BLOG: What does 25 million feet mean?


Welcome to the newly enhanced We hope you have had an opportunity to take a look around and explore our new content, including our video library and an enhanced interactive map of our installer network.  

With this new website, it is our goal to bring you current, relevant information about the latest cured-in-place pipe industry trends and advancements.

First on tap is a dialogue about just how much customers can benefit from the vast experience gained by the industry’s leading cured-in-place pipe companies over decades of experience installing the product. In Inliner’s case, that is 25 million feet of CIPP. But, how does that translate to our clients’ needs? 


What, exactly, does 25 million feet mean?

·         It means the crews have become more efficient. When Inliner CIPP was first introduced to the market, one crew could take two to three days to install an eight-inch line. Today, the same crew can complete six to eight installations in one week. This time savings translates into minimizing inconvenience and disruption to the neighborhoods where the work is being performed, and lower costs to the respective owners.

·         It means improved installation crew composition. Through our refinement of processes, training  and the development of specialized equipment, we’ve been able to reduce our crew sizes. from 8 workers to 4.  Adhering to the philosophy of “the right tool for the right job,” our specialized tools and equipment packages contribute to the safety and efficiency of the workers at the installation site. Again, this results in lower costs to the customer and minimized disruption to the community.

·         It means advancements in resin technologies. Partnering with the technical staff of our vendors, we have developed materials, impregnation processes and transportation and storage practices to ensure the best possible product can be delivered and installed at the cured-in-place pipe job site. 

·         It means liner manufacturing improvements.  25 million feet is a lot of tube and we have embraced the opportunity to build the best product possible. Being vertically integrated and co-located with our exclusive lining supplier affords Inliner Technologies the opportunity to work directly with manufacturing personnel to develop and test new configurations of liners to more adequately meet the requirements of the individual projects. 

·         Finally, it means that we have developed solutions for a variety of customer needs. The experience provided by 18 million feet of installed cured-in-place pipe to our engineers, project managers, superintendents, and seasoned laborers, provides the foundation on which we can assess, build, plan and complete the most complex CIPP installation projects.

Here is an example from a project our Canadian licensee, Clean Water Works, performed last February:

When CWW was tapped by the Quebec Ministry of Transportation to line several storm culverts transversing a busy highway, the planning team was challenged to figure out a solution to lining these very large pipe segments without onsite access to water. The largest culvert alone was 96 inches in diameter, which would require 180,000 gallons of water to implement a traditional water inversion and cure of the liner. That would have required a minimum of 36 water tanker deliveries, just for that single tube. Although the CIPP industry has been using air inversion and steam cures for a long time, a general guideline is that pipes above 60 inches cannot be properly installed with this method due to the weight of the required thickness of that size tube. Working with our tube manufacturer, Liner Products, we developed a solution that involved using air to first invert a 37-mm liner, then pulling in a 9-mm calibration tube and inflating it against the walls of the liner and curing it by steam. The end result was the required 46mm liner with an 180,000-gallon water savings. Pretty impressive! You can read the entire case study here:

These are just a few examples of how the CIPP industry has evolved since Inliner burst onto the scene more than twenty years ago. We hope you enjoy visiting our site and come back often to learn more about advancements in the cured-in-place pipe industry.
