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 savings 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 which permit utility owners to more accurately identify infrastructure priorities.

Who is NASTT?

NASTT is an engineering society of individuals, public organizations and private companies with strong beliefs in the practical, social and environmental benefits of trenchless technology. Founded in 1990, NASTT represents 1,500 members throughout the United States and Canada 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 more than twenty 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.
