SCWWA’s status report notes several IT and OT upgrades: replacement of the Storage Area Network (SAN) equipment, replacement of the server room IT switch, installation of OT firewalls and two OT switches for the OT server room, and coordination of fiber optic arc flash protection installation that required a Dominion Power outage. These changes are part of a broader effort to modernize the Authority’s network and control-system backbone in support of the ongoing Nutrient Reduction Project and other operations. Specific vendors are not named for this IT work, but it indicates active investment in cybersecurity, resiliency, and segmented OT networks.While the current replacements appear underway or recently completed, they create a base of modern hardware that will need ongoing support, cybersecurity management, and possible expansion as new process areas come online. IT and SCADA vendors can use this as intelligence on the Authority’s technology refresh cycle and position for future projects such as backup/DR solutions, network monitoring, security assessments, and integration of additional process equipment into the hardened OT environment.

Fiber optic arc flash protection installation required coordination of a Dominion Power outage, suggesting substation or main feed protective relays are being upgraded alongside IT infrastructure.
