She is a NASSCO PACP, MACP and LACP certified trainer for the coding, assessment and condition classification of sewers. Tanya has developed CCTV data driven performance models for the rapid and effective measurement and reporting of severity, extent and distribution of wastewater collection system defects. She has experience in providing renewal recommendations and has developed processes to automate the recommendation process. Also certified in the Inspection Training and Certification Program for the inspection of CIPP installation and manhole rehabilitation technologies. Tanya is the newest board member of the Centre of Advancement of Trenchless Technologies (CATT) and an Applied Science Technologist with the Ontario Association of Certified Engineering Technicians and Technologists (OACETT) in the Geomatics discipline.

Patrick is an Engineer with over 10 years' experience in construction and engineering. He has been involved in a variety of trenchless projects, having the opportunity to learn first-hand from industry leading experts on best practices. His experience in trenchless rehabilitation projects includes advanced industry knowledge in contract administration, specification and tender development, condition assessment, and QA/QC of sewer, trunk sewer, watermain, and MH condition assessment and rehabilitation projects. Patrick has also been an active participant in CATT over the years having presented at numerous past seminars on various Trenchless Technologies.

Chris has been working for the Region of Peel within the Wastewater Dept since 2005. I started out my career as a Water/ Wastewater Operator working on a sewer truck responding to customer issues with sewer lateral backups and other sewer related issues. Over the years in the field I also ran various types of sewer cleaning equipment like Vactor Flusher Combo’s and Power Rodders and still hold Level 3 MOE Operator Certifications in both Wastewater Collection and Water Distribution. I am currently a Project Manager within the Wastewater Division and work on special projects for both the Director of Wastewater and the General Manager of Water and Wastewater.

Robert Lee was born in Nowra, Australia where he grew with a passion for photography and was heavily inspired by Google Streetview to map the world. He went on to study and graduate from the University of Wollongong with a degree in Geoscience. This degree led Robert to work in roles such as a geophysicist, geologist and photogrammetrist. 

Over the years Robert spent his working life in and around underground environments where he developed 3D mapping systems to scan underground infrastructure. In 2013 he founded his first company GeoInteractive that specializes in mapping underground mines. Robert and his company was recognised as an innovator and was accepted in several accelerators where he refined his business model and technology. The accelerators also introduced him to the US market where he then packed up his belongings and moved to the midwest region of America to focus on mapping out the aging wastewater networks. He setup and founded an award winning company called Subterra AI. 

Subterra AI is headquartered in CIncinnati and streamlines how municipalities inspect and manage their underground wastewater network through the use of their advanced inspection technologies coupled with a cloud platform called Terralytics™.
