For a cast-iron natural gas main, initial replacement options for Peoples Gas in Chicago seemed straightforward—plastic or steel pipes. Logistical, operational and system constraints led the utility to explore an alternative solution: trenchless pipe-lining technology.
Extending service life and upgrading the piping system of a University of Pennsylvania building in record time demanded strategic innovation, and swift execution. Due PPM and INTECH’s tight collaboration, the project was a success.
The 30-inch turnkey project in Brooklyn’s Gowanus Canal challenged what we thought was possible. There were several times we wondered, can it be done? There was nothing conventional about this project. The drawings showed a pipe configuration I had never seen.
After a previously installed liner failed, UV CIPP proved an ideal solution to rehabilitate a leaking 36-inch storm drain under a heavily trafficked road at a manufacturing facility in New Jersey. Interestingly, the leaking stormwater drainpipe had been lined a few years prior.
