CATT May Be Winding Down but Research at UWaterloo is not.

CATT maybe winding down on April 30, 2022, however research by Dr. Knight and his TEAM at UWaterloo is NOT Winding Down. In fact, the transfer of CATT’s mandate to the new and exciting Canadian Underground Infrastructure Innovation Centre (CUIIC), at the University of Alberta, will allow Dr. Knight more time to focus on existing ongoing research projects and to expand them. These projects include: how to test and design pressure liners used to rehabilitate pressure pipelines; Subsurface Utility Engineering return on investment analysis; Advancing water infrastructure asset management; the Environmental impacts of CIPP lining materials; and pipeline rehabilitation systems testing.

 If you have research, testing or educational needs please feel free to contact Dr. Knight (

Dr. Knight has a 20 plus year track record as an industry leader in the development of custom educational training programs and courses, forensic analysis, expert witness and testimony, testing pipeline rehabilitation materials, verification and validation studies, industry surveys, development of research programs, and the preparation of grants that can offset your research costs. He also develops industry leading design tools such as BOREAID, PPIBOREAID, PPI PACE, HDPEAPP, and CIPPCalc.

CATT Continues to Innovate and to Change

CATT’s mandate, over the past 28 years, has been to serve its members and the public by addressing critical issues facing water, wastewater and storm water pipelines’ installation, assessment, repair, renewal, and asset management. For the past 20 years, CATT’s growth has been driven through Dr. Mark Knight, CATT’s Executive Director, the Board of Directors, and its staff. 

Over the past 20 years the Canadian Trenchless industry has changed. CATT has strived to innovate to adapt to this change.

In the Fall of 2021, CATT’s Board started to investigate what CATT 3.0 would look like. This review was undertaken to ensure that CATT remained to be a relevant organization to its members, in a changing and growing industry.  The Board held many meetings and had open and frank discussions, consulted with many industry professionals that included Dr. Alireza Bayat, at the University of Alberta.  Dr. Bayat is a faculty member in the Department of Civil and Environmental Engineering and University of Waterloo Alumni. These discussions led to the birth of the Canadian Underground Infrastructure Innovation Centre (CUIIC), at the University of Alberta.  This new centre is envisioned to become a national and international leader in sustainable underground infrastructure innovation, research, and education. More information on this new centre is provided in the one-page pamphlet.  The University of Alberta is fully committed to financially support this new and exciting initiative. Industry has also committed significant seed funding. In May 2022 membership opportunities will be available to join, participate and support this exciting new organization. 

On March 2, 2022, CATT members approved the CATT Board of Directors motion to dissolve CATT on April 30, 2022 and to encourage CATT members to join CUIIC at the University of Alberta.  So what does this mean? CATT activities at the University of Waterloo will end on April 30, 2022. Thus, our last event will be the 2022 TRSBC Trenchless Roadshow, that will be held April 24 to 26 in Kelowna BC. 

CUIIC is committed to continue and to expand CATT’s mandate.  Although the location and name maybe changing, it is important to note that CATT’s original vision and mandate will carry on and evolve, just as it has since 1994 when CATT was formed.

A lot of work has been done and is currently ongoing to get CUIIC up and running as a soon as possible. More details on CUIIC will be provided as soon as possible.
