Founded in 1990, NASTT represents more than 2,000 members throughout the United States, Canada and Mexico who all promote better and more responsible ways to manage our underground infrastructure. NASTT’s mission is to advance trenchless technology and to promote its benefits for the public and the natural environment by increasing awareness and knowledge through technical information dissemination, research and development, education and training. NASTT strives to provide a representative voice for all sectors of the trenchless technology industry. For over 30 years, the all-volunteer members of NASTT have presented non-commercial information seminars and training about these “green alternative” engineering methods to North American communities.


What is Trenchless Technology?

Trenchless technology is a progressive civil engineering process for the installation, replacement or renewal of underground utilities with no or minimal excavation and surface disruption. These innovative methods have been utilized successfully for all underground utilities including water mains, storm and sanitary sewers, gas main, electrical and fiber optics conduits. When employed in urban areas, substantial benefits are realized including dramatically reduced disruption to vehicular and pedestrian traffic, to business activities, to residential areas, and to environmentally sensitive areas. Trenchless technologies are the premier crossing options for major roads, railways, waterways as well as natural or manmade structures. In most cases, trenchless techniques will demonstrate significant cost saving benefits for municipalities and utilities over traditional open trench methods. Recent advancements in robotics have allowed trenchless technologies to provide pipe condition diagnostics never before available permitting utility owners to more accurately identify infrastructure priorities.


How can NASTT make a difference?

As NASTT continues to grow and take on new challenges, it is important for our not-for-profit society to serve and support our diverse industry partners. We proudly represent municipalities and public utilities, consultants and engineers, manufacturers and suppliers, trenchless contractors, and academia. We are proud to support 12 Regional Chapters and 18 Student Chapters. We attempt to reach out to all these groups and share with our communities the latest industry trenchless advancements and our continuing education opportunities. The many benefits of trenchless solutions for today’s infrastructure challenges will always be our strength.
