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.
