sewer Jetting, or hydro jetting, uses high-pressure water to clear blockages, clean pipes, and prevent future buildup. This effective method helps maintain the flow of wastewater and resolves stubborn clogs that traditional methods cannot address. It is also the perfect option to remove blockages in just a few hours and is especially useful for properties with older pipes or those prone to tree root intrusion.
Often used for routine maintenance, sewer jetting is typically recommended once every 1 to 2 years to keep pipes clean and functioning efficiently. Additionally, sewer jetting acts as a preventive measure, reducing the risk of costly repairs or system failures. The cost associated with sewer jetting generally ranges from $250 to $800, depending on the severity of the clog and the system’s complexity.
Traditional vs Trenchless Sewer Line Repair
Traditional and trenchless sewer line repairs both address pipe damage but differ significantly in terms of approach, cost, disruption, and overall efficiency. While traditional repairs require extensive excavation and are more time-consuming, trenchless methods offer a faster, less disruptive solution with reduced labor costs.
For a more detailed explanation, here is a side-by-side comparison of Traditional vs Trenchless Sewer Line Repair:

Choose the Right Sewer Line Repair Method
Answer the following questions to find the best sewer line repair method based on your needs.
Causes of Sewer Line Problems
Sewer line problems can arise from a variety of natural and human-made causes, including tree root intrusion, pipe corrosion, or clogging. Understanding the root causes of sewer backup is crucial, as it directly influences the repair method chosen.
- Tree Roots Intrusion: Tree roots naturally seek moisture and can invade sewer pipes, causing significant damage over time. As roots grow, they can block the flow of waste and even crack or break pipes. This intrusion is particularly problematic for older pipes, leading to blockages and potential system failure. For this, sewer jetting or pipe bursting is commonly used to clear roots and replace severely damaged sections of the pipe. CIPP is also effective for pipes with minor cracks caused by roots.
- Pipe Corrosion: Over time, sewer pipes can corrode due to exposure to water, chemicals, and environmental factors. Pipe corrosion weakens the pipe structure, leading to leaks, reduced flow, and eventual pipe failure. It is a common issue in older systems, especially those made of metal. Epoxy pipe coating is the perfect solution for this as it prevents leaks and protects against further corrosion.
- Clogging and Blockages: Clogging and blockages often occur when debris, grease, or foreign objects obstruct the flow of waste in the pipes. These blockages can cause backups and poor drainage, leading to potential health hazards such as contamination of water supplies or sewage backup in homes. If left unchecked, they can cause significant damage, leading to the need for full pipe replacement. For its repair, sewer jetting stands as the best option, followed by pipe bursting or CIPP.
- Shifting Soil or Ground Movement: Shifting soil or ground movement can misalign sewer pipes, causing them to crack or break. This can occur due to natural events such as earthquakes, floods, or even heavy traffic, or human activities like construction. The misalignment can lead to leaks and compromised pipe integrity, resulting in wastewater leakage and potential flooding of the surrounding area. To counter this, trenchless methods such as pipe bursting and sliplining can be effective in repairing misaligned pipes without significant disruption to the area.
- Aging or Deteriorating Pipes: As pipes age, they deteriorate due to constant wear and environmental factors, such as extreme temperatures and water pressure. Aging pipes are prone to leaks, fractures, and bursting, especially in older neighborhoods with outdated systems. These issues can lead to frequent sewer problems and costly repairs if not addressed promptly. CIPP and epoxy pipe coating are excellent methods for rehabilitating aging pipes without full replacement, adding years to their lifespan.
