Trenchless Technology, the leading publication covering the trenchless marketplace, has announced the winners of its 30th annual Projects of the Year for 2022 — the most highly-coveted and prestigious trenchless industry project awards. Projects are awarded in New Installation and Rehabilitation categories.

The announcement was made today during a special live Trenchless Technology Municipal Webcast on September 22, as part of World Trenchless Day.

This year’s overall winning projects for New Installation and Rehabilitation feature the trenchless applications of horizontal directional drilling (HDD) and spin cast pipe relining.

“The entries for the 2022 Projects of the Year represent the immense diversity of projects and trenchless methodologies that the trenchless industry has to offer,” says Trenchless Technology editor Sharon M. Bueno. “The industry continues to lead the way in construction innovation and expand the boundaries of trenchless applications. Our winning projects offer just a glimpse of the incredible work and success trenchless technologies provide to improve our aging underground infrastructure. Congratulations to all!”

“We want to thank everyone who submitted their projects for consideration, making the decisions of our New Installation and Rehabilitation Committees such a difficult task,” she adds.

The Project of the Year for New Installation is North Bakken Expansion-Lake Sakakawea HDD, Watford City, North Dakota. This dramatic 15,426-ft, 24-in. HDD crossing utilized the intersect method to cross Lake Sakakawea at a depth of more than 300 ft. The purpose of the project was to construct a natural gas pipeline in order to reduce natural gas flaring in the area. The route would connect WBI’s Tioga Compressor Station near Tioga, North Dakota, with the Northern Border Pipeline Co.’s mainline at a new interconnection point south of Watford City. Above all of its challenges, this project demonstrates the crucial collaboration between the owner, WBI Energy, engineer, CCI & Associates and HDD contractor Michels Trenchless, to create a design to make this project successful.

Other projects recognized in the New Installation category are: Waterdown to Finch 63 km NPS 12 Pipeline Replacement Project, (Runner-up); PacWave South (Honorable Mention); and Dominion Energy Gainesville – Haymarket – 230kV Underground Transmission Lines (Honorable Mention).

This year’s Project of the Year for Rehabilitation is the City of Houston’s 60-in. Sanitary Sewer Spin Cast Lining. Like many of North America’s long-established metropolitan centers, the City of Houston is engaged in actively combatting its aging infrastructure problems. One such section – a 2.8-mile stretch of 60-in. reinforced concrete pipe – was found to be showing signs of deterioration in 2018. The problem: much of the pipe was under the heavily traveled Houston METRORail Red Line and shutting down the trains was not an option. Offset manholes meant that cured-in-place would not do. Instead, Houston’s Wastewater Operations Branch looked to a spray-applied geopolymer mortar structural rehabilitation solution.

Other projects recognized in the Rehabilitation category are: 66-in. Trunk Sewer Rehabilitation Project, Napa, California (Runner-up); M29 Outfall Improvements, Pittsburgh, Pennsylvania (Honorable Mention); and Stamford Interceptor Phase II Trunk Sewer Rehabilitation, Niagara Region, Canada (Honorable Mention).

Winners are featured in the October 2022 issue of Trenchless Technology and will be formally recognized at the 2023 NASTT No-Dig Show, to be held in Portland, Oregon, April 30-May 4. Winners are chosen on the basis of technical advancement, technical complexity, milestones and records achieved, interaction and cooperation and advancement of the trenchless industry. Spearheading our Project of the Year process is managing editor Mike Kezdi, working with two committees of New Installation and Rehabilitation experts representing a cross-section of the industry.
