"The conference was quite successful," said Hemphill. "It was held in junction with ECWATECH-2008, Water: Ecology and Technology, an established event that attracted large gathering of underground construction and water technology delegates. It was clear from conversations that Russians are just beginning to introduce trenchless methods as a means for installing and renewing underground infrastructure, and attendance at the technical sessions made it clear they are very interested in learning more about trenchless procedures and how they can apply them to their projects. ISTT members were impressed with their enthusiasm."

Hemphill said the event provided an opportunity for his introduction to the ISTT board and to meet with members from many nations.

"The 2008 International No Dig was John Castle's last as executive secretary," he continued. "He presided at the event and was honored for his service to ISTT. For me it was a learning experience, and I kept a low profile."

The ISTT was founded in 1986 to promote and encourage the use of trenchless technologies for the installation, rehabilitation and maintenance of underground utility infrastructure thereby reducing or eliminating excavation. ISTT currently has 22 affiliated trenchless societies, including NASTT. The newest member is Bulgaria which joined at the Moscow convention in June.

"I would say a major goal of ISTT today is to increase worldwide training in trenchless procedures," said Hemphill. "ISTT faces many of the same challenges the NASTT had during my time there, and I think my experience at NASTT and the progress we made was a factor in my selection."


Hemphill said one of his most rewarding experiences at NASTT was coordinating efforts of an HDD consortium that developed and implemented the Horizontal Directional Drilling Good Practices Guidelines.

"The HDD guidelines continue to impact our industry and became the seed for NASTT's expanded educational programs," he said, "and lead to the development of good practices guidelines for cured in place pipe (CIPP) lining procedures; pipebursting, sewer laterals and new installations which include pipe jacking, pipe ramming, pilot tube boring and other new applications."

Hemphill has more than 35 years experience in management and policy analysis in the fields of engineering and energy.
