CIPP project at Dallas water treatment plant saves city money and avoids lengthy shut down
Inland Pipe Rehabilitation (IPR) recently installed cured-in-place pipe (CIPP) to renew more than 1600 ft of water lines serving a North Dallas suburb water treatment plant. IPR installed its pressure pipe renewal system provided by RS Technik using Dow custom formulated resins.
IPR invested in the new NSF certified technology a year ago and since that time has been training its crew, going through proper approval channels, conducting demonstrations and securing pilot projects. “Overall, we are pleased with the progress we’ve made with our new installation system,” explained Joe Cutillo, president and CEO of IPR. “The average age of a broken water main is roughly 45 years and it’s estimated that nearly 25% of all water mains are older than 50 years. Since most piping systems were only designed for a 50-year lifespan, the frequency of failures is going to increase significantly in the very near future.” he added.
Until recently, conventional dig and replace was the only sure way to repair a damaged or broken water main. However with the development of the RS Technik system, combined with the CIPP installation experience of IPR, water mains can now be relined and leaks can be repaired, before a line completely ruptures.
In addition to industry approval, this fully structural solution is designed to sustain long-term internal pressures and external loads of the existing pipeline. Unlike traditional CIPP, the RS Technik process includes a computer controlled, mobile wet-out and mixing unit. This results in a faster response and consistent higher quality, with professional installation.
Now that IPR’s water main rehabilitation system is available, water districts have begun to take notice and are more seriously looking at relining their CIPP water and transmission mains as a cure to their problems. “CIPP relining has been around for a long time, and has proven itself as a cost-effective, and non-disruptive way to rehabilitate sewers,” stated Jim Rorison, IPR chief operating officer. “We knew it was only a matter of time when the process migrated into the drinking water market. And when it did, we wanted to be a part of that, but not before we know we had the right system to conduct a permanent and safe repair.” The response has to the new system has be very positive and backlog is increasing. “We have several major projects coming up later this spring and summer,” added Rorison.
