CIPP Reunion to Celebrate 50th Anniversary, Pioneers

A technology that forever changed the face of infrastructure rehabilitation, and launched a wildly successful and beneficial market will celebrate its 50th anniversary at the annual Underground Construction Technology Conference & Exhibition, July 13 – 15 in Nashville, Tenn. 

Eric Wood

In conjunction with UCT and Underground Construction, a cured-in-place pipe (CIPP) industry committee has developed a special 50th CIPP Celebration reception that will honor two Pioneers of CIPP. Also, a unique educational program track will review and reflect upon the history of CIPP, plus project upon the continued successes of CIPP. 

CIPP founder Eric Wood will be honored, posthumously, along with Bob Affholder of SAK, as the first Pioneers of CIPP. These two individuals, widely credited with the creation and expansion of the technology, will be awarded during the special CIPP 50 Celebration on Tuesday evening, July 13.

The event will also serve as a reunion for the thousands of people who have worked in the CIPP industry and continue to proudly serve in the market. Geared for old-timers and newcomers, all participants in CIPP are welcome at the reception to honor the Pioneers, relive historic challenges and predict the future of this disruptive technology. 

In announcing this first-ever CIPP Celebration, industry organizers project it will be an opportunity to bring all the seasoned, current and future industry participants together for a look back – and forward – at the amazing CIPP industry. Whether you are long-since retired or a recent entry into the market, this is an event that honors CIPP. 

To sponsor this special CIPP event and reunion, contact Jenna Rutan,, (713) 520-4413.  


CIPP 50th Celebration Education Program 

Tuesday, July 13 

  • Keynote: From the Beginning: A Public Sector Perspective

Speaker: Richard Thomasson, Sr Project Manager, EBA Engineering 

The Washington Suburban Sanitary Commission (WSSC) was one of the first public utilities to extensively use CIPP in North America. In the late 1970s Richard Thomasson was a young engineer working for WSSC. As fate would have it, he helped manage WSSC’s early CIPP work and was on the job site for the first several installations. A trenchless technology advocate for over four decades, Thomasson brings a unique perspective to those early years and how an aggressive CIPP installation company and a large public utility helped launch an industry. 

  • CIPP: Then and Now

Although the basic concept of CIPP has not changed since the 1970s, the materials, installation techniques and equipment have improved and changed dramatically. CIPP installations have gone from inception to a multi-billion-dollar-a-year industry. This presentation takes a look back at the evolution of product application, installation and cure procedures and the associated equipment and materials, that have been developed specifically for the CIPP industry. 

  • New ASCE Standard for Design of Close-Fit Liners

ASCE MOP 145 is a state-of-the-art source for the design of flexible, close-fit linings for the rehabilitation of pipes designed for gravity flow such as sanitary sewers, culverts, and storm sewers. The design solutions cover both circular and non-circular pipe geometries, including non-standard non-circular pipe geometries. 

  • Aerial, Gas, Light & Water: Diversification of CIP, which includes three segments:

The Evolution of CIPP for Fully Structural Pressure Pipe Renewal 

CIPP was first introduced in the UK in 1971 to repair an aged gravity flow sewer line as an alternative to dig and replace methods. This was followed by its utilization in low-pressure, such as sewer force mains, in the 1980s. It, in turn, led to the development of ASTM standard F1216 in 1989, which included non-mandatory design considerations in Appendix X1. Reinforced CIPP first emerged in North America in 1998 and has since evolved into the most widely utilized, fully structural pressure pipe technology on the market. An overview of current products, capabilities, standards, design methods and industry developments and will be presented and discussed. 

Aerial Gravity Pipe Rehabilitation using Fiber-Reinforced CIPP 

With the UV-Light cured, glass fiber CIPP solutions, the ability to design a fully structural rehabilitation of an existing gravity sewer pipe is now possible. This presentation will present the particulars of designing a 24" diameter liner to support a 24" concrete cylinder pipe supported on piers at 32' on-center. 

Trenchless Reconditioning of Natural Gas Pipelines via Cured-In-Place Lining 

CIPL technology is effective and cost competitive for metallic gas pipeline rehabilitation. Ideal applications include difficult-to-access areas such as bridges, highways, railroad crossings, heavily trafficked roadways and historic areas. Discussion will include history, testing and application, with a case study example of PPM’s world-record lining of a 42” pipeline in East Orange, NJ.
