State-of-the-Art Pressure Pipeline Renovation Methods & Design Considerations

Online Workshop

Part 1: Wednesday March 24, 2021

Part 2: Friday March 26, 2021


Pressure pipelines are used to deliver potable water to homes and businesses and for the pumping of sewage in forcemains. Unlike gravity pipelines, pressure pipelines flow full, have an internal working pressure, and are subjected to pressure cycles.  This course will introduce participants to pressure pipeline design considerations for the installation of a liner on the inside of a deteriorated pressure pipelines. This will be accomplished by a discussion of the recent AWWA Publication “Structural Classification of Pressure Pipelines and Suggested Protocol for Product Classification”, which will be provided to all course registrants prior to the start of the course. It will then discuss, in detail, structural lining systems such as Spray-In-Place-Pipe (SIPP), Cured-In-Place-Pipe (CIPP) and Thermoplastic (HDPE and PVC) liner design methods that include the Hydrostatic Design Basis (HDB) and the ASTM F1216 Non-mandatory Appendix X1.1 design methods. It will also discuss product verification and type testing.  The latest AWWA publications such as the soon to be published M28 Watermain Rehabilitation Manual Version 4 and new CIPP Pressure Pipeline standard will be reviewed along with the new CATT committee developed Ontario Provincial Standard Specifications( OPSS).  Also included will be information on the new Resiline SIPP product, developed in the United Kingdom and piloted in Canada, along with the clean-assess-line and protect method that can offer a potential to drive large cost savings and improve network performance

Dr. Knight is an Associate Professor in the Department of Civil and Environmental Engineering at the University of Waterloo and the Executive Director of the Centre for Advancement of Trenchless Technologies (CATT), also located at the University of Waterloo.  He Chairs the AWWA Watermain Rehabilitation Committee, the AWWA M28 Watermain Rehabilitation Manual Version 4 revision, and the AWWA CIPP Standard development. In addition, Dr. Knight is a member of the AWWA Sliplining Standard committee and the newly formed AWWA M81 Large Diameter Watermain Rehabilitation Committee. An experienced instructor, he has over 15 years of testing and research in watermain rehabilitation products and has recently developed and commissioned a CIPP liner bursting laboratory at the University of Waterloo designed to complete short and long-term burst testing. This course will bring the latest in watermain rehabilitation research and industry best practices together in a single live online workshop. This is a workshop you will not want to miss.
