Roadway collapses and sinkholes often seem to appear without warning. A street suddenly gives way, traffic is disrupted, and emergency crews rush to stabilize the area. But in most cases, the true cause of these failures has been developing quietly for years beneath the surface. Aging pipelines play a significant—and often overlooked—role in undermining roadways. As buried infrastructure deteriorates, it can slowly destabilize the soil and pavement above, eventually leading t

By Chris MacDonald, President – CPM Pipelines Across the water and wastewater industry, one question continues to surface: How will artificial intelligence change pressure pipe inspection and rehabilitation? Much of the concern is rooted in the idea that automation will replace people. But in the pressure pipe world—defined by complex terrain, variable hydraulics, buried utilities, aging materials, and strict regulatory constraints—there are very few tasks that can be reduced

When evaluating rehabilitation options for pressure pipelines, one of the most common questions engineers face is: what matters more—modulus of elasticity or tensile strength? The answer depends entirely on the condition of the host pipe and the structural class of liner required. AWWA doesn’t classify liners by pressure rating. Instead, liners are designated according to the structural role they play in restoring or replacing the pipe wall: Class I – Non-structural:  Corrosi

Monthly Update: September 20 – October 20, 2025 Presented by CPM Pipelines – Advancing Water Infrastructure Through Innovation Welcome back to The State of Infrastructure , our monthly report highlighting key force main and sewer main incidents from across the U.S. Between September 20 and October 20, several noteworthy events shed light on the shared challenges utilities face—aging assets, third-party construction damage, and the ever-rising cost of reactive repairs. While o

Our team recently completed a 350-foot rehabilitation project on a 10-inch diameter ductile iron pipe using the H-Series   in Northern Arizona-showcasing both efficiency and precision in pipeline renewal. Before lining, we performed a thorough cleaning and CCTV inspection of the line. During this process, we identified a few obstructions and buildup, which our crew addressed to restore the pipe to optimal condition for lining. The team cleaned the line to the best achievable
