Centralized Backup & Configuration For Remote Plant HMIs

By Christopher Little, Trihedral Engineering Ltd.

As Wastewater Manager for four sewage treatment plants spread across Colchester County, Nova Scotia, Nicole MacDonald faced the daunting task of ensuring all systems continued to function seamlessly on a 24/7 basis. Each plant had its own separate monitoring and control system that allowed it to function autonomously. What MacDonald really wanted was to be able to monitor all four plants and make configuration changes from her office. After reviewing her existing infrastructure, she saw the potential to transform these four systems into one unified solution that would also address long standing issues such as remote data backup and automatic system failover. Engineers from Trihedral Engineering Limited worked closely with MacDonald to bring her idea into reality.
