NASSCO Report – Trenchless Technology Solves a Homeowner’s Nightmare

Sewer problems can be a homeowner’s worst nightmare. The inconvenience, mess, and expense can quickly escalate, leaving families displaced and frustrated. However, innovative trenchless solutions are emerging to tackle these challenges head-on, offering homeowners a ray of hope even in the most-dire of situations.

Recently, a homeowner was faced with a distressing dilemma. Their home had been plagued by frequent backups, causing significant inconvenience and disruption to their daily lives. Upon investigation, the root of the problem was identified: a deteriorating cast iron section of the sewer line, extending from the basement to the transition point where it met clay piping. Heavy scale and debris had accumulated within the line, severely impeding the flow of wastewater and leading to recurrent backups. The homeowner’s frustration was visible as they recounted their ordeal of enduring backups every other week, forcing them to seek refuge elsewhere until the system would finally drain.

Confronted with this challenge, Savy & Sons recognized the urgent need for a swift and effective solution. Traditional methods of sewer repair, involving excavation and replacement, would have entailed extensive disruption to the homeowner’s property, not to mention the considerable time and cost involved. Because of the basement location of the pipe, a cured-in-place pipe (CIPP) solution was recommended to avoid damage to walls and to minimize disruption to the family.

The implementation of CIPP lining involved the insertion of a flexible liner saturated with resin into the existing sewer line. Using a method akin to pipe-in-pipe installation, the liner is then inflated and cured in place, forming a seamless, durable new pipe within the old one. For this project Savy & Sons used ultraviolet (UV) light to expedite the curing process of the resin-saturated liner, resulting in faster project completion and enhanced durability of the rehabilitated pipe. By harnessing UV light technology, the team was able to achieve precise control over the curing process, ensuring uniform hardening of the liner material without the need for excavation.

The project included relining 73 ft of 6-in. deteriorating cast iron sewer line with CIPP. Despite the challenges posed by the heavy scale and debris within the line, the project was approached with precision and expertise, determined to provide the homeowner with a long-lasting solution to their sewer woes.

The outcome of the project surpassed the homeowner’s expectations. With the CIPP seamlessly integrated into the existing sewer line, the homeowner experienced an immediate and dramatic improvement in their plumbing system’s functionality. The once-frequent backups became a thing of the past, providing the homeowner with much-needed peace of mind and restoring normalcy to their daily routine. No longer forced to endure the inconvenience of backups or seek alternative accommodations, the homeowner could finally reclaim their home and resume their lives without fear of recurring sewer issues. Beyond the immediate benefits to the homeowner, this project underscores the transformative potential of trenchless technology in the realm of sewer repair.
