Health concerns related to popular pipe-fixing method

A recent article in USA today highlights the danger of a popular method used in trenchless sewer repair – Cured-in-place pipe lining, also known as CIPP.  The article reports numerous people have gotten sick from the fumes.

Cured-in-place pipe lining is a trenchless method of sewer line repair.  This process has gained popularity because it is less invasive,  often less expensive, and completed faster than other sewer repair methods. The process inserting a liner inside an existing pipe that is then inflated and heated to harden. This curing process in essence creates a new lined pipe inside of the old one.  While it does usually seal off any holes or cracks, it does not eliminate any bellies or large offsets like conventional replacement or trenchless does.

The article cites “noxious fumes created during the process can escape the job site and sicken people in their homes, schools and businesses.”

There are several alternatives to CIPP, here are some of the options:

Traditional excavation and replacement involves excavating and removing the damaged pipe and replacing it with a new pipe. While it can be more invasive and disruptive compared to CIPP, it allows for complete inspection, repair, and replacement of the damaged pipe. It may be necessary when the existing pipe is severely damaged, has a "belly" in it, or has collapsed, and CIPP is not a viable option.

Pipe bursting can be an effective alternative to excavation and replacement, as it allows for the installation of a new pipe without complete excavation. However, it requires access points at both ends of the pipe and may not be suitable for all types of pipe damage or configurations.
