During these lazy dog days of summer, many of us take a break from our hectic lifestyles and get away for family vacations. If you are anything like me, however, you may find it very hard to completely let go. Along with the beach chair and sunscreen, I usually pack up back issues of Municipal Sewer and Water and other magazines I haven’t had the time to read.

Part of the reason I never quite let go is because I love the work I do. For me, keeping up with underground infrastructure news is not a burden, it’s a pleasure. In addition to magazines and websites, there is another resource available from any place, at any time, and on any web-enabled device: NASSCO webinars.

Over the years we have archived these informative presentations at to educate and — for those of us who get excited about learning new technologies — entertain. This summer, I encourage you to spend some time learning more about trenchless technologies and specifications by visiting our library of webinars at There, you will find valuable resources and webinars including:

NASSCO standard specification guidelines for CIPP, manholes and more

This webinar provides an overview of how the preparation of effective bid specifications are critical to project success. It also provides guidelines to help prepare quality specifications for trenchless technologies. Both CIPP and manhole rehabilitation specification guidelines are discussed, along with the importance of performance-based specifications.

Engineers turn to injection grouting to stop sewer infiltration

As wastewater utilities struggle to control inflow and infiltration in sewer infrastructure, engineers are re-examining trenchless solutions to maximize infiltration reduction, minimize costs and deliver long-term solutions. This webinar examines causes of infiltration, injection chemicals, procedures, specifications, opportunities for value engineering and the role of the inspector to ensure long-term removal of infiltration from the collections system.

Laterals – assessment, rehabilitation and results

Watch this webinar and learn why the Washington Suburban Sanitary Commission (WSSC) chose to perform lateral inspections and rehabilitation, and discover how they performed the work. Highlights include lessons learned along the way and how the process was improved as a result.

The webinars listed above are just a sampling of the many educational resources available to you at You can also find educational videos, including a three-part introduction and overview of PACP; an introduction to sewer cleaning with jetting equipment; and a trailer for a documentary titled Liquid Assets, which tells the story of essential infrastructure systems: water, wastewater and stormwater.

Produced with the general public in mind, this video, in particular, is one that does an excellent job of explaining what we do and why it’s important to our communities. You might even convince your family to watch this one with you.

We plan to continue building this library of resources and are considering other technologies as topics for future webinars, including pressure pipe and laterals. Why do we believe these resources are so important? Because NASSCO’s mission is to set standards for the assessment, maintenance and rehabilitation of underground infrastructure and to ensure the continued acceptance and growth of trenchless technologies, which relies on all of us staying involved and informed.
