What Are Sewer Trenchless Technologies?

Trenchless sewer technologies are advanced techniques for repairing, replacing, or installing underground sewer pipes without major excavation. Unlike traditional methods that require digging trenches, trenchless solutions use specialized equipment to minimize disruption to landscaping, driveways, sidewalks, and roads.

These technologies are designed to extend the life of sewer systems while reducing costs, labor, and environmental impact—especially valuable in urban areas like San Diego.

Almco offers the following trenchless sewer repair methods.

Spray Epoxy Pipe Lining

Spray Epoxy Pipe Lining

Spray Epoxy Pipe Lining

Spray epoxy pipe lining restores aging or damaged sewer and drain pipes by applying a uniform epoxy coating to the interior surface, creating a seamless, corrosion-resistant barrier.

The process eliminates the need for excavation and restores pipe integrity by sealing cracks and preventing future leaks or root intrusion, while also improving flow efficiency. This method is especially valuable in residential and commercial settings in San Diego, where traditional digging would be disruptive to landscaping and paved surfaces.

Spray-applied epoxy is effective for many repair scenarios but is not structural and is best suited for pipes in fair condition. For applications requiring greater reinforcement, such as severely deteriorated cast iron, CIPP or pipe bursting may provide more reliable longevity.

Cured-In-Place Pipe (CIPP) Lining

CIPP (Cured-in-Place Pipe) is a trenchless “pipe-within-a-pipe” repair method that rehabilitates damaged sewer, storm, or water lines without excavation. After inspecting and cleaning the existing pipe, a flexible liner saturated with epoxy or polyester resin is inserted and cured in place via steam, hot water, or UV light to form a seamless, corrosion-resistant new pipe inside the old one.

This process applies to a wide range of pipe materials, including clay and cast iron, and it avoids major disruptions to landscaping or hardscapes. CIPP is fast, often completed in hours, and cost-effective, at 40–60% less than open-cut replacement. It provides a durable repair that often lasts 50+ years with resistance to leaks.

Pipe Bursting

Pipe bursting is a trenchless replacement method that fractures deteriorated sewer lines and pulls a new HDPE pipe into place simultaneously. This method requires only two small access pits and no full-length excavation.

This high-speed solution is ideal for cracked, collapsed, or cast-iron pipes beyond repair. It preserves landscaping, speeds up completion (often within a couple of days), and reduces restoration costs. HDPE pipe is seamless and resistant to root intrusion and corrosion. It is engineered for long-term durability and typically lasts 50+ years.

Pipe bursting is an efficient and durable trenchless solution for San Diego homeowners and businesses who need a complete sewer line replacement without the mess and expense of traditional excavation.

Pros & Cons of Trenchless Sewer Technologies

While trenchless sewer technologies offer significant benefits, they also come with certain limitations. Here’s a detailed look at the pros and cons of trenchless sewer repair and replacement.

Advantages of Trenchless Technologies

  • Minimal Property Disruption. Unlike traditional excavation, trenchless methods require little to no digging, preserving landscaping, driveways, sidewalks, and structures.
  • Faster Repair & Replacement. Most trenchless sewer repairs can be completed in a single day, reducing downtime and inconvenience for homeowners and businesses.
  • Variability. It is possible to navigate 45° and 90° angles, replace entire runs of 2”, 3”, 4”, or 6” pipe, and even upsize—for example, replacing a 3” pipe with a 4” using pipe bursting.
  • Long-Lasting Solutions. Materials used in trenchless repairs, such as CIPP liners and HDPE pipe, are durable, corrosion-resistant, and can extend the life of sewer systems by 50+ years (SDR-17 about 100 years).
  • Cost-Effective in the Long Run. Although upfront costs can be higher, trenchless repairs eliminate the need for costly property restoration, making them a more economical choice over time.
  • Environmentally Friendly. Trenchless technologies reduce soil disturbance, protect tree roots, and limit waste disposal, making them a greener alternative to traditional excavation.
  • Root & Leak Prevention. Methods such as CIPP lining and epoxy coating create seamless, jointless pipes that prevent root intrusion and future leaks.

Disadvantages of Trenchless Technologies

  • Not Suitable for Every Situation. If a pipe is completely collapsed or severely misaligned, trenchless methods may not be viable, and traditional excavation may be required.
  • Access Point Requirements. While less invasive than full trenching, some methods, such as pipe bursting, still require small excavations for equipment access.
  • Pipe Size & Condition Limitations. Some trenchless methods, such as CIPP lining, work best on pipes within a certain diameter range and may not be effective on extremely deformed or collapsed pipes.
  • Limitations of Pipe Bursting Technology. If the old pipe is less than 18” deep, pipe bursting equipment cannot be used. Other underground utilities must be at least 5” away to avoid accidental damage. Pipe sections that go through the foundation must be trenched, or an alternative technique must be used.

The best approach depends on the condition of the existing sewer line, budget, and long-term goals. Consultation with an Almco sewer specialist will ensure the most effective method is selected for your needs.
