NASTT offers multiple in-depth, high-quality courses each year in cities throughout North America as well as virtual options.
The course content is of the highest quality as the material is thoroughly peer-reviewed for consensus-based information and noncommercialism. Attendees earn valuable Continuing Education Units for their participation, issued through the Trenchless Technology Center at Louisiana Tech University.
Many of the offerings in 2025 have been completely revised to reflect the latest advancements in the industry or are totally new courses developed from industry feedback and need.
NASTT’s updated and new Good Practices courses
Direct Steerable Pipe Thrusting Good Practices Course — NASTT’s newest course for direct steerable pipe thrusting is an 8-hour course covering good practices for design and construction. The course is ideal for owners, engineers and contractors interested in learning about DSPT technology, its applications and its limitations. The course includes a discussion of the development of DSPT including horizontal directional boring, direct pipe and prime pusher. It also includes an overview of the process and DSPT-specific equipment. Other discussion items include feasibility studies to facilitate design and construction, geotechnical considerations, geometric design, steel pipe design, workspace requirements, construction sequencing, permitting and contracting.
Laterals Good Practices Course — The NASTT Laterals Good Practices Course has been completely revamped and updated for 2025. This newly revised course was offered at the NASTT 2025 No-Dig Show in Denver for the first time. This course offers a clear understanding of the problems and relevant issues unique to sewer laterals throughout the United States and Canada. It explains available options for inspection, cleaning, evaluation and repair of sewer laterals from a public and private perspective. With the rapid advancement of trenchless technology, municipalities and contractors are looking for more solutions with less impact and disturbance to homeowners and city streets.
CIPP Good Practices Course — The all-new NASTT CIPP Good Practices Course has been updated for 2025. The course provides a comprehensive overview of gravity sewer CIPP rehabilitation from planning, through design, project implementation and verification. It also provides an overview of CIPP in pressure applications and in sewer lateral programs. Major updates in design include both the most current ASTM F1216 — Appendix X1 releases, ASCE MOP 145 and an overview of the soon-to-be-released AWWA Design Appendices for Pressure Pipe Design of CIPP. Other enhancements include environmental and safety aspects of CIPP, including the latest research on VOC management.
Horizontal Directional DrillingGood Practices Course — Recently updated, the all-new HDD Good Practices Course is based on the 2024 release of the 5th Edition of NASTT’s HDD Good Practices Guidelines. Here are some of the exciting updates you can expect from this revised course: Expanded geotechnical investigation recommendations; revised recommendations for bend radius considerations; discussion of new U.S. Army Corps requirements for HDD crossings under levees; significant changes to recommendations for guidance, surveying and tracking of HDD pilot holes; significant changes to construction considerations, including noise abatement, intersect method, drilling in rock, pipe fabrication and support and inspection of HDD projects.
Advanced HDD Good Practices Course — HDD: Calculations & Advanced Design Good Practices Course is based on advanced modules from the recently released 5th Edition of NASTT’s HDD Good Practices Guidelines. The five-hour focus on HDD design course is geared toward industry professionals who have an understanding of the basics of HDD construction. This session focuses on advanced design considerations that are specific to HDD projects. The presentation includes a detailed look at geotechnical conditions and potential risks related to ground conditions, as well as a discussion of contract document considerations. The course also includes an in-depth discussion of the various calculations that are needed to assess and mitigate risks when designing HDD crossing geometries, including hydrofracture risk analysis, pull back and pipe stress calculations for various pipe materials and settlement risk evaluations. These calculations are often required to secure permits from DOTs, railroad owners, environmental agencies and flood control agencies, among other stakeholders.
