NLS Engineering was retained by the Region of Waterloo to upgrade SCADA IT infrastructure and software at the Galt WWTP & Preston WWTP. This project includes consolidating ~20 SCADA servers to a VMware environment with high availability and disaster recovery. New Layer 3 switches were also implemented. As part of this project, we also upgraded all iFix and Proficy Historian software to current versions, and implemented GE’s new license server. Win911 was updated to the latest version.
Virtualization in a SCADA environment requires extensive knowledge and experience across both SCADA and IT. The Region saved a significant amount of money by implementing virtualization versus like-for-like server replacements, and now the infrastructure is more secure, flexible and scalable.
