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 over 2,000 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 thirty 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.
