2024 Trenchless Technology Projects of the Year Announced

Trenchless Technology magazine, the leading publication serving the trenchless rehabilitation and new installation markers, announced the winners of the 2024 Trenchless Technology Projects of the Year.

This year’s New Installation Project of the Year is the Trans Mountain Pipeline Expansion Project in western Canada. The project stands out for its scale and technical innovation. Spanning 74 km of trenchless construction, the project tackled extreme challenges with groundbreaking techniques, including Direct Pipe, microtunneling, and directional drilling (including through extremely hard bedrock).

Runner up in the New Installation category was the First Creek Interceptor in Aurora, Colorado. Honorable mentions were the James River Crossing HDD in Hampton Roads, Virginia, and the Lake Ouachita Crossings in Hot Springs, Arkansas.

This year’s Rehab Project of the Year is the Front Street Interceptor in Harrisburg, Pennsylvania. It is remarkable for its complexity and innovation. As the first major U.S. project designed using ASCE MOP 145, it pushed the boundaries of modern CIPP design. Unique downtown waterfront location with limited access, the challenges of lining large-diameter CIPP with unusual geometry and depths of up to 20 feet, and the innovative design methodology used made this $18 million project a standout, demonstrating flawless execution from all teams involved.

Runner up in the Rehabilitation category was the Moonlight Beach Triple UV-CIPP project in Encinitas, California. Honorable mentions were the Spout Run CIPP project in Arlington, Virginia, and the South Claiborne Water Transmission Replacement project in New Orleans, Louisiana. Tags: Trenchless Technology
