Co-Chair (volunteer)
ISA112 SCADA Systems Management Committee
Guelph, Ontario, Canada

Graham Nasby is an industry-recognized leader in the OT (operational technology), SCADA, and industrial automation sector for his efforts in cyber security best practices, standards development, alarm management, and operational efficiency. Through his work with ISA, CSA, ANSI and the IEC, he has co-authored international standards on systems design, cyber security, industrial automation, alarm management, and HMI systems. Graham has multi-industry experience, ranging from technical to project/program management, in the pharmaceutical, water/wastewater, nanotechnology, process, and rail transport industries. His background includes operations, capital projects, construction, program development, and developing long term technology roadmaps. As a technical and thought leader, Graham is a frequent author of industry articles and invited speaker at industry events.

From 2010 to 2022, Graham Nasby worked in the municipal water sector and was an active member of the ISA Water/Wastewater Division. Currently he writes a column for the ISA water/wastewater division newsletter. During his time in the sector, Graham was involved with international committees of the ISA, AWWA, WEF, as well as local committees in Ontario, Canada, including the OWWA and WEAO. From 2012-2013 he was the General Symposium Chair for the ISA’s Water/Wastewater and Automatic Controls Symposium, from 2013-2015 he held the post of WWID Director, and from 2011-2022 he held the position of WWID’s newsletter editor. During this time he also served on the OWWA’s Automation Committee, the WEF Information Technology Committee, and the AWWA’s operational technology and cybersecurity committees.  Graham could also be frequently heard at water/wastewater industry events at a local, regional, national and international level.

In mid-2022, Graham decided to take on the challenge of moving to a new industry, and now holds a senior management role at one of North America’s largest Class 1 railways where he continues his work promoting cybersecurity best practices, fostering operational effectiveness, and protecting critical infrastructure.  More information about his current role can be found on his LinkedIn profile at:

“It has been a pleasure to involved in the early days of building up our ISA Water/Wastewater Division into one of ISA’s most active and involved technical divisions. I would like to thank the volunteer team of the WWID for continuing to provide both an excellent member, volunteer, and industry partner experience for everyone  involved. Please keep up all the good work!”

During his time in the municipal water/wastewater sector, here a few of the presentations, articles and other publications Graham Nasby has been involved with:
