Options for Gas Main Replacement

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.

Engineering Innovations Emerge from Lining Challenges

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.

Eversource Evaluates Trenchless Technology

Eversource Engineers analyze PPM’s CIPL for a capstone project to rehabilitate a leaking bridge pipeline. Read about the role of trenchless technologies in Eversource’s portfolio of solutions for improving safety, reliability, repairing leaks and reducing fugitive emissions.

BEM Pipeline Assessment For Railroad Crossing

Assessing ferrous pipe walls provides critical data to determine the condition and integrity of pipelines. When a utility needed to assess a section of a 20 inch cast iron main that runs under a railroad right-of-way, Broadband Electromagnetic Probe (BEM) accurately assessed the condition and the degree of corrosion or graphitization.
