Why Vertical CIPP Lining Is The Best Method For Sewer Rehabilitation

On a macro scale, communities depend on miles of underground sewer lines to move millions of gallons of wastewater every day. On the other hand, on a micro level, residents or tenants of residential or commercial buildings rely on the building’s vertical stack pipes to direct wastewater from fixtures to the municipality’s sewer system. However, since these systems are hidden, deterioration and defects often go unnoticed until an issue arises and cause inconvenience. 

When a sewer line and vertical pipes get damaged, it can represent tremendous complications, including hazards. Also, since these pipes are designed to be out of sight, replacing or repairing them can be quite messy. 

Fortunately, new technologies and innovations in the pipe industry offer a more convenient and easier way to rehabilitate sewer lines– vertical CIPP lining. In this article, you’ll learn more about this popular method of repairing and replacing underground and vertical pipes and why it’s the best option for pipe rehabilitation. 

But first.

What Are The Common Causes Of Sewer Deterioration?

Like any other thing, sewer systems can deteriorate over time. And the cases of deterioration can range from general damage to structural fatigue. 

  • Structural fatigue due to traffic loading, soil movement, freeze-and-thaw cycle, and erosion.
  • Broken or damaged pipes due to adjacent construction, break-in taps, installation error, or cleaning. 
  • Pipe corrosion 
  • Aging pipe
  • Material decay
  • Root intrusion

Knowledge of what’s causing sewer pipes to deteriorate can help guide decision-making for rehabilitation. 

Understanding CIPP Lining

Cured-in-place pipe or CIPP lining is a recent innovation in fixing pipes. It aims to repair, rehabilitate and restore existing pipes with a trenchless process, using liquid resin and liner tubes. With this method, a worker inserts the resin-based liner through an existing pipe. The liner is then cured into place, which results in a seamless and durable ‘pipe-in-a-pipe’ solution. 

In general, CIPP lining can be used to rehabilitate any damaged or corroded pipes, from residential plumbing to municipal sewer systems. 

4 Reasons Why Vertical CIPP Lining Is The Best For Sewer Rehabilitation

Due to its several benefits, vertical CIPP lining is a preferred method for rehabilitating and restoring old and damaged sewer lines. Here are the advantages of using CIPP lining:

  • It Is A Less Invasive Approach To Repair Existing Pipelines

Generally, CIPP lining is often called a ‘dig-less’ repair method, meaning there’s no need for major excavation work to rehabilitate and replace sewer lines. This eliminates the need to dig up old sewer lines, which can ruin roads and highways and create public hazards and interruptions.

Plumbing technicians use video technologies to assess the condition of the pipes and check the damages that occurred. Once technicians have a full view of the overall state of the sewer lines, new pipes are installed into the old pipes which seals the damaged and corroded areas.  

The same process can be applied when rehabilitating vertical pipes in a building. In a traditional approach, professionals need to open or break walls to access damaged or hard-to-reach pipes. But with vertical CIPP lining, you can eliminate the chances of your property getting damaged during the restoration process.

  • It Saves Money And Time

When compared to the old, traditional methods of repairing and replacing damaged or corroded pipes, CIPP vertical lining is a faster and cheaper solution. Since CIPP lining is a less invasive and dig-less method, there’s no need to hire a big crew of workers to replace the sewer lines. Also, you don’t have to rent out large equipment for excavation or to open the walls. 

With fewer workers to hire and no large equipment needed, cities and municipalities can save on extra costs. Aside from these direct costs, CIPP lining can also save you from indirect costs from restoring roads and landscaping and a home or building’s interior walls.

In addition to saving money, CIPP lining is also time effective. Since there’s no digging required, CIPP lining can be completed within a day or more, depending on the amount of damage within the lines. With faster repair, it all goes back to saving more money in terms of labor and convenience. 

  • It Is a Safer Method Of Rehabilitation

One of the most important benefits of this sewer line repair method is that it ensures public and worker safety. 

In traditional pipe repair methods, excavating old pipes means there’s an increased risk of exposure to toxic waste material, asbestos, mold, and other potentially harmful elements.  Since CIPP lining is completed underground without excavation or opening building walls, there’s a reduced risk of exposure to these harmful elements.

  • It Is Durable And Long-Lasting

The lining solutions used in vertical CIPP liners are highly durable and are specially designed to withstand common hazards that often break and damage other pipes. What’s more, CIPP liners are installed to be a single cohesive pipe section. So, without joint pipes, CIPP lining has lower risks of worn-out damages that often occur from these connecting parts. 

When done properly, vertical CIPP lining in sewer lines can last well over decades. 


As one of the best innovations in modern plumbing technology, there’s no denying the several benefits that CIPP lining offers in rehabilitating wastewater collection systems. For one, it’s an effective solution that can rehabilitate damaged, corroded, and old pipes without the disruption, messiness, and time-consuming process of traditional repair methods. Opting for this sewer rehabilitation method can help save on cost, allowing for more efficient use of resources.
